While I can't say I agree on ALL points, I agree with Mark that a lot of the doctrine was adapted from Greco-Roman mythology, of shades in the underworld, tortured for eternity. I agree with him and Rob Bell that I don't buy the idea that lots of humanity will be (or are) tortured for centuries or forever. I don't see that squaring the the Bible, and I don't see that squaring with God's M.O. There was a quote, attributed to Mark Twain, where he supposedly didn't agree with it, either. It's one thing to destroy a villain, it is another to punish for a time during his sentence, but to torture forever made no sense to him. (I just don't see "eternal torture for humanity" working on paper.)
