Christ is the Light of the World; the sun which shines upon everything; gives colour to everything; heals and gives life, light, and heat; the warmth that goes down deep to the root of the tree and discovers the tiniest seedling in the darkness and feeds it and draws it up into the day. But it is not only as the light of the sun that Christ wishes to be seen, but also as the little candle burning in the house, a candle in a dark room.
