Lost & Found

Luke 15

Over the last few weeks we have been talking about the Gospel — what it is, why it matters, and why every follower of Jesus is called to share it. Tonight we continue that conversation by looking at one of the best-known chapters in Scripture: Luke 15.

When we hear the word lost, we usually think about how someone became lost. We lose our keys. We take a wrong turn. In the church, we often use the phrase "the lost" to describe people who do not yet know Jesus.

But being lost is more than being in the wrong place. It means being separated from where we belong—the way a lost child is separated from their family, or a lost sheep from its shepherd.

Some people drift. Some openly rebel. Some are deceived. Others appear close to God outwardly while remaining far from Him inwardly.

Lostness may look different from one person to another, but it always separates us from the Father. (Isaiah 59:2; Ephesians 2:12–13)

However we get there, the condition is the same. We are separated from the One we were created to know.

Luke 15 helps us understand what it means to be lost — but more importantly, it reveals the heart of God toward those who are lost.

Read Luke 15.

Luke tells us why Jesus told these parables. Tax collectors and sinners were gathering to hear Him — tax collectors despised for growing rich off their own people on Rome's behalf, "sinners" a broad label the Pharisees pinned on anyone who didn't meet their standard. These were people respectable religion kept at a distance. (Luke 15:1)

But Jesus did not. He welcomed them. He ate with them. (Luke 15:2)

Sharing a meal in that culture was an expression of fellowship and welcome. Jesus was not approving of their sin; He was showing that their sin did not place them beyond the reach of God's grace. (Luke 5:29-32; Luke 19:7-10)

That is what offended the Pharisees. They grumbled, "This man receives sinners and eats with them." (Luke 15:2) If Jesus truly came from God, why would He associate with sinners?

Jesus does not argue with them. He tells three parables. (Luke 15:3-32) Each shows us another aspect of what it means to be lost, and each reveals something about the heart of God. Together they act like a mirror — inviting us to recognize ourselves somewhere within them.

Jesus begins with a shepherd. "What man among you, having a hundred sheep, if he has lost one of them, does not leave the ninety-nine in the open country and go after the one that is lost until he finds it?" (Luke 15:4)

We've heard this story so often it's easy to picture a gentle shepherd carrying a fluffy lamb and miss the danger. Sheep are not well-equipped to survive alone — not fast, not strong, with few natural defences. Once separated from the flock, a sheep is vulnerable to predators, injury, hunger, exposure. The shepherd leads it to food, protects it from danger, cares for it when injured. Everything the sheep needs is found in its relationship with the shepherd. Separated from him, it is in danger. (Psalm 23:1-4; John 10:11-14)

That is the first thing Jesus shows us about spiritual lostness: being separated from God is not merely unfortunate. It is dangerous, because we were never created to live apart from Him. (John 15:5-6)

Jesus does not tell us how the sheep became lost, because that isn't the point. The point is that it is separated from the shepherd and cannot find its way home. The tragedy of sin is not simply that it makes us guilty, though it does — sin separates us from the God who gives us life. When that relationship breaks, everything else unravels. (Genesis 3:8-10; Isaiah 59:2; Romans 6:23)

But the sheep isn't the main focus of the story. The shepherd is. He goes after it until he finds it — no quick search, no settling for ninety-nine being good enough. And when he finds it, he doesn't scold it or drive it home with a stick. He lifts it onto his shoulders and carries it back, rejoicing. (Luke 15:4-6)

That is the heart of God. The Pharisees believed holiness meant keeping sinners at a distance. Jesus tells them they've misunderstood His Father. God is not indifferent toward those far from Him — He is the Shepherd who seeks His sheep and carries them home. (Ezekiel 34:11-16; Luke 19:10; John 10:11)

Then a second story. A woman has ten silver coins and loses one. Unlike the sheep, the coin hasn't wandered away — it has no ability to move, cannot cry out, cannot decide to return home. (Luke 15:8) It is completely helpless.

