For little though it seem to teach the simple truth of the gospel, yet it is essential. How shall men hear without a teacher? Servants of God, the seed of the word is not like thistle-down, which is borne by every wind; but the wheat of the kingdom needs a human hand to sow it, and without such agency it will not enter into men's hearts, neither can it bring forth fruit to the glory of God. The preaching of the gospel is the necessity of every age; God grant that our country may never be deprived of it. Even if the Lord should send us a famine of bread and of water, may he never send us a famine of the word of God. Faith cometh by hearing, and how can there be hearing if there is no teaching? Scatter ye, scatter ye, then, the seed of the kingdom, for this is essential to the harvest.

This seed should be sown often, for many are the foes of the wheat, and if you repeat not your sowing you may never see a harvest. The seed must be sown everywhere, too, for there are no choice corners of the world that you can afford to let alone, in the hope that they will be self-productive. You may not leave the rich and intelligent under the notion that surely the gospel will be found among them, for it is not so: the pride of life leads them away from God. You may not leave the poor and illiterate, and say, "Surely they will of themselves feel their need of Christ." Not so: they will sink from degradation to degradation unless you uplift them with the gospel. No tribe of man, no peculiar constitution of the human mind, may be neglected by us; but everywhere we must preach the word, in season and out of season. I have heard that Captain Cook, the celebrated circumnavigator, in whatever part of the earth he landed, took with him a little packet of English seeds, and scattered them in suitable places. He would leave the boat and wander up from the shore. He said nothing, but quietly scattered the seeds wherever he went, so that he belted the world with the flowers and herbs of his native land. Imitate him wherever you go; sow spiritual seed in every place that your foot shall tread upon.

Let us now think of what you cannot do. You cannot, after the seed has left your hand, cause it to put forth life. I am sure you cannot make it grow, for you do not know how it grows. The text saith, "And the seed should spring and grow up, he knoweth not how." That which is beyond the range of our knowledge is certainly beyond the reach of our power. Can you make a seed germinate? You may place it under circumstances of damp and heat which will cause it to swell and break forth with a shoot, but the germination itself is beyond you. How is it done? We know not. After the germ has been put forth, can you make it further grow, and develop its life into leaf and stem? No; that, too, is out of your power. And when the green, grassy blade has been succeeded by the ear, can you ripen it? It will be ripened; but can you do it? You know you cannot; you can have no finger in the actual process, though you may promote the conditions under which it is carried on. Life is a mystery; growth is a mystery; ripening is a mystery: and these three mysteries are as fountains sealed against all intrusion. How comes it that there is within the ripe seed the preparations for another sowing and another growth? What is this vital principle, this secret reproducing energy? Knowest thou anything about this? The philosopher may talk about chemical combinations, and he may proceed to quote analogies from this and that; but still the growth of the seed remains a secret; it springs up, he knoweth not how. Certainly this is true of the rise and progress of the life of God in the heart. It enters the soul, and roots itself we know not how. Naturally men hate the word, but it enters and it changes their hearts, so that they come to love it; yet we know not how. Their whole nature is renewed, so that instead of producing sin it yields repentance, faith, and love; but we know not how. How the Spirit of God deals with the mind of man, how he creates the new heart and the right spirit, how we are begotten again unto a lively hope, we cannot tell. The Holy Ghost enters into us; we hear not his voice, we see not his light, we feel not his touch; yet he worketh an effectual work upon us, which we are not long in perceiving. We know that the work of the Spirit is a new creation, a resurrection, a quickening from the dead; but all these words are only covers to our utter ignorance of the mode of his working, with which it is not in our power to meddle. We do not know how he performs his miracles of love, and, not knowing how he works, we may be quite sure that we cannot take the work out of his hands. We cannot create, we cannot quicken, we cannot transform, we cannot regenerate, we cannot save.

