What Are the Steps in the Oxygen Pressure Swing Adsorption Process?

Posted by Shirley Xin on May 30, 2025 at 4:02am in Blogs

Introduction to Oxygen Pressure Swing Adsorption

Oxygen pressure swing adsorption (PSA) is a widely used technology for separating oxygen from air to produce high-purity oxygen gas. This process is efficient, cost-effective, and environmentally friendly, making it ideal for industries such as medical, chemical, and metallurgy. Unlike cryogenic distillation, which is energy-intensive, oxygen pressure swing adsorption leverages the selective adsorption properties of materials to isolate oxygen at ambient temperatures. This article outlines the key steps involved in the oxygen pressure swing adsorption process, providing a clear and objective understanding of its mechanics and applications.

What is Pressure Swing Adsorption?

Pressure swing adsorption is a gas separation technique that uses adsorbent materials, such as zeolites or activated carbon, to selectively capture specific gases from a mixture. In the context of oxygen pressure swing adsorption, the goal is to separate oxygen (O₂) from nitrogen (N₂) and other trace gases in atmospheric air. The process operates by cycling between high-pressure adsorption and low-pressure desorption phases, exploiting differences in the adsorption affinities of gases under varying pressures.

The oxygen pressure swing adsorption process is highly efficient because it can be performed in compact systems, making it suitable for both large-scale industrial applications and smaller, on-site oxygen generators. Companies like Hangzhou Z-Oxygen Intelligent Device Co., Ltd utilize this technology to provide tailored solutions for oxygen generation across various industries.

Key Steps in the Oxygen Pressure Swing Adsorption Process

The oxygen pressure swing adsorption process involves a series of well-defined steps that ensure the continuous production of high-purity oxygen. These steps are typically performed in two or more adsorption columns to maintain a steady output. Below, we break down the process into its core stages.

1. Air Compression and Pre-Treatment
The oxygen pressure swing adsorption process begins with the compression of ambient air. Atmospheric air, which contains approximately 21% oxygen, 78% nitrogen, and trace amounts of other gases (e.g., argon, carbon dioxide, and water vapor), is drawn into the system and compressed to a pressure typically between 4 and 10 bar. This compression increases the concentration of gas molecules, facilitating effective adsorption.

Before entering the adsorption columns, the compressed air undergoes pre-treatment to remove impurities that could damage the adsorbent material or reduce efficiency. This involves:

Filtration: Removing dust, oil, and particulate matter using compressed air filters.
Moisture Removal: Using dryers to eliminate water vapor, as moisture can degrade the performance of adsorbents like zeolites.
Carbon Dioxide Reduction: In some systems, additional filters reduce CO₂ levels to prevent competition with oxygen during adsorption.

Pre-treatment ensures that the air entering the oxygen pressure swing adsorption system is clean and dry, optimizing the performance of the adsorbent material.

2. Adsorption Phase
In the adsorption phase, the pre-treated, compressed air is directed into an adsorption column filled with a selective adsorbent, typically a zeolite molecular sieve. Zeolites are highly porous materials with a strong affinity for nitrogen due to their molecular structure. In oxygen pressure swing adsorption, the zeolite preferentially adsorbs nitrogen molecules while allowing oxygen and other non-adsorbed gases (e.g., argon) to pass through.

During this high-pressure phase, the following occurs:

Nitrogen molecules are trapped on the surface of the zeolite, reducing the nitrogen content in the gas stream.
Oxygen, which has a lower adsorption affinity, flows through the column and is collected as the product gas.
The output gas typically achieves an oxygen purity of 90–95%, suitable for most industrial and medical applications.

The adsorption phase continues until the zeolite becomes saturated with nitrogen, at which point the column can no longer effectively separate oxygen. To maintain continuous operation, the system switches to a second adsorption column while the first undergoes regeneration.

3. Depressurization and Desorption
Once the adsorbent in the first column is saturated, the oxygen pressure swing adsorption process transitions to the depressurization and desorption phase. The column is isolated from the compressed air feed, and the pressure is rapidly reduced, often to near-atmospheric levels. This pressure drop causes the adsorbed nitrogen to be released from the zeolite, a process known as desorption.

