Mark begins his Gospel quickly and directly.

There is no long genealogy like Matthew.
No birth narrative like Luke.
No opening meditation on the eternal Word like John.

Mark begins with action:

“The beginning of the gospel of Jesus Christ, the Son of God.”

Many scholars believe Mark was the first Gospel written, and Mark’s style feels urgent from the start. He moves quickly. He uses words like “immediately.” He shows Jesus acting, preaching, healing, casting out demons, and calling people to follow Him.

From a Christian Reformed lens, Mark 1 shows us that the gospel begins with God’s action in Christ. Jesus is the Son of God, the promised King, the obedient representative of His people, and the Savior with authority over sin, Satan, sickness, and uncleanness.

The Beginning of the Gospel

Mark opens with:

“The beginning of the gospel of Jesus Christ, the Son of God.”

The word gospel means good news. But this good news does not begin with human effort, moral improvement, or religious achievement. It begins with God’s action in Christ.

Jesus is not introduced as one religious teacher among many. He is the Christ, meaning the Messiah, the anointed King promised in the Old Testament. He is also the Son of God.

In a Christian Reformed understanding, the gospel is not advice about how people can climb up to God. It is the announcement that God has come down in Christ to save sinners.

John the Baptist Prepares the Way

Before Jesus appears publicly, John the Baptist comes preaching in the wilderness.

Mark connects John’s ministry to Old Testament prophecy:

“Behold, I send my messenger before your face, who will prepare your way.”

John is the forerunner. He is not the Savior. He is the messenger preparing the way for the Lord.

John preaches a baptism of repentance for the forgiveness of sins. He calls people to turn from sin and prepare for the coming One.

But John also knows his place. He says:

“After me comes he who is mightier than I.”

John is great, but Christ is greater.

John baptizes with water.
Jesus baptizes with the Holy Spirit.

This reminds us that outward signs alone cannot save. Water baptism points to cleansing, but only Christ gives the inward cleansing of the Spirit. From a Reformed perspective, this distinction matters. The sign is important, but the saving power belongs to Christ.

Jesus Is Baptized

Then Jesus comes to be baptized by John.

This may seem surprising. Jesus has no sin to confess. He does not need repentance. Yet He identifies Himself with His people.

At His baptism, the heavens are torn open, the Spirit descends on Him like a dove, and the Father says:

“You are my beloved Son; with you I am well pleased.”

Here we see the Trinity revealed:

The Son is baptized.
The Spirit descends.
The Father speaks.

Jesus begins His public ministry under the pleasure and approval of the Father. He is the beloved Son. He is the faithful servant. He is the true Israel who will obey where Israel failed.

Jesus Is Tempted in the Wilderness

Immediately after His baptism, the Spirit drives Jesus into the wilderness.

There He is tempted by Satan for forty days.

This connects Jesus to Israel’s story. Israel was tested in the wilderness and repeatedly failed. Jesus enters the wilderness and remains faithful.

From a Reformed lens, Jesus is the representative head of His people. He does not merely show us how to resist temptation. He obeys in our place.

Where Adam failed, Christ obeys.
Where Israel failed, Christ obeys.
Where we fail, Christ obeys.

This is part of the good news. Our salvation rests not on our perfect obedience, but on Christ’s perfect obedience for us.

The Kingdom of God Is at Hand

After John is arrested, Jesus begins preaching:

“The time is fulfilled, and the kingdom of God is at hand; repent and believe in the gospel.”

This is a major moment.

The time is fulfilled.
The promises are coming to their goal.
The King has arrived.
The kingdom is near because the King is near.

Jesus calls people to repent and believe.

Repentance means turning from sin.
Faith means trusting in Christ.

From a Christian Reformed perspective, both repentance and faith are gifts of grace. We truly repent. We truly believe. But we do so because God first works in us by His Spirit.

The gospel command is real: repent and believe.
The grace behind it is also real: God gives life to dead sinners.

Jesus Calls His First Disciples

Jesus calls Simon, Andrew, James, and John.

They are fishermen. They are working ordinary jobs. Jesus comes to them and says:

“Follow me, and I will make you become fishers of men.”

They leave their nets and follow Him.

This shows Christ’s authority in calling disciples. He does not merely offer religious advice. He summons people into a new life under His lordship.

From a Reformed lens, this reminds us that the call of Christ is powerful. The same Lord who commands demons and heals the sick also calls sinners to Himself.

Discipleship begins with Christ’s initiative.

Jesus calls.
They follow.

Jesus Teaches With Authority

In Capernaum, Jesus enters the synagogue and teaches.

The people are astonished because He teaches “as one who had authority, and not as the scribes.”

Jesus does not merely repeat opinions. He speaks with divine authority.

This is one of the major themes of Mark 1. Jesus has authority:

Over doctrine.
Over demons.
Over sickness.
Over uncleanness.
Over disciples.
Over the direction of His mission.

His Word is powerful because He is the Son of God.

In a Christian Reformed view, the Word of Christ does not simply inform. It creates, commands, judges, heals, and saves. When Christ speaks, reality obeys.

The Demons Recognize Jesus

In the synagogue, a man with an unclean spirit cries out:

“I know who you are—the Holy One of God.”

The demon has correct theology in one sense. He knows Jesus’ identity. He knows Jesus is holy. He knows Jesus has authority.

But this is not saving faith.

James 2:19 says even the demons believe—and shudder.

The demons know true things about Jesus, but they do not love Him, trust Him, repent, or worship Him. Their knowledge is filled with terror, not faith.

