“In the same way, let your light shine before men, that they may see your good deeds and glorify your Father in heaven.” (Matthew 5:16, BSB) · Read in the Bible
On the way to Capernaum, the disciples argued about which of them was the greatest. Jesus, who knows everything, heard the conversation and answered in a way no one expected: He called an ordinary child and placed the child right in the middle of the circle. There He taught that the greatest in the Kingdom is the one who makes himself the least and serves — and He Himself did that first, when He left the glory of Heaven and went all the way to the cross for us.
Imagine a group of friends walking back from a trip on a dusty road in Galilee. There are thirteen people: Jesus in front, and the twelve disciples behind.
Except that, back there, the conversation got heated.
It was not about food, or about the road. It was about a single question: "which of us is the greatest?" Not the tallest — the most important, number one, the one who would get the best place.
Today's story is in Mark 9 and in Matthew 18. And what Jesus did to answer, no one expected.
I — The argument on the way
"Then they came to Capernaum. While Jesus was in the house, He asked them, “What were you discussing on the way?” But they were silent, for on the way they had been arguing about which of them was the greatest." (Mark 9:33-34)
Notice two things in this scene.
The first: they kept silent. No one answered. Do you know why? Because deep down they already knew that conversation was ugly. We do that too: when a grown-up asks, "what were you doing?", the silence already gives away the answer.
The second: Jesus already knew. He did not need anyone to tell Him. The Bible says that He knew the thoughts of their hearts (Luke 9:47). Jesus is omniscient — which means He knows all things. He knows what we say, He knows what we think, and He knows what we feel inside.
And look at what He did with that. He did not shout, He did not send anyone away, He did not pick someone to blame. "Sitting down, Jesus called the Twelve and said, “If anyone wants to be first, he must be the last of all and the servant of all.”" (Mark 9:35)
He sat down. He called everyone. And He taught.
🏛 Fun fact — what "pride" is. Pride is when a person thinks they are better than others and wants everyone to see it. It shows up in very small ways: laughing at someone who got the answer wrong, bragging, not letting someone else play, getting angry when a classmate is praised. The disciples were good men — and even so, pride got in among them.
II — Jesus puts a child in the middle
Here comes the most surprising part of the whole story.
"Then He had a little child stand among them. Taking the child in His arms, He said to them," (Mark 9:36)
Stop and picture the scene. Twelve grown men, sitting in a circle, arguing about who was the most important. And the Master calls a child who was nearby and puts that child right in the middle of the circle. Then He takes the child in His arms.
The Bible does not tell us that child's name. It does not say whether it was a boy or a girl, it does not say what family the child was from, it says nothing else about the child. It was an ordinary child, like you. And that was the one Jesus chose to be the example.
Then He explained:
"Therefore, whoever humbles himself like this little child is the greatest in the kingdom of heaven." (Matthew 18:4)
And He added a huge sentence: "And whoever welcomes a little child like this in My name welcomes Me." (Matthew 18:5) In other words: whoever welcomes a child in Jesus' name is welcoming Jesus Himself. And Luke records the closing thought: that whoever is the least among them all is the one who will be great (Luke 9:48).
Did you see Jesus' math? It is the opposite of the world's math.
- The world says: the greatest is the one who gets ahead of everyone.
- Jesus says: the greatest is the one who serves.
Being humble is not thinking that you are worthless. It is not going around thinking you are better than others. It is treating everyone with respect — the popular classmate and the quiet classmate, the one who plays well and the one nobody picks.
🏛 Fun fact — children in those days. Today we hear "children first." Back then it was not like that: children had no turn in the circle of adults and hardly ever appeared in stories. That is why the disciples' jaws dropped. Jesus did not choose a soldier, or a rich man, or a teacher of the Law. He chose the person those adults thought did not count.
❤ For the child's heart. Think about how that child felt. The child was just passing by. Suddenly the Son of God calls that child, puts the child in the middle of everyone, and says to the adults: learn from this child. Jesus knew everything about that child — and even so He put the child in the middle. He also knows everything about you.
