What I found interesting about this passage was that I initially found myself thinking like the righteous persons when reading this passage. When the father of the prodigal son praised the son who returned and the loyal one got upset, I understood where he was coming from. I almost started to feel like I should become a sinner so that I can repent later and God can rejoice. However, when I read that his father said to him: “Son, you are always with me, and all that is mine is yours” (Luke 15:31), I interpreted this to mean that God does not view his loyal righteous people as less than the sinners who have repented, he has already accepted them and rejoices in their company. Even though Jesus show’s how the son was welcomed back with open arms, he does not further elaborate upon what happened to the prodigal son. His father had already given him his share of the farm, So I assume he will no longer inherit the land. Upon further reflection of this parable, I conclude that it is essential for us to stay loyal and righteous in God’s eyes, and rather than getting jealous for a sinner being praised for repentance, we should join God in that rejoiceful appraisal of someone turning from evil and entering the kingdom of God.
In fact, it seems as though calling the people righteous persons in the text is actually a bit ironic. At the time, according to the people of the world, being “righteous” simply meant that they piously followed the Jewish customs of law. They believed that this is how they found favor in God and that the sinners and tax collectors could not.
