Mere Christianity (1952)
Clive Staples Lewis was a British writer and lay theologian. He held academic positions in English literature at both Oxford University and Cambridge University . 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 baptised 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 popularised 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 kidney 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. Wikipedia

“But what of the poor Ghosts who never get into the omnibus at all?”
Clive Staples Lewis book The Great Divorce
'Everyone who wishes it does. Never fear. There are only two kinds of people in the end: those who say to God, "Thy will be done," and those to whom God says, in the end, "Thy will be done." All that are in Hell, choose it. Without that self-choice there could be no Hell. No soul that seriously and constantly desires joy will ever miss it. Those who seek find. To those who knock it is opened.'
Ch. 9, p. 72; part of this has also been rendered in a variant form, and quoted as:
There are two kinds of people: those who say to God, "Thy will be done," and those to whom God says, "All right, then, have it your way."
