There is growing interest in the story of mid-twentieth-century evangelicalism. One of the central leaders of that era was Harold John Ockenga. He was pastor of the historic Park Street Congregational Church in Boston and cofounder of Fuller Theological Seminary, Gordon-Conwell Theological Seminary, the National Association of Evangelicals, and Christianity Today. The Surprising Work of God 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 lively, engaging story will be of value to anyone with an interest in the American church of the last century.
