How much can one man do to influence the world for Christ? How do we begin to measure the worth of his work? In this documentary, evangelism scholar Lewis Drummond examines the Billy Graham ministry phenomenon of the last half of the 20th Century-spiritually, culturally, and historically. As a personal friend and student of the Graham family, Drummond has compiled a book that is a great resource for any student, pastor, or layperson seeking a better understanding of the Graham ministry.
