Christians. Could you be wrong?

I do care whether it is true or not true, it is just the only way I can argue for it is through the Bible.

But that's the entire problem. You have a group of claims that may or may not be true (the Bible). You are trying to determine which claims are true and which are not true. You cannot use the Bible itself to support itself. It's circular reasoning that will always end up in the same spot.
