The Gospel: Sonship

This passage is perhaps the most foundational text for understanding what it means to be gospel-centered—the very engine on which Metro is built. In verse 1, tax collectors and sinners gather around Jesus, leading the Pharisees to grumble that Jesus is more intimate with sinners than with them. In response, he tells several parables. This—the third—is about a father and two sons. It's been called the Parable of the Prodigal Son, but it's really about two sons. We must unpack it carefully to ensure we don’t miss Jesus’ point.

The Parable

A father has two sons, and the younger asks for his share of the estate—an unthinkable act. In ancient times, a family’s wealth was centralized around the eldest son, who served as the main heir and was responsible for redistributing the land among the family. To ask for your share of the estate was to say, You're taking too long to die. I want your things now. There’s no indication that the father wronged the younger son. He simply wanted his father’s things more than he wanted his father. Now, parables are short stories with punchlines that would have shocked the original listeners and lessons flowing out of those shocks. If you were listening in Jesus' time, you'd have been appalled—the son should have been beaten or disowned. In an agrarian culture where your land was your life, the younger son is asking the father to tear his life apart. But astonishingly, the father honors the request. The Greek literally says he divided his bios—his life.

In verse 13, the younger son leaves for a distant country and wastes everything through wild living. A famine hits, and in the mud with the pigs, he finally “[comes] to his senses” and plans a script to get back home. Then comes another shock: the father sees his son from far off and runs to him. A father in those times would never run—it was undignified to pick up your cloak and bare your legs. But he doesn't care. He runs, embraces his son, and kisses him. The son begins his script but is cut off: Quick, get him the best robe! Get him a ring and sandals! We'll have a feast tonight! When you lose your treasure and find it again, it's the greatest day of your life.

Now comes the elder son. He hears the music, learns his brother has received the fattened calf—the most expensive meal in a culture where meat was a rare delicacy—and is furious: I never even got a goat, and you give him this? In verse 29, the Greek implies he's practically grabbing his father by the collar. Why? Because in his mind, this is his money. He completely misses his father's heart. Growing up, many of us thought the lesson was to be like the older son instead of the younger son. But we see here that the older son also cares more about the father's things than the father himself. But look at the father. The elder brother refuses to go inside, so the father comes out and pleads with him: Everything I have is yours. That’s where the parable ends—open-ended.

Lessons from the Parable

First, this parable shapes our view of God. We're often taught to view God as Almighty Creator and King—which he is. Perhaps we've come to fear him. But look at this father who gives and gives, enduring betrayal and humiliation despite being a man of power. Jesus is revealing both the kingliness and the humility of God. He melts into his younger son's arms, having lost all strength in the emotion of the moment—and then subjects himself to further humiliation to plead with the elder son. No one had ever described God like that in those ancient times. Even today, no other religion could imagine a God like that.

Second, this parable redefines our view of sin and lostness. It’s only when we look at both sons together that we see a much more accurate view of sin. In the younger son, we see a traditional, self-indulgent picture of sin. He bought into the lies of society and came back naked and ruined. Conversely, the elder son obeyed the father and stayed home. But when he learns about the fattened calf being killed, his true heart is exposed. The younger son was lost because he was running away from the father, but the elder son was lost because of his goodness—a veil covering a deep-rooted selfishness that surfaces when he doesn't get what he wants. All he can see is what’s owed to him being wasted: I’ve been slaving for you. And what do I get for it? He actually thinks of himself more as a slave than a son.

“Younger son sin” will bankrupt you until you are alone and ruined—it’s an overt lostness. But “elder son sin” is a slow, covert death—that’s what makes it dangerous. It will enslave you, making you work for the approval of God—and those around you—until the anxiety and fatigue leave you similarly alone and ruined. The irony is that the “bad” son made it back to the house and received the celebration, but we're never told what happened to the “good” son. The gospel isn’t the balanced midpoint between these two lifestyles—Jesus is saying both sons are distant from the father.

