A Sunday School Lesson: Luke 13:18-30: Growing for God’s Kingdom

Growing for God’s Kingdom

This Sunday School lesson is intended for upper elementary students. All lessons on this website are protected by copyright, but you can use them for free in small groups or Sunday School classes. You may share a link to this page, but please do not copy these pages and put them on other websites.

The Big Idea

Jesus uses everyday examples to show that the Kingdom of God starts small and grows to include people from every corner of the world, but he also warns that we must truly know him to enter it.

Lesson Objectives

  1. Students will learn that the Kingdom of God is a growing work that starts in small, quiet ways.
  2. Students will understand that the door to salvation is narrow and requires a heart that truly belongs to Christ.
  3. Students will recognize that God welcomes people from all nations and directions into his heavenly feast.

Class Setting Notes

  1. Recommended for upper elementary Sunday School.
  2. Lesson length: 45 to 60 minutes. Can be shortened or extended based on activities selected.

Opening Activity: The Mystery of the Growing Dough

  1. Bring in a small amount of bread dough that has not risen and a larger bowl of dough that has already been rising with yeast for an hour.
  2. Ask the students to describe the difference between the two bowls.
  3. Show them a tiny mustard seed or a very small pinch of yeast.
  4. Explain that today we are going to learn how Jesus describes the way God changes the world using things that seem very small at first.
  5. At the end of class, show them the progress of both bowls.

This activity helps introduce the concept of internal growth and how God works in ways that are not always visible right away.

Bible Reading

Ask the class to read Luke 13:18-30 aloud together or have one person read it.

Additional Reading: Choosing the Right Bible Translation

Suggested prompts:

As the class reads aloud, consider asking some of these prompts:

  1. Notice how the mustard seed does not stay small but becomes a place where birds can live.
  2. Think about how a tiny bit of yeast can change a whole bushel of flour.
  3. Watch what happens when people knock on the door after the master has already closed it.
  4. Listen for the names of the famous men from the Old Testament who will be at the feast.
  5. Pay attention to the four directions Jesus mentions to show how big the Kingdom will be.

Teacher Background Notes

  1. Mustard seeds were known in the ancient world for being incredibly small, but the plants could grow to be ten or fifteen feet tall.
  2. Yeast, or leaven, was often used by Jesus as a picture of how a quiet influence can spread through an entire group of people or a single heart.
  3. When Jesus mentions traveling toward Jerusalem, he is reminding his followers of his coming sacrifice on the cross.
  4. The narrow door refers to the fact that there is only one way to be saved, which is through faith in Jesus Christ alone.
  5. The mention of Abraham, Isaac, and Jacob reminds the listeners of the promises God made to the fathers of the faith in the book of Genesis.

Theological Insights

  1. The Kingdom of God is both a present reality in the hearts of believers and a future home in Heaven.
  2. Grace is a gift from God, but Jesus calls us to strive to enter the door, meaning we must be serious about our faith.
  3. Many people might know about Jesus without actually knowing him as their Lord and Savior.
  4. God has a plan to save people from every tribe, tongue, and nation, showing his great mercy.
  5. In the Kingdom of God, the world’s ideas about who is important are turned upside down.

Discussion Questions

Understanding the Text

  1. What happens to the mustard seed after it is planted in the field?
  2. What does the yeast do to the flour when the woman mixes it in?
  3. Why does the master of the house refuse to open the door for the people standing outside?
  4. What four directions do the people come from to sit at the feast in the Kingdom of God?

Personal Reflection and Application

  1. How have you seen God’s love grow in your own heart or in your family?
  2. What are some small ways you can serve God this week that might grow into something bigger?
  3. What does it look like to be a person who truly knows Jesus instead of just knowing facts about him?
  4. How does it make you feel to know that God wants people from all over the world to be in his family?

Suggested Activities

Mustard Seed Art

  1. Give each student a piece of paper and one tiny seed or a small dot made with a marker.
  2. Have them draw a large, beautiful tree growing out of that tiny dot.
  3. Ask them to write the name of someone they are praying for on one of the branches.

This activity helps students visualize how God can take a small prayer or a small person and do great things through them.

The Narrow Door Challenge

  1. Create a narrow path or a small doorway using chairs or tape on the floor.
  2. Have the students try to walk through it while carrying many large items that represent distractions or selfishness.
  3. Talk about how we must leave our own pride behind to follow Jesus through the narrow door.

This activity helps introduce the idea that following Jesus requires us to put him first above our own wants.

Feast from the Four Corners

  1. Set up a table and have the students sit down as if they are at a grand dinner.
  2. Place cards on the table that say East, West, North, and South.
  3. Discuss different countries and people who might be sitting at that table in Heaven one day.

This activity illustrates the beauty of a diverse church and the promise of a future celebration with God.
