Matthew Chapter 3 introduces John the Baptist.

Matthew 1 showed the genealogy and birth of Christ.

Matthew 2 showed the Magi, Herod’s opposition, the flight to Egypt, and Jesus settling in Nazareth.

Matthew 3 now moves forward to John preaching in the wilderness of Judea.

John’s message is direct:

“Repent, for the kingdom of heaven is at hand.”

This chapter is about repentance, confession, judgment, baptism, and the public revealing of Jesus as the beloved Son of God.

Repent, for the Kingdom of Heaven Is at Hand

John begins by saying:

“Repent, for the kingdom of heaven is at hand.”

This does not mean, “Be good so God will have more power to fight evil.”

God does not need human repentance in order to become stronger. God is already sovereign. He does not gain power from our obedience.

The point is different.

The kingdom of heaven is at hand because God’s promised saving reign is drawing near in Christ. The King is coming. Therefore, people must repent.

Repentance is always the right response to sin. But John’s message adds urgency: the kingdom of heaven is at hand. The King is near, so people must not remain comfortable in sin, religious pride, or outward appearance.

Repentance means turning from sin toward God. It is not merely feeling bad. It is a change of mind, heart, and direction. It is recognizing sin for what it is and turning to the Lord for mercy.

John is not saying people can create the kingdom by being better.

He is saying the kingdom is near, so people must prepare rightly.

The King is coming.

So repent.

From a Christian Reformed lens, repentance is not a way to make God gracious. It is itself part of God’s gracious work in sinners. God commands repentance, and by His Spirit He grants true repentance.

The Voice in the Wilderness

Matthew says John is the one spoken of by the prophet Isaiah:

“The voice of one crying in the wilderness: ‘Prepare the way of the Lord; make his paths straight.’”

John is not the Christ. He is the voice preparing the way for Christ.

That matters.

John’s ministry is important, but it is not centered on John. He is preparing the way for another. He is calling people to repentance because the Lord is coming.

The wilderness setting also matters. Matthew does not explain every layer of symbolism, but the wilderness often reminds us of Israel’s history: testing, dependence, wandering, and God’s dealings with His people.

Now, in the wilderness, John announces that something decisive is near.

The Lord is coming.

Prepare the way.

John’s Appearance and Message

Matthew describes John’s clothing and food: camel’s hair, a leather belt, locusts, and wild honey.

This connects John with the Old Testament prophetic pattern, especially Elijah. John is not presented as polished, comfortable, or respectable in a worldly sense. He is a prophet in the wilderness with a direct message from God.

People from Jerusalem, all Judea, and the region around the Jordan come out to him.

They are baptized by him in the Jordan River, confessing their sins.

Matthew does not give us the exact form of their confession.

Maybe some confessed specific sins out loud.

Maybe some acknowledged their sinfulness before God more generally.

Maybe the confession involved public admission that they needed cleansing and mercy.

The text does not spell out the exact words they used.

But the meaning is clear: John’s baptism is connected to repentance and confession of sin.

They are not coming to celebrate how righteous they are.

They are coming as sinners.

Baptism and Confession

John’s baptism is not presented as an empty ritual. It is tied to repentance.

Later in the chapter, John says:

“I baptize you with water for repentance.”

That does not mean baptism is an exchange where John gives baptism and the people purchase it by repenting. It also does not mean John has the power to bring God down to them by the act itself.

The baptism is a sign connected with repentance.

The people are confessing sin.

They are being baptized in water.

They are preparing for the coming One.

John’s baptism points forward. It is not the final cleansing. It is not greater than Christ. John himself makes that clear.

He baptizes with water.

But One mightier than John is coming.

The Pharisees and Sadducees

Then Matthew says many of the Pharisees and Sadducees come to John’s baptism.

John says to them:

“You brood of vipers! Who warned you to flee from the wrath to come?”

That is a strong rebuke.

John is not impressed by their religious status. He does not assume they are safe because they are leaders or because they belong to Abraham’s physical descendants.

He tells them:

“Bear fruit in keeping with repentance.”

That is the key.

True repentance bears fruit. It shows itself. Not perfectly, and not as the ground of salvation, but as evidence of real turning.

John is warning them not to rely on religious identity while refusing repentance.

They should not say, “We have Abraham as our father,” as though that alone protects them from judgment.

God can raise up children for Abraham from stones.

That means physical descent from Abraham is not a shield against God’s judgment if there is no repentance and faith. God is able to fulfill His covenant promises without depending on human pride.

From a Reformed perspective, this is important. Covenant privilege is real, but outward privilege without inward grace does not save. Religious heritage is a blessing, but it is not a substitute for repentance and faith.

Who Warned You to Flee?

John asks:

“Who warned you to flee from the wrath to come?”

The ultimate answer to wrath is Christ. Jesus is the Savior who delivers His people from judgment.

But in Matthew 3, John is not yet fully explaining the cross. He is confronting the Pharisees and Sadducees. He is warning them that judgment is coming and that they must not treat repentance as a show.

So we should be careful.

It is true that Jesus is the One who saves from the coming wrath.

But John’s question here is not exactly a parable where the answer is simply, “Jesus.” It is a prophetic rebuke. John is saying, in effect:

Do not come outwardly while remaining inwardly unchanged.

If you are fleeing wrath, then bear fruit in keeping with repentance.

