Proverbs 29:18 in the New Living Bible says, "When people do not accept divine guidance, they run wild." It does not mean that those without vision were "screaming Mimi's" running around tearing their hair out or something of that nature. It simply means that those without the revelation of God, those without godly vision, live purposeless lives. Their lives are lived lawlessly and in vanity - without direction. Therefore, for a group to be unified, all must have the same vision of where to go in life. We cannot do that until we all believe the same things.
