“And he came to the first, and said, ‘Son, go work today in the vineyard'. And he answered and said, ‘I will not', but afterward he changed his mind, and went.”
The first son is called to work in his father's vineyard, but rudely refuses. However, afterwards he changes his mind and goes. He is a picture of all who for a time rudely ignore God but afterwards repent and begin to obey Him.
