In the Bible we routinely have the recorded words of particular individuals. In purely narrative accounts, most generally understand that not every word spoken by every character is intended as divine instruction in what to believe and how to act. Some characters serve more as bad examples than good, in word and deed.
On the other hand, we encounter other portions of scripture which are seemingly direct instructions, admonitions, and predictions right from the mouth of a human author. These passage don't recount events and their associated conversations. Unlike the passages of the narrative type, these words are almost universally taken as divine in origin. Whereas Bible characters in various stories maybe expressing purely personal thoughts and ideas, when the book's author speaks personally, that is assumed to be the very words of God transmitted by the human ghostwriter.
Interestingly, the Apostle Paul states categorically that some of what he wrote was personal opinion and not God inspired (I Corinthians 7:12). That admission flies in the face of what is generally assumed above about the words emanating directly from Bible writers. If Paul occasionally injected personal, uninspired thoughts and ideas, how do we know that didn't happen with other writers? Why do we believe that even Paul always pointed out when he spoke separate from divine revelation?
Considering the possibility that the Bible contains a mixture of merely human religious understanding and actual divine wisdom certainly makes it easier to reconcile. Such a conclusion would destroy the Bible as the necessary divine instruction book. That might seem a little scary, not having a roadmap to heaven; but then why did we ever need 2000 pages of text in order to experience what God desires in the first place. He is able and doesn't need any map.
