The bible is not internally consistent, therefore it is impossible for it to accurately describe a coherent deity. The question is nonsensical on its face. You have to instead start picking and choosing which parts of the bible to believe and which parts to ignore (or trust someone else do to that for you), which is why we have tens of thousands of varieties of christianity.
So you must return to the fundamental question of rationality: what do I think I know, and how do I think I know it? Or more specifically - what is your criteria for deciding that part X of the bible is accurate, and part Y is not? Or alternatively, what is your criteria for deciding to trust Priest A over Theologian B?
Seeing as there is no good physical evidence to make these distinctions, it is appropriate to weigh them as strongly as you'd weigh any other bedtime story. The only remaining question is "How confident am I that my senses are entangled with reality as it actually is, and not the product of hallucination/dark lords of the matrix/other reality-shattering plot twist?" Which really has nothing to do with christianity.
To answer your question: I'd be willing to bet $10 vs my immediate termination that any particular sect of christianity (as defined by the Center for the Study of Global Christianity ) you presented to me is inaccurate. I'd fully anticipate having several hundred thousand dollars afterwards and still be breathing if this was repeated to exhaustion.
A friend recently asked how strongly I believe that my deconversion from Christianity was not a mistake. Here's my response, and for those of you who are not Christians, I'm just wondering what numbers you would give:
"There is a part of me that wants to say the chance is far less than 1 percent. But when I consider what 1% must mean about my ability to follow complex arguments and base my judgement on the right premises, it seems absurd to say that.
Trying to honestly estimate the chance that I'm wrong about the Bible being generally reliable is a fascinating exercise... I know the number is low, but I'm not sure how low.
Today I would give myself a 1 in 20 chance of being wrong. If I were to consider the arguments of 20 other groups similar to Christian theologians, I would probably misunderstand them at least 1 time in 20. After talking with 20 groups that have a very different worldview, I might think they are all are mistaken, but once in a while, maybe 5% of the time, it would actually be me.
Wow, 5%!?! If I convert that into "There is a 5% probability that the God of the Bible exists and will send me to hell", I feel scared. But I know how to cheer myself up: I just say, "No way, the chance I'll end up in hell MUST be less than 5%. After all, the God of the Bible is CLEARLY just a big, mean alpha-monkey and... [rehearse all the atheistic arguments here]".
This back-and-forth from certainty to uncertainty makes me feel like I'm doing something seriously wrong.
So what about you? What chance do you place on some variant of Christianity turning up to be true, and what chance do you think a god of some sort exists?"
Numbers please.
