The Holy Spirit Doesn't Guarantee the Aptitude of a Biblical Author

Just like jesus's parables, are god's word and they convey truth. Parabolic material conveys truths because it's god's word. And i can cite that truth in port of the point i need to make, which they can't. There 's then a question ofwll what degree of awareness does a biblical author have of the nature of the text he is reading? He may assume that it's historical when it's not. Or he may assume it's not historical when it is. But i divine inspiration doesn't guarantee the assumptions that a biblical author is making.
