"40 Days of Purpose" is a spiritual growth campaign based on the book "The Purpose Driven Life" by Rick Warren. It encourages participants to explore their life’s purpose through daily readings, reflections, and activities over a 40-day period. The program is often conducted in churches and small groups, fostering community and discussion. The campaign focuses on five key purposes: worship, ministry, evangelism, fellowship, and discipleship. Each week emphasizes a different purpose, helping individuals understand their role in the world and their relationship with God. Participants are encouraged to apply these principles in their daily lives for personal transformation.