III — The light that others see
Now put this story together with the verse you are going to keep in your heart today. Jesus had taught, in the Sermon on the Mount:
"You are the light of the world. A city on a hill cannot be hidden. Neither do people light a lamp and put it under a basket. Instead, they set it on a stand, and it gives light to everyone in the house. In the same way, let your light shine before men, that they may see your good deeds and glorify your Father in heaven." (Matthew 5:14-16)
An "oil lamp" is a very old clay light that burned olive oil. A "bushel basket" was a large bowl that could be turned upside down over it. And a "lampstand" is the high place where the lamp was put.
Jesus is saying something simple: light is meant to be seen. Nobody turns on a light and then puts a box over it. You light it and put it up high, so everyone can see the way.
Just notice the very end of the verse, because that is where the secret lives: people see your good works — and then give glory to the Father. The light shines, but the applause goes to God.
That is why being an example is not the same thing as showing off. Someone who shows off is saying, "look how good I am." Someone who is light is saying, without saying a word: "look how good Jesus is."
And if light is seen, the opposite is also true: people copy what we do. Have you ever noticed how a younger brother or sister copies the way the older one talks? We also need to be careful about who we copy — at school, on the street, in the videos we watch. Not everything we see is meant to be copied.
🏛 Fun fact — the lamp does not make its own light. The clay lamp did not invent the flame out of nothing: it needed olive oil and someone to light it. By itself, it was just a little clay pot. It is the exact same way with us. The light does not come from inside us — it comes from Jesus, and our part is not to hide it.
Christ in the Lesson
Here the whole lesson finds its place.
When Jesus put that child in the middle of the circle, He was not just giving advice so the disciples would be more polite. He was showing what He Himself would do.
Think about it: who is the greatest in the whole universe? Jesus. He is the Son of God, the King. And what did He do?
"but emptied Himself, taking the form of a servant, being made in human likeness. And being found in appearance as a man, He humbled Himself and became obedient to death — even death on a cross." (Philippians 2:7-8)
The greatest of all became the least of all. He was born in a manger, inside a stable. He washed His friends' feet, which was a servant's job. And then He went to the cross and died in our place, to pay for our sin. He Himself explained why: He did not come to be served, but to serve (Matthew 20:28).
That is why today's lesson is not "try hard to be the nicest kid." If it were, it would turn into the same argument the disciples had, just with another name — who is the best-behaved kid in the classroom.
The right order is this: first Jesus does something for you; then His life begins to show up in yours. You give your heart to Him, ask forgiveness for your sins, and He forgives you and changes you on the inside. And then the light turns on. It is not your light: it is His, shining through you.
In the last lesson you saw Jesus stopping everything to bless children whom the adults had held back. Today you see the same Jesus taking a child and saying to the adults: this is how one enters My Kingdom.
The King who made Himself small is the King who makes an ordinary child an example for the whole world.
Practical Application
- Serve without being told. The greatest is the servant of all (Mark 9:35). Put away a toy that is not yours, take your brother's or sister's plate to the sink, help Mom without waiting for her to ask twice. Small service done from the heart is great in the Kingdom.
- Do not get into the contest of "who is the best." When the group starts comparing who runs faster, who has more things, who is the most popular, you do not need to join in. And you do not need to fight with anyone over it: just do not go along.
- Invite the one who is left out. Jesus put in the middle the one others thought did not count. Look at the classmate who stays alone at recess and invite them to play. It is the gesture most like Jesus' that exists at school.
- Keep the light up high. Do what is right even when it is hard: tell the truth, do not copy bad behavior, say sorry when you make a mistake. And do not go around asking for praise afterward — the verse says that the one who receives the glory is the Father (Matthew 5:16).
- Be careful who you copy. Not everything that shows up at school, on the street, or on a screen is meant to be copied. Walk close to those who love God, pray, read the Bible, come to church. We become like what we look at all day long.
