The world desperately needs men and women whose sole purpose is to glorify God. It is a sad commentary on the state of the church that many people do not perceive much difference in the way church folks live and the rest of the world. It reminds me of a story about a French light-house keeper who worked near Calais. As he was showing his lighthouse to some guests one day, one of them asked what would happen if one of the lights went out. His response was an emphatic "Never!" He said that if he permitted that to happen, he would live in fear of being responsible for a ship crashing into some unseen rocks along the coast. And then he went on to say, "Sometimes I feel as if the whole world is looking at my light."  That is how we ought to feel  - as if the whole world is looking at our light which glorifies God.
