Job 37 is the conclusion of Elihu’s speech. A storm is blowing in and Elihu speaks of God’s power. He concludes that we cannot comprehend God or His workings. We cannot find God because of His greatness. God disregards those who are wise in their conceit, which Elihu believes is the case for Job.
In Job 38 God speaks. He asks Job a series of questions. They deal with the workings of the universe. God is asking Job if he has had a part in the establishment and control of all things. These, of course are rhetorical questions since the answer is obviously “No.” God is the one who is in control.
Psalm 88 could have been written by Job. It is the prayer of one who is suffering. The writer is crying out to God for help.
