John Wesley led one of the greatest Christian revivals in the history of England. The ‘Forty-Four Sermons’ which he compiled for use by Methodist preachers remains a timeless classic and a definitive collection of the core Wesleyan doctrine. ‘Awake Thou Who Sleepest!’ is the third message from the 'Forty-Four Sermons'. It was originally preached by Charles Wesley, on Sunday April 4, 1742, to the congregants at Christ Church, University of Oxford. The sermon was based on Ephesians 5:14; "Awake, O sleeper, rise up from the dead, and Christ will give you light. "In this sermon, Wesley discusses the identity of the 'sleepers' referred to in scripture, challenges his hearers to wake up to Christ, and explains the great reward of those to whom Christ gives light.
