The author of II Timothy--who at least purports to be the apostle Paul (although some scholars believe that it was, instead, a close associate of his)--declares, in 3:16, that all scripture is theopneustos--literally, "God-breathed."
There is probably no need, now, to get into the matter of just what "scripture" he was referring to. (Since there was then no canon of the "New Testament," he was, presumably, referring to the "Old Testament." But it could be applied equally to both.)
Some view this as a confirmation of the so-called "Dictation Theory" of inspiration: i.e. that God dictated the words, verbatim; and that the writers simply took them down, word-for-word, like good stenographers.
The problem with this, it seems to me, is that it begs the question: Why does God use one style when He is writing through Paul, and an entirely different style when He is writing through Peter? Or one style when He is using Mark, and an entirely different style when He is using John?
This is why I tend toward thought inspiration instead.
