21 He said to them, "Is a lamp brought in to be put under the bushel basket, or under the bed, and not on the lampstand? 22 For there is nothing hidden, except to be disclosed; nor is anything secret, except to come to light. 23 Let anyone with ears to hear listen!" 24 And he said to them, "Pay attention to what you hear; the measure you give will be the measure you get, and still more will be given you. 25 For to those who have, more will be given; and from those who have nothing, even what they have will be taken away."
26 He also said, "The kingdom of God is as if someone would scatter seed on the ground, 27 and would sleep and rise night and day, and the seed would sprout and grow, he does not know how. 28 The earth produces of itself, first the stalk, then the head, then the full grain in the head. 29 But when the grain is ripe, at once he goes in with his sickle, because the harvest has come."
30 He also said, "With what can we compare the kingdom of God, or what parable will we use for it? 31 It is like a mustard seed, which, when sown upon the ground, is the smallest of all the seeds on earth; 32 yet when it is sown it grows up and becomes the greatest of all shrubs, and puts forth large branches, so that the birds of the air can make nests in its shade."
33 With many such parables he spoke the word to them, as they were able to hear it; 34 he did not speak to them except in parables, but he explained everything in private to his disciples.

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!
