Prayer. Does it make any difference? Is written by Philip Yancey (Zondervan, 2006) in his easy to understand conversational style.
Yancey explores many of the same questions we all have: Why pray? What should I pray for? How and when should I pray? What difference does it make? Why doesn’t God answer my prayers? Do my prayers actually change God’s mind? Yancy draws on his considerable experience with others to give poignant examples and illustrations for gaining insight into these and many other questions. This book is a candid discussion of prayer for anyone wishing to better understand and deepen their prayer life.
