Personally, because a thorough understanding of the Bible shows that its teaching is quite different to what is often portrayed in media and in the assumptions of people like myself who had not previously read it. You can take many individual parts of the Bible out of context and make it sound like madness but reading the whole in its entirety has a narrative that many miss. For those raised on the internet and faster gratification (like me), try The Jesus Storybook Bible which I personally think is a great effort at paraphrasing the original. EDIT: clarity
