21:32 For John came unto you in the {q} way of righteousness, and ye believed him not: but the publicans and the harlots believed him: and ye, when ye had seen [it], repented not afterward, that ye might believe him.
(q) Living uprightly, being of good and honest behaviour; For the Hebrews use this word way for life and manners.
21:32 Repented not afterward. The Greek word here translated repent, is not the one which is used in all commands as, Repent, for the kingdom of heaven is at hand (Mt 3:2), Repent and be baptized (Ac 2:38), Repent and be converted (Ac 3:19), etc. This term metamellomai means, rather, regret or sorrow; the word in the other passages, metanoeo, means change your minds or hearts. The regret, or sorrow, for sin leads to repentance (2Co 7:10). The scribes and Pharisees did not regret their course, when they saw sinners repenting, so that they could come into a penitent belief.
21:32 John came in a way of righteousness - Walking in it, as well as teaching it. The publicans and harlots - The most notorious sinners were reformed, though at first they said, I will not. And ye seeing the amazing change which was wrought in them, though at first ye said, I go, sir, repented not afterward - Were no more convinced than before. O how is this scripture fulfilled at this day!
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.
