Thanks for your post, Caroline.
Your description of the relative closeness of God in these books was interesting. It feels the opposite to me. I find the style of books like Proverbs as cold and distant; here, God isn't a character or particularly involved with people but instead God is only known through our own conclusions about how the world works. The God I find in the prophets is really passionate--loving, angry, the whole range. God cares about how people treat each other (Amos, Micah) as well as about how they worship. Cares enough to get angry.
Your description makes Job's faith sound rock solid. How did you interpret his lawsuit against God?
