The modern translations were taken directly from the oldest of these manuscripts, so the one thing you can be sure of is of any old work the Bible is the most accurate. Let's face it you problem with the Bible is that you don't like what it says. Wars have been fought over it. Many leaders have tried to destroy it, outlawed it, punished people for reading it. Yet it is still the best selling book ever.
People are willing to give their life up before renouncing it.
Speaking of which. You don't even have to read the Bible to know something special happened 2,000 years ago. The Romans were very good historians. Without the Bible you can still prove that Jesus lived, that He taught what is in the Bible, that He had followers. That He was put to death and when He was, His followers ran and hid.
