I've caught up on this thread, and there was a point where it was brought back to a matter of belief. ik9000 talked about evidence. These seem to be contradictory, but....
to repeat something I've said before, on many threads, as Christians we do not follow a book. We follow Christ. (Of course, like ik9000, and others here, I believe the Bible to be correct, accurate, relevant and without error.)
The point is, no matter how many times someone wishes to denigrate the text itself, the fundamental evidence is in the HERE AND NOW. The very real evidence of Christ's impact on MY life, *now*. Yes, I know someone will now jump on the bandwagon of subjectivity, claiming that I'm hearing little voices, am deluded, hallucinating etc, but that is as useful, in this case, as claiming (eg) love is bogus, since they've never experienced it. They can't see love, hear it, taste it, prove it/disprove it other than claim it is all down to chemical reactions. So they throw it out as fiction.
When you accept Christ's absolutely tangible love, in your own life, and experience the release from guilt, from death, etc, you cross over the divide. No, not some brainwashing, sorry.
So, yes, it happens on a personal level, but that is the case for all relationships. The point is that THAT is the difference - we do not hold to an ancient text out of wishful thinking; it is based on what is happening in our lives NOW.
