Object lessons with tiny plastic landmines, I mean, LEGO bricks
True Fact: Walking on LEGO bricks Hurts More Than Walking on Hot Coals or Broken Glass.
Seriously. According to science. (Source: Click here to read the article in Smithsonian magazine.)
But, here’s a thought: What if these tiny plastic landmines could become one of our best tools for discipleship?
What if LEGO bricks weren’t just something kids build with before class, but a metaphor for what God is doing in them?
In this article, I want to show you how to turn a bucket of bricks into a long-term strategy for teaching Biblical truths, not just a one-off “wow” moment.
We’ll get practical: I’ll walk through five LEGO Bible object lessons you can use in Sunday school, kids church, or even family devos.
But first, we’ll get philosophical: We’ll zoom out to see how the LEGO bricks can fit into big-picture, theological discipleship.
We'll look at how to use object lessons with LEGO bricks without dumbing down theology, and how to build kids’ faith brick by brick over time.
So let’s dump the LEGO tub on the floor and start sorting.
First, a Roadmap to Show You Where We're Going
(Scroll down for more detailed explanations, including 5 LEGO Bible Object Lessons You Can Do with Any Bucket of Bricks.)
Why Bible Object Lessons Work (and Why Kids Remember Them)
If you’ve been in children’s ministry longer than a week, you already know this: Bible object lessons can be powerful.
Why?
Because our kids live in a world of screens, stories, and stuff. They don’t just see and hear the world; they touch it, build it, wear it, and meme it. When you take everyday items and use them to teach, something clicks.
Object lessons do at least three really important things:
1. THEY HOOK ATTENTION
You know that moment when kids walk in and see something weird on the table? A giant balloon, a pile of junk food, a bucket of LEGO bricks… and their eyes light up?
That’s gold.
A good object lesson says, without words:
“Something interesting is about to happen. You should pay attention.”
2. THEY GIVE KIDS A HANDLE
Kids don’t just need words; they need handles – mental pictures they can hang those words on.
o “Build your life on Jesus” is abstract.
o Watching a LEGO tower wobble on a flimsy base and crash? Concrete.
Later in the week, when something in their life wobbles, that picture quietly comes back:
“Oh yeah… foundations matter.”
3. THEY CREATE SHARED LANGUAGE
When you use the same kinds of Bible object lessons again and again, you create a shared vocabulary in your group.
“Remember the rope that broke and got tied back together?”
“Remember the dirty water that got cleaned?”
“Remember the LEGO tower that fell down?”
Those become shorthand for deeper Biblical truths.
So yes, Bible object lessons really do help kids remember. But here’s the key shift I want us to make:
Object lessons shouldn’t be one-offs that add a little pizzazz to today’s lesson but are quickly forgotten tomorrow.
Instead, they should be used regularly, tied together, scaffolding each other, until they become part of a long-term discipleship plan, helping children gradually build a Biblical worldview over months and years.
And that’s where LEGO bricks really shine.
Why LEGO bricks Are the Perfect Tool for Teaching the Bible
I’ve tried a lot of props over the years. Eggs. Alka-Seltzer tablets. Fire demos. (All are very cool, by the way.)
But LEGO bricks are special.
Here’s why object lessons with LEGO bricks are such a powerful tool to teach children:
1. LEGO bricks are naturally about building
The Bible is full of building imagery: houses on rock and sand, temples, walls, foundations, living stones, the body of Christ being “built up.”
When kids build with bricks, you have a ready-made metaphor for:
o Growth
o Process
o Design and purpose
o Foundations
o Being joined together
2. LEGO bricks are reusable and indestructible
You don’t burn them, crack them, or smash them beyond repair. (Well… usually.)
You can use the same tub of bricks to teach:
o Salvation (a brand-new foundation)
o Sanctification (God building us up over time)
o The church (many pieces, one body)
o Spiritual gifts (many pieces, different uses for each)
o Perseverance through difficulty (towers fall, designs don’t pan out, keep trying)
That repeatability is huge. The more often you use LEGO bricks in your Sunday school object lessons, the more they become a visual framework for theology.
3. LEGO bricks work across ages
o K–1 can use Duplos and simple builds.
o 2–3 graders can follow basic challenges.
o 4–5 graders (including the “too cool” boys) can handle complex builds, timed challenges, and deeper reflection.
Same object, different depth. That’s exactly what you want when you’re teaching Biblical truths in a mixed-age ministry.
When you keep coming back to LEGO bricks, you’re not just teaching one lesson – you’re giving kids a repeatable picture of how God works: patiently, purposefully, piece by piece.
Now let’s get practical. Keep reading below this short plug for the Spyence newsletter.

5 LEGO Bible Object Lessons You Can Do with Any Bucket of Bricks
Here are five LEGO Bible object lessons you can do with any random assortment of bricks you can scrounge from your kids’ rooms or the church closet.
