I am the light of the world, the founder of the Christian religion said. What a stupendous phrase! And how particularly marvelous today, when one is conscious of so much darkness in the world! Let your light shine before men, he exhorted us. You know, sometimes ... someone asks me what I most want, what I should most like to do in the little that remains of my life, and I always nowadays truthfully answer--and it is truthful--"I should like my light to shine, even if only very fitfully, like a match struck in a dark, cavernous night and then flickering out."
