The way we're usually told it works is this: receive a vision for where you want to go, then formulate a mission to get there.
I don't see that in the Bible as the task of the pastor. (Sorry.)
Instead I think the mission comes first, which is to say God's mission comes first. It's not my vision -- for a bigger church, for revival, for whatever -- I want to put my church on mission toward; it's God's mission I want a vision for, and his mission I want to shepherd my church to joining.
The mission is the vision.
But of course this requires reframing success as faithfulness and health, not as . . . well, "success."
