You see a bunch of Christian tees in a department store. You think, "Wow, Christian t-shirts! America must still be Christian!" Or has the gospel been watered down so much that nonchristians don't see you as any different than themselves?
While you're looking at the tees, a Christian song plays on the store's radio. Yet why would nonchristians be interested in listening to music about Jesus, whom the world hates? Or is it that this music isn't really about Jesus at all?
