In truth, there is only danger in rejecting the Bible if the Bible has value that cannot be found elsewhere. Many who reject the bible go on to embrace non-Biblical faiths. Do you mean to say that non-Biblical faiths have less value than Biblical faiths and are, as you put it, "truth of our own devices" "with no foundation other than ego"? I don't think it is whatyou mean to say, but i see little room for your words here to mean anything else. A good tree cannot give forth corrupt fruit. What are the fruits of the Bible, if not its believers?
