When God speaks, he does more than convey information. He changes reality. That was true when he pierced the world’s natural darkness with light in the beginning. It remains true as he speaks to us the good news about Jesus, the light of the world. Through that message he brings us light and enables us to see life as he sees it. This week we see how light attracts people to its source. Just like the glow of a fire attracts people on a dark night in the woods, so also the light that shines forth from Christians attracts people to its source: Christ. God gives Christians time and opportunity to let their lights shine that others would see it and join them in giving glory to God.
