The Prodigal Son Explained: Grace for Sinners and the Self-Righteous
The younger son’s rebellion is easy to recognize: he demanded his inheritance, left home, and wasted what his father gave him. The older son’s resentment can be easier to excuse because he stayed and worked. Jesus brings both sons before us in Luke 15, and I need to read the whole parable to hear His answer to the religious leaders who complained that He received sinners.
The Setting of Luke 15
Then all the tax collectors and the sinners drew near to Him to hear Him. And the Pharisees and scribes complained, saying, "This Man receives sinners and eats with them."
The people drawing near included tax collectors, whose work offered opportunities for exploitation, and others publicly known as sinners. Jesus received them and ate with them without calling their wrongdoing righteous. They were not beyond His mercy or excluded from hearing the truth. The Pharisees and scribes objected to that welcome, so Jesus answered with parables that explain why recovering the lost is a reason for joy.
First, a shepherd searched for a lost sheep and invited others to rejoice when he found it. Then a woman searched carefully for a lost coin and called her friends and neighbors to celebrate its recovery. Jesus explicitly connected both occasions with heaven’s joy over a sinner who repents. The third parable develops that same joy within a family, where one son’s return provokes the other son’s anger.
Prodigal means wastefully extravagant. The traditional title “The Prodigal Son” describes the younger son’s reckless use of his property, but Jesus begins, “A certain man had two sons.” We would miss part of His answer if we stopped reading when the younger son came home. The father who welcomed him also went out to plead with the elder, who would not enter the celebration.
I see the openly sinful people drawing near to Jesus reflected in the younger son, and the resentful religious leaders in the elder. The father’s compassion and joy show how those leaders should have responded. These comparisons help explain Jesus’ answer without making every detail a hidden doctrine. We should not invent a separate spiritual meaning for every possession, piece of clothing, or part of the meal.
The Two Sons and Their Father
Then He said: "A certain man had two sons. And the younger of them said to his father, ‘Father, give me the portion of goods that falls to me.’ So he divided to them his livelihood. And not many days after, the younger son gathered all together, journeyed to a far country, and there wasted his possessions with prodigal living.
The younger son wanted his share before his father’s death. Under the inheritance pattern in Deuteronomy 21:17, the firstborn received a double portion; with two sons, that ordinarily meant two-thirds for the elder and one-third for the younger. The request therefore concerned a substantial part of what sustained the household. Luke’s wording describes the father dividing his livelihood, not handing over a little spending money.
Asking for the property in advance dishonored the father. Popular preaching sometimes expresses the insult as wishing him dead, but Jesus does not put those words in the younger son’s mouth or tell us that this was his deliberate wish. The son wanted the property and chose to leave his father’s company. The division included both sons, with the larger share belonging to the elder.
The younger gathered his possessions, traveled to a far country, and squandered what he had received. Jesus describes reckless living without specifying every expense. Later, the elder accused him of spending the money on prostitutes. That accusation belongs to the angry brother’s speech; we should not repeat it as though Jesus had independently established it.
Once the money was gone, a severe famine struck the country, leaving the younger son in need. He went to work for a citizen of that country, who sent him into the fields to feed pigs. For Jesus’ Jewish hearers, tending animals the Law called unclean underscored how far he had fallen. He wanted to fill himself with the pods the pigs ate, yet no one gave him anything. The son who had left with a share of his father’s wealth was now hungry among another man’s animals.
When he came to himself, he remembered that even his father’s hired workers had bread while he was perishing from hunger. He resolved to return, confess his sin, and ask to be treated as a hired servant. His planned confession named sin against “heaven,” a reverent reference to God, as well as sin before his father. He was admitting that he had wronged both, rather than merely describing a financial mistake or unfortunate circumstances.
He was no longer demanding what he thought was owed to him. He acknowledged his unworthiness to be called a son and got up to go home. His changed thinking led him back to the person he had wronged. That return could neither replace the money nor purchase forgiveness. He came without the means to repair the loss and depended on his father’s mercy.
The Younger Son’s Return
The father saw him while he was still far away, had compassion, and ran to embrace and kiss him. Jesus describes a welcome that began before the son could show a record of improved behavior or earn anything toward repaying the loss. The father received him without first requiring a period of service to prove himself.
