It is a massively serious mistake for the significance of the Bible to be thought or imagined to be due to its having been inspired by God in its writing in the distant past. Of course, we can assume that it was inspired by God in its writing, but so also are a great many other things, among them a kind glance in the direction of someone living on the street, a glance with actual eye-contact. But the danger of putting the weight of the "authority" (I don't like that word) of Scripture on what happened long ago is that it at least tends to diminish (if not destroy) the way Scripture functions. "All scripture is inspired by God and is useful for teaching, for reproof, for correction, and for training in righteousness, so that everyone who belongs to God may be proficient, equipped for every good work." Yep. But notice that this inspiration is all about the way the Scriptures have a future, how they are put to work, not how they are secured in some dusty past, not how they have nailed something down. Surely, "unchanging" is not a word that would often be found in the vocabulary of workers. So, maybe the doctrine of the inspiration of the Bible is best understood as a doctrine about the future, that when all the dust of bygone civilizations have cleared, the Bible will have been found to have been inspired.
