We could fill stadiums in every major city with people who have been burned or wounded by bad churches. But you never see them. You never hear them, because the first thing a leaver loses is her voice. In the corners of every city are believers who are no longer visible to churchgoers; they have no platform to speak from, no committee meetings to make their point heard, no friendship with the pastor to get a change made. They are isolated and unorganized. Yet they are an army. In my mind they represent the prophetic hope for the church because they understand perhaps as well or better than anyone what the church needs, where it’s failing and what can make it a place of life and joy again.