This is an important warning. A person can know facts about Jesus and still not belong to Him.

Saving faith includes knowledge, but it is more than knowledge. It includes trust in Christ, love for Christ, and receiving Him as Savior and Lord by the work of the Holy Spirit.

Why Jesus Silences the Demons

Jesus rebukes the demon and says:

“Be silent, and come out of him!”

Jesus does not allow the demon to keep speaking, even though the demon’s words are technically true.

Why?

First, Jesus will not receive testimony from unclean spirits. The kingdom of God is not advanced by demonic witnesses.

Second, Jesus controls the timing and meaning of His revelation. In Mark, people often misunderstand what kind of Messiah Jesus is. Many expect political power or miracle-working fame. But Jesus’ identity must be understood through the cross.

Third, Jesus is sovereign. Even the demons must obey His Word.

From a Reformed perspective, this shows Christ’s absolute authority over the spiritual realm. Satan and demons are real, but they are not equal opposites to God. They are creatures. Christ is Lord.

The demon comes out because Jesus commands it.

Jesus Heals Simon’s Mother-in-Law and Many Others

After leaving the synagogue, Jesus enters the house of Simon and Andrew. Simon’s mother-in-law is sick with a fever.

Jesus takes her by the hand and lifts her up, and the fever leaves her.

Then many people come to Him with sicknesses and demons, and Jesus heals many.

Mark is showing the compassion and authority of Christ. Jesus does not only preach. He also restores.

His miracles are signs of the kingdom. They show that in Christ, God’s saving reign has arrived.

Sickness, demons, and uncleanness are not ultimate. Christ has authority over them.

But Jesus’ miracles are not merely displays of power. They reveal His mercy.

He comes near to the suffering.
He touches the weak.
He lifts up the sick.
He delivers the oppressed.

Jesus Prays in a Desolate Place

After a long day of ministry, Jesus rises very early in the morning and goes to a desolate place to pray.

This is a beautiful and important moment.

Jesus is the Son of God, yet in His true humanity He prays. He depends on the Father. He communes with the Father. He does not allow the demands of the crowds to control His mission.

When the disciples find Him, they say:

“Everyone is looking for you.”

But Jesus responds:

“Let us go on to the next towns, that I may preach there also, for that is why I came out.”

This shows that Jesus’ mission is not controlled by popularity.

The crowds want miracles. Jesus came to preach the gospel of the kingdom.

The miracles matter, but they are not the center. The Word is central. Christ came to proclaim the kingdom, call sinners to repentance, and move toward the cross.

Jesus Cleanses the Leper

At the end of the chapter, a leper comes to Jesus and says:

“If you will, you can make me clean.”

This man is not only sick. He is ceremonially unclean. Under the Old Testament law, a person with serious skin disease was separated from normal worship and community life.

So he does not merely ask to be healed. He asks to be made clean.

Jesus is moved with pity. He stretches out His hand, touches him, and says:

“I will; be clean.”

Normally, touching the unclean made a person ceremonially unclean. But with Jesus, the movement is reversed.

The man’s uncleanness does not contaminate Jesus.
Jesus’ cleanness overcomes the man’s uncleanness.

This is a powerful picture of the gospel.

Sinners do not cleanse themselves and then come to Christ. Christ comes near and cleanses sinners by His grace.

Show Yourself to the Priest

After cleansing the man, Jesus tells him not to tell everyone, but to go show himself to the priest and offer what Moses commanded.

This refers to Leviticus 13–14.

The priest had the official role of examining someone with a skin disease and declaring whether that person was clean. If the person was cleansed, offerings were made and the person could be restored to public worship and community life.

Jesus tells the man to follow that process.

This shows that Jesus is not against Moses. He honors the law. But He also shows that He is greater than the ceremonies of the law.

The law could identify uncleanness.
The priest could declare cleansing.
But only God could actually make the man clean.

Jesus does what only God can do.

The Man’s Disobedience and Jesus Outside

Jesus clearly tells the man not to spread the news widely.

But the man disobeys. He talks freely and spreads the report everywhere.

His excitement is understandable, but it is still disobedience. Good intentions do not make disobedience harmless.

Because of this, Jesus can no longer openly enter a town. He stays out in desolate places, and people come to Him from every direction.

There is a striking gospel picture here.

The leper had been the outsider.
Jesus cleanses him and restores him.
Then Jesus ends up outside in desolate places.

The outsider is brought in.
Jesus goes out.

This points forward to the cross. Christ takes the place of the unclean. He bears shame, rejection, and judgment so that sinners may be brought near to God.

Jesus does not approve of the man’s disobedience. But He willingly bears the cost of mercy.

The Comfort of Mark 1

Mark 1 gives deep comfort because it shows us who Jesus is.

He is the Christ.
He is the Son of God.
He is the beloved Son of the Father.
He is the faithful representative of His people.
He is the preacher of the kingdom.
He is the caller of disciples.
He is the teacher with authority.
He is Lord over demons.
He is healer of the sick.
He is the cleanser of the unclean.
He is the Savior who goes outside so sinners may be brought in.

From a Christian Reformed lens, this chapter reminds us that salvation begins with God’s grace, not human strength.

The demon-possessed man cannot free himself.
The sick cannot heal themselves.
The leper cannot cleanse himself.
Sinners cannot save themselves.

But Christ speaks, touches, heals, cleanses, commands, and saves.

The gospel begins not with what we do for God, but with what God has done for us in Jesus Christ.

Mark begins with urgency because the King has arrived.

The kingdom of God is at hand.

Repent and believe in the gospel.
