The Case for Christianity is a compilation of Lewis' famed radio addresses during World War II. Lewis argues that a careful examination of our philosophical presuppositions will compel us to come to terms with the basics of Christian faith. He condenses his argument into two parts: "Right and wrong as a clue to the meaning of the universe" and "what Christians believe."
When we come to the realization that a real moral law exists, that there is a Power behind that law, and that we have broken that law--then Christianity be gins to speak to us. "The just shall live by faith" has real meaning to people who understand their desperate spiritual condition.
Lewis, who was a layman and who had been a non-Christian for many years, speaks with authority. He understands the difficulties that ordinary people feel about religion. His clear and compelling reason forces nonbelievers to reexamine their attitudes toward Christianity. For this reason Lewis's writings speak as persuasively today as they did in the 1940s. Their cogency still recommends them as the best missionary literature for secularists.
