Have you ever noticed in your history class or science class that your book said 10th edition or some other edition? Like the bible the historical facts and contents dont change. What does change however is style in which it written. Do you really believe that kids today read from the same history books their grandparents did? If you are seeking genuine answers to this question, you should go to biblegateway.com and to a comparison of what different translations of the bible says. You will see that even though style and the way in which things are said are change, the overall message and substance stay the same. If you dont trust the content there you could also go to a Barnes and Noble and compare a few different translations there. biblegateway.com will be easier though.
