When a group of people, like a congregation, is up to its collective neck in alligators it can take a while before a good collective decision is made and even more time before there is enough collective will to proceed into the agreed-upon action. There are a lot of good and understandable reasons for this.
I think that coaching is an effective way for the congregation to converse and discern its way through:
1. discerning what's in the swamp, (good or bad? dangerous? useful? how many? how big? can we eat it?...)
2. decision processing, and
Every congregation (and organization or team) can use a coach ... even when it's not in a swamp.
