"Rise and go...and he rose and went."

²⁶ Now an angel of the Lord said to Philip, “Rise and go toward the south to the road that goes down from Jerusalem to Gaza.” This is a desert place. ²⁷And he rose and went. And there was an Ethiopian, a eunuch, a court official of Candace, queen of the Ethiopians, who was in charge of all her treasure. 

Philip did not check with his community like we have been admonished to do. This does seem to be a special circumstance since an angel actually spoke to Philip and it was something clearly within what God wants. That said, if an angel speaks to you, I would encourage you to bring it to the community before you dive in. Just saying. This also reveals God's "modus operandi." God very often only gives us a step at a time as He did when He told Abram to go to "a place where I will tell you" revealing it many years later. Or even with the disciples when Jesus said, "Follow me," and gave them no job description. This one-step-at-a-time process keeps us humble and more agenda-less. But boy is it hard.  
God's calling to us is sometimes very uncomfortable and His calling is almost invariably connected to a cost. Philip seems to have been single which would make things easier but Peter, James, John, Matthew, dropped their careers. We should all really aim at responding positively to whatever God puts on our hearts. A song at the Feeding of the Multitude yesterday was, “Lord, I have another ‘Yes’ in my heart.” Are there “Yes’s” that you are holding back because of fear.... or time.... or other priorities, or, or, or?