Jesus is showing us another aspect of lostness: not only are we in danger when separated from God, we are unable to rescue ourselves. (Ephesians 2:1-5)

That's hard for us to accept, because we value independence and self-improvement — we like to believe that if we try hard enough, we can fix almost anything. The Gospel tells us we cannot save ourselves. (Ephesians 2:8-9; Titus 3:5)

Salvation does not begin with us climbing our way back to God. It begins with God moving toward us. (Romans 3:10-12; Romans 5:8; 1 John 4:10)

The woman lights a lamp, sweeps the house, and searches diligently until the coin is found. Its value hasn't changed because it's hidden in the dust. (Luke 15:8-9)

The same is true of every person. The sheep was still valuable when it wandered, the coin was still valuable in the darkness, and the younger son was still loved after wasting everything. Their value had not disappeared, but while they remained lost, they were separated from where they belonged. In the same way, every person bears God-given worth, but we cannot experience the life, relationship, and purpose for which we were created while remaining separated from the Father. (Genesis 1:26–27; Luke 15:20–24; John 15:4–5; Ephesians 2:10, 12–13)

People matter to God. (Matthew 10:29-31)

That is why Jesus receives sinners — not because sin is insignificant, but because people are precious to Him. (Luke 15:2; Romans 5:8)

One more detail: the woman lights a lamp to search the darkness. (Luke 15:8)

The lamp also reminds us of what Jesus says elsewhere: "You are the light of the world." (Matthew 5:14)

We don't save people; Christ is the Saviour, and the Spirit opens blind eyes. But God has chosen to shine the light of Christ through His people. (John 4:42; 2 Corinthians 4:4-6)

We speak the truth about Jesus, love our neighbours, and point people toward the One who saves. (Matthew 5:14-16; Acts 1:8; 1 Peter 2:9)

The woman doesn't light the lamp and sit down hoping the coin finds itself — she carries the light into the darkness and searches. The church cannot be satisfied enjoying the light inside its own walls; Jesus sends us into our homes, workplaces, and neighbourhoods, trusting the Spirit to use our witness. (Matthew 28:19-20; Acts 1:8)

Then Jesus tells His third and longest story. A man has two sons. The younger asks for his share of the inheritance while his father is still alive — an astonishing insult. In effect: "I want what belongs to you, but not you. I'd rather have your possessions than your presence." (Luke 15:11-12)

At its heart, that is what sin has always been — wanting God's gifts without wanting God Himself. (Romans 1:21-25) Amazingly, the father gives the son what he asks for. (Luke 15:12)

The son wastes everything in a distant country. A famine comes, the friends disappear, and the freedom he wanted becomes slavery — he ends up feeding pigs, longing to eat their food. (Luke 15:13-16)

For Jesus' Jewish audience, this was the lowest situation imaginable. (Leviticus 11:7-8; Luke 15:15-16)

That is what sin does: it promises freedom but produces bondage, promises life but leads toward death. (John 8:34; Romans 6:21-23; James 1:14-15)

Then Jesus says, "He came to himself." (Luke 15:17) The fog lifts. He remembers his father's house, where even the servants have more than enough food. He decides to go home, rehearsing a confession: "Father, I have sinned against heaven and before you. I am no longer worthy to be called your son." (Luke 15:17-19)

He doesn't blame the famine, his friends, or his father. He recognizes his sin and turns around.

That is repentance — not merely feeling sorry, but recognizing we've been walking away from God, that we are lost and then turning around, and returning to the Father. (Isaiah 55:6-7; Acts 3:19; 2 Corinthians 7:10)

The first two stories emphasize God's initiative; here we see the human response. But we don't repent to convince God to start loving us — we turn toward the God who has already moved toward us. (Romans 2:4; Romans 5:8; 1 John 4:19)

While the son is still a long way off, his father sees him. (Luke 15:20) The father is filled with compassion. He runs to his son, embraces him, kisses him. Before the son can finish his prepared speech, the father calls for the best robe, a ring, sandals, the fattened calf: "This my son was dead, and is alive again; he was lost, and is found." (Luke 15:20-24)

That is grace. The son deserved judgment but received mercy. He expected to become a servant but was restored as a son with all the rights and responsibilities and privileges and authority that goes with it. He came home hoping to earn a place in the household, but the father welcomed him back into the family. (Luke 15:19-24)

