The Psalms, a collection of 150 poems and songs, serve as a spiritual "playlist" guiding the Israelites in worship, prayer, and understanding God's redemptive story. Psalm 1 introduces the concept of the good life, describing it as a life of joy, contentment, and blessing derived from a right relationship with God, meditating on His word, and avoiding the company of the wicked, ultimately highlighting that true fulfillment comes from living according to God's ways.
