As far as I understand the question, I tend to think Willimac is on to something.... Paul had his favorite catch phrases that he used... "God forbid!" For example. "All things are lawful unto me, but not all things are expedient". He said it at least 2 or 3 times in slightly different ways. I can't think of examples, but I've noticed the same thing with Isaiah and Jeremiah... That is certain writing styles and phrases they like to use.
So the question might be, "do we look at every word they wrote and take them all to heart or do we look at the overall jist of the message they were getting at"? I believe the former. Of course, we look at the overall message (for example, don't get hung up on the revelation that might be in one verse without reading the whole chapter). But I do believe that every word that the prophets wrote in the NT as well as the Apostles and servants in the NT must be considered, despite the author's style of writing.
Why? First off, Jesus said man shall not live by bread alone but by every word of God. He also said not one jot nor tittle would fail to come to pass. So why? Jesus said so! But also, God called these men knowing their style of speech and favorite phrases. I have to think he took that into account when he called them.
So God called these men to write the Bible, and he knew how it would come out even before he called Moses to start the work. And the work came out perfect!
