Further, note in the context the thought that the conviction of the darkness comes from the flashing upon it of the light. 'All things when they are reproved are made manifest by the light.' Which, being translated into other words, is this:--Be strong in your brave protest, because it only needs that the thing should be seen as it is, and called by its right name, in order to be condemned.
The Assyrians had a belief that if ever, by any chance, a demon saw himself in a mirror, he was frightened at his own ugliness and incontinently fled. And if Christian people would only hold up the mirror of Christian principle to the hosts of evil things that afflict our city and our country, they would vanish like ghosts at sunrise. They cannot stand the light, therefore let us cast the light upon them.
And do not forget the other final principle here, which is imperfectly represented by our translation. We ought to read, 'Whatever is made manifest is light.' Yes. In the physical world when light falls upon a thing, you see it because there is on it a surface of light. And in the moral world the intention of all this conviction is that the thing disclosed to be darkness should, in the very disclosure, cease to be dark, should forsake its nature and be transformed into light. Such transformation is not always the case. Alas! There are evil deeds on which the light falls, and it does nothing. But the purpose in all cases should be, and the issue in many will be, that the merciful conviction by the light will be followed by the conversion of darkness into light.
And so, dear brethren, I bring this text to your hearts, and lay it upon your consciences. We may not all be called upon to speak; we are all called upon to _be_. You can shine, and by shining show how dark the darkness is. The obligation is laid upon us all; the commandment still comes to every Christian which was given to the old prophet, 'Declare unto My people their transgression, and to the house of Jacob their sin.' A quaint old writer says that the presence of a saint 'hinders the devil of elbow room to do his tricks.' We can all rebuke sin by our righteousness, and by our shining reveal the darkness to itself. We do not walk as children of the light unless we keep ourselves from all connivance with works of darkness, and by all means at our disposal reprove and convict them. 'Come out from among them, and be ye separate, and touch no unclean thing, saith the Lord.'
