A quote from Deliberate Simplicity by Dave Browning.

Dave was leading an organizational meeting in a community where his church was considering planting a church when the following happened...

After sharing with the group our commitment to reach out to lost people, a well-meaning woman raised her hand and asked, "Isn't the church for those of us who are believers?" A hush fell over the room as everyone awaited my response...Little did she know she was surfacing one of the most defining precepts of [our church strategy]. The clarity of my response probably startled her. I said, "NO, the church is not FOR us. The church IS us, but it's not FOR us. We are here for the lost."

That's the business we are in.
