A Christian Atheist?

In 'Mere Christianity', C.S. Lewis argues for the existence of God and defends Christian theology. The book is divided into four parts: the first argues for the existence of God based on the 'law of human nature'; the second defends Christian theology, including the 'Liar, lunatic, or Lord' trilemma regarding Jesus Christ; the third explores Christian ethics, including the cardinal and theological virtues; and the fourth discusses the Christian conception of God, particularly the Holy Trinity. Lewis also addresses topics such as free will, morality, sexual ethics, and the institution of marriage. The book is known for its clear and logical presentation of Christian apologetics and has been praised for its straightforward and humorous writing style.

The Screwtape Letters is a Christian apologetic novel written in a satirical, epistolary style. It consists of 31 letters from Screwtape, a highly placed assistant to 'Our Father Below' (the Devil), to his nephew Wormwood, a novice demon tasked with securing the damnation of an ordinary young man. The letters provide advice on various methods of undermining God's influence and promoting abandonment of God, while offering insights into human nature and the Bible. The book is a profound and striking narrative on spiritual warfare and the power of the devil, highlighting the subtle forms of sin such as vanity, pride, and distraction that can lead humans away from God.
