“He also said: “A man had two sons. The younger of them said to his father, ‘Father, give me the share of the estate I have coming to me.’ So he distributed the assets to them. Not many days later, the younger son gathered together all he had and traveled to a distant country, where he squandered his estate in foolish living. After he had spent everything, a severe famine struck that country, and he had nothing. Then he went to work for one of the citizens of that country, who sent him into his fields to feed pigs. He longed to eat his fill from the carob pods the pigs were eating, but no one would give him any. When he came to his senses, he said, ‘How many of my father’s hired hands have more than enough food, and here I am dying of hunger! I’ll get up, go to my father, and say to him, Father, I have sinned against heaven and in your sight. I’m no longer worthy to be called your son. Make me like one of your hired hands.’ So he got up and went to his father. But while the son was still a long way off, his father saw him and was filled with compassion. He ran, threw his arms around his neck, and kissed him. The son said to him, ‘Father, I have sinned against heaven and in your sight. I’m no longer worthy to be called your son.’ “But the father told his slaves, ‘Quick! Bring out the best robe and put it on him; put a ring on his finger and sandals on his feet. Then bring the fattened calf and slaughter it, and let’s celebrate with a feast, because this son of mine was dead and is alive again; he was lost and is found! ’ So they began to celebrate.”
Luke 15:11-24 HCSB
In those days (still today) it was a disgrace to eat with animals especially with pigs; an unclean animal. From having it all to to eating with animals seems like a dramatic step back but this is what happens when you forget how good you had it. In that moment he repents; he had a change of mind. He went back to his father to ask for forgiveness and his father didn’t respond with words but with action. Giving his son his robe, a ring, and a feast to celebrate his return. In this parable it shows that the father cares for all his children even the ones who are lost. When we repent for the sins that we commit God rejoices. He rejoices because we understand that He is a loving God. The beauty in repentance is understanding that God always has your best interest. In the parable when the son comes back some parents would be more mad that the son left them rather filled with joy of the return. Repentance is a change of mind. Whatever we did before we got saved we corrected it by the word of God. When we renew our mind with His word it becomes more clear why we should serve our merciful God.