The Axe at the Root of the Trees

John then says:

“Even now the axe is laid to the root of the trees.”

This means judgment is near.

The picture is of a tree about to be cut down. The axe is not far away in storage. It is already laid at the root.

John continues:

“Every tree therefore that does not bear good fruit is cut down and thrown into the fire.”

The image is serious but not complicated.

A fruitless tree is judged.

John is saying that people who do not bear the fruit of repentance face coming judgment.

This does not mean good works earn salvation. Scripture does not teach that sinners save themselves by producing enough fruit.

But true repentance is not barren. True faith is not fruitless. When God changes a heart, there will be evidence.

Fruit does not purchase salvation.

Fruit reveals the tree.

The One Mightier Than John

John then points away from himself and toward Christ.

He says:

“I baptize you with water for repentance, but he who is coming after me is mightier than I.”

John is not worthy to carry His sandals.

That is humility.

John has a powerful ministry. Crowds are coming to him. People are being baptized. Religious leaders are being confronted.

But John knows his place.

He is not the Savior.

He is not the center.

He is the forerunner.

The One coming after him is mightier.

John baptizes with water.

Jesus will baptize with the Holy Spirit and fire.

The Holy Spirit and Fire

John says Jesus will baptize with the Holy Spirit and fire.

This phrase has been understood in different ways.

It may refer to the saving work of Christ, who pours out the Holy Spirit on His people.

It may also include the idea of judgment, especially because John immediately speaks of the winnowing fork, the wheat, and the chaff.

It may be that the phrase holds together both purification and judgment.

The context clearly includes judgment.

John says the coming One has His winnowing fork in His hand. He will clear His threshing floor. He will gather His wheat into the barn, but the chaff He will burn with unquenchable fire.

That image means Christ separates truly.

Wheat is gathered.

Chaff is burned.

The Messiah brings salvation, but He also brings judgment. He does not merely offer religious inspiration. He comes with divine authority.

This is part of the seriousness of John’s message.

Repent, because the King is near.

Jesus Comes to Be Baptized

Then Jesus comes from Galilee to the Jordan to John, to be baptized by him.

John tries to prevent Him.

He says:

“I need to be baptized by you, and do you come to me?”

John understands that Jesus is greater than he is. John is the sinner. Jesus is the greater One.

So why is Jesus baptized?

Jesus answers:

“Let it be so now, for thus it is fitting for us to fulfill all righteousness.”

This is the key.

Jesus is not baptized because He has sins to confess. He has no sin.

He is baptized to fulfill all righteousness.

This means Jesus is identifying Himself with the people He came to save. He stands with sinners, though He Himself is not sinful. He steps into the waters of repentance, not because He needs repentance, but because He is taking His place with the people He will redeem.

Your instinct is right: Jesus’ baptism signals His identification with sinners.

But it is more than a signal. It is part of His obedient mission. He publicly steps into the path that will lead to the cross.

He will fulfill righteousness for His people.

He will obey where sinners have disobeyed.

He will save those who cannot save themselves.

The Heavens Open

When Jesus is baptized, immediately He comes up from the water.

Then the heavens are opened.

The Spirit of God descends like a dove and comes to rest on Him.

And a voice from heaven says:

“This is my beloved Son, with whom I am well pleased.”

This is one of the clearest Trinitarian moments in the Gospel.

The Son is baptized.

The Spirit descends.

The Father speaks.

The Father declares Jesus to be His beloved Son.

This is not the moment Jesus becomes the Son of God. He already is the Son. Matthew has already told us of His divine conception. But here His Sonship is publicly declared as His ministry begins.

The Father is pleased with Him.

That matters.

John called sinners to repent.

The crowds confessed their sins.

The Pharisees and Sadducees were warned about judgment.

Then Jesus comes into the water, without sin, and the Father declares Him beloved and pleasing.

The Savior sinners need has arrived.

The Message of Matthew Chapter 3

Matthew Chapter 3 is about preparation and revelation.

John prepares the way.

He calls people to repent because the kingdom of heaven is at hand.

He baptizes those confessing their sins.

He warns the Pharisees and Sadducees not to rely on outward religious identity.

He says the axe is already laid at the root of the trees.

He points to the One mightier than himself.

Then Jesus comes.

And when Jesus is baptized, heaven opens.

The chapter begins with John’s voice in the wilderness.

It ends with the Father’s voice from heaven.

John says the King is coming.

The Father says:

“This is my beloved Son.”

From a Christian Reformed lens, Matthew 3 shows repentance, grace, covenant warning, judgment, Christ’s obedience, and the Triune God revealing the Savior.

Repentance does not make God powerful.

God is already powerful.

Repentance is always the right response to sin. But John’s message adds urgency: the kingdom of heaven is at hand. The King is near, so people must not remain comfortable in sin, religious pride, or outward appearance.

Baptism does not save by itself.

It points to cleansing, repentance, and the greater work of Christ.

Religious heritage does not save.

God can raise up children for Abraham from stones.

Fruit does not earn salvation.

But true repentance bears fruit.

And Jesus does not enter the water because He needs cleansing.

He enters because He came to fulfill all righteousness. He stands with sinners, though He is not sinful. He takes His place with the people He came to save, and He begins the obedient path that will lead to the cross.

The kingdom of heaven is at hand.

The axe is at the root.

The winnowing fork is in His hand.

And the beloved Son has come.
