Read Proverbs 6:23  It is easy for us to get around in the daytime.  We can see chairs and tables that we might bang our shins on.  But at night, well that is a different matter.  At night you had better have a light on or you might bang into everything.  If the electricity goes off we need to have a flashlight nearby in order to see where we are going.  If we don't, we may not be able to safely get around.  Our verse uses this illustration of light and a lamp to explain life.  Getting through life is like walking through our house.  If we have light to see things, we can go through our house just fine.  If we have direction from the Bible, God's Word, we can get through life just fine.  But if our room is dark, we may stumble on things that we cannot see.  Without God's light in our lives, our life will be dark and we may stumble on things and not be able to go safely through life.  We need God's light.  We need God's direction.  In the New Testament, Jesus said that men light a candle and put it on a candlestick in order to give light to the entire room.  Jesus is our light, and we, in turn, are God's light to the rest of the world.  God gives us light to know how to live, and we, in turn, give God's light to others!  We help God get His light out to the dark world!
