C. S. Lewis (1898–1963) was one of the twentieth century’s most influential Christian writers, scholars, and apologists. Born in Belfast and later teaching at Oxford and Cambridge, Lewis wrote widely on faith, literature, morality, suffering, and the Christian life.

After moving from atheism to Christianity, he became known for his ability to explain complex theological ideas with clarity, imagination, and reason. His best-known Christian works include Mere Christianity, The Problem of Pain, The Screwtape Letters, and The Four Loves. He is also beloved for The Chronicles of Narnia, a series rich with Christian themes of sacrifice, redemption, courage, and hope.

Lewis’s writing continues to appeal to both committed Christians and those exploring faith. His combination of intellectual depth, storytelling, humour, and spiritual insight has made his work enduringly influential, helping generations of readers think more deeply about God, humanity, and the claims of Christianity.
