This is the most diverse section in the Old Testament in terms of types of literature. We learn a lot from these books about how the people of Israel lived as they related to God and one another. The Psalms represent the best prayers, hymns and calls to worship that Israel produced. Psalms teaches us what true worship is. Job teaches us how to struggle with doubt, pain and suffering, and even with our faith. The message of Job is that we should trust the providence of God. The message of the book of Proverbs is how to develop wisdom.