Depressurization is critical because it regenerates the adsorbent, preparing it for the next adsorption cycle. The released nitrogen, along with other trace gases, is vented to the atmosphere or, in some systems, collected for further use (e.g., in nitrogen PSA systems). The desorption phase ensures that the zeolite regains its capacity to adsorb nitrogen, making the oxygen pressure swing adsorption process cyclical and sustainable.

4. Purge and Pressure Equalization
To enhance efficiency, many oxygen pressure swing adsorption systems include a purge and pressure equalization step. During the purge phase, a small portion of the high-purity oxygen produced from the active column is redirected to the regenerating column. This oxygen flow helps "purge" residual nitrogen from the zeolite, ensuring thorough regeneration.

Pressure equalization is another optimization technique. Before fully depressurizing, the high-pressure gas from the saturated column is transferred to another column that is about to begin adsorption. This reduces energy losses and stabilizes the pressure across the system, improving the overall efficiency of the oxygen pressure swing adsorption process.

5. Cycle Repetition
The oxygen pressure swing adsorption process is cyclical, with each column alternating between adsorption and regeneration. In a typical two-column PSA system, while one column is adsorbing nitrogen and producing oxygen, the other is depressurizing and regenerating. The cycle time is carefully controlled, often lasting only a few minutes, to ensure continuous oxygen production.

Advanced oxygen pressure swing adsorption systems may use multiple columns or sophisticated control algorithms to optimize cycle timing and energy consumption. This ensures a steady supply of oxygen with minimal downtime or fluctuations in purity.

Advantages of Oxygen Pressure Swing Adsorption

The oxygen pressure swing adsorption process offers several benefits, making it a preferred choice for oxygen generation:

Energy Efficiency: Compared to cryogenic distillation, PSA requires less energy, as it operates at ambient temperatures and moderate pressures.
Compact Design: PSA systems are compact and scalable, suitable for both large industrial plants and portable oxygen generators.
Cost-Effectiveness: The use of durable adsorbents like zeolites reduces maintenance costs, and on-site generation eliminates the need for oxygen transportation.
High Purity: Oxygen purity levels of 90–95% meet the requirements of most applications, including medical oxygen supply.

Applications of Oxygen Pressure Swing Adsorption

Medical Oxygen Supply: PSA systems provide medical-grade oxygen for hospitals and clinics, especially in remote or resource-limited areas.
Industrial Processes: Oxygen is used in chemical manufacturing, metal cutting, and wastewater treatment.
Aerospace and Defense: PSA systems supply oxygen for high-altitude operations and emergency response.
Environmental Applications: Oxygen enhances combustion efficiency in incinerators and supports ozone generation for water purification.

Challenges and Considerations

While oxygen pressure swing adsorption is highly effective, it has some limitations. The process typically produces oxygen with a purity of up to 95%, which may not suffice for applications requiring ultra-high purity (e.g., semiconductor manufacturing). Additionally, the performance of PSA systems depends on the quality of the adsorbent and the precision of cycle control. Regular maintenance, such as replacing filters and monitoring adsorbent degradation, is essential to ensure consistent performance.

Conclusion

Oxygen pressure swing adsorption is a robust and efficient technology for producing high-purity oxygen from atmospheric air. By cycling through compression, adsorption, depressurization, and regeneration, PSA systems deliver a reliable oxygen supply for diverse applications. Its energy efficiency, compact design, and cost-effectiveness make it an attractive solution for industries worldwide.

Carnal vs Spiritual

Posted by Apostle Lee on May 25, 2025 at 12:34pm in Blogs

Greetings in The Mighty Name of Jesus, The Christ!!!

Carnal vs Spiritual

Brothers and Sisters, do you know the Difference from Living a Carnal Life verses a Spiritual Blood Bought Life? One has Our Lords Blessings, the other has not.

Matthew 7:21-23 KJV

"²¹ Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven. ²² Many will say to me in that day, Lord, Lord, have we not prophesied in thy name? and in thy name have cast out devils? and in thy name done many wonderful works? ²³ And then will I profess unto them, I never knew you: depart from me, ye that work iniquity."

