The light has come into the world, and people who do evil things are judged guilty because they love the dark more than the light. People who do evil hate the light and won't come to the light, because it clearly shows what they have done. But everyone who lives by the truth will come to the light, because they want others to know that God is really the one doing what they do.
As a follower of Jesus Christ are you doing things for God or is God doing things through you? There is a big difference.
When you do things for God you want His approval and you want the reward that might come from pleasing Him. But when God does things through you He is using you as His vessel to accomplish His will on this earth! You are then the light of the world but God Himself is the electricity in your light bulb!
Thomas Edison did not invent electricity. Edison simply created a way of allowing the world to see the light that electric power makes. Christians have no power of their own to show the world the way to Heaven. The light of the world is Jesus Christ, but you are the light bulb through which His power is displayed!
When a light bulb is disconnected from the source of power it is perhaps the most useless of all items! The same is true for a follower of Jesus. When you are disconnected from Jesus Christ you have no way to be the light of the world!
"Lord Jesus, help me today to stay plugged in to You so that I may shine in the darkness of this world with the light that only comes from You. And may You be praised forever! Amen."
