@opusdei1972,
Of course if one considers that the God concept is different for the Jews than it is for Christians (and so, as a consequence, is the concept of inspiration), the problem may be caused by the lens one applies to the concepts of deity and revelation.
For Christians like Jehovah's Witnesses, God is a literal deity, a "supreme being" not too different than other gods like Zeus, for instance. But for Jews, "God" is actually not the ancient concept of what a deity is. The same term is used, but this is for a lack of a more accurate label.
In Judaism, tradition claims that before any direct revelation from God, Abraham came to realize that deities were false. He came to this realization by comparing nature to the idol gods sold by his father. Abraham reasoned that the world was "caused" by something far different than the gods worshipped by people.
This ultimate "Cause" is the God of Abraham and the Jews. Exactly what this Cause is transcends human capacity to comprehend. Compared to this Cause, a human is like an amoeba under a microscope and God is like a human watching it. An amoeba has no ability to comprehend the human on the other end of the microscope, and if it could think any concept it did attempt to create to define the human would fail.
This is not to say that the Cause is a being with a mind either. Some Jews think this Cause may be the universe itself with the laws of nature that govern and caused it. Some think this Cause has intelligence but so far advanced that human logic and intelligence cannot compare. God, therefore, in Judaism is mystery.
I remember a line from the film "Indiana Jones and the Last Crusade" where Dr Jones is teaching his class and says: "Archeology deals in facts. If you want truth, take a philosophy class."
The attitude that the Bible is unacceptable if it lacks facts is an argument we used to use out in field service. As Jehovah's Witnesses we were taught that it was a book of facts and that our beliefs were "proven" by looking into this fact book. We wouldn't believe anything without such "evidence," and we surely wouldn't believe in the Bible if it wasn't factual.
But it's a collection of writings dealing with the search for truth. It doesn't deal in facts. The whole idea that it's worthless or uninspired by the great Cause of the universe because it's not the fact book the Watchtower told you it was is like running back to the JW attitude: "I'm not going to believe it if it's not a fact book!"
Religion is like philosophy, concerned not with the empirical evidence of science but what the existence of the evidence means, the WHY it is here in the first place and why YOU are witnessing it. Just because the Bible is not the book JWs told you it was doesn't make the Bible wrong. It makes the JWs wrong.
