Matthew 5:13-16

Think for a moment about the people who live closest to you.

The people across the street. The families on your kids’ sports teams. The students you sit beside at school. The coworkers you see every day.

Over time, they probably know more about you than you realize. They hear how you talk. They learn what you value. They see how you respond when life gets difficult. They get glimpses of the kind of person you really are.

Which raises an important question:

When the people around you see your life, how well can they see Jesus?

Can they see something different about you because you follow Him?

In Matthew 5:13–16, Jesus gives His disciples two simple pictures for what their lives should look like in the world: salt and light. Together, these pictures show us that Jesus calls His disciples to shine His light in the world for God’s glory.

Live Distinctly

Jesus says to His disciples:

“You are the salt of the earth. But if salt loses its flavor, how can it be made salty again? It is no longer good for anything except to be thrown out and trampled on by people. You are the light of the world. A city located on a hill cannot be hidden. Matthew 5:13–14

To understand these words, it helps to remember where they occur. Jesus is preaching the Sermon on the Mount, teaching His disciples what life looks like in His kingdom.

Immediately before this, Jesus gives the Beatitudes. He describes people who humbly depend on God, hunger for righteousness, show mercy, pursue purity and peace, and remain faithful even when following Jesus costs them.

Then He turns to those same people and says, “You are the salt of the earth. You are the light of the world.”

Even the word you matters. In Greek, it is plural. Jesus isn’t merely forming isolated individual disciples. He is forming a transformed community—a people whose life together looks different because they belong to Him.

So why does Jesus call them salt?

Salt had several uses in the ancient world. It could season, preserve, and purify. Whatever function Jesus has foremost in mind, one thing is clear: salt is useful because its distinctive quality positively affects whatever it touches.

That is precisely what Jesus warns His disciples not to lose.

If Christians think like the world, speak like the world, pursue everything the world pursues, and compromise everywhere the world compromises, what exactly is distinctive about our witness?

Jesus calls His people to be different.

Not weird. Not rude. Not self-righteous. But distinctly shaped by Him.

Then Jesus changes the picture: “You are the light of the world.”

This image has already appeared in Matthew. One chapter earlier, Matthew quotes Isaiah: “The people who live in darkness have seen a great light” (Matthew 4:16). God’s promised light has dawned in the coming of Jesus.

And now Jesus turns to His disciples and calls them the light of the world.

The light that has come through Jesus is now meant to become visible through the lives of His people.

What does that light look like?

Jesus spends much of the rest of the Sermon on the Mount showing us. In a world of anger, His disciples pursue reconciliation. In a world of sexual brokenness, they pursue purity. When others retaliate, they love their enemies. Instead of living for possessions, they store up treasure in heaven. Instead of being consumed by anxiety, they trust their Father.

This is what it means to live distinctly.

Because of Jesus, our lives should increasingly look different. His Spirit changes us. His Word shapes us. His grace makes us new from the inside out. His light becomes increasingly visible through our lives.

John Wesley once saw a powerful example of this kind of distinctiveness.

In 1736, Wesley was crossing the Atlantic when a violent storm struck the ship. The wind and waves battered the vessel, and the English passengers around him panicked. But Wesley noticed a group of Moravian Christians responding differently. In the middle of the storm, they calmly worshiped God and sang hymns.

They faced the same storm as everyone else, but they faced it differently because of their faith.

Their confidence in God exposed something missing in Wesley’s own faith and became part of God’s work in his life.

That’s what it looks like to be salt and light. We face the same broken world everyone else faces, but we live differently because Jesus is changing us.

So ask yourself: If the people around you watched your life closely, where would they see that you are different because you follow Jesus?

Live Visibly

But we need to be careful.

We can hear “live distinctly” and assume the goal is separation from the world.

That isn’t what Jesus says.

What good is salt if it never comes into contact with anything? What good is light if no one can see it?

Jesus doesn’t call His disciples to preserve their distinctiveness by withdrawing from the world. He calls them to bring that distinctiveness into the world.