What Carnal “Christians” Life can have Power and Authority by The Name of Jesus Only and some by the Power and Authority of Satan. The Two can be confusing, but by The Holy Spirit we can Discern them. There are many who Walk among the True Born Again, Blood Bought, who Confess and Walk as though they are Saved By Grace. But as Our Lord Jesus has said, He does not KNOW Them.

Luke 17:33-36 KJV

"³³ Whosoever shall seek to save his life shall lose it; and whosoever shall lose his life shall preserve it. ³⁴ I tell you, in that night there shall be two [men] in one bed; the one shall be taken, and the other shall be left. ³⁵ Two [women] shall be grinding together; the one shall be taken, and the other left. ³⁶ Two [men] shall be in the field; the one shall be taken, and the other left."

The Carnal Christian Living will not be Saved!!! They will be left behind, I believe that only a Life turned completely to Walk as Jesus has said, that they giving their Lives 100%, might be saved by Martyrize. The reason for the “might be saved”, is because of the Rapture that is to come. Some say that in the Book of Revelations The Church is no longer mentioned after the Third Chapter, I must agree, but what happens after that is Martyrize, people dying because they Confess Jesus as Their Lord.

We must understand The Coming Of Jesus, for Jesus said that there would be things that will point to His Coming…

Matthew 24:6-14 KJV

"⁶ And ye shall hear of wars and rumours of wars: see that ye be not troubled: for all [these things] must come to pass, but the end is not yet. ⁷ For nation shall rise against nation, and kingdom against kingdom: and there shall be famines, and pestilences, and earthquakes, in divers places. ⁸ All these [are] the beginning of sorrows. ⁹ Then shall they deliver you up to be afflicted, and shall kill you: and ye shall be hated of all nations for my name's sake. ¹⁰ And then shall many be offended, and shall betray one another, and shall hate one another. ¹¹ And many false prophets shall rise, and shall deceive many. ¹² And because iniquity shall abound, the love of many shall wax cold. ¹³ But he that shall endure unto the end, the same shall be saved. ¹⁴ And this gospel of the kingdom shall be preached in all the world for a witness unto all nations; and then shall the end come."

Everyone looks at verses 6 – 8 not reading the rest of What Jesus said MUST happen before His 2^nd Coming. For whatever reason, many believe they will not suffer Affliction or be Killed for Their Faith or be Hated by Everyone. Jesus said that verses 6 – 8 are ONLY the Beginning Of Sorrows. A True Born Again, Blood Bought would Suffer such things, but someone who is Carnal would not, for they do not have a Relationship With Jesus!

Now, Brothers and Sisters, do you yet Walk As Carnal having split making of one’s own body separate from others, saying that You are The Church, The Body Of Christ!!! For those who are Spiritual see that Anyone who confesses Jesus as Savior and Lord and Walks Therein, are The True Church, for they See NO Walls that divide them, nor do they See No Denomination that Separates them! Paul spoke of such that we Must be aware of…

1 Corinthians 3:1-8 KJV

"¹ And I, brethren, could not speak unto you as unto spiritual, but as unto carnal, [even] as unto babes in Christ. ² I have fed you with milk, and not with meat: for hitherto ye were not able [to bear it], neither yet now are ye able. ³ For ye are yet carnal: for whereas [there is] among you envying, and strife, and divisions, are ye not carnal, and walk as men? ⁴ For while one saith, I am of Paul; and another, I [am] of Apollos; are ye not carnal? ⁵ Who then is Paul, and who [is] Apollos, but ministers by whom ye believed, even as the Lord gave to every man? ⁶ I have planted, Apollos watered; but God gave the increase. ⁷ So then neither is he that planteth any thing, neither he that watereth; but God that giveth the increase. ⁸ Now he that planteth and he that watereth are one: and every man shall receive his own reward according to his own labour."

I tell you now, anyone who Holds to Any Denomination, Holds to Their Teaching, is yet a Babe In Christ!! For you Believe more in these things then What The Word says HOW WE The Church are to be. You have Chosen to Separate yourselves not because of Jesus, but because of Your Flesh, being yet Carnal!!! Consider the below Scriptures that in part, tells HOW WE are to be…

Ephesians 4:3-6 KJV

"³ Endeavouring to keep the unity of the Spirit in the bond of peace. ⁴ [There is] one body, and one Spirit, even as ye are called in one hope of your calling; ⁵ One Lord, one faith, one baptism, ⁶ One God and Father of all, who [is] above all, and through all, and in you all."

