Causing Children to Sin – They Are Watching

What if our everyday actions are teaching children more than our words ever could? In Matthew 18, Jesus delivers one of His strongest warnings—one that should cause every Christian to pause and reflect. This Bible study explains how our behavior, attitudes, and choices can either guide children toward Christ or cause them to stumble.

Following the teachings of Christ is always the right path, especially when it comes to our own sin and the influence we have on others. That influence matters deeply when children and new believers are watching.

In this lesson, we take a look at Jesus’ words in Matthew and ask some honest questions:

• How do our actions affect children and new Christ followers?
• What example are we really setting?
• Are we helping others grow—or unintentionally causing them to sin?

An example: If you recently accepted Jesus as Savior, your life may be one of the first pictures people see of what following Christ looks like.

Jesus Warns Against Causing Children to Sin

Christians Setting Examples That Matter

“Whoever then humbles himself as this child, he is the greatest in the kingdom of heaven.” (Matthew 18:4)

“And whoever receives one such child in My name receives Me; but whoever causes one of these little ones who believe in Me to stumble, it would be better for him to have a heavy millstone hung around his neck, and to be drowned in the depth of the sea.” (Matthew 18:5–6)

These are strong words—and they’re meant to be. Jesus makes it clear that how we treat children, and how we live in front of them, is not a small issue.

Is Matthew 18:6 Really Talking about Children?

Short answer, yes—but not only children in age.

In Matthew 18, Jesus is speaking about literal children and those who are young in faith. This includes new believers who are still learning what it means to follow Christ. When Christians fail to live out their faith authentically, it can confuse, discourage, or even push others away.

This is why the topic of causing children to sin applies directly to how Christians set examples today.

Our Actions: Who Is Watching?

It’s easy to forget how closely children observe us. They listen to our words—but they study our actions.

For example, we may sit in church on Sunday, nodding along to the message. Yet moments later, we gossip in the parking lot or speak harshly to others. Children notice the disconnect, and they learn from it.

This reminds me of a saying I once heard from Zig Ziglar. He said;

“What you do speaks so loudly, I can’t hear a word you’re saying.“

Let’s Be Honest—I’m Guilty Too

This truth can feel uncomfortable. As I write this, I know I’m not immune. While I may not cause a scene, I don’t always respond with the patience or grace that reflects Christ. That realization should humble all of us.

They Are Paying Attention

Children are far more perceptive than we often assume. When they see us stumble—what Jesus calls “causing a stumble”—they may begin to believe that behavior is acceptable. Without realizing it, we may have just taught them how to sin.

Should We Cut Off Our Hands?

Later in Matthew 18, Jesus uses dramatic language, saying it is better to enter life maimed than to be cast into hell with all our limbs intact.

“If your hand or your foot causes you to stumble, cut it off and throw it from you.” (Matthew 18:8)

Jesus is not calling for physical harm. He is calling for serious action against sin. This means pausing, praying, and removing influences that lead us—or others—away from God.

That’s why learning to pray before we act matters so much.

Other Ways We Cause Children to Stumble

Belittlement and Being Dismissive

Another overlooked way we cause children to sin is through belittlement or neglect. When a child asks a question or seeks attention and is brushed aside, they learn that they are unimportant.

We would never do this to a friend. Children deserve the same respect.

Every Person Is Important to God

Jesus repeatedly shows how deeply He values every individual. He teaches that when even one strays, it matters.

As Christians, it is our responsibility to reflect that same concern and compassion, especially toward children.

Jesus Loves the Little Children

During His short earthly ministry, Jesus was incredibly busy. Yet He always made time for children. That raises an important question: are we busier than Jesus?

Even five or ten intentional minutes can make a lasting difference in a child’s life—and sometimes in our own.

Love in Christ,
