And they are unfruitful because, whilst they last, they yield no real satisfaction. The Apostle could say to another Church with a certainty as to what the answer would be, 'What fruit had ye _then_'--when ye were doing them--'in the things whereof ye are now ashamed?' And the answer is 'None!' Of course, it is true that men do bad things because they like them better than good. Of course, it is true that the misery of mankind is that they have no appetite in the general for the only real satisfaction. But it is also true that no man who feeds his heart and mind on anything short of God is really at rest in anything that he does or possesses. Occasional twinges of conscience, dim perceptions that after all they are walking in a vain show; glimpses of nobler possibilities, a vague unrest, an unwillingness to reflect and look the facts of their condition in the face, like men that will not take stock because they half suspect that they are insolvent--these are the conditions that attach to all godless men's lives. There is no real fruit for their thirsty lips to feed upon. The smallest man is too large to be satisfied with anything short of Infinity, The human heart is like some narrow opening on a hill-side, so narrow that it looks as if a glassful of water would fill it. But it goes away down, down, down into the depths of the mountain, and you may pour in hogsheads and no effect is visible. God, and God alone, brings to the thirsty heart the fruit that it needs.
Another solemn thought illustrates the unfruitfulness of a godless life. There is no correspondence between what such a man does and what he is intended to do. Think of what the most degraded and sensuous wretch that shambles about the slums of a city, sodden with beer and rotten with profligacy, could be. Think of the raptures of devout contemplation and the energies of holy work which are possible for that soul, and then say--though it is an extreme case, the principle holds in less extreme cases--Are these things that men do apart from God, however shining, noble, illustrious they may be in the eyes of the world, and trumpeted forth by the mouthpieces of popular opinion, are these things worth calling fruits fit to be borne by such a tree? No more than the cankers on a rose-bush or the galls on an oak-tree are worthy of being called fruit are these works that some of you have as the only products of a life's activity. 'Wherefore, when I looked that it should bring forth grapes, brought it forth wild grapes?'
II. And now, secondly, notice the plain Christian duty of abstinence.
'Have no fellowship with the unfruitful works of darkness.' Now, the text, as it stands in our version, seems to suggest that these dark works are personified as companions whom a good man ought to avoid; and that, therefore, the bearing of the exhortation is, 'Have nothing to do, in your own individual lives, with evil things that one man can commit.' But I take it that, important as that injunction and prohibition is, the Apostle's meaning is somewhat different, and that my text would perhaps be more accurately translated if another word were substituted for 'have no fellowship with.' The original expression seems rather to mean, 'Do not go partners with other people in works of darkness, which it takes more than one to commit.' Or, to put it into another language, the Apostle is regarding Christian people here as members of society, and exhorting them to a certain course of conduct in reference to plain and palpable existing evils around them. And such an exhortation to the duty of plain abstinence from things that the opinion of the world around us has no objection to, but which are contrary to the light, is addressed to all Christian people.
