There is a resurgence of interest in how evangelicalism–today’s version–began. What are its roots? How did it emerge and grow? Several individuals played key roles in the growth of this “new” evangelicalism. One of the central leaders was Boston’s Harold John Ockenga, pastor of the historic Park Street Congregational Church. Ockenga also helped found Fuller Theological Seminary, Gordon-Conwell Theological Seminary, the National Association of Evangelicals, and Christianity Today. Garth Rosell’s The Surprising Work of God: Harold John Ockenga, Billy Graham and the rebirth of Evangelicalism examines the birth and development of modern American evangelicalism–its history, personalities, and institutions. The history of that time is seen through the window of the life, ministry, and writings of Ockenga and his long friendship with Billy Graham. This book will be of value to anyone with an interest in the American Christianity of the last century. Rosell utilized the records of the National Association of Evangelicals (SC-113) for this publication.
