Why has God not answered my prayers? What should I be praying for? If everything I prayed for came true, would I be ready? In this spiritual classic, Eberhard Arnold mines the riches of biblical teaching on prayer and the example of Jesus, the Hebrew prophets, and the early Christians to point us back to the prayer that pleases God most - prayer that has the power to transform our lives and our world. In a new reflective response, much-loved author Richard J. Foster relates Arnold's words to our contemporary reality.
