This book suggests that God's power is waiting to be unleashed through the Holy Spirit, resulting in effective evangelism and a new depth and commitment among individual Christians. The author attempts to provide a perspective on the biblical accounts of the supernatural and their application today. It includes stories which demonstrate the relationship between power evangelism and church growth, a chapter on revival and a study guide which offers the reader a ten-week group study with pratical emphasis on daily readings, discussion questions and a "clinic" session in which readers put into action some of the aspects that have been studied. Previous books by this author include "Power Evangelism", "Power Healing", "Practical Healing" and "The Dynamics of Spiritual Growth".