"And he arose and came to his father. But when he was still a great way off, his father saw him and had compassion, and ran and fell on his neck and kissed him. And the son said to him, ‘Father, I have sinned against heaven and in your sight, and am no longer worthy to be called your son.’ "But the father said to his servants, ‘Bring out the best robe and put it on him, and put a ring on his hand and sandals on his feet. And bring the fatted calf here and kill it, and let us eat and be merry; for this my son was dead and is alive again; he was lost and is found.’ And they began to be merry.
The son confessed his sin and unworthiness, and the father directed the servants to clothe him and prepare a feast. The whole household could see that he had been welcomed home. He had planned to ask for a hired worker’s place, but his father received him as his son. Compassion restored him to the family without a bargain about wages or repayment.
Some teachers give fixed meanings to the robe, ring, and sandals, treating each as a separate legal declaration about authority or status. Those associations may suggest aspects of the welcome, but Jesus gives no symbolic key for each object. Taken together, the gifts and feast express honor, restoration, and generous joy. We do not need to claim more than the passage supplies.
The feast brings us back to the celebrations over the sheep and coin. The father described his son as dead and now alive again, lost and now found. The separation had been disastrous, and his return gave the household reason to rejoice. They were celebrating the recovery of someone who had acknowledged his sin and come home, without declaring his rebellion harmless.
Those words about death and life belong to Jesus’ illustration of a lost sinner’s restoration. I would not detach them from the parable to teach that a person genuinely born again and sealed by the Spirit can lose eternal salvation and regain it. Jesus is answering the complaint that He welcomes sinners. His answer directs the listeners to rejoice over repentance rather than resent the welcome.
The Older Son and Religious Pride
The elder son came from the field and heard music and dancing. He asked a servant what was happening and learned that his brother had returned safely and his father had killed the fatted calf. Instead of entering, he became angry and refused to go in. The father then came out and pleaded with him.
Here the religious leaders’ complaint appears within the family. Sinners had come near to Jesus, and the Pharisees and scribes objected to His receiving them. The elder likewise knew his brother had returned, yet resented the welcome. He had stayed on the estate and worked, but his father’s joy was something he refused to share.
The elder insisted that he had served for years without ever disobeying a command. That is his assessment of himself, not Jesus declaring him faultless. Even the verb he used for serving can express slaving. He spoke as though he were a laborer whose years of work had earned a reward his father was withholding.
He complained that he had never received even a young goat to celebrate with his friends, while the son who wasted the livelihood received the fatted calf. His objection rested on a comparison of service and reward. He had stayed and worked; his brother had squandered his share. From that calculation, the father’s mercy looked unfair.
The elder distanced himself from the younger by calling him “this son of yours.” He would not acknowledge him as his brother, and he added the accusation about prostitutes. The father answered with “your brother,” reminding the elder of the family relationship he refused to acknowledge. Someone the family had lost was alive and safely home. His recovery was reason to celebrate.
The father continued to address the elder tenderly as “son” or “child.” He reminded him of their life together and of his inheritance in the remaining estate. The earlier division had already included the elder’s share; welcoming the younger did not announce another division. This assurance about the family’s property does not promise material wealth to every Christian. Nor was the father dismissing the elder’s work or denying him a place in the household. He was pleading with him to share the joy of his brother’s return.
His words, “It was right,” explain why the recovery called for celebration. The elder was calculating merit while his father was welcoming a son who had been lost. The elder had remained near his father, but resentment kept him outside a feast he was invited to share.
The father’s appeal helps us hear the mercy in Jesus’ correction of the Pharisees. Jesus exposed their resentment without treating them as people beyond hope. He called them to share God’s joy over the repentant sinners they had despised.
The elder’s complaint exposes the claim self-righteousness can make against God: “I performed, so God owes me.” If I think my obedience has earned His acceptance, another person’s reception of grace can feel like an injustice. The problem is not faithful service. It is treating service as a demand for payment and assuming mercy toward someone else diminishes what I deserve.
Jesus never tells us whether the elder entered. The unresolved ending leaves the Pharisees and scribes facing the response they must make: will they share the joy over repentant sinners or defend their own religious superiority? We face that question too. Knowing Scripture, working faithfully, and maintaining an outwardly respectable life do not by themselves establish that we love the Father.
Grace, Repentance, and the Gospel
The father’s generosity did not remove the need for the younger son to turn homeward. The opening parables explicitly connect heaven’s joy with repentance, and the younger son’s return develops that teaching. He left the course he had chosen, confessed his sin, and came to his father. Repentance is a genuine turning toward God joined to faith, rather than a payment we offer Him.