Jesus continues His light metaphor with two additional pictures: a city and a lamp.

You are the light of the world. A city located on a hill cannot be hidden. People do not light a lamp and put it under a basket but on a lampstand, and it gives light to all in the house. In the same way, let your light shine before people… Matthew 5:14–16a

A city on a hill cannot be hidden. No one lights a lamp and then covers it with a basket. You put it on a lampstand precisely so that it can give light.

The whole picture is about visibility.

Light fulfills its purpose when it can be seen.

Jesus even says that people should “see your good works.” The word translated good carries the idea of something noble, commendable, even beautiful.

But people can only see those good works if we are actually living among them.

Being salt and light requires proximity.

That can be challenging because Christians can gradually build lives in which almost everyone around us is already a Christian. We attend church with Christians. We join Life Groups with Christians. Our closest friends are Christians.

We need Christian community. Jesus is not calling us away from it.

But He is calling us to resist the temptation to withdraw from people who don’t know Him.

And isn’t that exactly what we see in Jesus?

Jesus was perfectly holy, yet He constantly moved toward sinners. Matthew describes Him eating at a table surrounded by tax collectors and sinners while the religious leaders wondered why He would associate with people like them (Matthew 9:10–11).

Jesus had no problem being close to people who were far from God.

Why?

Because Jesus didn’t come to avoid sinners. He came to save them.

He ultimately gave His life on the cross so sinners could be forgiven and reconciled to God. So it shouldn’t surprise us that during His ministry, Jesus gladly ate meals with them, cared for them, and spent time with them.

Jesus shows us that holiness and proximity to the lost are not opposites.

And He calls His disciples to live like Him.

Not to hide our light. Not to avoid the darkness. But to carry His light into it.

Are you living close enough to people who don’t know Jesus for them to actually see the light of Jesus in you?

Live for His Glory

There is one final phrase in Jesus’ teaching that may be the most important of all.

Why should we live differently? Why should we live visibly? What are we ultimately hoping will happen when people see our lives?

Jesus tells us:

In the same way, let your light shine before people, so that they can see your good deeds and give honor to your Father in heaven. Matthew 5:16

The crucial words are “so that.”

This is the purpose. This is where the whole passage is headed.

People see the lives of Jesus’ disciples and give glory to their Father in heaven.

They see your life, but they give glory to your Father.

That’s the target.

The goal isn’t to convince everyone that Christians are impressive people. It isn’t to build our reputation, make our church famous, or receive applause for being generous, moral, or kind.

Our lives are meant to make Him known.

Think about the moon on a clear night. It can brilliantly illuminate the night sky, but the moon has no light of its own. It shines because it reflects the light of the sun.

That is a beautiful picture of the Christian life.

We aren’t the source of the light.

Jesus is.

We are simply reflecting the glory of the One whose light has changed us.

When people see grace in us, we want them to discover the God who has shown us grace.

When they experience love from us, we want them to discover the God who first loved us.

When they see hope in us, we want them to discover the One in whom our hope is found.

We aren’t trying to make ourselves known.

We want to make Him known.

So ask yourself one final question:

When people see the way you live, who are they being pointed toward?

Shine Where You Are

Jesus’ calling in Matthew 5 is remarkably simple, but it reaches into every part of our lives.

Live distinctly. Don’t compromise with the world. Prayerfully let the Spirit shape your heart so that your life increasingly looks like Jesus.

Live visibly. Don’t withdraw from the world. Live in meaningful proximity to people who are far from God. This week, intentionally move toward someone. Walk across the street. Invite them over. Ask a meaningful question. Listen to their story.

Live for His glory. Don’t perform for your own name. Let your words, actions, character, and relationships point beyond you to Jesus.

You don’t have to move across an ocean to obey Matthew 5.

God has already placed you somewhere.

He has placed you in a neighborhood. In a workplace. In a classroom. On a team. In a family. Among particular people whom He loves.

So shine where you are.

You are the salt of the earth.

You are the light of the world.

Let your light shine before others—for His glory.
