The Lost Sheep, Lost Coin, and Prodigal Son (Luke 15)
The tax collectors and sinners are all drawing near to listen to Jesus. The Pharisees and scribes are grumbling. "This man receives sinners," they say, "and eats with them." So Jesus answers their complaint with three stories told back-to-back.
First: a shepherd has one hundred sheep and loses one. He leaves the ninety-nine in the open country and goes looking for the lost one until he finds it. When he does, he carries it home on his shoulders, calls his friends and neighbors together, and throws a party. "There will be more joy in heaven over one sinner who repents than over ninety-nine righteous persons who need no repentance."
Second: a woman has ten silver coins and loses one. She lights a lamp, sweeps the whole house, and searches carefully until she finds it. Then she calls her friends together and says: rejoice with me! The angels of God rejoice over one sinner who repents.
Third, the longest: a man has two sons. The younger one demands his share of the inheritance early, as if his father were already dead. The father divides his property between them. The younger son takes everything, travels to a far country, and squanders it all in reckless living. A severe famine hits. He ends up feeding pigs and so hungry he wishes he could eat what they are eating. He comes to his senses and decides to go home, confess his sin, and ask to be treated as a hired servant rather than a son.
"But while he was still a long way off, his father saw him and felt compassion, and ran and embraced him and kissed him." Before the son can finish his rehearsed speech, the father calls for the best robe, a ring, sandals, and a fatted calf. "For this my son was dead, and is alive again; he was lost, and is found."
But the older son is in the field. When he hears music and dancing and learns what happened, he refuses to go in. He is angry. He tells his father: I have served you all these years and never disobeyed, and you never gave me a party. The father answers: "Son, you are always with me, and everything I have 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." The story ends there. The older son's response is left open.
A Curious Question
The father in the story saw his son coming from far away, ran to meet him, and threw a party before the son even finished apologizing. The older brother, who had stayed home and done everything right, was furious about that party. If you were watching from outside, whose reaction makes more sense to you: the father's or the older brother's? And what does your answer tell you about how you think God feels about people who come back to Him?
Old Testament Connection
The image of God as a shepherd searching for lost sheep runs deep through the Old Testament. Ezekiel 34 is one of the most powerful passages: God rebukes the shepherds of Israel who have failed to seek the lost, strengthen the weak, or bring back the strays. Then He makes a stunning declaration: "I myself will search for my sheep and look after them." God announces that He will do personally what the human shepherds refused to do. Jesus, standing before a crowd of tax collectors and sinners with Pharisees grumbling at the edge, is that fulfillment. He is the shepherd who came looking.
The prodigal son's story also echoes the pattern of the entire Old Testament. Israel repeatedly took what God gave them, wandered into foreign lands of idolatry and sin, came to ruin, and returned. Hosea 14:1 is one of many calls to return: "Return, Israel, to the Lord your God. Your sins have been your downfall." What makes Jesus' parable different is the father's response. He does not wait for a full apology. He does not require the son to prove himself first. He runs. That running father is the heart of the Gospel, grace that moves toward sinners before they have earned the right to be received. It is the same grace that brought Jesus from heaven to the far country of this world to carry us home.
Discussion Questions
- Jesus said the shepherd left ninety-nine sheep to go find one lost one. What does that say about how much God values one person? Does that surprise you? Why or why not?
- The prodigal son rehearsed a speech on the way home. He was going to ask to be treated as a servant, not a son. His father never let him finish it. What does that tell you about how God receives people who come back to Him?
- The older brother was angry that the party was thrown for someone who wasted everything, while he had stayed and worked hard. Have you ever felt like the older brother about someone? What do you think it would take to feel genuinely happy when someone who messed up gets welcomed back?
"So What?" What Can I Do?
This week, think about someone in your life who feels far away: from God, from your family, from your friend group, or from being welcomed somewhere. It might be someone who made a mistake. It might be someone who is different or difficult. Now think about what it would look like for you to be the one who notices them, takes a step toward them, or says something welcoming. You do not have to fix their situation. You just have to be the person who moves toward them instead of looking away. That is what the shepherd did. That is what the father did. That is what Jesus does.
Memorize God's Word
Luke 15:10: "In the same way, I tell you, there is rejoicing in the presence of the angels of God over one sinner who repents."
Hand Motions:
- In the same way, I tell you: Point one finger upward as if making an important point, then bring it down and point it at the person in front of you.
- there is rejoicing in the presence of the angels of God: Raise both arms overhead and wiggle your fingers like falling light, then look upward with a big smile.
- over one sinner who repents: Hold up one finger, then place both hands over your heart and bow your head slightly as if in humble agreement.
Praying with Kids
Father, thank You for being the kind of God who runs toward us. We know we have all wandered in different ways, maybe not to a far country, but away from You in our hearts, in our choices, in the things we have done or left undone. Thank You that when we come back, You do not make us earn our way in. You throw a party. Help us to feel that welcome and to offer it to others this week. And help us not to be like the older brother, standing outside in the cold, keeping score. Bring us in. Amen.
Craft: The Welcome Home Banner
Children will create a small paper banner celebrating the homecoming of someone who was lost. The banner is designed to be taken home as a reminder that God celebrates when any lost person returns and that we are called to join that celebration.
Materials Checklist
Instructions
- Fold the cardstock strip in half lengthwise to create a tent shape that can stand on a table, or keep it flat to hang.
- On the front, write in large letters: "WELCOME HOME." Decorate around the letters with stars, colors, and any celebratory designs the child chooses.
- Below the main text, write the memory verse reference: Luke 15:10.
- On the back, write one name: someone the child would like to pray for this week, someone they know who feels far from God or far from being welcomed. This part is private; they do not have to share the name.
- Punch a hole at each end and thread yarn through to make it a hanging banner, or fold it to stand on a desk or dresser at home.
- Close class by asking: why does heaven celebrate when one lost person comes home? Let children answer before you explain.
Effective Teaching Techniques
Resist the urge to jump to the prodigal son and skip the first two parables. Jesus tells all three together because they build. The sheep parable shows God going out to search. The coin parable shows God searching inside the house. The prodigal son shows God waiting and watching the road. Each parable adds something: the shepherd searches actively in the wilderness, the woman searches actively at home, and the father waits with aching hope. Let children feel the escalation.
The older brother is the moment most teachers either rush through or avoid. Do not. He represents the Pharisees, but he also represents every child who has been well-behaved and wonders if that counts for anything when the "bad kid" gets celebrated. Address it directly: "The older brother felt cheated. Has anyone ever felt that way? Like it is not fair that someone who messed up got treated better than you?" Let children talk. Then ask: "What did the father say to the older brother?" The father came out to him too. He did not abandon the older son. He invited him in. That is the grace extended to the self-righteous as well.
For a dramatic moment: hide something small (a coin, a paper sheep cutout) somewhere in the room before class. At the beginning of the lesson, tell children something is lost. Let them search. When it is found, make a genuine celebration: clap, cheer, make noise. Then say: "That is exactly how heaven feels." The physical experience of searching and finding makes the parable concrete in a way explanation alone never does.
The most likely question: "Is the older brother bad?" The honest answer is: Jesus does not say. The story ends with the father's invitation, not the older brother's response. That open ending is intentional. Jesus is letting the Pharisees decide what they will do with the invitation. That same open ending applies to every child in your room.
