I always wonder how people can assume all of the Bible can be true when so much of it contradicts itself. Obviously, some of it must be false.

If there are such contradictions. I breifly checked out that link (because I'm at work and can't go through entire web sites) and didn't see anything new, or contradicting. I'll admit there are "problems" that sometimes are difficult to answer, but the majority of "contradictions" that I ever hear about are due to violating one of the rules I cited above of biblical interpretation (context, audience, literary style, etc.)

I'll admit that sometimes there are questions I cannot answer; however out of my experience with the trustworthiness of the bible I can assume there are answers, even if I do not know them.
