The book of Psalms is Israel's inspired hymnbook and prayer book, a timeless collection that explores the heights and depths of the human relationship with God. Structured in five books that mirror the Pentateuch, it contains a rich variety of literary types: hymns of praise, laments of personal and national sorrow, songs of thanksgiving, royal psalms celebrating the king, and wisdom psalms reflecting on the life of faith. More than any other book, Psalms gives us the language for honest prayer, inviting us to bring our full selves before God—our questions, our pain, our joy, and our worship. Through it all, the collection consistently directs the reader's gaze back to the steadfast love, righteousness, and ultimate sovereignty of the Lord, who alone is our refuge and strength.
