28 "Tell me what you think of this story: A man had two sons. He went up to the first and said, 'Son, go out for the day and work in the vineyard.' 29 "The son answered, 'I don't want to.' Later on he thought better of it and went. 30 "The father gave the same command to the second son. He answered, 'Sure, glad to.' But he never went. 31 "Which of the two sons did what the father asked?" They said, "The first." 32 John came to you showing you the right road. You turned up your noses at him, but the crooks and whores believed him. Even when you saw their changed lives, you didn't care enough to change and believe him.

Commentary on Matthew 21:28-32
(Read Matthew 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.
