This video series is guaranteed to enlighten you from the inside out as you further pursue your speaking and/or ministry assignments.  Glory-B-2-God, our beginning does not dictate or have any authority over our ending; that's your job to Believe, Receive and do the work.  [For we are His workmanship, created in Christ Jesus for good works, which God prepared beforehand that we should walk in them. (Ephesians 2:10)] Take this moment in time and STRETCH to see YOU making greater impact as we learn from those who have gone before us, make the adjustments and allow Holy Spirit to navigate the course forward.  Either way, know that you too were created for Greatness.  ENJOY.

When you are anointed and supernaturally gifted and called by God for greatness there are times when others will recognize your gifts. As you mature in your gift you will discern spirits that your adversary will launch against your ideas and dreams for the purposes of exploiting your gift for their carnal benefit. These spirits will often try to capitalize on your immaturity, angst and excitement. In their attempt to swindle you out of your gifts identify what it is that you need to catapult your dream and then make promises that they never intend to deliver upon. Sold “pipe dreams” which is exactly what happened to me.
Promises, promises, promises!
“You‟ll never amount to anything!” “That idea is silly!” “Do you really think YOU'RE capable of that? Where do I begin to tell the story…So many stories, so many events, and so many casualties but as I look closely there are also very many victoriesMY PIPE DREAM IS NOW MY REALITY!!!
