The parable of Jesus Christ about the two sons:
“A man had two sons, and he came to the first and said, ‘Son, go, work today in my vineyard.’ He answered and said, ‘I will not,’ but afterward he regretted it and went. Then he came to the second and said likewise. And he answered and said, ‘I go, sir,’ but he did not go. 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” (Matt. 21:28-31)
