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.
