"Coming to his senses he thought, ‘How many of my father’s hired workers have more than enough food to eat, but here am I, dying from hunger. I shall get up and go to my father and I shall say to him, “Father, I have sinned against heaven and against you. I no longer deserve to be called your son; treat me as you would treat one of your hired workers.”’ So he got up and went back to his father. While he was still a long way off, his father caught sight of him, and was filled with compassion. He ran to his son, embraced him and kissed him." (Luke 17-20)
When the prodigal son finally decided to go home, it’s not so much because he is penitent, but because he is starving. However, this does not stop the father—who has been looking out for his lost son—from running out to embrace him. The father’s acceptance would have perplexed the Jewish audience, as they would have seen this as completely unjust.
