Romans 8:7 The mind governed by the flesh is hostile to God; it does not submit to God’s law, nor can it do so.
Hostility means Job's enemy.
1 Corinthians 11:8 For man did not come from woman, but woman from man;
Job's points good and bad. We can also see the humility of Job and the most humiliate person is Jesus Christ.
We can see that Job is hopeless of the circumstances he had, but be reminded that God is our only hope. Also Job wants to die but he still have little faith remains.
Jesus alone brought life in us.
