(29) I will not.--The bold defiance of the answer answers to the rough recklessness of the classes (publicans and harlots) who were represented by the "first" of the two sons. Their whole life, up to the time of their conversion, had been an open refusal to keep God's laws, and so to work in His vineyard.

He repented.--The Greek word is not the same as that of Matthew 3:2, and expresses rather the regretful change of purpose than entire transformation of character. It is the first stage of repentance, and may, as in this instance, pass on into the higher, or, as in the case of Judas (Matthew 27:3, where the same word is used), end only in remorse and despair.

Verse 29. - I will not. The answer is rude, curt, and disrespectful, such a one as would naturally issue from the lips of a person who was selfishly wrapped in his own pleasures, and cared nothing for the Law of God, the claims of relationship, the decencies of society. Repented, and went; i.e. into the vineyard to work. The worst sinners, when converted, often make great saints. There is more hope of their repentance than of the self-righteous or hypocrites, who profess the form of religion without the reality, and in their own view need no repentance.

21:28-32 Parables which give reproof, speak plainly to the offenders, and judge them out of their own mouths. The parable of the two sons sent to work in the vineyard, is to show that those who knew not John's baptism to be of God, were shamed by those who knew it, and owned it. The whole human race are like children whom the Lord has brought up, but they have rebelled against him, only some are more plausible in their disobedience than others. And it often happens, that the daring rebel is brought to repentance and becomes the Lord's servant, while the formalist grows hardened in pride and enmity.He answered and said, I will not,.... Which answer fitly expresses the language and practice of openly profane and unregenerate sinners, who will not come to Christ, that they may have life; nor will they serve the Lord, but are bent upon indulging their lusts; nor will they be subject to the law of God; nor will they hear and receive the Gospel of Christ, or submit to his ordinances, and are averse to every good work: where is man's free will? this is the true picture of it; man has no will naturally to that which is good,

But afterward he repented, and went: a change of mind was wrought in him, and this produced a change of life and conversation: so, many of the publicans and sinners repented of their sins of disobedience, and rebellion against God, under the ministry of John the Baptist, Christ, and his apostles; not of themselves, men do not naturally see their sin, or need of repentance; their hearts are hard and obdurate; nor have they any spiritual sense and feeling: nothing will bring them to repentance, not the most powerful ministry, the severest judgments, or the kindest mercies, without the grace of God: but it was of God, and owing to his powerful and efficacious grace, that they repented: it was his will they should come to repentance: he called them to it, and gave it to them, as a free grace gift of his: and they repented not in a mere legal way, with a legal repentance, which lies in a mere conviction of the outward acts of sin; in an external sorrow for it, in horror and terror of mind about it, and in shedding tears for it, accompanied with a cessation from the grosser acts of sin, and an outward reformation of life and manners: but they repented in an evangelical manner, as such do, who are really converted, and spiritually instructed; who are true believers in Christ, have views, and, at least, hopes of pardoning grace and mercy; and have the love of God shed abroad in their hearts by the Spirit: the repentance of such lies in a spiritual sight and sense of sin, of the evil nature of indwelling sin, and the exceeding sinfulness of it, as well as of the outward actions of life; in a hearty, godly sorrow for it, because committed against a God of purity, grace, and goodness; in a loathing it, and themselves for it; in a holy shame, and blushing, on account of it; and is attended with an ingenuous confession of it, and forsaking it: the consequence of which is, that such go readily and cheerfully into the Lord's vineyard; hear the word with all diligence, receive it with gladness; walk in all the commandments and ordinances of the Lord; and are taught, by the grace that has appeared to them, to live soberly, righteously, and godly in this world.
