The Bible is the claim, not the evidence

[Bad Writer]

^ Listen, you're a Bible man. If you can prove from the Bible that you're a true christian by passing the Mark 16:17-18 confirmation test, we take your word for it without argument.

Why does he need to show us he's a true Christian? He doesn't need to show us in the Bible where it says his Christianity is true; simply telling us that he's one should suffice anyone. Do you need me to show evidence as to my atheism? Am I also to come up with silly evidence for a claim that needs no investigation? (I think your heart is in the right place, but incendiary challenged won't go anywhere in this type of discussion, especially with someone like SW.)
