God turns to Job's friends and tells them to offer a sacrifice for their sins with Job as their intercessor. Unlike Job who was looking at the facts of the world and desiring to come before God to speak, the friends were basing their words on a worldly philosophy. They took faith out of the relationship with God and focused on your works. But faith is about receiving God's own life through Christ, therefore we cannot focus on our works without understanding they must flow from God first. We should not focus on the works but on God first. Job had always been looking to God, so he can act as a priest here. He "saw" God in the whirlwind, is part of humanity, and conveys forgiveness to the friends with the blood of beasts. This makes Job a Christ figure, but Christ is God, he is man, and he forgives through his own blood.
