I don't know how to tell you this...but you're wrong.

Actually, I know exactly how to tell you; you're wrong. It doesn't matter if your facts are all correct, you have all the evidence in the world, and you've been able to shoot down every argument they have. You're still wrong. Why, you ask? Because you're missing the point. The point of life, and even less so the point of following Christ, is not to be able to prove that you're right.
