Based on best-selling author Max Lucado’s first book on prayer, Before Amen (Thomas Nelson), more than 100,000 people have signed up to take the Before Amen prayer challenge, launched in September.

The challenge involves praying for four minutes every day for four weeks.

Thomas Nelson and FaithGateway.com host the event online.

Integrity Music also released a musical companion, Before Amen: A Worship Collection, featuring Michael W. Smith, Darlene Zschech, Paul Baloche, All Sons & Daughters, and Planetshakers.
