WHAT CHILDREN OF LIGHT SHOULD BE 'Walk as children of light.'--Eph. v. 8. It was our Lord who coined this great name for His disciples. Paul's use of it is probably a reminiscence of the Master's, and so is a hint of the existence of the same teachings as we now find in the existing Gospels, long before their day. Jesus Christ said, 'Believe in the light, that ye may be the children of light'; and Paul gives substantially the same account of the way by which a man becomes a Son of the Light when he says, in the words preceding my text, 'Ye were sometimes darkness, but now are ye light in the Lord.' Union with Him makes light, just as the bit of carbon will glow as long as it is in contact with the electric force, and subsides again into darkness when that is switched off. To be in Christ is to be a child of light, and to believe in Christ is to be in Him. But the intense moral earnestness of our Apostle is indicated by the fact that on both occasions in which he uses this designation he does so, not for the purpose of heightening the sense of the honour and prerogative attached to it, but for the sake of deducing from it plain and stringent moral duties, and heightening the sense of obligation to holy living. 'Walk as children of light.' Be true to your truest, deepest self. Manifest what you are. Let the sweet, sacred secrets of inward communion come out in the trivialities of ordinary conduct; make of your every thought a deed, and see to it that every deed be vitalised and purified by its contact with the great truths and thoughts that lie in this name. These are various ways of putting this one all-sufficient directory of conduct. Now, in the context, the Apostle expands this concentrated exhortation in three or four different directions, and perhaps we may best set forth its meaning if we shape our remarks by these, I venture to cast them, for the sake of emphasis, into a hortatory form. I. Aim at an all-round productiveness of the natural fruits of the light. The true reading is, 'Walk as children of light, for the fruit of the light' (not _spirit_, as the Authorised Version reads it) 'is in all goodness and righteousness and truth.' Now, it is obvious that the alteration of 'light' instead of 'spirit' brings the words into connection with the preceding and the following. The reference to the 'fruits of the spirit' would be entirely irrelevant in this place; a reference to the 'fruit of the _light_,' as being every form of goodness and righteousness and truth, is altogether in place.
