Then, still further, there is implied in this great requirement of walking in the light, not only activity and effort, and progress and purity, but also that the whole of the life shall be brought into relation with, and shall be moulded after, the pattern of the God in whom we profess to believe. Religion, in its deepest meaning, is the aspiration after likeness to the god. You see it in heathenism. Men make their gods after their own image, and then the god makes the worshippers after his image. Mars is the god of the soldier, and Venus goddess of the profligate, and Apollo god of the musical and the wise, etc., and in Christianity the deepest thing in it is aspiration and effort after likeness to God. Love is imitation; admiration, especially when it is raised to the highest degree and becomes adoration, is imitation. And the man that lies before God, like a mirror in the sunshine, receives on the still surface of his soul--but not, like the mirror, on the surface only, but down into its deepest depths--the reflected image of Him on Whom he gazes. 'We all with unveiled face, mirroring glory, are changed into the same image.' So to walk in the light is only possible when we are drawn into it, and our feeble feet made fit to tread upon the radiant glory, by the thought that He is in the light. To imitate Him is to be righteous. So do not let us forget that a correct creed, and devout emotions, ay! and a morality which has no connection with Him, are all imperfect, and that the end of all our religion, our orthodox creed and our sweet emotions and inward feelings of acceptance and favour and fellowship, are meant to converge on, and to produce this--a life and a character which lives and moves and has its being in a great orb of light and purity.
But another thing is included in this grand metaphor of my text. Not only does it enjoin upon us effort and activity and progress in the light and the linking of all our purity with God, but also, it bids us shroud no part of our conduct or our character either from ourselves or from Him. Bring it all out into the light. And although with a penitent heart, and a face suffused with blushes, we have sometimes to say, 'See, Father, what I have done!' it is far better that the revealing light should shine down upon us, and like the sunshine on wet linen, melt away the foulness which it touches, than that we should huddle the ugly thing up in a corner, to be one day revealed and transfixed by the flash of the light turned into lightning. 'He that doeth the truth cometh to the light, that his deeds may be made manifest.'
II. So much, then, for my first point; the second is: The companions of the men that walk in the light.
I have already pointed out that the accurate, perhaps pedantically accurate, form of the antithesis would have been: 'If we walk in the light as He is in the light, we have fellowship with God.' But John says, first, 'we have fellowship one with another.' Underlying that, as I shall have to say in a moment, there is the other thought: 'We have fellowship with God.' But he deals with the other side of the truth first. That just comes to this, that the only cement that perfectly knits men to each other is their common possession of that light, and the consequent fellowship with God. There are plenty of other bonds that draw us to one another; but these, if they are not strengthened by this deepest of all bonds, the affinity of souls, that are moving together in the realm of light and purity, are precarious, and apt to snap. Sin separates men quite as much as it separates each man from God. It is the wedge driven into the tree that rends it apart. Human society with its various bonds is like the iron hoop that may be put around the barrel staves, giving them a quasi-unity. The one thing that builds men together into a whole is that each shall be, as it were, embedded in the rock which is the foundation, and the building will rise into a holy temple in the Lord. Sin separates; as the prophet confessed, 'All we like sheep have gone astray, every one to _his own way_,' and the flock is broken up into a multitude of scattered sheep. Social enthusiasts may learn the lesson that the only way by which brotherhood among men can become anything else than a name, and probably end, as it did in the great French Revolution, in 'brothers' making hecatombs of their brethren under the guillotine, is that it shall be the corollary from the Fatherhood of God. If we walk in the light, not otherwise, we have 'fellowship one with another.'
