Obviously there are minor errors in the New Testament manuscripts, since many of the very old ones differ from one another in wording somewhat. However, by comparing ancient copies of the various New Testament books to each other, we can, by a logical process of elimination, figure out the original wording to about an estimated 99 percent certainty. That's fairly good, so I wouldn't be too concerned about it.
Likewise, there appear to be minor scribal errors in the Old Testament, but the Jews went to extraordinary lengths to insure accuracy, and of course we have very old copies (like the Dead Sea Scrolls) that we can compare modern versions to, so any errors are probably too slight to make any real differences in meaning of the text.
There also seem to be some minor translational errors in the King James Version of the Bible, based on our more complete understanding of Ancient Hebrew and Konie Greek, but these errors seem to be insiginificant.
I don't think that it makes logical sense to assume that the Bible contains any major errors in God's message. First of all, if God, who is all knowing & all powerful, were trying to give us his message, and he was going to judge us for how well we followed it or not, then it would be cruel & unfair for God to give us a confusing book full of mistakes.
Second of all, if the Bible writers were mistaken about what God wanted, then how would we know, unless God spoke to you directly also? And if he did, then how do we know that you didn't make the same mistake that all of the other prophets did? After all, you are just as human as the other prophets were, you know.
I think that it makes more logical sense to assume that God, who was all knowing & all powerful, picked just the right people to convey his message to us, so that any possible errors are negligible and don't affect the message. If the Bible has errors, then it is useless as a guide to living, and one might as well chuck religion in to the trash can and just do his own thing, if God is too incompetent to figure out how to get his message to us right.
