Fordyce Detamore (1908-1980) is regarded as one of the most successful and well-known Adventist evangelists of his time. During his long association with the Voice of Prophecy Evangelism Association he preached in all the major cities of the United States and Canada as well as Hong Kong, Manila, Singapore, Indonesia, and Australia.

An innovator, Detamore was the first major evangelist to shorten campaigns to three or four weeks and to use Bible correspondence courses. He made a specialty of working with former church members, and rebaptized thousands of them in his 50 years of ministry. Noted for making hundreds of visits in homes and workplaces during each of his crusades, he shares in this volume the principles he used with outstanding success.
