A milestone in the history of popular theology, -The Screwtape Letters- is an iconic classic on spiritual warfare and the power of the devil.This profound and striking narrative takes the form of a series of letters from Screwtape, a devil high in the Infernal Civil Service, to his nephew Wormwood, a junior colleague engaged in his first mission on earth trying to secure the damnation of a young man who has just become a Christian. Although the young man initially looks to be a willing victim, he changes his ways and is -lost- to the young devil.Dedicated to Lewis-s friend and colleague J.R.R. Tolkien, -The Screwtape Letters- is a timeless classic on spiritual conflict and the invisible realities which are part of our religious experience.
