Clive Staples Lewis (29 November 1898 – 22 November 1963) was a British writer and lay theologian. He held academic positions in English literature at both Oxford University (Magdalen College, 1925–1954) and Cambridge University (Magdalene College, 1954–1963). He is best known for his works of fiction, especially The Screwtape Letters, The Chronicles of Narnia, and The Space Trilogy, and for his non-fiction Christian apologetics, such as Mere Christianity, Miracles, and The Problem of Pain.
Lewis and fellow novelist J. R. R. Tolkien were close friends. They both served on the English faculty at Oxford University, and were active in the informal Oxford literary group known as the Inklings. According to Lewis's memoir Surprised by Joy, he was baptized in the Church of Ireland, but fell away from his faith during adolescence. Lewis returned to Anglicanism at the age of 32, owing to the influence of Tolkien and other friends, and he became an "ordinary layman of the Church of England". Lewis's faith profoundly affected his work, and his wartime radio broadcasts on the subject of Christianity brought him wide acclaim.
Lewis wrote more than 30 books which have been translated into more than 30 languages and have sold millions of copies. The books that make up The Chronicles of Narnia have sold the most and have been popularized on stage, TV, radio, and cinema. His philosophical writings are widely cited by Christian apologists from many denominations.
In 1956, Lewis married American writer Joy Davidman; she died of cancer four years later at the age of 45. Lewis died on 22 November 1963 from renal failure, one week before his 65th birthday. In 2013, on the 50th anniversary of his death, Lewis was honoured with a memorial in Poets' Corner in Westminster Abbey.
The Screwtape Letters is a great book for thinking about how we have to choose between good and evil. C.S. Lewis inked two devils into a story about trying to lead a man down the wrong path. Uncle Screwtape is teaching a younger devil named Wormwood how to lead the human down the wrong path.
I've included an audio-play, the actors give the book life and I highly recommend it. It follows the book word for word.
Mere Christianity is a great book for anyone that wants look at the Christian faith from the eye's of a great writer that does an outstanding job of explaining the Christian faith to all people. I particularly liked book four "Beyond Personality" which is at the end of the linked audio book below. I hope you enjoy Mere Christianity as much as I did.