The Carnal Mind fights against these Scriptures, but the Spiritual Minded Embraces these Scriptures understanding that those who Truly ask Jesus to be Their Savior and Lord knows by The Holy Spirit the Truth!!!

I have many, many Brothers and Sisters who Follow The Scriptures who are part of a Denomination, only to bring The Truth to Light. They Fight by The Sword, Hoping they will turn some from the Will of Man and Satan and Turn to Jesus as Savior and Lord of Their Lives!

We must Understand that to be Carnal is Death and to be Spiritual is Life, that Jesus is Not Split, having many Brides, but has Only One Bride and that Bride does The Will Of The Father every day!!

Matthew 7:21 KJV

"Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven.”

Those who are of The Spirit Understands Why the Offices that Jesus set are so important, that again they Embrace The Word and Hold it True to One Faith In Jesus! But the Carnal Mind CANNOT Understand the things that are Spiritual for they must be Transformed Into Christ by the Renewing of their Minds. For many of you still do not Understand the following Scripture, but hold that it is instant when it is not!!

2 Corinthians 5:17 KJV

“Therefore if any man [be] in Christ, [he is] a new creature: old things are passed away; behold, all things are become new."

The Carnal sees this as if you are Saved then You are all brand new, Completely, but if that where the case we would not need any other Scriptures telling us How To Live In Christ! Paul said that Our Minds have to be Renewed by Having The Truth to be Taught to us, that we will Change from Carnal to Spiritual!

Romans 12:1-2 KJV

"¹ I beseech you therefore, brethren, by the mercies of God, that ye present your bodies a living sacrifice, holy, acceptable unto God, [which is] your reasonable service. ² And be not conformed to this world: but be ye transformed by the renewing of your mind, that ye may prove what [is] that good, and acceptable, and perfect, will of God."

The Carnal MUST be Transformed to The Mind of God to Walk Spiritually!!! Being Carnal Minded does not Allow you to See Spiritual things in them or around them, they must always deal with Logic to have an Understanding. Jesus is very Logical, but it is a Logic that is Spiritual not Carnal. There are things that the Carnal Mind just cannot comprehend, that they Ignore what Scripture says or are Taught by those in the Flesh Not to Accept or To Accept a Different Definition of what The Truth Of The Word says! I was and still am, being Taught By The Holy Spirit the Truth, I did not go to Seminar as most have, but for me, I was told specifically not to go, because The Truth was turning to Lies and Fables!!!

I pray every day that The Church would be One and not Fragmented as it is, sadly to say, it never will be. But, My Fight, My Calling, will not change from The Truth, I try to Live The Truth and I will Die In The Truth and be Renewed In Heaven!!

Brothers and Sisters, the Age of The Gentiles is coming to a close, time is running out, those who Chose to be Carnal Minded will Not be caught up with Our Lord Jesus when He comes for His Bride, only the Spiritual Minded!!!

Matthew 25:1-12 KJV

"¹ Then shall the kingdom of heaven be likened unto ten virgins, which took their lamps, and went forth to meet the bridegroom. ² And five of them were wise, and five [were] foolish. ³ They that [were] foolish took their lamps, and took no oil with them: ⁴ But the wise took oil in their vessels with their lamps. ⁵ While the bridegroom tarried, they all slumbered and slept. ⁶ And at midnight there was a cry made, Behold, the bridegroom cometh; go ye out to meet him. ⁷ Then all those virgins arose, and trimmed their lamps. ⁸ And the foolish said unto the wise, Give us of your oil; for our lamps are gone out. ⁹ But the wise answered, saying, [Not so]; lest there be not enough for us and you: but go ye rather to them that sell, and buy for yourselves. ¹⁰ And while they went to buy, the bridegroom came; and they that were ready went in with him to the marriage: and the door was shut. ¹¹ Afterward came also the other virgins, saying, Lord, Lord, open to us. ¹² But he answered and said, Verily I say unto you, I know you not."

