Into good ground - Those whose hearts are prepared by grace to receive it honestly, and to give it full opportunity to grow.

In a rich and mellow soil - in a heart that submits itself to the full influence of truth, unchecked by cares and anxieties; under the showers and summer suns of divine grace; with the heart spread open, like a broad, luxuriant field, to the rays of the morning and to evening dews, the gospel takes deep root and grows; it has full room, and then and there only shows "what it is."

Good ground - That which had depth of mould, was well ploughed, and well weeded.

Is he that heareth - Who diligently attends the ministry of the word.

And understandeth it - Lays the subject to heart, deeply weighing its nature, design, and importance.

Which also beareth fruit - His fruitfulness being an almost necessary consequence of his thus laying the Divine message to heart. Let it be observed, that to hear, to understand, and to bring forth fruit, are the three grand evidences of a genuine believer. He who does not hear the word of wisdom cannot understand what makes for his peace; and he who does not understand what the Gospel requires him to be and to perform, cannot bring forth fruit; and he who is not fruitful, very fruitful, cannot be a disciple of Christ - see John 15:8; and he who is not Christ's disciple cannot enter into the kingdom of God.

From the different portions of fruit produced by the good ground, a hundred, sixty, and thirty, we may learn that all sound believers are not equally fruitful; all hear, understand, and bring forth fruit, but not in the same degrees-occasioned, partly, by their situation and circumstances not allowing them such extensive opportunities of receiving and doing good; and, partly, by lack of mental capacity - for every mind is not equally improvable.

Let it be farther observed that the unfruitfulness of the different lands was not owing to bad seed or an unskilful sower - the same sower sows the same seed in all, and with the same gracious design - but it is unfruitful in many because they are careless, inattentive, and worldly-minded.

But is not the ground naturally bad in every heart? Undoubtedly. And can any but God make it good? None. But it is your business, when you hear of the justice and mercy of God, to implore him to work in you that which is pleasing in his sight. No man shall be condemned because he did not change his own heart, but because he did not cry to God to change it, who gave him his Holy Spirit for this very purpose, and which he, by his worldly-mindedness and impiety, quenched. Whoso hath ears to hear let him hear: and may the Lord save the reader from an impenitent and unfruitful heart!

But he that received seed into the good ground,.... The hearer compared to good ground into which the seed fell, is he that heareth the word and understandeth it; has a new and spiritual understanding given him, feels the power of it on his heart, enlightening and quickening him; has an application of it made to him by the Spirit of God, and can discern the worth and excellency of it, and distinguish it from all others; and, as Mark says, "receives it"; as the word of God in faith, and with the love of it, and with all readiness and meekness; and, as Luke observes, "keeps it"; holds it fast against all opposition with great struggling; will not part with it at any rate, nor depart from it in the least, nor entertain any doubt about it; but abides by it, stands fast in it, and is valiant for it: and this he does in and with "an honest and good heart"; which no man naturally has; nor can any man make his heart so: this is the work of God, and is owing to his efficacious grace. This is an heart of flesh, a new and right heart, and spirit; an heart to fear God, to love him, and to trust in him; in which Christ dwells by faith; in which the Spirit of God has his temple; and in which every grace is implanted: and such an one, as he hears with a strict, and an honest intention, and in the exercise of grace; so he holds fast the word he hears, understands and receives, with all faithfulness and honesty:

which also beareth fruit and bringeth forth, some an hundred fold, some sixty, and some thirty: the fruit bore, and brought forth by such an hearer, is the true fruit of grace and righteousness, and is all from Christ, under the influences of the Spirit, through the word and ordinances, as means, and issues in the glory of God; and though not brought forth in the same quantity in all, yet is of the same quality; and is brought forth, as Luke says, "with patience": constantly, and continually, in all seasons, in old age, and even unto death; and is at last brought "to perfection", holds, and remains unto the end.

Understandeth (συνιείς)

See on Matthew 11:25, prudent. The three evangelists give three characteristics of the good hearer. Matthew, he understandeth the word; Mark, he receiveth it; Luke, he keepeth it

But he that received seed into the good ground is he that heareth the word, and understandeth it; which also beareth fruit, and bringeth forth, some an hundredfold, some sixty, some thirty.

13:18-23 Hear ye therefore the parable of the sower. In order to understand the parable we must listen to the explanation given in Mt 13:18-23. Christ is the great Sower, and all whom he sends forth to preach are sowers under him. The seed sown is His Word, the Gospel of the Kingdom. The soil is human hearts. Four kinds of human hearts are described: (1) The wayside hearer; the light, flippant, indifferent hearer upon whom no impression is produced. (2) The stony hearer; the heart that exhibits an evanescent feeling at the appeal of the gospel; but upon whom no permanent impression is made. (3) The thorny soil; the heart that takes in the Word, but is so full of worldly cares that these presently gain the mastery. This describes the world-serving hearer. (4) The good soil; the good and honest heart; the heart that receives and retains the truth. In such a heart the seed will grow and the new life will be manifest. Three things, then, are needful: (1) A Sower. (2) Good Seed, the pure word of God. (3) A good and honest heart. A dishonest man cannot be converted until he casts out his dishonesty. He who cavils at and deceitfully entreats the word of God will not be profited.

13:23 Some a hundred fold, some sixty, some thirty - That is, in various proportions; some abundantly more than others.

13:1-23 Jesus entered into a boat that he might be the less pressed, and be the better heard by the people. By this he teaches us in the outward circumstances of worship not to covet that which is stately, but to make the best of the conveniences God in his providence allots to us. Christ taught in parables. Thereby the things of God were made more plain and easy to those willing to be taught, and at the same time more difficult and obscure to those who were willingly ignorant. The parable of the sower is plain. The seed sown is the word of God. The sower is our Lord Jesus Christ, by himself, or by his ministers. Preaching to a multitude is sowing the corn; we know not where it will light. Some sort of ground, though we take ever so much pains with it, brings forth no fruit to purpose, while the good soil brings forth plentifully. So it is with the hearts of men, whose different characters are here described by four sorts of ground. Careless, trifling hearers, are an easy prey to Satan; who, as he is the great murderer of souls, so he is the great thief of sermons, and will be sure to rob us of the word, if we take not care to keep it. Hypocrites, like the stony ground, often get the start of true Christians in the shows of profession. Many are glad to hear a good sermon, who do not profit by it. They are told of free salvation, of the believer's privileges, and the happiness of heaven; and, without any change of heart, without any abiding conviction of their own depravity, their need of a Saviour, or the excellence of holiness, they soon profess an unwarranted assurance. But when some heavy trial threatens them, or some sinful advantage may be had, they give up or disguise their profession, or turn to some easier system. Worldly cares are fitly compared to thorns, for they came in with sin, and are a fruit of the curse; they are good in their place to stop a gap, but a man must be well armed that has much to do with them; they are entangling, vexing, scratching, and their end is to be burned, Heb 6:8. Worldly cares are great hinderances to our profiting by the word of God. The deceitfulness of riches does the mischief; they cannot be said to deceive us unless we put our trust in them, then they choke the good seed. What distinguished the good ground was fruitfulness. By this true Christians are distinguished from hypocrites. Christ does not say that this good ground has no stones in it, or no thorns; but none that could hinder its fruitfulness. All are not alike; we should aim at the highest, to bring forth most fruit. The sense of hearing cannot be better employed than in hearing God's word; and let us look to ourselves that we may know what sort of hearers we are.
