Job wasn't ready. You know when God starts a conversation by telling you to dress like a man that it is going to be good. God essentially says to Job, alright mate, put your big boy pants on, and pay attention. And then the questions begin, and they are God's questions exposing Job's limitations when compared to God's lack of those very same limitations.
Elihu strikes me a little bit like a young man who stumbles into Calvinism for the first time. Extremely passionate, very vocal, long-winded, lacking nuance, and rapidly running out of friends to yell at.
Job's search for wisdom leads him to the end of his own rope, which he finds in the dirt at the feet of his Lord. Wisdom is seeing God as more, not as less. Wisdom is worship of a big God, not manipulation of a small one. Wisdom is more obedience, more awe, more wonder, more faith, more trust, more worship, more of God, and altogether less of us. That's true wisdom.
