III. So much upon the laborers. Now for the main point again. GOD HIMSELF IS THE GREAT WORKER. He may use what laborers he pleases, but the increase comes alone from him. Brethren, you know it is so in natural things: the most skilful farmer cannot make the wheat germinate, and grow, and ripen. He cannot even preserve a single field till harvest time, for the farmer's enemies are many and mighty. In husbandry there's many a slip 'twixt the cup and the lip; and when the farmer thinks, good easy man, that he shall reap his crop, there are blights and mildews lingering about to rob him of his gains. God must give the increase. If any man is dependent on God it is the husbandman, and through him we are all of us dependent upon God from year to year for the food by which we live. Even the king must live by the produce of the field. God gives the increase in the barn and the hay-rick; and in the spiritual farm it is even more so, for what can man do in this business? If any of you think that it is an easy thing to win a soul I should like you to attempt it. Suppose that without divine aid you should try to save a soul--you might as well attempt to make a world. Why, you cannot create a fly, how can you create a new heart and a right spirit? Regeneration is a great mystery, it is out of your reach. "The wind bloweth where it listeth, and thou hearest the sound thereof, but canst not tell whence it cometh, and whither it goeth: so is every one that is born of the Spirit." What can you and I do in this matter? it is far beyond our line. We can tell out the truth of God; but to apply that truth to the heart and conscience is quite another thing. I have preached Jesus Christ with my whole heart, and yet I know that I have never produced a saving effect upon a single unregenerate man unless the Spirit of God has opened the heart and placed the living seed of truth within it. Experience teaches us this. Equally is it the Lord's work to keep the seed alive when it springs up. We think we have converts, and we are not long before we are disappointed in them. Many are like blossoms on our apple trees; they are fair to look upon, but they do not come to anything; and others are like the many little apples which fall off long before they have come to any size. He who presides over a great church, and feels an agony for the souls of men, will soon be convinced that if God does not work there will be no work done: we shall see no conversion, no sanctification, no final perseverance, no glory brought to God, no satisfaction for the passion of the Saviour, unless the Lord be with us. Well said our Lord, "Without me ye can do nothing."
