R. A. Torrey excelled as an evangelist, pastor, author and educator. Few people have been as successful as Torrey in four very different areas of ministry. Torrey was a student at Yale when he heard Moody speak for the first time. Moody's sermon "Faith Can Do Anything" became the theme of Torrey's ministry. Torrey wrote a total of more than forty books, including "Why God Used D. L. Moody."
