There is one good reason to read a Bible: To find out what it really says, without religious bias. You read the Old Testament, and see for yourself how "loving" Jehovah really is. Then, when you are through puking, make your decision about whether this Almighty Lowlife Scumbag deserves your worship. You can also read the stock examples that were written in lieu of your getting anything. Are you satisfied that someone that was around 3,000 years ago got what he needed? Or, are you going to insist that, unless Jehovah satisfies you, IN THIS DAY AND TIME, he is not worth serving?
Another way you can benefit from a Bible is determining if the religion you are contemplating really abides by it, as it claims to. If they claim to abide by the Bible, and there are glaring discrepancies between its doctrine and the Bible, find out why. Ask questions. Do they insist that you believe the bad doctrine, and teach it, until they themselves fix it? If you are merely studying, insist that you abide by the Bible itself instead of the Washtowel doctrine--and see how far it gets you.