Each lesson:
• Connects to a specific Bible passage
• Supports a bigger theological category
• Includes ideas for K–1, 2–3, and 4–5
• Helps build long-term discipleship, not just a one-time “wow”
1. Building on the Rock vs. Sand
Big Idea:
Build your life on Jesus’ words, not just your own ideas.
Passage:
Matthew 7:24–27 (The wise and foolish builders)
What you need:
• LEGO bricks or Duplos
• A solid base (table, tray, or big baseplate)
• A “wobbly” base (pillow, folded blanket, or something you can gently shake)
Activity:
1. Divide kids into groups.
2. Ask each group to build the tallest tower they can in 3–5 minutes.
3. When time is up, ask each group to test their tower during a “storm”:
o Place their tower on the wobbly base and gently shake the wobbly base.
o Then place their tower on the solid base and lightly bump or blow on the solid base.
Ask:
• “What happened to each tower?”
• “Which one stayed standing?”
• “Why?”
• “In real life, what do you think it means to build your life on something solid… or something wobbly?”
Connect:
Read Matthew 7:24–27, then say something like:
“Jesus says that listening to His words and actually doing them is like building your house on a rock. It doesn’t mean storms never come. It means that when they do, your life doesn’t fall apart. You’re held by Him.”
Long-term discipleship angle:
Week 1 of a series, this object lesson becomes the foundation (pun fully intended).
Later, when you talk about growth or trials, you can point back:
“Remember that tower that fell over? That’s what it’s like when we try to live without Jesus as our foundation.”
Age adaptations:
• K–1: Help them build together as one big tower. Keep your language simple.
“Who is our rock?” “JESUS!”
• 2–3: Let them build in groups and share what they noticed.
• 4–5: Add real-life questions:
“What’s a ‘wobbly’ choice you see kids your age make?”
“What would it look like to build on Jesus instead?”
Theology guardrail:
Avoid implying, “If you trust Jesus, nothing bad will happen.”
Instead, emphasize, “Bad things may happen. Storms may still come. But when they do, Jesus goes through them with you. He’s always there and always loving you.”
2. The Body of Christ (Many Pieces, One Build)
Big Idea:
The church is made up of many different people with different gifts, joined together in Jesus.
Passage:
1 Corinthians 12:4-27
What you need:
• A mixed pile of LEGO bricks
• Enough bricks for each child or team to have a handful
Activity:
1. Divide kids into small teams.
2. Give each team a different mix of pieces:
o One team gets mostly flat baseplates
o One team gets mostly standard bricks
o One gets lots of windows/doors
o One gets a collection of minifigs
3. Tell each team to build a church scene.
4. Give them a few minutes to realize they can’t do it separately.
5. Then give them some time to bring all their pieces together into one larger creation.
Ask:
• “What would happen if one team refused to join the big group project?”
• “Were some pieces ‘cooler’ than others? Did you still need the ‘boring’ pieces?”
• “How is this like the church?”
Connect:
“The Bible says we’re like parts of one body. We’re not supposed to be exactly the same. God gives each of us different gifts – different ways to serve – so that together we can show the world what Jesus is like.”
Long-term discipleship angle:
This LEGO Bible object lesson helps you build the category of church and spiritual gifts:
• You’re helping kids learn: “I have a place. I’m needed. God created me with unique gifts, talents, and skill. I don’t have to be like everyone else to matter.”
Age adaptations:
• K–1: Build one simple tower together, and just emphasize, “We need each other. God loves to put us together.”
• 2–3: Have them share what they like about each other’s contributions to the build.
• 4–5: Get more specific:
“What gifts do you see in our group? Who encourages others? Who serves quietly? Who loves to pray?”
Theology guardrail:
Avoid implying that “important” roles (on stage, up front) are more valuable. Emphasize: “In a body, we need hearts and hands and toes and lungs. You may not see every part, but every part matters.”
Dive deeper: this Spyence Unit includes 6 full lessons on the church – helping kids understand that they need the fellowship, worship, and training that only comes from a local church family, and that their local church family needs them to exercise their spiritual gifts to build others up.
3. God’s Rescue Plan (Justification & Sanctification)
Big Idea:
God doesn’t just forgive us our sins and adopt us into His family (justification). He has plans to grow us into new people who love Him and reflect His nature in the world (sanctification).
Passage:
Ephesians 2:1–10
What you need:
• A pile of LEGO bricks
• A wonky, shaky, pre-built structure (you can build this beforehand to look random and unstable)
• A simple design or picture you plan to build instead
Activity:
1. Show the wonky structure. Ask: “Do you think I followed the build instructions when I put this together?”
2. Explain that, similar to how I didn’t follow the instructions when I put this together, sin is “missing the mark,” or not following God’s instructions for our lives. And how sin breaks our relationship with God. That’s why we need forgiveness and new life through faith in Jesus.
