Why God Seeks Your Joy

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.

Desiring God is a seminal work by John Piper that challenges traditional views on the Christian life. Piper argues that God is most glorified in us when we are most satisfied in Him, and that the pursuit of joy and pleasure in God is not only permissible but essential. The book delves into various aspects of Christian living, including conversion, worship, love, Scripture, prayer, money, marriage, missions, and suffering, all through the lens of Christian hedonism. Piper draws heavily from Scripture and the writings of historical figures like Blaise Pascal, Jonathan Edwards, and C.S. Lewis to support his thesis that true and lasting joy can only be found in God.