Five were Carnal, Five were Spiritual, both were called Virgins! Some of you have been fighting with your own selves to Leave those who Walk Carnal, you need to do so before you can ever mature as a Bride Of Christ! Understand this, that We, The Church, The Blood Bought, The Born Again, are to be Separated from The World, for The World is Carnal Minded and We are to be Spiritual Minded…

Consider the below Scriptures, many think it deals with only Marriage, but it deals with The Body Of Christ as a whole, in How we are Living.

2 Corinthians 6:14-18 KJV

"¹⁴ Be ye not unequally yoked together with unbelievers: for what fellowship hath righteousness with unrighteousness? and what communion hath light with darkness? ¹⁵ And what concord hath Christ with Belial? or what part hath he that believeth with an infidel? ¹⁶ And what agreement hath the temple of God with idols? for ye are the temple of the living God; as God hath said, I will dwell in them, and walk in [them]; and I will be their God, and they shall be my people. ¹⁷ Wherefore come out from among them, and be ye separate, saith the Lord, and touch not the unclean [thing]; and I will receive you, ¹⁸ And will be a Father unto you, and ye shall be my sons and daughters, saith the Lord Almighty."

The Mature needs to Fight for the Carnal, that they will Become Spiritual Minded and not just for the lost, for they are but a little above them! For all who are Carnal will be left behind!! You can Believe whatever you want, but The Word, The Holy Spirit and The Father all agree…Do You?

Amen and Amen!!!

What are the Advantages and Disadvantages of Six Common Valves?

Posted by brina lee on May 22, 2025 at 12:01am in Blogs

There are many types of valves, each with its own advantages and disadvantages. Below is an analysis of six major valves, including gate valves, butterfly valves, ball valves, check valve, globe valves, and plug valves. We hope this will be helpful to you.

1 Gate Valve.

A gate valve is the valve where the closing member (gate) moves perpendicular to the axis of the pipeline. It is mainly used to cut off the medium, i.e., for fully open or fully closed operation. Generally, gate valves are not used for flow regulation. They can be applied to low-temperature and low-pressure systems as well as high-temperature and high-pressure systems, but are typically not used in pipelines conveying media such as mud.

Advantages:

① Low fluid resistance;
② Requires less torque to open and close;
③ Can be used in loop pipelines where the medium flows in both directions, i.e., the flow direction of the medium is not restricted;
④ When fully open, the sealing surface is less eroded by the working medium compared to globe valves;
⑤ Simple in structure and good in manufacturability;
⑥ Short structural length.

Disadvantages:

① Large external dimensions and opening height, requiring more installation space;
② During opening and closing, the sealing surfaces rub against each other, causing significant wear, and are prone to galling at high temperatures;
③ Most gate valves have two sealing surfaces, increasing the difficulty of processing, grinding, and maintenance;
④ Long opening and closing time.

2 Butterfly Valve.

A butterfly valve is a valve where a disc-shaped closing member rotates approximately 90° to open, close, and regulate the fluid.

Advantages:

① Simple structure, small volume, light weight, and material-saving;
② Quick opening and closing with low flow resistance;
③ Can be used for media with suspended solid particles, and depending on the strength of the sealing surface, it can also be used for powdery and granular media. Suitable for two-way opening/closing and regulation of ventilation and dust removal pipelines, widely used in gas pipelines and waterways in metallurgy, light industry, power, petrochemical systems, etc.

Disadvantages:

① Narrow flow regulation range – when opened to 30%, the flow rate is already over 95%;
② Due to structural and sealing material limitations, it is not suitable for high-temperature and high-pressure pipeline systems. Generally, the working temperature is below 300°C, and the pressure rating is below PN40;
③ Relatively poor sealing performance compared to ball valves and globe valves, so it is used in places with less strict sealing requirements.

3. Ball Valve.

A ball valve evolved from a plug valve, with a spherical closing member that rotates 90° around the valve stem axis to achieve opening and closing. Ball valves are mainly used in pipelines to cut off, distribute, and change the flow direction of the medium. Ball valves designed with a V-shaped opening also have good flow regulation capabilities.

