Grace strikes us when we are in great pain and restlessness. It strikes us when we walk through the valley of a meaningless and empty life. It strikes us when our disgust for our own being, our indifference, our weakness, our hostility, and our lack of direction and composure have become intolerable to us. It strikes us when, year after year, the longed-for perfection of life does not appear, when the old compulsions reign within us as they have for decades, when despair destroys all joy and courage. Sometimes at that moment a wave of light breaks into our darkness, and it as though a voice were saying: "You are accepted."