- If someone hurts you or scares you, tell a trusted adult. If a classmate or anyone else does, says, or asks for something that hurts you, scares you, or has to be kept a secret, you do not have to face that person alone. Tell Dad, Mom, your teacher, or your pastor right away. The adult handles it; the child tells.
Closing Prayer
Dear God, thank You because the Lord Jesus is the greatest of all and even so made Himself the least of all for us — all the way to the cross. Forgive us when pride shows up, when we want to get ahead of others or think we are better than someone else. Put in every child in this class a humble heart that loves to serve. And make our light shine, Lord, not so people will look at us, but so they will look at You. In Jesus' name, amen.
Soli Deo Gloria — Scripture governs; everything else, on its knees.
Frequently asked questions about this lesson
What is the main point of Primary Lesson 10?+
That the greatest in the Kingdom of God is not the one who beats everyone else, but the one who makes himself small and serves. Jesus showed this by putting a child in the middle of the disciples and saying that whoever becomes humble like that child is the greatest in the kingdom of heaven (Matthew 18:4). And the one who did this first was Jesus Himself.
What was that child's name?+
The Bible does not say. We do not know the child's name, or whether it was a boy or a girl, or where the child lived. We only know that the child was right there nearby when Jesus called. And that in itself is wonderful: to become an example for Jesus, you do not need to be famous or be first in line.
Did the disciples really argue? Weren't they Jesus' friends?+
Yes, they were — His twelve closest friends. And even so, they argued on the way about which of them was the greatest (Mark 9:34). When Jesus asked what they had been talking about, they kept quiet because they knew it was wrong. Jesus did not send anyone away: He sat down, called the twelve, and taught them.
Did Jesus know what they were thinking?+
He did. The Bible says that Jesus perceived the thoughts of their hearts (Luke 9:47). He knows everything we say and everything we think. That is not meant to scare us: it is meant to give us confidence. Jesus knows you on the inside and keeps loving you.
Does being an example mean being the best-behaved child in the room?+
It is not a contest over who is the nicest — that would be the same argument the disciples had, just under another name. Being an example means having Jesus in your heart and letting His way show through in your way: helping, telling the truth, and treating everyone well. The strength comes from Him, not from your effort to look better than others.
If I do something good and no one sees it, does it still count?+
It counts, and very much so — God sees everything. Jesus asked that our light shine before others so that they may see our good deeds and glorify our Father in heaven (Matthew 5:16). Notice the ending: people see what we do, but the One who receives the glory is the Father. Doing good to win applause is keeping the glory for yourself; doing good out of love is giving the glory back to God.

Start like this
Arrive early, get the room ready, and welcome each child by name. Quickly revisit last Sunday's challenge: who gave away the paper heart? Listen to two or three stories, thank God for them, and pray with those who did not manage to do it — without pressure and without comparing those who did it with those who did not.
Then open like this: "Who here has ever been playing a game and in the middle of it that argument started: 'I won!', 'no, I won!'?" Let three or four children tell their stories. Usually a board game, a race, or a cousin's video game comes up. Do not let the conversation turn into accusing a classmate; if a name comes up, redirect naturally: "and how did the game end up afterward?"
Then say: "Today's story is about an argument like that. And the ones arguing were Jesus' twelve best friends. Except Jesus heard everything — and His answer turned everything upside down."
Point 1 — The argument on the way
- In the quarterly: the disciples' argument about who was the greatest among them, and the warning about pride and vanity that enter the heart (figure 10.1).
- What to teach: returning to Capernaum, the twelve argued on the way about which of them was the greatest. When Jesus asked, they kept silent — a sign that they already knew it was wrong. And Jesus is omniscient: He knew about the conversation, He knew their thoughts. Even so, He did not humiliate anyone: He sat down, called the twelve, and taught. Make it clear that they were good men who made a mistake that day.
- Anchor verse: "Sitting down, Jesus called the Twelve and said, “If anyone wants to be first, he must be the last of all and the servant of all.”" (Mark 9:35)
- Key question: "Why do you think they stayed quiet when Jesus asked?"
