In this six-session study, award-winning author Philip Yancey probes the very heartbeat—the most fundamental, challenging, perplexing, and deeply rewarding aspect—of our relationship with God: prayer. What is prayer? How does it work? And more importantly, does it work? In theory, prayer is the essential human act, a priceless point of contact between us and the God of the universe. In practice, prayer is often frustrating, confusing, and fraught with mystery. Prayer: Does It Make Any Difference? is an exploration of the mysterious intersection where God and humans meet and relate. Designed for use with the video.
