There are many books about prayer, but the best book we have on prayer is the Word Himself. In "The Heart of Prayer," Jerram Barrs takes a closer look at Jesus' practice and teaching about prayer. He shows how Jesus prayed during times of temptation, struggle and ministry, and how these times of prayer sustained and comforted Him to accomplish His purposes. You'll be encouraged to continue in prayer, keeping your eyes on Him, rather than your own efforts.