This work of God having proceeded in the growth of the seed, what next? We can reap the ripe ears. After a season God the Holy Spirit uses his servants again. As soon as the living seed has produced first of all the blade of thought, and afterwards the green ear of conviction, and then faith, which is as full corn in the ear, then the Christian worker comes in for further service, for he can reap. "When the fruit is brought forth, immediately he putteth in the sickle." This is not the reaping of the last great day, for that does not come within the scope of the parable, which evidently relates to a human sower and reaper. The kind of reaping which the Saviour here intends is that which he referred to when he said to his disciples, "Lift up your eyes, and look on the fields; for they are white already to harvest." After he had been sowing the seed in the hearts of the Samaritans, and it had sprung up, so that they began to evince faith in him, the Lord Jesus cried, "The fields are white to harvest." The apostle saith, "One soweth, and another reapeth." Our Lord said to the disciples, "I sent you to reap that whereon ye bestowed no labor." Is there not a promise, "In due season we shall reap, if we faint not"?

Christian workers begin their harvest work by watching for signs of faith in Christ. They are eager to see the blade, and delighted to mark the ripening ear. They often hope that men are believers, but they long to be sure of it; and when they judge that at last the fruit of faith is put forth, they begin to encourage, to congratulate, and to comfort. They know that the young believer needs to be housed in the barn of Christian fellowship, that he may be saved from a thousand perils. No wise farmer leaves the fruit of the field long exposed to the hail which might beat it out, or to the mildew which might destroy it, or to the birds which might devour it. Evidently no believing man should be left outside of the garner of holy fellowship; he should be carried into the midst of the church with all the joy which attends the home-bringing of sheaves. The worker for Christ watches carefully, and when he discerns that his time is come, he begins at once to fetch in the converts, that they may be cared for by the brotherhood, separated from the world, screened from temptation, and laid up for the Lord. He is diligent to do it at once, because the text saith, "immediately he putteth in the sickle." He does not wait for months in cold suspicion; he is not afraid that he shall encourage too soon when faith is really present. He comes with the word of promise and the smile of brotherly love at once, and he says to the new believer, "Have you confessed your faith? Is not the time come for an open confession? Hath not Jesus bidden the believer to be baptized? If you love him, keep his commandments." He does not rest till he has introduced the convert to the communion of the faithful. For our work, beloved, is but half done when men are made disciples and baptized. We have then to encourage, to instruct, to strengthen, to console, and succor in all times of difficulty and danger. What saith the Saviour? "Go ye therefore, and make disciples of all the nations, baptizing them into the name of the Father, and of the Son, and of the Holy Ghost: teaching them to observe all things whatsoever I have commanded you."

Observe, then, the sphere and limit of agency. We can introduce the truth to men, but that truth the Lord himself must bless; the living and growing of the word within the soul is of God alone. When the mystic work of growth is done, we are able to garner the saved ones in the church. For Christ to be formed in men the hope of glory is not of our working, that remains with God; but, when Jesus Christ is formed in them, to discern the image of the Saviour and to say, "Come in, thou blessed of the Lord, wherefore standest thou without?" this is our duty and delight. To create the divine life is God's, to cherish it is ours. To cause the hidden life to grow is the work of the Lord; to see the uprising and development of that life and to harvest it is the work of the faithful, even as it is written, "When the fruit is brought forth, immediately he putteth in the sickle, because the harvest is come."

This, then, is our first lesson; we see what we can do and what we cannot do.

II. Our second head is like unto the first, and consists of what we can know and what we cannot know.

First, what we can know. We can know when we have sown the good seed of the word that it will grow; for God has promised that it shall do so. Not every grain in every place; for some will go to the bird, and some to the worm, and some to be scorched by the sun; but, as a general rule, God's word shall not return unto him void, it shall prosper in the thing whereto he hath sent it. This we can know. And we can know that the seed when once it takes root will continue to grow; that it is not a dream or a picture that will disappear, but a thing of force and energy, which will advance from a grassy blade to corn in the ear, and under God's blessing will develop to actual salvation, and be as the "full corn in the ear." God helping and blessing it, our work of teaching will not only lead men to thought and conviction, but to conversion and eternal life.

We also can know, because we are told so, that the reason for this is mainly because there is life in the word. In the word of God itself there is life, for it is written—"The word of God is quick and powerful," that is, "living and powerful." It is "the incorruptible seed which liveth and abideth for ever." It is the nature of living seeds to grow; and the reason why the word of God grows in men's hearts is because it is the living word of the living God, and where the word of a king is there is power. We know this, because the Scriptures teach us so. Is it not written, "Of his own will begat he us by the word of truth"?
