E.A. Johnston, Ph.D., D.B.S. is a fellow of the Stephen Olford Center for Biblical Preaching and an evangelist and conference speaker with Ambassadors For Christ Intl.-USA. Dr. Johnston has been a student of revival for several decades and his ministry passion is toward revival in the Church and spiritual awakening in the world. Dr. Johnston is the author of seventeen books. The last three books of Dr. Johnston, published by Revival Literature, are George Whitefield: a Definitive Biography in two volumes, clothbound with dust jacket, containing 1172 pages and 48 photos. The foreword and preface were written by Dr. J.I. Packer and Richard Owen Roberts; God's "Hitchhike" Evangelist: The Biography of Rolfe Barnard with a new look at one of the nation's unique evangelists in the 20th Century that will prove to be captivating reading for those interested in revival; and Asahel Nettleton: Revival Preacher, a clothbound book of 519 pages, also commended by Dr. J.I. Packer who says: "The momentous ministry of the Edwardsean evangelist Asahel Nettleton, a key figure in the Second Great Awakening, has been effectively forgotten during the past century and a half of less-than-Reformed revivalism. Dr. Johnston's masterful and thorough biography is a long-overdue tribute to this outstanding servant of God, and is priority reading for all who care about evangelism today."
