I confess to having no interest in the view there is a god who hovered over the Bible’s authors and told them what to write. Anyone who has looked into it knows there were arguments as to which written works of the time were to be included in the Bible. That evidence by itself points to a human-inspired work.
One could argue, I suppose, the authors of the Bible were men who did not need God because they had some unique understanding or insight into the divine. I don’t know how one could say we know that, or, how we could test for that theory. That line of thinking leads to a dead end.
The most basic of all Biblical questions is not what the Bible says but why it was written. If we know why it was written we can better understand what it tells us. So many devout Christians seem afraid to leave behind, even for a moment, their theory that their god directed the Bible and even discuss why idea humans wrote it.
Retired Episcopal Bishop John Shelby Spong writes and speaks about why the Bible was written. It was written, he says, because one group of people wanted to dictate the behavior of another group. Good behavior is rewarded with heaven and bad with hell. There can be no doubt those who wrote the Bible were rich. It would not be surprising if the rich wanted impose their views on those who were not rich.
That is why the Bible was written.
