Sometimes Christian themes are secularized, or lose their meaning.
Lately, the topic of "light" comes up everywhere. I remember how in high school we went around singing DC Talk's "I want to be in the light." Or how about the more recent one, "Into marvelous light I'm running..."? There's also the favorite, "Shine, Jesus, Shine." When we think about what light and darkness represent, of course these words hold meaning for us. But when taken out of context, they aren't so effective.
What does it mean when the light goes on? We all feel something when we see the flicker of a candle, yet what is it exactly that we're feeling?
I had a high school teacher who was Jewish. On the last day of class, he lit a candle and gave a poignant speech about how we could bring light to the world. A Russian teacher here also talked about being a light. Also popular is the theory that "light always conquers darkness." +/-
