Tim it is hard to get away from the thinking that the bible is the only place for morality. I think what really helps me is that what has pushed most modern countries forward was not the bible, it is secular writers. If we only looked to the bible then I could own a slave! How is that for moral? Not to mention its position on women and gays.
Overall there are many different places you can look to for a spiritual message.
So unless you want to own a slave, opress some women, and judge all fornicators, it might be healthier to find a new book.
