Jews preserved it as no other manuscript has ever been preserved. With their massora, they kept tabs on every letter, syllable, word and paragraph. They had special classes of men within their culture whose sole duty was to preserve and transmit these documents with practically perfect fidelity–scribes, lawyers, and massorettes.
In regard to the New Testament, there are about 13,000 manuscripts, complete and incomplete, in Greek and other languages that have survived from antiquity.
A thousand times over, the death knell of the Bible has been sounded, the funeral procession formed, the inscription cut on the tombstone, and committal read. But somehow the corpse never stays put.
No other book has been so chopped, knifed, sifted, scrutinized, and vilified. What book on philosophy, religion, psychology, or belles lettres of classical or modern times has been subject to such a mass attack as the Bible? With such venom and skepticism? With such thoroughness and erudition? Upon every chapter, line and tenet?
The Bible is still loved by millions, read by millions, and studied by millions.