Justice means sin must be judged. Mercy means we are not given the judgment we deserve. Grace means we are given what we could never earn. (Romans 3:23-24; Ephesians 2:4-9)

But God does not set aside justice to show mercy — at the cross, Jesus bore the judgment our sin deserved, so that God remains perfectly just and still welcomes sinners home. (Isaiah 53:4-6; Romans 3:25-26; 2 Corinthians 5:21; 1 Peter 2:24)

The cross proves how serious sin is — and how great the love of God is. Jesus took our judgment so we could receive mercy, forgiveness, and a place in the Father's house. (Romans 5:8-9; Colossians 1:19-22; 1 Peter 3:18)

The father does not call the son's rebellion good — he says his son was dead and lost. But grace declares that the father's love is greater than the son's failure. (Luke 15:24; Romans 5:20-21)

Then the celebration begins — and this celebration is one of the main points of the whole chapter. Jesus repeats it in each parable. (Luke 15:6-7, 9-10, 23-24) The shepherd finds the sheep, and there is rejoicing. The woman finds the coin, and there is rejoicing. The father receives his son, and there is a feast. Heaven rejoices when one sinner repents. (Luke 15:7, 10)

Repentance is not met with reluctance in heaven, or with folded arms and suspicion. Heaven celebrates because someone who was dead is alive, and someone who was lost has been found. (Luke 15:7, 10, 24)

But Jesus isn't finished. The older brother comes in from the field, hears music and dancing, and refuses to go inside when he learns his brother has returned. (Luke 15:25-28)

At the start of the chapter, the Pharisees refused to share the table because sinners were there. Now the older brother refuses to enter the celebration because his sinful brother is there. Jesus has brought the Pharisees into the story. (Luke 15:2, 28)

The older brother reminds his father, "These many years I have served you, and I never disobeyed your command." He sees himself as a servant, not a son. (Luke 15:29-30)

That is the great surprise of Luke 15: a person can remain close to the things of God while still being far from God. We can attend church, serve faithfully, know the Scriptures — and still trust our performance instead of His grace. (Matthew 15:7-8; Philippians 3:4-9)

The older brother believed his years of obedience had placed his father in his debt; he viewed his service as something owed to him rather than his father's presence as a gift to enjoy. (Luke 15:29)

Self-righteousness makes grace offensive — it causes us to compare ourselves with others and believe we deserve more from God than they do. (Luke 18:9-14; Romans 10:3-4)

The younger brother knew he needed mercy. The older believed he had earned favour. Both were lost.

But notice what the father does: he goes out to both sons. He runs to meet the younger, and he leaves the celebration to plead with the older. One needs to be rescued from rebellion. The other needs to be rescued from self-righteousness. (Luke 15:20, 28)

"Son, you are always with me, and all that is mine is yours. It was fitting to celebrate and be glad, for this your brother was dead, and is alive; he was lost, and is found." (Luke 15:31-32)

And there the story ends. Jesus never tells us whether the older brother goes in. He leaves it unfinished because the older brother is standing in front of Him. The Pharisees must decide whether they will remain outside, grumbling, or humble themselves and enter the Father's joy. (Luke 15:1-3, 28-32)

There is a pattern running through all three parables: something is lost, someone searches, what was lost is found, and there is rejoicing. (Luke 15:4-7, 8-10, 11-32) That pattern reveals the heart of God. The shepherd seeks. The woman searches. The father runs and pleads. (Luke 15:4, 8, 20, 28)

So let me leave you with this.

Jesus tells parables to show us something of homself and his Kingdom and also as a mirror for us.

We can find ourselves lost by wandering away, maybe through the circumstances of life we don’t even know where the shepherd is, or maybe re ran away in anger or frustration.

Jesus knows.

He has not forgotten you. He is the Good Shepherd who came to seek and to save the lost. The Shepherd is still seeking.

We do not have to earn our way back. You simply need to turn to Jesus who has already come looking for you.

And if you have already been found, then this chapter becomes our calling.

We are called to follow our Shepherd and to have His heart towards the lost. We are called to love what He loves and rejoice over what brings joy to heaven. We are called to carry the light of Christ into the dark places of our world and to eagerly join Jesus in His mission of seeking the lost.
