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.'
'And have no fellowship with the unfruitful works of darkness, but rather reprove them. 12. For it is a shame even to speak of those things which are done of them in secret. 13. But all things that are reproved are made manifest by the light: for whatsoever doth make manifest is light. 14. Wherefore he saith, Awake thou that sleepest, and arise from the dead, and Christ shall give thee light. 15. See then that ye walk circumspectly, not as fools, but as wise, 16. Redeeming the time, because the days are evil. 17. Wherefore be ye not unwise, but understanding what the will of the Lord is. 18. And be not drunk with wine, wherein is excess; but be filled with the Spirit; 19. Speaking to yourselves in psalms, and hymns, and spiritual songs, singing and making melody in your heart to the Lord; 20. Giving thanks always for all things unto God and the Father in the name of our Lord Jesus Christ; 21. Submitting yourselves one to another in the fear of God.'--Eph. v. 11-21.
There are three groups of practical exhortations in this passage, of which the first deals with the Christian as a reproving light in darkness; the second, with the Christian life as wisdom in the midst of folly; and the third with Christian sobriety and inspiration as the true exhilaration in contrast with riotous drunkenness. Probably such intoxication was prevalent in Ephesus in connection with the worship of 'Diana of the Ephesians,' for Paul was not the man to preach vague warnings against vices to which his hearers were not tempted. An under-current of allusion to such orgies accompanying the popular cult may be discerned in his words.
These two preceding sets of precepts can only be briefly touched on now. They lead up to the third, and the second is built on the first by a 'therefore' (ver. 15). The Apostle has just been saying that Christians were 'darkness, but are now light in the Lord,' and thence drawing the law for their life, to walk as 'children of light.' A very important part of such walk is recoiling from all share in 'the unfruitful works of darkness,'--a significant expression branding such deeds as being both bad in their source and in their results. Dark doings have consequences tragic enough and certain enough, but they are barren of all such issues as correspond to men's obligations and capacities. Their outcome is like the growths on a tree, which are not fruit, but products of disease. There is no fruit grown in the dark; there is no worthy product from us unless Christ is our light. If He is, and we are therefore 'light in the Lord,' we shall 'reprove' or 'convict' the Christless life. Its sinfulness will be shown by the contrast with the Christ-life. A thunder-cloud never looks so lividly black as when smitten by sunshine.
