The Psalter teaches us about the life of faith, about honest dialogue between us and our Creator. The Psalter gives us hope that the life of faith is worth the effort, often by contrasting the righteous and the wicked. Themes from the Wisdom literature of the Bible (Proverbs, Job, Ecclesiastes, and Song of Solomon) are prominent in some psalms. (Examples: Psalms 37, 49 and 73)
People in whom God is acting to make them like Him are contrasted with
people who deny God and live like He doesn’t matter.
