What was the Promise?.  Jesus told the disciples to wait in Jerusalem until they received "power from on high".  

They were in Bethesda when Jesus told them this.

Had they stayed in Bethesda, they would not have received the the Promise.

If we stay in our "Bethesda", we will never receive the Promise of God..."Power from on High".

When God tells you to "GO", you better go...or miss what He has for you.
