Whenever we attempt something of faith that God is leading us to, we should take some serious time to pray and fast about our decision, but then we have to make a choice to go.
You can’t just pray forever and not choose, or not go.
There has to be a point of confirmation in your spirit. And in some instances, like Peter’s last week, God will lead you to a choice, and leave you to use your mind to make it.
The angel brought Peter out of jail and left him in the middle of town. Peter now had to decide on his own, using what knowledge he had, what to do next.
The point is, you can’t just delay what God is calling you to do by saying you are praying about it.
Yes, take time to pray about it, but don’t use that as an excuse for inaction.
