Dr. J. Edwin Orr was a visiting professor when I was in seminary. He held doctorates from universities on three continents, including the D.Phil. from Oxford. He was a professor at Fuller Theological Seminary from 1966 to 1981 and continued to lecture around the world until his death in 1987. He devoted his life to documenting great spiritual awakenings in Christian history.
This video has a peculiar phenomenon in that Prof. Orr is wearing a red suit coat and is standing in front of a mostly red background. Despite this distraction, the video, which runs 26 minutes, is well worth viewing for anyone who cares what God has done and wants to do in revival.
