Thanks for the well written reply on this subject. I have a little trouble figuring out if my own experience matches this process or not. I have gone over Christian claims in the past, but they were all in the distant past. Do you think it would makes sense to go through it all again, now that I've got some more tools for evaluating claims?
I agree with gjm's advice, but also want to note that if that doesn't work, you might want to consider the theory that the situation in general is not about Christianity at all, but is a more social/psychological issue. Taking a stand on a controversial issue is risky, high status behavior, and most of us have both instinct and socialization pressuring us not to do it, so it's not really surprising that you're having a bit of extra resistance to the idea - if you keep the option of reevaluating the issue open, you'll experience less dissonance and be more ...
I've noticed during my thoughts on the issue that I seem to be biased against Christianity- although raised in a Christian household, I have noticed that I become more tense when reading effective arguments for Christianity and more relaxed when reading good arguments against it- I also feel strongly tempted to pull out books which I know give good arguments against Christianity.
I thought the issue of whether Christianity was actually true concluded- but given that I am now aware I'm biased, it's difficult to be sure. On the one hand, there is a lot of evidence against it (biblical contradictions etc...). On the other, there are some pieces of evidence that appear false 'on the surface' but which seem plausible when I take my bias into account.
