This book traces the origins of the upsurge of healing ministries, then takes each of the main arguments used by healers in support of their methods, and shows how each is mistaken. Important facts are provided about demonology, showing just what demons can and cannot do. It is then proved from Scripture that the sign-gifts have ceased. A chapter describes how James 5 should be implemented in churches today. Two important chapters present the biblical commands that the conscious mind should always be alert and rational for all worship and spiritual service. Included is an assessment of miraculous healing by a leading British doctor who was for many years a professor at Leeds University Medical School, the late Professor Verna Wright. This book has been translated into a number of languages including Chinese and Russian.
