Zophar emphasizes the vastness of God's knowledge and power, challenging the idea that humans can fully comprehend God. He encourages Job to turn away from iniquity and seek God, promising that doing so will bring security, hope, and rest. Zophar predicts that the wicked will fail and not escape their fate.
