Considering the enormous number of ancient New Testament manuscripts, there are only nominal differences in the various copies. The data for the New Testament is impressive. Only 40 lines, or one fifth of one per cent are in question. This compares to large textual variances in other ancient writings. Further support for the Bible comes from the fact that events of the New Testament are supported by writings outside the Bible.
Corroboration is available from several secular and Jewish historians of antiquity.
Even if all the New Testament manuscripts disappeared, it would still be possible to reconstruct almost the entire New Testament with quotes from the Church Fathers. Both the authenticity and the general integrity of the books of the New Testament may be regarded as finally established. In addition to its being externally verified, significant further evidence of its reliability is the internally consistent nature of the Bible. It is truly an amazingly consistent document. The messages of approximately 40 different writers of the 66 books of the Bible, written over 1,500 years, in three different languages, all fit together like the pieces of a giant jigsaw puzzle.