Advantages:

① Extremely low flow resistance (practically zero);
② Reliably applicable to corrosive media and low-boiling liquids as it does not get stuck (when used without lubricant);
③ Achieves complete sealing over a wide pressure and temperature range;
④ Enables fast opening and closing – some structures can open/close in only 0.05–0.1 seconds, making them suitable for automated systems in test benches. No impact during fast operation;
⑤ The spherical closing member automatically positions at the extreme positions;
⑥ Reliable double-sided sealing for the working medium;
⑦ When fully open or closed, the sealing surfaces of the ball and seat are isolated from the medium, so high-velocity media passing through the valve does not erode the sealing surfaces;
⑧ Compact structure and light weight, making it a reasonable valve structure for low-temperature medium systems;
⑨ Symmetrical valve body, especially welded structures, can well withstand stresses from the pipeline;
⑩ The closing member can withstand high pressure differences during closing.
⑪ Fully welded ball valves can be directly buried underground, protecting internal components from corrosion, with a maximum service life of 30 years. They are ideal for oil and natural gas pipelines.

Disadvantages:

① The main seat sealing material for ball valves is polytetrafluoroethylene (PTFE), which is inert to almost all chemicals and has comprehensive properties such as low friction coefficient, stable performance, resistance to aging, wide temperature range, and good sealing. However, PTFE's physical properties – including high expansion coefficient, sensitivity to cold flow, and poor thermal conductivity – require the seat seal design to accommodate these characteristics. Therefore, when the sealing material hardens, sealing reliability is compromised. Additionally, PTFE has a low temperature rating and can only be used below 180°C. Beyond this temperature, the sealing material ages. For long-term use, it is generally limited to 120°C.
② Its regulation performance is inferior to that of globe valves, especially for pneumatic (or electric) valves.

4. Check Valve.

A check valve, also known as a non-return valve or one-way valve, is designed to allow fluid (liquid or gas) to flow in one direction only, preventing backflow.

Advantages:

① The primary function of a check valve is to prevent media backflow, ensuring that fluids in the specified direction and avoiding equipment damage, process abnormalities, and other issues caused by backflow.
② Check valves have a relatively simple design, making installation and maintenance more convenient.
③ They are suitable for various fluid media, such as gases and liquids, and are widely used in both industrial and civil applications.
④ By preventing backflow, check valves reduce pressure fluctuations inside pipelines, extend pipeline service life, and lower maintenance frequency.
⑤ In water supply systems, check valves can reduce the risk of water quality contamination and safeguard household water safety.
⑥ By preventing reverse flow, they reduce waste and losses, offering energy-saving effects.

Disadvantages:

① Check valves generate significant resistance when closing, which may affect fluid flow efficiency.
② In some cases, the sealing performance of check valves may be less than ideal, leading to fluid leakage.

5. Globe Valve.

A globe valve is a type of valve where the closing member (disc) moves along the centerline of the seat. Due to this movement pattern, the change in the seat opening is directly proportional to the disc stroke. As the valve stem has a relatively short opening/closing stroke and provides a reliable shut-off function, and the seat opening is proportional to the disc stroke, this valve is highly suitable for flow regulation. Therefore, this type of valve is ideal for cutting off, regulating, and throttling.

Advantages:

① During opening and closing, the friction between the disc and the valve body sealing surface is smaller than that of gate valves, making it more wear-resistant;
② The opening height is generally only 1/4 of the seat channel, much smaller than that of gate valves;
③ Usually has only one sealing surface on the valve body and disc, making it better in manufacturability and easier to maintain;
④ The packing is typically a mixture of asbestos and graphite, giving it a high temperature rating. Globe valves are commonly used for steam systems.

Disadvantages:

① Due to the change in the medium's flow direction through the valve, the globe valve has a higher minimum flow resistance than most other valve types;
② Slower opening speed compared to ball valves due to the longer stroke.

6. Plug Valve.

A plug valve is a rotary valve with a plunger-shaped closing member that opens or closes by rotating 90° to align or disconnect the channels on the plug and the valve body. Also known as a cock or stopcock, the plug can be cylindrical or conical. It comes in various types, such as straight-through, three-way, and four-way. Its principle is basically similar to that of a ball valve.

