From the Introduction: 'I am not out to decode images or to uncover a system; but I do hope to show how certain central themes hang together - a concern to do justice to the difference of God, the disturbing and exhilarating otherness of what we encounter in the life of faith; a relentless insistence on self-questioning. . . I want to capture something of what Lewis is trying to do in communicating - to a world that frequently thinks it knows what faith is - the character, the feel, of a real experience of surrender in the face of absolute incarnate love. Because that is what matters most: the possibility Lewis still offers of coming across the Christian story as if for the first time.'
