What I think is also significant is that the Books of the Hebrew Bible cover about 4,000 years, though written over a one-thousand-year span. Whereas the New Testament covers less than a hundred years, unless of course you consider what the New Testament says about the End. It took, I am guessing, between 40 and 50 years to write. I do not know how accurate my numbers are, but I think you get the idea.
Perhaps one way that the New Testament beats out the Old Testament is that the New has more Books written during that 40+ year span than any 40 year span in the Old, although the Old has more written in a 40 year span, but it was written in only five books (the wilderness wanderings when Moses wrote Genesis through Deuteronomy).
I am just having fun here.
To me the length of the biblical Books shows just how little God included in His written word, because He could have had so much written that it would have overwhelmed us. Therefore, what little He did reveal has to be highly significant for the human race.
Now let us bury our noses in His Book, and see what we learn.