Advantages:

① Suitable for frequent operation, with quick and effortless opening/closing;
② Low fluid resistance;
③ Simple structure, relatively small size, light weight, and easy to maintain;
④ Good sealing performance;
⑤ Unaffected by installation direction – the medium can flow in any direction;
⑥ No vibration and low noise.

Disadvantages:

①Large sealing surface area, resulting in high torque and reduced flexibility;
② Limited by body weight, the valve size is restricted;
③In practical use, large-diameter valves must use a backseat plug structure, which easily affects sealing performance.

Moving On

Posted by Apostle Lee on May 18, 2025 at 11:33am in Blogs

Greetings in The Mighty Name of Jesus, The Christ!!!

Moving On

Isaiah 34:1 KJV

“Come near, ye nations, to hear; and hearken, ye people: let the earth hear, and all that is therein; the world, and all things that come forth of it."

Romans 11:36 KJV

“For of him, and through him, and to him, [are] all things: to whom [be] glory for ever. Amen."

Brothers and Sisters, there are many of you who are Stuck, Holding On to those things that need to be let go of, by Not doing so, you curse your very Life! Many things can happen by Not Letting Go and Moving On, it can Open Doors for Satan to Torment you, it can cause early Death, it can bring on Depression, it can Sabotage Your Faith, it can Keep The Blessings Of God from ever Reaching You and many more things can happen!

Some of you Blame Jesus for whatever has taken place in Your Life, becoming the Judge of The Almighty, having No Understanding, No Forgiveness.

There are things that Happen In Life that we do not have an Understanding about, Believing that Faith With Understanding will always have an Answer and Sustain Us, this is False Doctrine!!!

There are those things that Happen that Only Jesus Understands, The Why, We as The Church, must Let Go and Move On, Having this One Understanding that All Things Are In His Control, for Jesus has Conquered Death and HAS the Keys to Death and Hell, Sitting upon The Throne having All Power and Authority, both in Heaven and Earth, being The Judge Of All Things that Man Does or Does Not!!!

Matthew 28:18 KJV

“And Jesus came and spake unto them, saying, All power is given unto me in heaven and in earth."

Ephesians 1:20-23 KJV

"²⁰ Which he wrought in Christ, when he raised him from the dead, and set [him] at his own right hand in the heavenly [places], ²¹ Far above all principality, and power, and might, and dominion, and every name that is named, not only in this world, but also in that which is to come: ²² And hath put all [things] under his feet, and gave him [to be] the head over all [things] to the church, ²³ Which is his body, the fulness of him that filleth all in all."

Brothers and Sisters, be Not Ignorant! Be Not Led Astray because of a Lack of Understanding, but in All Things Give Thanks to Jesus Beyond Understanding!! For we Walk Not by The Flesh, but By Faith and that In The Spirit that many things will happen in this World that can shack Our very Believeth of what we Have Believed!!!

Death of Any One or Any Thing can Produce many inward feels, most Ungodly some of the time. Many Curse Jesus for such things because we have No Understanding to Explain Why it needed to happen and Why Jesus did not Answer Our Prayer of Healing. But Healing can be in Death! This is a Profound thing that has even shaken the Godly to their bones, but some have Remained Stuck in a mindless maze of Pain and Hatred towards Any One or Any Thing that reminds them of the fact of lose.

There are many Scriptures that many Stand On instead of Standing In Jesus whom is Lord Over Your Life!!!

John 14:12-14 KJV

"¹² Verily, verily, I say unto you, He that believeth on me, the works that I do shall he do also; and greater [works] than these shall he do; because I go unto my Father. ¹³ And whatsoever ye shall ask in my name, that will I do, that the Father may be glorified in the Son. ¹⁴ If ye shall ask any thing in my name, I will do [it]."

These Scripture have Turned The Faith of many because they did not Get Their Way, trying to Manipulate Jesus to Keep His Word, lacking Understanding in What Jesus has said in the first place.

Matthew 7:21-23 KJV

"²¹ Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven. ²² Many will say to me in that day, Lord, Lord, have we not prophesied in thy name? and in thy name have cast out devils? and in thy name done many wonderful works? ²³ And then will I profess unto them, I never knew you: depart from me, ye that work iniquity."