Third, this parable gives us a new view of repentance. The younger son gets the robe, the ring, the sandals, the feast. Why? Because of the pivotal moment in verse 17: he came to his senses. That phrase is a Hebrew idiom representing repentance. He woke up to his sin—not just the overt acts, but the fact that he’d been looking for a home apart from his father. At one point, he’s longing to eat the pods the pigs ate, showing that sin always promises to make you more human but ends up making you less. How do you become more human again? You have to come to your senses. How? The famine. Your plans get completely derailed, leaving you disoriented and alone. But the son needed that to realize, I'm a son. That's my father. Even though the father had already been loving, the son accesses that love through repentance—coming to his senses and returning home.

Repentance isn't trying to atone for your sins by your own efforts. This reduces sin to a mere violation of rules where a self-induced penalty can eventually make things right. That only leads to self-pity and exhaustion. Repentance isn’t a change in behavior where you rebrand yourself to look humble or changed. Repentance isn’t concluding that the damage is irreparable and that you need a new life—a new spouse, job, or church—blaming others and making excuses. In all three cases, you’re still clinging to your own ability to make things right. Real repentance connects us to the only true source of power: the love of the Father.

The younger brother's plan is essentially to become more like his brother, but as we've seen, that's its own kind of lostness. Obedience isn’t the problem—the gospel is not less than obedience; it's far more. The problem is that the elder brother was only obedient because he wanted something apart from his father. His heart was already far away.

Question 1A:
It wasn’t until the famine hit that the younger son “came to his senses.” What "famines" has God used to bring you to your senses? What did you learn through that experience?

Question 1B:
We tend to see ourselves in one son. But could the other one reveal more about you than you might assume?

Finally, this parable gives us a new view of the grace of God. The younger brother says, “Father, I have sinned against heaven and against you. I am no longer worthy to be called your son.” It's all true—but repentance isn’t what earns God's love; it merely accesses a door the Father has already opened. Repentance is about who is going to save you: either Jesus or you. You can repent of the bad things you do, but repentance requires first letting go of your need to save yourself. The younger son once believed that “home” was the fulfillment of his desires, but he now sees that it’s the embrace of his father. Look at the father rushing to embrace and kiss his son who has barely repented. As Tim Keller says, repentance doesn't trigger the kiss; it's the kiss that triggers the repentance. You just need to come home. Even the elder son who just humiliated him still receives a plea: Come inside! It's left open-ended, Jesus' way of saying to the religious: You might be even more lost than your brother—but you can still come home too.

But look at the great cost of bringing the younger son in. When someone sins against you, an apology isn’t sufficient. There's a debt that needs to be paid—and the elder son is angry because he doesn't want to pay it. The father spares no expense in welcoming his brother back. But whose robe was it? Whose ring and sandals? Whose fattened calf? When the father tells the elder son, “Everything I have is yours,” that's literally true, because everything that remains belongs to the elder son—all of this is coming at his cost. That's the cost of sin. The elder son is so mad that he won’t even refer to the younger son as his brother: “This son of yours.” Why does Jesus give us this terrible picture of an elder brother? So that we would long for a better one. The truth is that we’re all younger sons and elder sons who need a true elder brother who is willing to leave home—not to get away from his father but to fulfill his wishes because he knows the father’s heart. He’d risk everything to bring his brother home.

The younger son didn't have a brother like that. But the beauty of the parable is that we do. Hebrews 2 says that Jesus is “not ashamed to call [us] brothers.” He didn’t just leave an earthly estate to save his people—he left his Father's throne. He stepped into the darkness and famine to bring us home, sacrificing not just a robe or sandals but his power and glory. 2 Corinthians 5 says that “God made him who had no sin to be sin for us, so that in him we might become the righteousness of God.” On the cross he cries, “My God, my God, why have you forsaken me?” as he experiences the ultimate famine and bankruptcy. The younger son arrived home practically naked; Jesus was stripped naked for us. The younger son received the ring of honor; Jesus received the crown of thorns—the ultimate dishonor. Both sons received loving invitations. But on the cross, Jesus is completely isolated—the one time in Scripture he doesn’t refer to God as Father—and yet Isaiah 53 says he was satisfied at the justification of many.

Jesus chose to have his heart torn apart on the cross so that we could become sons. Everything is a famine compared to knowing him. It's his kindness that leads us to repentance. There’s nothing more beautiful than the Father and Son longing for us—and nothing more incredible than their joy when we come home. So let’s come to our senses today.
