Light is used as a mark of holiness or right living. Consider, if you will, John 3. Jesus tells Nicodemus that men love darkness better than light because their deeds are evil. He also states that man do good deeds in light for them to be seen. Jesus also states in Matthew’s Gospel that we are to be lights to the world.

So, make sure that you’re doing your work in the light, for the light, to be a light, and to eradicate darkness.
