The coming of our Savior was the dawning of a day of light. Isaiah prophesied that "The people who walked in darkness have seen a great light; upon those who dwelt in the land of gloom a light has shone." In the first chapter of John's Gospel we read: "Life was in Him, and Life was the light of men. And the light shines in the darkness, and the darkness did not comprehend it....The true Light, which illuminates every man, was coming into this world." Jesus himself would later say that he was the light of the world. What should our response be to Jesus, the Light? We are called to be children of the light, "rejecting godless ways and worldly desires and living temperately, justly, and devoutly in this age. Or as St. Paul says: "Do not conform to this age, but be transformed by the renewal of your mind, by choosing the will of God, what is good, pleasing and perfect." Walk in the light. Be the light.  Share the light.
