For me, the most pronounced contrast between the prophets and the Prophetic literature and Wisdom literature lie in the imparting of divine truth and the weight assigned to that through the narratives. Let's start with the prophets.
Prophetic figures are informed in a tradition that held that an oracle or prophet was regarded to be of God, "inspired by the will of God", and a mediator between man and God. The irony of this is that they are usually at the service of the King, at least in the Assyrian tradition. And because kings rarely allowed for the possibility of information counter to them, their prophetic slant was as Collins’ book suggests, “being at the self-interest of the king” and focused on “ the affairs of the king.”(page 197) The messages often “ provide assurance of divine support in time or crisis”—as in crushing a rebellion or defeating an opponent. And while this was not always the case, especially in regards to some of those mentioned in the Bible, it does call into question some of the authenticity of their messages. One such Prophet mentioned in the Bible who stands as an example would be Isaiah. He did indeed work in close relationship with the monarchy and the temple. Others like Amos and Jeremiah did not follow the expected order and spoke out against wrong, suggesting perhaps they were indeed speaking the voice of the Divine.
Wisdom literature on the other hand in informed by a Gospel of unshakeble faith in God. Moving the focus from being an agent worker, a vassel of the Divine to being a pillar of God, one who props up a belief in God and the fruits of standing on that foundation. Collins rights says wisdom characters differ from the prophets in “emphasizing the priority of understanding over action.” Suggesting that action (as with the prophets) can be corrupted or spoiled by sin. For me, the best example of this is the story of Job. A great quote that captures Job’s stand in the midst of all of his struggles was also given by Collin. He writes of wisdom literature saying, “One can arrive at knowledge of the Creator by studying the order of the universe. That study over a lifetime is what Job stood on and what feed his unshakeable commitment and belief in the goodness of God even when things were very bad.