3. But… God has even bigger plans for us than that. He wants to grow us into spiritually mature people.
4. Then, carefully take apart the wonky structure and rebuild it together according to the plan, as an example of the process of sanctification
Ask:
• “How do you feel about this new structure compared to the old one?”
• “Was it easy or hard, quick or slow, making improvements? Could we improve the structure even further?”
• “How is that like our lives?”
Explain:
“The Bible says that on our own, we’re like that wonky, shaky, messy build. We try to fix ourselves, but our hearts are still broken by sin. God didn’t just send us a self-help book. He sent Jesus. When we trust Him, God gives us a brand-new start. And not only that, He begins building something beautiful in us.”
Now bring in justification vs sanctification in kid-friendly language:
• Justification: “When you trust Jesus, God gives you a brand-new foundation. He says, ‘You belong to Me. You’re forgiven. You’re in My family.’ That happens once, forever.”
• Sanctification: “After that, God spends the rest of your life building – adding bricks of love, patience, courage, kindness. Sometimes, He even takes apart a wobbly part so He can rebuild it stronger. That’s Him growing you.”
Long-term discipleship angle:
Over time, this LEGO image helps kids distinguish:
• Being saved once for all (new foundation, new start)
• Being changed gradually (growth brick by brick)
Age adaptations:
• K–1: Simplify: “Jesus gives us a new start.”
• 2–3: Introduce the idea of God “still working on us.”
• 4–5: Use the words justification (new foundation) and sanctification (building over time) and let them try them on. Kids can handle more theology than we think.
Theology guardrail:
Don’t promise: “If you become a Christian, all your problems go away.”
Emphasize instead: “Life can still be hard. We still make mistakes. But now we belong to Jesus, and He promises He will finish the good work He started in us.”
Dive deeper: this Spyence Unit includes 6 full lessons on justification and sanctification.
By the end of this unit, kids will know that…
- When they believe in Jesus, God adopts them into His family.
- As they obey His commands, they grow to be more like Him.
- They can look forward to eternity on the New Earth—serving, worshiping, and enjoying God forever.
4. Prayer and Perseverance (Keep Building!)
Big Idea:
We keep coming back to God again and again as He grows us.
Passage:
Luke 11:5–10
What you need:
• LEGO bricks
• A timer (phone, clock, or a kid who loves to count loudly)
Activity:
1. Round 1:
“You have 2 minutes to build the tallest tower you can. Go!”
2. When time is up, stop them and talk:
o “What worked? What didn’t?”
o “Where did it start to get shaky?”
3. Round 2:
“Now that you’ve seen what went wrong, you have 2 more minutes to build again. This time, make it stronger.”
Ask:
• “What did you change the second time?”
• “Why was the second tower better?”
• “How is following Jesus a lot like that – learning, trying again, asking God for help?”
Explain:
“When we pray, we’re not just sending God a text once and walking away. We keep coming back. We keep talking to Him as He works in us.”
Long-term discipleship angle:
This LEGO Bible object lesson reinforces perseverance in prayer:
You’re teaching kids: “God doesn’t always answer our prayers immediately (for example, when He knows the timing isn’t right yet). He always knows what’s best for us. We need to trust Him, keep talking to Him, and keep waiting for His answers.”
Age adaptations:
• K–1: Focus on “We can always talk to Him.”
• 2–3: Ask, “What’s one area you want God to help you grow? How can you remember to keep talking to Him about it?”
• 4–5: Get more honest:
“Where do you feel like God has let you down or not answered your prayers? Is there a trusted adult you can talk with about it? Let’s look up some passages that remind us that God is loving and wise and faithful and always looking out for our good.”
Theology guardrail:
Avoid saying: “If you just pray hard enough, God will always say yes.”
Instead: “God always hears you. He always loves you. Sometimes, He says ‘yes,’ sometimes ‘no,’ sometimes ‘wait.’ But He never quits on you.”
5. Spiritual Gifts (Different Pieces, Same Set)
Big Idea:
God gives different gifts so we can serve together. [Reinforcement lesson for lesson #2 above. Use it to review that lesson and help this concept sink into your kid’s worldview.]
Passage:
Romans 12:4–8
What you need:
• LEGO bricks
• Enough unique pieces so each child can have something different (window, wheel, strange color, etc.), in addition to their collection of basic bricks
Activity:
1. Hand each child one unique piece and a handful of basic bricks.
2. Challenge: “Create anything you want, but you must include your special piece.”
3. After they build, bring all their creations together on one big baseplate.
Ask:
• “What would happen if we left some builds out?”
• “How did your special piece change your creation?”
• “How is this like the way God made you?”
