From Josh and Sean McDowell’s More Than A Carpenter:

You can laugh at Christianity, you can mock it and ridicule it. But it works. It changes lives. I should say Jesus Christ changes lives. Christianity is not a religion; it’s not a system; it’s not an ethical idea; it’s not a psychological phenomenon. It’s a person. If you trust Christ, start watching your attitudes and actions because Jesus Christ is in the business of changing lives.
