Thanks for this post, Hyiwot.
Your contrast between Proverbs and Hosea is engaging, though I wonder how your description of Wisdom and Prophets might have been different had you compared Job and Second Isaiah. Not all of the prophets lob condemnation and not all of the wisdom books are quite as optimistic as Proverbs.
Proverbs *does* talk about God but in a different way than the prophets. Perhaps it's more accurate to say that Proverbs sees God's will as expressed in the structure of God's creation.
