Quite a discussion going here....on the very topic I am interested in and searching for clarity. Here is a link I came across to the "genius of ambiguity" argument (Van Kleeck), as well as a link to the Strouse article. Strouse makes an excellent case for verse 7 teaching the preservation of Scripture. I really like Strouse. Where can I find more of his teachings?

Yet Van Kleeck makes a point worthy of consideration.
