This lesson teaches children that God writes His love and truth on our hearts, so we can carry good news to others. It is made for children ages 5 to 11 and takes about 20 to 30 minutes, including the story, a memory verse, and one activity.
Big Idea
God gives us His Spirit, and His Spirit helps us know Jesus and show His love to everyone we meet. We don’t have to be perfect to share God’s good news, because God is the one who makes us able.
Memory Verse
2 Corinthians 3:3
Being revealed that you are a letter of Christ, served by us, written not with ink, but with the Spirit of the living God; not in tablets of stone, but in tablets that are hearts of flesh.

Teach the children to cup both hands over their heart as they say the words, then open their hands outward like a letter being sent. Repeat it together three times, getting a little softer each time, so the words stay in their hearts.
The Story: 2 Corinthians 3 for Kids
Paul was a teacher who loved the people in the city of Corinth. Some people in Corinth wondered if Paul was really sent by God. They asked him, “Do you have a letter to prove you are good?” Paul smiled and said, “You are my letter!”
Paul meant that the changed lives of the people in Corinth were proof of God’s work. Their hearts had been touched by Jesus. Paul said this good news was not written with ink on paper. It was written by God’s Spirit on people’s hearts.
Long ago, God gave the people of Israel the law on stone tablets through Moses. Moses came down from the mountain, and his face was shining so brightly that the people could not look at him. Paul said that was an amazing gift, but the Spirit of God brings even greater light.
Paul told the Corinthians that when people turn to the Lord, the covering on their eyes is taken away. They can see clearly. Paul said the Lord is the Spirit, and where the Spirit of the Lord is, there is freedom. Paul said that as we look at the Lord, we become more like Him, shining brighter and brighter.
Read It Together
2 Corinthians 3:2
You are our letter, written in our hearts, known and read by all men…
(WEB)
Point out that Paul called the believers a letter that everyone could read. Ask the children what people could learn about Jesus by looking at how we treat others.
2 Corinthians 3:17
Now the Lord is the Spirit and where the Spirit of the Lord is, there is liberty.
(WEB)
Show the children that the Lord’s Spirit brings freedom, not fear. Point out that the word “liberty” means being free to live the way God made us to live.
2 Corinthians 3:18
But we all, with unveiled face seeing the glory of the Lord as in a mirror, are transformed into the same image from glory to glory, even as from the Lord, the Spirit.
(WEB)
Explain that as we look at Jesus through prayer and reading the Bible, we slowly become more like Him. Emphasize that this change happens gradually, one day at a time.
Talk About It
- What is one thing a letter can do that a person can also do for others?
- How did Paul’s friends in Corinth show that God was working in their lives?
- Why do you think God wants His love written on our hearts instead of only on stone?
- What is one way you can let people see Jesus in how you act at school or at home?
- When you feel like you can’t do something kind, what can you remember about where your strength comes from?
Activity Ideas
Heart Letter Drawing
You will need paper, crayons or markers, and scissors. Have each child trace a heart shape on paper, then write or draw one way Jesus helps them show kindness. Let them decorate the heart with bright colors, and then display the hearts on a wall to show that God’s love is written on many hearts.
Letter Relay
You will need two bowls, a handful of small paper hearts, and a spoon. Divide the children into two teams and have them carry one heart at a time on a spoon from one bowl to the other without using their hands. Each time they finish, have them say a word that describes how the Spirit helps us, like “gentle,” “kind,” or “brave.” Cheer for every team.
Take-Home Mirror Reminder
You will need a small mirror, a sticky note, and a marker. Ask each child to write “I am God’s letter” on the sticky note and place it on the edge of their bathroom or bedroom mirror. When they see their reflection each morning, they can remember that God is changing them to look more like Jesus every day.
Teacher Notes
For adults, this passage teaches that the believer’s life is the living evidence of God’s work, written by the Spirit rather than carved in stone. Paul’s point is not self-promotion but humble dependence, since he says our sufficiency comes from God. The contrast between the old covenant written on stone and the new covenant written on hearts shows God’s desire for a relationship that changes us from within.
When teaching children, avoid overstating how quickly or perfectly we will change. Paul describes a gradual transformation from one degree of glory to another, not an instant result. Help children understand that growing like Jesus takes time and that God is patient with them as they learn.
A Prayer to Close
Dear Jesus, thank you for writing your love on our hearts by your Spirit. Help us to be letters that show your kindness to everyone we meet. Thank you that we can grow to be more like you each day. We pray this in your name. Amen.
