We shall never walk as the children of the light, unless we have the habit of referring everything, trifles and great things, to His arbitrament, and seeking in them all to do what is pleasing in His sight. The smallest deed may be brought under the operation of the largest principles. Gravitation influences the microscopic grain of sand as well as planets and sun. There is nothing so small but you can bring it into this category--it either pleases or displeases Jesus Christ. And the faults into which Christian men fall and in which they continue are very largely owing to their carelessness in applying this standard to the small things of their daily lives. The sleepy Custom House officers let the contraband article in because it seems to be of small bulk. There are old stories about how strong castles were taken by armed men hidden in an innocent-looking cart of forage. Do you keep up a rigid inspection at the frontier, and see to it that everything vindicates its right to enter because it is pleasing to Jesus Christ. III. Thirdly, we have here another expansion of the general command, and that is--keep well separate from the darkness. Have no fellowship with the unfruitful works of darkness, but rather reprove them.' Now, your time will not allow me to dwell, as I had hoped to do, upon the considerations to be suggested here. The very briefest possible mention of them is all that I can afford. 'The unfruitful works of darkness';--well, then, the darkness has its works, but though they be works they are not worth calling fruit. That is to say, nothing except the conduct which flows from union with Jesus Christ so corresponds to the man's nature and relations, or has any such permanence about it as to entitle it to be called fruit. Other acts may be 'works' but Paul will not dishonour the great word 'fruit' by applying it to such rubbish as these, and so he brands them as 'unfruitful works of darkness.' Keep well clear of them, says the Apostle. He is not talking here about the relations between Christians and others, but about the relations between Christian men and the _works_ of darkness. Only, of course, in order to avoid fellowship with the works you will sometimes have to keep yourselves well separate from their doers. Much association with such men is forced upon us by circumstances, and much is the imperative duty of Christian beneficence and charity. But I venture to express the strong and growing conviction that there are few exhortations that the secularised Church of this generation needs more than this commandment of my text: 'Have no fellowship with the unfruitful works of darkness' 'What communion hath light with darkness?' Ah! we see plenty of it, unnatural as it is, in the so-called Church of to-day. 'What concord hath Christ with Belial? What part hath he that believeth with an infidel? Come ye out from among them, and be ye separate.'
