Structured as forty daily readings, The Purpose-Driven Life argues that modern anxiety and drift come from chasing self-defined goals instead of the purposes Rick Warren believes God assigns to every person: worship, fellowship, discipleship, ministry, and evangelism. Each chapter pairs scripture with a practical reflection meant to be worked through slowly rather than read straight through.
One of the best-selling nonfiction books of all time, it became a touchstone of the early-2000s evangelical small-group movement, spawning church-wide "40 Days of Purpose" campaigns built around its structure.