- Likely answers (+ going deeper): "because they were fighting," "because it was ugly," "because they were ashamed." Go deeper: "They stayed quiet because they already knew the answer. Sometimes our silence already gives away what we did."
- If no one speaks: tell your own story first — "when I was a child, I wanted to win at everything, and once..." — and then ask the question again.
Point 2 — Jesus puts a child in the middle
- In the quarterly: Jesus taking a child who was nearby and placing the child beside Him, and the teaching that whoever welcomes that child welcomes Jesus Himself, and whoever welcomes Jesus welcomes the Father (figure 10.2).
- What to teach: Jesus did not answer with a sermon; He answered with a person. He called an ordinary child — the Bible does not even say the child's name — and placed that child in the middle of the circle of twelve adults, taking the child in His arms. There He taught the upside-down math of the Kingdom: the greatest is the one who makes himself humble and serves. Tie this to the honor that child received, without comparing the children in the classroom with one another.
- Anchor verse: "Therefore, whoever humbles himself like this little child is the greatest in the kingdom of heaven." (Matthew 18:4)
- Key question: "Jesus could have called a soldier, a king, or a rich man. Who did He call?"
- Likely answers (+ going deeper): "a child," "a little boy." Go deeper: "And it was not a famous child — the Bible does not even tell us the child's name. For Jesus to use you, you do not need to be first at anything."
- If no one speaks: read Mark 9:36 slowly and ask them to close their eyes and picture the scene: twelve adults sitting down, and a child in the middle, in the Master's arms. Then ask: "how do you think that child felt?"
Point 3 — The light that points to the Father
- In the quarterly: the verse of the day on a poster, the conversation about what light is for, and the teaching that we should do good things everywhere so that people may know the love of God (figures 10.3 and 10.4).
- What to teach: light is meant to be seen — nobody lights a lamp and puts a bowl over it. But read the end of the verse carefully: people see the good works and the glory goes to the Father. Being an example is different from showing off. Take the opportunity to talk about being careful with bad examples that children run into at school and on screens: not everything we see is meant to be copied. Close with Christ here, not with a list of good behavior.
- Anchor verse: "In the same way, let your light shine before men, that they may see your good deeds and glorify your Father in heaven." (Matthew 5:16)
- Key question: "If people see the good things we do, who are they going to praise, according to the verse?"
- Likely answers (+ going deeper): "us," "God," "Jesus." Go deeper on the second and gently correct the first: "That is the key right there. When we do good to get applause, the applause stops with us. When we do it out of love, people look and say: what a good God!"
- If no one speaks: turn on your phone's flashlight, put it on the table, and then turn an opaque cup upside down over it. Ask: "and now, can anyone see the way?" The answer comes by itself.
Class activity
- Goal: to leave the room with a paper lamp in hand that prompts the child to serve during the week — the Essence of the lesson on paper.
- Materials: printer paper, colored pencils or markers, and a flashlight (or a phone flashlight) and an opaque cup for the demonstration. The teacher cuts out the lamps before class.
- Step by step: first do the demonstration with the light and the cup (turn it on, cover it, uncover it) and say the sentence: "light is meant to stay up high." Then hand each child a pre-cut paper lamp with seven rays of light coming out of it. On one side, the child writes or copies the verse — the teacher writes it for those who do not yet write on their own. On the other side, the child colors the lamp and leaves the seven rays blank, only outlined. Explain: each ray will be colored at home, one per day, when the child serves someone. Everyone makes their own, at their own pace, and no one is left without a lamp.
- Wrap-up (back to the text): "Jesus said that the greatest is the one who serves. Each ray you color is a real act of service that you did. And when someone asks why you are helping so much, you already know who to point to: Jesus."
If they ask you this
- Question: "What was that child's name?" Short answer: The Bible does not say. We do not know the name, or whether it was a boy or a girl. And that is wonderful: for Jesus to use someone, that person does not need to be famous.
