13:31-35 The scope of the parable of the seed sown, is to show that the beginnings of the gospel would be small, but its latter end would greatly increase; in this way the work of grace in the heart, the kingdom of God within us, would be carried on. In the soul where grace truly is, it will grow really; though perhaps at first not to be discerned, it will at last come to great strength and usefulness. The preaching of the gospel works like leaven in the hearts of those who receive it. The leaven works certainly, so does the word, yet gradually. It works silently, and without being seen, Mr 4:26-29, yet strongly; without noise, for so is the way of the Spirit, but without fail. Thus it was in the world. The apostles, by preaching the gospel, hid a handful of leaven in the great mass of mankind. It was made powerful by the Spirit of the Lord of hosts, who works, and none can hinder. Thus it is in the heart. When the gospel comes into the soul, it works a thorough change; it spreads itself into all the powers and faculties of the soul, and alters the property even of the members of the body, Ro 6:13. From these parables we are taught to expect a gradual progress; therefore let us inquire, Are we growing in grace? and in holy principles and habits?

36-38. Then Jesus sent the multitude away, and went into the house: and his disciples came unto him, saying, Declare unto us the parable of the tares of the field, &c.—In the parable of the Sower, "the seed is the word of God" (Lu 8:11). But here that word has been received into the heart, and has converted him that received it into a new creature, a "child of the kingdom," according to that saying of James (Jas 1:18), "Of His own will begat He us with the word of truth, that we should be a kind of first-fruits of His creatures." It is worthy of notice that this vast field of the world is here said to be Christ's own—"His field," says the parable. (See Ps 2:8).