Explain:
“God doesn’t give everyone the same gifts. Some of you love to help. Some are great encouragers. Some love to pray. Some like to lead. In church, we’re like a big LEGO set. God designed each person to be needed.”
Long-term discipleship angle:
Combined with the “Body of Christ” lesson, this helps kids see:
• “I have a place.”
• “My gifts are for serving others, not just making myself look good.”
Age adaptations:
• K–1: Emphasize, “God made you special and important.”
• 2–3: Have them share one way they like to help at church or home.
• 4–5: Let them name possible spiritual gifts they see in each other:
“I see you encouraging others. I see you serving quietly…”
Theology guardrail:
Be careful not to reduce spiritual gifts to “talents” only.
Gently note: “God can use your talents, but He also gives you special ways to bless others through His Holy Spirit. However He’s wired you, you matter in His family.”
How to Use LEGO Object Lessons in Sunday School, Kids Church, or Family Devos
Now that we’ve walked through some specific LEGO Bible object lessons, let’s zoom out and talk strategy.
How do you use these in a way that serves long-term discipleship?
1. Start with the doctrine, not the bricks
The temptation is:
“I’ve got a bucket of LEGO bricks. What cool thing could I do this week?”
Better questions would be:
1. What Biblical truth am I trying to teach?
o Jesus as our foundation
o Salvation by grace
o Slow growth in holiness
o Church and spiritual gifts
o God’s presence in suffering
2. What misunderstanding do my kids have about this?
o “If I’m a Christian, nothing bad should happen to me.”
o “God only loves me when I do enough good things.”
o “I’m not important if I’m not on stage.”
3. Which LEGO picture fits that logic?
o Foundation vs. wobble
o Messy build vs. new plan
o Lone brick vs. many pieces
o Break and rebuild
o Slow “upgrade” over time
When you start with Scripture and doctrine, the object lesson becomes a servant, not the star.
2. Adapt by age band
Here’s a quick way to think about adapting your LEGO Bible object lessons:
• K–1
o Big pieces, big motions, short time.
o One main sentence you repeat:
“Jesus is our rock.” “God is still building us.”
o Lots of call-and-response.
• 2–3
o Simple challenges.
o More “why” questions.
o Help them connect the picture to real feelings:
“When you feel left out, remember you’re still part of God’s build.”
• 4–5 (including the “too cool” crew)
o Timed builds, competitions, challenges with “plot twists.”
o Deeper questions:
“Where do you feel wobbly right now?”
“What’s one ‘brick’ you think God might be asking you to add this week?”
With all ages, don’t be afraid to use words like justification and sanctification. Just be sure to explain them. Kids ability to understand theology terms will surprise you.
3. Fit them into your structure
• Sunday School / small groups
o Great for hands-on building for everyone.
o Plenty of time for discussion questions.
• Kids Church / large group
o Use a couple of kids up front to build as a demonstration while everyone watches.
o Then send groups to discuss and maybe do a mini-build.
• Family devos
o One short build, one short reading, one simple question:
“What does this show us about God?”
LEGO Bible object lessons can even fit into kids’ sermons or short children’s sermons in the main service. Just keep it simple, visual, and tightly connected to the Biblical text.
Above all, remember:
The goal isn’t just to have memorable sermons for kids.
The goal is to help children know, love, and follow Jesus with a faith that can withstand real life.
LEGO bricks are just one of the items God can use. But they’re a pretty great one.
Conclusion:
Take advantage of kids’ natural love for LEGO bricks. Incorporate them into your lessons often.
Then, every brick on the floor becomes a reminder:
God is building something.
In your kids.
In your ministry.
In you.
Piece by piece.

Good news: It Only Takes 1.71 Days to Poop Out a Lego
We won't go into a lot of graphic detail (you're welcome), but we should point out that the researchers used a Found And Retrieved Time metric in the study. Think about the acronym for "Found And Retrieved Time," and you'll realize these researchers had a sense of humor!

Bad news: Walking on Legos Hurts More Than Walking on Hot Coals or Broken Glass
Lego-walks are becoming a popular party game. And big stars like "Dude Perfect" are competing for the world record in Lego-walking.
But Scott Bell, two-time holder of the Guinness Book of World Records for the longest-ever barefoot walk over hot coals, says he would rather walk over coals or broken glass than Legos.
Of course, coal-walkers and glass-walkers use science to avoid pain – certain coals have a low heat transfer coefficient, so it's not that painful if you keep moving. And if you break glass into small enough pieces and spread your weight evenly over enough pieces, no edge cuts into your foot that badly.
But there's no secret to lessen the pain when walking barefoot on Legos. Just remind yourself that it's part of serving the Lord in children's ministry.
And maybe 2 Cor 4:17 applies: "For our light and momentary troubles are achieving for us an eternal glory that far outweighs them all."