James 4:2-3 KJV

"² Ye lust, and have not: ye kill, and desire to have, and cannot obtain: ye fight and war, yet ye have not, because ye ask not. ³ Ye ask, and receive not, because ye ask amiss, that ye may consume [it] upon your lusts."

The one point in these last set of Scriptures, is “…the will of my Father…”, the Will of The Father, the Will of Jesus, is to Walk in Obedience Regardless Of The Out Come! This includes Prayer, Faith, Obedience, Love, Death let All Things be Surrendered unto Jesus according to The Fathers Will. With that being said, there is an Understanding that we must always keep at the forefront of our minds, that is, God Is God and They do not only See the Present, but Our Future and Our Past, the things that They Do we may not ever understand because of that.

Let’s take for an example, two Born Again believers in the Hospital with some type of illness that will cause Death, and both having the same illness, both have many Praying for their Healing, one Dies and the other is Healed, Why? There may be No Earthly Answer to Why, but both have an Answer To Do, that is, Move On. if we so Believe that Jesus died on a cross to take away Our Sins to make a way for us to Enter Heaven, then Why is it when Death comes we throw everything out the window If we do not Get Our Way, is not Jesus still Your Lord? Can Death Separate You From Jesus? We Must Understand this, that the Death of a Born Again or the Death of a Project that all are Accord to Jesus Will, are You still His Bride? If being Jesus Bride, then do you No Longer Believe that He will take care of you, even In Death?

In many things in this World we find that Death Brings Forth Life, IF, Aloud to do so. In Life or Death WE, The Church, Born Again, Blood Bought, must Move On With Jesus to see what He has set before us…TO His Glory!!!

My mother, after many years of suffering, died in my arms. At the point of her passing I had to Release Her into the Hands Of Jesus, having Faith we would meet again in Heaven, it was My Choice, I had to tell her it was alright, to Go Home and not worry about me, then she passed. During the next few weeks many things took place, but one The Lord keeps fresh. I had went to a parking lot and set there for a few hours crying uncontrollably and then The Lord Spoke, “Cry No More and Never Again”, Jesus was Commanding me to Move On, not to Hold to something that wasn’t there any more, but to Look to Him for Whatever He had in store for Just Me. That was Forty-Three years ago and I have not once since Cried for my Mother in her Death. Every now and then a Tear may surface, not in her Death, but only that I miss her and cannot wait to see her again in Heaven, but, I Move On.

Hebrews 11:1-2 KJV

“Now faith is the substance of things hoped for, the evidence of things not seen. ² For by it the elders obtained a good report."

Hebrews 13:20-21 KJV

"²⁰ Now the God of peace, that brought again from the dead our Lord Jesus, that great shepherd of the sheep, through the blood of the everlasting covenant, ²¹ Make you perfect in every good work to do his will, working in you that which is wellpleasing in his sight, through Jesus Christ; to whom [be] glory for ever and ever. Amen."

It has been said by many, “When God close one door, look for another to open”, though this is not in every case, the same Answer Must be done, Move On. But, Understand this, Death did not happen because of Your Faith in Jesus, most of the time, Your Faith since the Beginning of your Accepting Jesus has grown, but is not depleted. Jesus is still Jesus, Lord of lords, King of kings, Savior, His Position has not changed, nor should yours!!!

I have seen Death many, many times and I have seen Life Again many, many times. There are things that We are not to Know or Understand that Jesus Does, but again let Not Your Faith Stumble at What You do Not Understand!!! Move On!!! Some of you Hold On To Death, Worship Death In A Loved One, which is a Sin!!! It is a Lack Of Faith that Death has Replaced, filled with Emotions that Control Your Life, making Jesus Not Your Lord anymore! But Jesus says…

Matthew 24:13 KJV

“But he that shall endure unto the end, the same shall be saved."

What are Your Enduring’s? Whatever it may be, We, Church, are to Endure that Jesus Is Lord and Savior no matter what comes our way. That No Matter What, We, Church, are to continue to Serve Jesus with a Whole Heart, Mind and Physically until We go Home!!!

Death should be a party, a Praise To Jesus, that the Old has Passed and What lies ahead is New, but as always, it is Our Choice on What to Do!!! Stay or Move On!!!

Amen and Amen!!!