- Question: "Were the disciples bad people?" Short answer: No. They were friends of Jesus who made a mistake that day. Anyone can make a mistake — and Jesus corrects those He loves and stays with them after the mistake.
- Question: "Is being humble thinking that I am worthless?" Short answer: No. God made you with great value. Being humble is not going around thinking you are better than others and not needing to get ahead of anyone to feel important.
- Question: "If I do something good and nobody sees it, does it count?" Short answer: It counts, because God sees it. The verse says that people see the good works and then give glory to the Father (Matthew 5:16). The good work shows up; the applause belongs to God.
- Question: "So do I have to be the best in the classroom to please Jesus?" Short answer: No — that would be the same contest the disciples had, just with another name. We do not get good first so that we can come to Jesus afterward. We come to Jesus, He forgives us and changes our heart, and then His way begins to show up in ours.
Wrap-up + challenge of the week
- Wrap-up: "Keep today's scene in mind: twelve adults arguing about who was the greatest, and Jesus taking an ordinary child and placing that child in the middle of the circle. The math of the Kingdom is the opposite of the math of the world — the greatest is the one who serves. And the one who served first was Jesus Himself: the King of the universe became a servant, was born in a manger, and died on the cross for our sin. Your light is not yours. It is His, shining from the inside."
- Challenge: this week, serve one person in your home per day, doing a chore that is not yours and that nobody asked you to do — putting away your brother's or sister's toy, taking someone else's plate to the sink, straightening someone's shoes, helping set the table. Each day you serve, color one ray of the lamp you made in class. And do not go around asking for praise. On Sunday, come back with the story.
Teacher's kit
- Before: read Mark 9:33-37, Matthew 18:1-5, and Luke 9:46-48 in full, and set aside figures 10.1 to 10.4. Cut out the paper lamps, one per child, with seven outlined rays, and write the verse on the lamps for the children who do not yet write on their own. Prepare the verse poster and choose two or three songs about serving and about being light.
- Bring: a Bible, the verse poster, the pre-cut lamps, extra colored pencils, a flashlight, and an opaque cup.
- Memory in action: put the poster up in a visible place and read Matthew 5:16 from your Bible; ask everyone to open and read it in their own Bibles too — it is a simple way to teach them to find the verse on their own. Ask beforehand: "what is light for?" and listen carefully. Then play the Mirror Game: pair the class up, facing each other; one makes a slow gesture and the other is the mirror and copies it. Everyone gets to be the mirror at least once, and in each round the class recites the verse aloud together. It is not a competition and there is no winner: if someone gets stuck, do it together with them. Tie it together in one sentence: "there are people copying what we do all day long."
- Quarterly activity: set aside a little time for the activity page — the word search with the virtues of a child who sets a good example, the "mark an X on the correct options," and the free drawing of what we can do to please Jesus. Go over it together, out loud, with the whole class participating.
- Pray beforehand: ask God that no child leaves the room thinking they need to be the best in the class to please Jesus — and that each one leaves knowing that the King of the universe made Himself a servant out of love for them.
Homework
Your mission for the week
Serve one person in your home per day this week, doing a chore that is not yours and that nobody asked you to do: putting away your brother's or sister's toy, taking someone else's plate to the sink, straightening someone's shoes, helping set the table. Each day you serve, color one ray of the lamp you made in class. And do not go around asking anyone for praise.
Why
Jesus answered the disciples' argument with a sentence that turned everything inside out: "Sitting down, Jesus called the Twelve and said, “If anyone wants to be first, he must be the last of all and the servant of all.”" (Mark 9:35) He Himself did that first — the greatest of all made Himself the least for you. Serving is the way His light shows up in your home.
How to know you did it
Look at your lamp: each colored ray is a real act of service. If you can say the person's name and what you did for them, that ray counts.
On Sunday, come back with the story
Bring your lamp and tell us: how many rays you colored, what you did, and what happened afterward. Next class starts with those who did it. Do not stay out.
