The children of Israel's forty years in the desert offered the world its first church mission, vision, and values discernment process. A generation wandered around and died in the wilderness, running from its past and scared of its future. I have led plenty of navel-gazing processes in churches, and have observed the same dynamic.
What I have learned is this. Vision does not descend on groups; it usually comes to individuals and then is confirmed by groups. Churches that have good leaders and an urgency about their mission will sail to the stars. Churches that are paralyzed will gain nothing by self-study. They will just use the self-study as a stalling tactic.
