“This is the condemnation,” said Jesus, “that light is come into the world.” And this condemnation every one who walks in Christ’s steps, and breathes His Spirit amid the corruptions of the world, is carrying on, more frequently in silence than by spoken argument. Our unconscious and spontaneous influence is the most real and effective part of it. Life is the light of men--words only as the index of the life from which they spring. Just so far as our lives touch the conscience of others and reveal the difference between darkness and light, so far do we hold forth the word of life and carry on the Holy Spirit’s work in convincing the world of sin. “Let your light so shine.” This manifestation leads to a transformation: “For everything that is made manifest _is light_” (ver. 13). “You are light in the Lord,” St Paul says to his converted Gentile readers,--you who were “once darkness,” once wandering in the lusts and pleasures of the heathen around you, without hope and without God. The light of the gospel disclosed, and then dispelled the darkness of that former time; and so it may be with your still heathen kindred, through the light you bring to them. So it will be with the night of sin that is spread over the world. The light which shines upon sin-laden and sorrowful hearts, shines on them to change them into its own nature. _The manifested is light_: in other words, if men can be made to see the true nature of their sin, they will forsake it. If the light can but penetrate their conscience, it will save them. “Wherefore He saith:-- Awake, O sleeper; and arise from out of the dead! And the Christ shall dawn upon thee!”
