Have you ever turned a flashlight on during the brightness of the day, and it seems useless? On the contrary, have you ever had a flashlight shine in your eyes when it's really dark outside? It seems ultra bright, doesn't it? Pastor David is likening this to the Light of the World. Jesus is that brilliant light that shines in the darkest place. Our world grows darker with each generation. Good is called evil, and evil is called good. Praise God that He doesn't decide our eternal fate based on those around us!
