(27) And should sleep, and rise.--So it was in the world's history. Men knew not the greatness of the new force that had been brought into action. Philosophers and statesmen ignored it. Even the very preachers of the new faith, the "sowers" of the parable, were hardly conscious of the enormous revolution which they were working. So it is in the individual life. The seemingly chance word, the new truth that flashes on the soul as a revelation, the old words now for the first time apprehended in their true force, these prove to be the seeds of a new growth in the soul.

4:21-34 These declarations were intended to call the attention of the disciples to the word of Christ. By his thus instructing them, they were made able to instruct others; as candles are lighted, not to be covered, but to be placed on a candlestick, that they may give light to a room. This parable of the good seed, shows the manner in which the kingdom of God makes progress in the world. Let but the word of Christ have the place it ought to have in a soul, and it will show itself in a good conversation. It grows gradually: first the blade; then the ear; after that the full corn in the ear. When it is sprung up, it will go forward. The work of grace in the soul is, at first, but the day of small things; yet it has mighty products even now, while it is in its growth; but what will there be when it is perfected in heaven!And should sleep,.... That is, the man that casts in the seed, who represents the ministers of the Gospel: and, as applied to them, is not to be understood of natural sleep, and indulging themselves in that; much less of spiritual sloth and indolence, as if they cared not what became of the seed sown, whether it sprung up, and came to any thing, or not; for neither of these belong to the characters of the true ministers of the word: for though bodily sleep in them, as in other men, is necessary for the support of nature, and to put them in a capacity of discharging their work; yet perhaps none have less of it than studious and laborious preachers of the Gospel; and much less do they indulge a spiritual sleep and slothfulness; though this may sometimes attend them, as well as others: but then, whilst they sleep, in this sense, tares are sown, and they spring up, and not the good seed of the word, as in this parable; besides, as they labour in the word and doctrine, by studying and preaching it, so they follow their ministrations with incessant prayers that they be succeeded to the conversion of sinners, and comfort of saints; nor can they be easy, unless they have some seals of their ministry: but rather, this may be understood of the sleep of death; for so it often is, that the seed sown by them does not appear in the fruits of it to the churches of Christ, among whom they have ministered, until after they are fallen asleep in Jesus: though it seems best to understand it of their holy security, confidence, and satisfaction in their own minds, that it will turn to profit and advantage, both to the good of souls, and glory of God, not despairing of success; but having left their work with their Lord, they sit down easy and satisfied, believing that the word shall prosper to the thing whereunto it is sent:

and rise night and day; which shows their diligence and laboriousness, and their constant attendance to other parts of their work, rising up early, and sitting up late, to prepare for, and discharge their ministerial work; and their continued expectation of the springing-up of the seed sown, which accordingly does in proper time:

and the seed should spring and grow up, he knoweth not how; it is a mystery in nature, how the seed under the clods, where it dies before it is quickened, should spring and grow up, and bring forth fruit; and so it is in grace, how the word of God first operates on a sinner's heart, and becomes the ingrafted word there; the time when, and much less the manner how, grace, by this means, is implanted in the heart, are not known to a soul itself, and still less to the ministers of the word, who sometimes never know any thing of it; and when they do, not till some time after: this work is done secretly, and powerfully, under the influence of divine grace, without their knowledge, though by them as instruments; so that though the sowing and planting are theirs, all the increase is God's: this may encourage attendance on the ministry of the word, and teach us to ascribe the work of conversion entirely to the power and grace of God.
