Matthew 21:28-32 - The Parable Of The Two Sons
28 Tell me what you think. A man had two sons. He went to the first and said, 'Son, go and work in the vineyard to-day';
29 he replied, 'I will go, sir,' but he did not go. 30 The man went to the second and said the same to him; he replied, 'I will not,' but afterwards he changed his mind and did go.
31 Which of the two did the will of the father?" They said, "The last." Jesus said to them, "I tell you truly, the taxgatherers and harlots are going into the Realm of God before you. 32 For John showed you the way to be good and you would not believe him; the taxgatherers and harlots believed him, and even though you saw that, you would not change your mind afterwards and believe him.
