I started this thread and now I have some more wood to throw on the fire. I went to a link that had many quotes from JW publications, some of which now they have gotten "new light" and changed and some that they still believe. But anyway there was a quote from The Watchtower on 4/1/1920 where the WT says " That it contains some mistakes if freely admitted. Even the Bible contains some." Now exactly what the "it" is in the first sentence I don't know, but the second one is clearly saying that they admitted then that the bible contains some mistakes.
Another quote from WT 4/15/1928 says," Sometimes a member of a class will refuse to engage in the canvassing for books because there are some mistakes in the books, and says his conscience will not permit him to put books in which there are mistakes into the hands of the people. Of course this is another method that the enemy adopts to confuse the minds and furnish an excuse for not being faithful to the Lord. As every one knows, there are mistakes in the Bible and there has never been a book written yet that is perfect that has been written by any human hand.
So my thoughts are since God is perfect wouldn't he make sure that his words are perfect to us. Or maybe I'm just looking at it wrong. But since it's always said God never changes, why would he inspire something one year and come back and change it a couple of years later. Such as the JW's saying they get their info from God and then when they get caught in one of their "man-made" interpretations of something they say Jehovah gave them new light.
