In Constant Prayer explains why is it important to pray like the early Christians did and what it means to pray without ceasing? Robert Benson and Phyllis Tickle discover the ancient practice of fixed-hour prayer and tell that if we structure this into our lives, we can live in God's continuous presence and reality.

Millions of lives have been transformed all over the world through disciple and praying at fixed times during the day and night. This book also teaches what the apostle Paul meant when he encouraged the Thessalonian church to 'pray without ceasing, for this is the will of God in Christ Jesus for you.'
