All this is startling for a couple reasons. First, Lewis only had twelve years left to live when he had this 1951 experience. He had written most of his books. But it was at this point that the forgiveness of the gospel truly clicked into place for him. Second, Lewis came back to this experience repeatedly over the course of his life. It was not of transient significance. It marked him for life. Francis Schaeffer experienced a similar post-conversion discovery of the gospel, though in his case it proved to be the turning point of his life and ministry.
