The whole notion that Bronze Age prophets had a "truth" revealed to them is only superstition without the metaphoric element.  The Bible is a product of an ancient oral tradition and simply cannot be approached with the modernist, scientific notion of "truth" evangelicals layer on to it.  To do so is to confuse poetry with "fact".  A world that loses poetry will surely be poorer for it, and faith is something of a poetic idea.  When Pastor X tells us that, for instance, the great flood was an historical event -- and many do say exactly that -- because The Bible says so, Pastor X is telling us that he doesn't understand The Bible.  I guess that sounds pretty harsh, but all it really means is that Pastor X is a modernist missing the nature of oral tradition.   Try Ong's book "Orality and Literacy."  (Ong, BTW, was a Jesuit scholar.)
