Nothing wrong with picking and choosing one's beliefs, that's what free thought is all about. I would imagine that even most practicing mainstream Christians do not necessarily believe absolutely everything in the Bible word for word. Only *fundamentalists* do that and, despite all the publicity they get, they are a minority.
.........and it doesn't follow that once chosen that's what you have to stick with.
Please feel free to revise your position and choose different passages that completely contradict your previous held convictions whenever the need arises !
