When I was in grad. school at a Christian university, a friend gave me a fish for my car. As I was putting it on the back of my car (Toytoa Celica GT Liftback) in the parking lot of student housing, a girl walked by and said, "I'd NEVER put one of those on my car!" When I asked why, she said, "Because then I'd have to drive like a Christian!"
What's up with THAT?! If I have perfect theology and completely understand (and agree with) the five points of Calvinism, but drive like a pagan...what good it that?
