What if your church was gone tomorrow?

If your church were to cease to exist tomorrow, what gaps would be left in your community? (book by R. Lewis). I have not read the book, but hope I do. This question fascinates me. I do not think it is THE question for a church to ask. It is not the center of the church, but it is a valid question to ponder. I think that the closer a church is to really being all about God's glory, the greater a real impact they'll have on their community. So what would happen in your community if your church was gone tomorrow (I assume the focus is on the people, not the building).
