You live in a society that is shaped in every possible way by the Bible. The language you use, the laws you obey (and disobey), the founding principles of your nation, the disputes about abortion, homosexuality, adultery - these and so much else in your world are rooted in the Bible. You don't have to read it for its truth value. You should read it to understand how your world got the way it is, the way you would read the constitution or Shakespeare.
