A partial biography of Billy Graham and an account of the evangelistic crusades with appended sermons. Illustrations include photos of Graham, his family, John Foster Dulles, crusade sites. Five of Billy Graham's addresses are included. Purpose of the book, published in 1954, was to explain what might be bringing about Graham's phenomenal audiences at evangelistic crusades shortly after their beginning. Robert Van Kampen, the owner of Van Kampen Press, had a life-long friendship and working relationship with Graham, beginning in the late 1940s. He was very active in the Billy Graham Evangelistic Association.
