“But what do you think? A man had two sons, and he came to the first and said, ‘Son, go, work today in my vineyard.’ 29 He answered and said, ‘I will not,’ but afterward he regretted it and went. 30 Then he came to the second and said likewise. And he answered and said, ‘I go, sir,’ but he did not go. 31 Which of the two did the will of his father?”
They said to Him, “The first.”
Jesus said to them, “Assuredly, I say to you that tax collectors and harlots enter the kingdom of God before you. 32 For John came to you in the way of righteousness, and you did not believe him; but tax collectors and harlots believed him; and when you saw it, you did not afterward relent and believe him.” – Matthew 21:28-32.
Still speaking to the chief priests and elders, He tells them that repentant tax collectors and harlots were entering the kingdom of God before them; whereas they, by their rejection of John’s teachings, were not. He underlines the rightness of the teaching of John the Baptizer on righteousness and repentance.
