"You are the light of the world. A city on a hill cannot be hidden. Neither do people light a lamp and put it under a bowl. Instead they put it on its stand, and it gives light to everyone in the house. In the same way, let your light shine before men, that they may see your good deeds and praise your Father in heaven" (Matthew 5:14-16).
Remember the medieval paintings with haloes over the heads of all the holy people? I've always thought that those haloes represented the light that shown from the faces of the people who loved God and radiated his goodness wherever they went. If so, we are all supposed to have haloes. Christians are intended to light the entire world. That is a lot of darkness to dispel. The light of Christ within us cannot overcome the darkness of the world if we don't put ourselves where we can do the most good - wherever there is darkness.
For reflection: How is my halo today? Where can I bring light?
Let us pray. Jesus, I always considered you the light of the world. But you said that we are the light of the world.
