If you can imagine the story of the world as a giant movie, to not have some understanding of the Bible - its story, its history, and its impact - would be like watching a great movie and removing part of the plot. It can't be done. The real truth is that everyone regardless of faith tradition benefits from knowing and understanding these aspects of the Bible. It enhances one's knowledge of literature, science, art etc. It's difficult to read any classic work of literature for instance and not see biblical allusions.
