As I sit in my living room, coffee nearby, and watch the sun come up, I think perhaps the greatest few words in the Bible are, "Let there be light." In creation, God spoke light into being. There was darkness, then God spoke those words and light entered the world. The light God called day, and the darkness God called night. And God said it was good.
But the light didn't stop there. Thousands and thousands of years later, no one knows how many, God looked at our world and saw darkness. The sun, of course, was still coming up every morning, but he saw a world in desperate need of light; and so, the light that enlightens, the true light, Jesus, came into the world. John tells us in his Gospel, that the light of Jesus shines in the darkness and the darkness cannot overcome it.
But the light doesn't stop there. Jesus then says to his followers, "You are the light of the world." He says to us that we are to let our light shine, so that others may see it and through our light see the glory of Jesus the Christ. I don't know about you, but my light is small compared to the sun God created or compared to the light Christ brought into the world. My light flickers sometimes, like it's about to go out (it needs new batteries!). But because of my commitment to follow Christ, to try and live into his example and his teachings, I have a light - and so do you. Is yours shining?
