fzk5220 I hope this helps:
The older brother’s focus was on himself, and as a result there is no joy in his brother’s arrival home. He is so consumed with issues of justice and equity that he fails to see the value of his brother’s repentance and return. He fails to realize that “anyone who claims to be in the light but hates his brother is still in the darkness. Whoever loves his brother lives in the light, and there is nothing in him to make him stumble. But whoever hates his brother is in the darkness; he does not know where he is going, because the darkness has blinded him” (1 John 2:9-11). The older brother allows anger to take root in his heart to the point that he is unable to show compassion towards his brother, and, for that matter he is unable to forgive the perceived sin of his father against him (Genesis 4:5-8). He prefers to nurse his anger rather than enjoy fellowship with his father, brother and the community. He chooses suffering and isolation over restoration and reconciliation (Matthew 5:24, 6:14-15). He sees his brother’s return as a threat to his own inheritance. After all, why should he have to share his portion with a brother who has squandered his? And why hadn’t his father rejoiced in his presence through his faithful years of service?

The wise father seeks to bring restoration by pointing out that all he has is and has always been available for the asking to his obedient son, as it was his portion of the inheritance since the time of the allotment. The older son never utilized the blessings at his disposal (Galatians 5:22; 2 Peter 1:5-8). This is similar to the Pharisees with their religion of good works. They hoped to earn blessings from God and in their obedience merit eternal life (Romans 9:31-33; 10:3). They failed to understand the grace of God and failed to comprehend the meaning of forgiveness. It was, therefore, not what they did that became a stumbling block to their growth but rather what they did not do which alienated them from God (Matthew 23:23-24, Romans 10:4). They were irate when Jesus was receiving and forgiving “unholy” people, failing to see their own need for a Savior. We do not know how this story ended for the oldest son, but we do know that the Pharisees continued to oppose Jesus and separate themselves from His followers. Despite the father’s pleading for them to “come in,” they refused and were the ones who instigated the arrest and crucifixion of Jesus Christ (Matthew 26:59). A tragic ending to a story filled with such hope, mercy, joy, and forgiveness.

The picture of the father receiving the son back into relationship is a picture of how we should respond to repentant sinners as well (1 John 4:20-21; Luke 17:3; Galatians 6:1; James 5:19-20). “All have sinned and fall short of the glory of God” (Romans 3:23). We are included in that “all,” and we must remember that “all our righteous acts are like filthy rags” apart from Christ (Isaiah 64:6; John 15:1-6). It is only by God’s grace that we are saved, not by works that we may boast of (Ephesians 2:9; Romans 9:16; Psalm 51:5). That is the core message of the Parable of the Prodigal Son.

This is one of the all time favorite stories and I fully get the message of the lost being found, but let's face it the older brother was wronged by this father for not showing any pride and gratefulness for his older son's devotion to his father.
Over the years as I read this particular gospel story, I am more and more distracted by the unfairness meted out to the older brother and my mind is less and less drawn to the lost/found emphasis.
Is there or should there be a sequel to this story to provide more balance to the fairness principle?

Book of Micah 7:14-15.18-20.
Shepherd your people with your staff, the flock of your inheritance, That dwells apart in a woodland, in the midst of Carmel. Let them feed in Bashan and Gilead, as in the days of old;
As in the days when you came from the land of Egypt, show us wonderful signs.
Who is there like you, the God who removes guilt and pardons sin for the remnant of his inheritance; Who does not persist in anger forever, but delights rather in clemency,
And will again have compassion on us, treading underfoot our guilt? You will cast into the depths of the sea all our sins;
You will show faithfulness to Jacob, and grace to Abraham, As you have sworn to our fathers from days of old.

Psalms 103(102):1-2.3-4.9-10.11-12.
Bless the LORD, O my soul;
and all my being, bless his holy name.
Bless the LORD, O my soul,
and forget not all his benefits.

He pardons all your iniquities,
he heals all your ills.
He redeems your life from destruction,
he crowns you with kindness and compassion.

He will not always chide,
nor does he keep his wrath forever.
Not according to our sins does he deal with us,
nor does he requite us according to our crimes.

For as the heavens are high above the earth,
so surpassing is his kindness toward those who fear him.
As far as the east is from the west,
so far has he put our transgressions from us.

Holy Gospel of Jesus Christ according to Saint Luke 15:1-3.11-32.
Tax collectors and sinners were all drawing near to listen to Jesus,
but the Pharisees and scribes began to complain, saying, "This man welcomes sinners and eats with them."
So to them he addressed this parable.
Then he said, "A man had two sons,
and the younger son said to his father, 'Father, give me the share of your estate that should come to me.' So the father divided the property between them.
After a few days, the younger son collected all his belongings and set off to a distant country where he squandered his inheritance on a life of dissipation.
When he had freely spent everything, a severe famine struck that country, and he found himself in dire need.
So he hired himself out to one of the local citizens who sent him to his farm to tend the swine.
And he longed to eat his fill of the pods on which the swine fed, but nobody gave him any.
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.
His son said to him, 'Father, I have sinned against heaven and against you; I no longer deserve to be called your son.'
But his father ordered his servants, 'Quickly bring the finest robe and put it on him; put a ring on his finger and sandals on his feet.
Take the fattened calf and slaughter it. Then let us celebrate with a feast,
because this son of mine was dead, and has come to life again; he was lost, and has been found.' Then the celebration began.
Now the older son had been out in the field and, on his way back, as he neared the house, he heard the sound of music and dancing.
He called one of the servants and asked what this might mean.
The servant said to him, 'Your brother has returned and your father has slaughtered the fattened calf because he has him back safe and sound.'
He became angry, and when he refused to enter the house, his father came out and pleaded with him.
He said to his father in reply, 'Look, all these years I served you and not once did I disobey your orders; yet you never gave me even a young goat to feast on with my friends.
But when your son returns who swallowed up your property with prostitutes, for him you slaughter the fattened calf.'
He said to him, 'My son, you are here with me always; everything I have is yours.
But now we must celebrate and rejoice, because your brother was dead and has come to life again; he was lost and has been found.'"
