Uh, Timebuilder, with all due respect, I don't think comparing the Bible to a POH is valid. My POH was written in English, and if necessary I can find the guy who wrote it, tap him on the shoulder, and ask "hey, what'd you mean by this?" It's not easy to do that with the Bible.
I concede that God might exist, but I can't agree with you about the Bible. It is, in essence, a book of parables, fables, and memoirs. It's a an important piece of literature, but it's no more divine than Jonathan Livingston Seagull. (Which is a pretty good book about religion, by the way.) I know the Bible says it's the word of God. I can also tell you I'm really John Travolta. That doesn't make it true.
Someone suggested that you can tell it's the word of God because of the way it cuts into people's souls when they read it. But that doesn't happen to everybody. Are those who are unmoved by the Bible contaminated or "cursed" in some way? Is the "word of God" so feeble that it can't break through that contamination?
