The Atheist Who Followed the Clues Home

In 1941, as German bombs fell on London, a former atheist sat before a BBC microphone at Broadcasting House and made a startling argument. C.S. Lewis, a medieval literature scholar at Magdalen College, Oxford, had been invited by James Welch, the BBC's Director of Religious Broadcasting, to explain Christianity to a war-weary nation. Lewis didn't begin with scripture or church doctrine. He began with something every listener already knew — the stubborn human sense of right and wrong.

Across four series of radio talks broadcast between 1941 and 1944, later published as Mere Christianity in 1952, Lewis argued that this universal moral law was itself a clue. Every culture, he observed, recognized fairness, courage, and honesty as virtues — not because they had agreed to, but because something real stood behind those convictions. The Moral Law, Lewis reasoned, pointed beyond nature to a Lawgiver.

What made his argument so compelling was its starting point: not faith, but honest observation. He asked listeners to look carefully at what they already knew to be true.

The Apostle Paul made a remarkably similar claim in Romans 1:20 — that God's invisible qualities have been "clearly seen, being understood from what has been made." Creation itself is a signpost. The sense of justice that stirs in every human heart, the beauty that catches our breath, the reason that reaches beyond the material — all of it points somewhere. Lewis simply had the courage to follow where the clues led. The question for each of us is whether we will do the same.
