Whereunto shall we liken ... - This shows the great solicitude which Jesus had to adapt his instructions to the capacity of his disciples. He sought out the most plain and striking illustrations - an example which should be followed by all the ministers of the gospel. At the same time that the instructions of the pulpit should be dignified as our Saviour's always were they should be adapted to the capacity of the audience and easily understood. To do this the following things are necessary in a minister:

1."Humility." A freedom from a desire to shine, and to astonish the world by the splendor of his talents, and by his learning and eloquence.

2. "Good sense." A satisfaction in being understood.

3. Acquaintance with the habits of thought and manner of speaking among the people. To do this, frequent contact with them is necessary.

4. "A good sound education." It is the people of ignorance, with some smattering of learning, and with a desire to confound and astonish people by the use of unintelligible words. and by the introduction of matter that is wholly unconnected with the subject, that most often shoot over the heads of the people. Preachers of humility, good sense, and education are content with being understood, and free from the affectation of saying things to amaze and confound their auditors.

The kingdom of God - See the notes at Matthew 3:2.

Whereunto shall we liken the kingdom of God? - How amiable is this carefulness of Jesus! How instructive to the preachers of his word! He is not solicitous to seek fine turns of eloquence to charm the minds of his auditors, nor to draw such descriptions and comparisons as may surprise them: but studies only to make himself understood; to instruct to advantage; to give true ideas of faith and holiness; and to find out such expressions as may render necessary truths easy and intelligible to the meanest capacities. The very wisdom of God seems to be at a loss to find out expressions low enough for the slow apprehensions of men.

How dull and stupid is the creature! How wise and good the Creator! And how foolish the preacher who uses fine and hard words in his preaching, which, though admired by the shallow, convey no instruction to the multitude.

And he said,.... Still continuing his discourse on this subject, and in order to convey to the minds of his disciples clearer ideas of the Gospel dispensation, the success of the Gospel, and the usefulness of their ministration of it, for their encouragement, how unpromising soever things might then be:

whereunto shall we liken the kingdom of God, or with what comparison shall we compare it? It was usual with the Jewish doctors, when about to illustrate anything in a parabolical way to begin with such like questions; as, , "to what is this thing like" (d)? when the answer is to such or such thing, as here.

(d) T. Hieros. Bava Bathra, fol. 16. 2. T. Bab. Zebachim, fol. 82. 1. & Sabbat, fol. 108. 1. & passim.

Peculiar to Mark.

With what comparison shall we compare it? (ἐν τίνι αὐτὴν παραβολῇ θῶμεν;)

Lit., In what parable might we put it? Rev., In what parable shall we set it forth ? Note the we, taking the hearers, with a fine tact, into consultation.

And he said, Whereunto shall we liken the kingdom of God? or with what comparison shall we compare it?

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!