I would not turn the younger son’s financial ruin into a prediction that every rebel will become poor. Some people can fund their disobedience for years. Jesus shows the damage done when a son values his father’s property more than life with his father. The famine made the younger son’s need impossible to ignore, but hunger alone did not constitute repentance.
That is why I distinguish his repentance from merely regretting the consequences. A person can hate the embarrassment or hardship sin has brought while still defending the sin itself. Judas felt remorse, yet did not turn to Christ for mercy. The younger son named his wrongdoing and returned to his father rather than remaining in despair or rehearsing excuses.
Christ alone saves, and good works follow as evidence of the new life He gives. We should not confuse repentance with making ourselves worthy before approaching Him. The younger son could not restore what he had squandered or demand a son’s honor on the strength of his conduct. His father’s compassion supplied what he could not earn.
Jesus describes the son choosing to rise and return. The father does not force him out of the far country or carry him home against his will; he meets his returning son with compassion. I see grace and a genuine response together here, without the journey or confession making the son worthy of the welcome.
Nor does this parable teach universalism, the belief that everyone will finally be saved. The younger returned, while the elder received a sincere invitation whose outcome Jesus leaves unresolved. An invitation can be genuine even when the hearer refuses to respond. We cannot turn that invitation into a promise that every sinner will enter.
The father’s willingness to go out to both sons also prevents us from restricting mercy to one kind of sinner. Open rebellion needs repentance, and so does self-righteous resentment. Jesus neither excuses the younger’s wastefulness nor condemns faithful obedience in the elder. He confronts the religious pride that claims merit and then objects when another person receives grace.
Jesus Receives Sinners
Luke 15 began with sinners coming to hear Jesus. His welcome allowed them to hear truth that called them to repentance; it did not make exploitation, immorality, greed, or unbelief acceptable. The Pharisees treated distance from such people as a mark of holiness. Jesus sought them in mercy, as a shepherd searches for the lost and a physician comes near the sick to heal them.
A church should therefore speak plainly about sin while making room for people who repent to return. Mercy is not compromise when it welcomes the person God receives. If we refuse that mercy, an orderly religious appearance cannot make our resentment righteous. I need to examine whether I am pleased when a sinner turns to Christ or irritated that the welcome seems more generous than I think the person deserves.
The parable explains the joy of that welcome, while Luke’s account of Jesus’ journey toward Jerusalem shows how forgiveness is secured. Jesus is the eternal Son, fully God, who became fully man through the virgin birth. He lived without sin and willingly gave Himself to be slain as the perfect sacrifice for our sins. Wicked men inflicted real bodily torture and crucified Him. He shed His innocent blood and died for us.
His saving sacrifice through His blood and death was complete before His burial and bodily resurrection. The Father did not punish, curse, abandon, strike, bruise, or pour wrath on Jesus. Father and Son remained united in the work of redemption. Christ died for the sins of the whole world, so every sinner is genuinely invited to repent and believe. People can resist His grace and reject His offer, but the welcome is sincere.
Whoever comes to Christ in repentant faith receives forgiveness and the new birth. The Holy Spirit indwells and seals that believer, who remains eternally secure in Him. Assurance gives no permission for lawlessness, and calling oneself a Christian without evidence of new life does not establish genuine faith. Obedience follows from the life He gives; it neither earns salvation nor keeps us saved. Our salvation rests on Christ’s blood, not on a sinner’s eloquence or the appearance of religious respectability.
If you are defending sin, name it honestly and turn to God through Christ. Do not wait until you imagine you have made yourself worthy, because worthiness is not what you bring. If another person’s repentance irritates you, stop keeping score of what you think you deserve. Grace was never owed to you either. Receive the restored sinner as a brother or sister and share the joy of that restoration.
My Final Thoughts
I do not want to mistake either son’s failure for a right relationship with God. The younger wanted his father’s gifts without his father; the elder treated years of service as a claim against the father whose generosity surrounded him. One came home confessing his sin and received a welcome he could not earn. The other was urged to enter and rejoice over his brother’s recovery. Jesus receives sinners who repent and believe in Him. We should leave our rebellion behind, refuse to make religious service a demand for payment, and gladly welcome those He restores.
