There is a corporate aspect to guidance. We don't often think about how God leads through His people, the body of Christ.
We would be well advised to encourage groups of people who are willing to fast, pray and worship together until they have discerned the mind of the Lord and hear His call.
The Spirit can lead contrary to the available facts or in accord with them. He will implant a spirit of unity when the right path has been chosen and trouble us with relentlessness when we have not heard Him correctly. Unity rather than majority rule is the principle for corporate guidance. Spirit-given unity goes beyond mere agreement.
If you cannot listen to your brother, you cannot listen to the Holy Spirit.
