Who Is Jesus? What the Gospel of Mark Wants You to Know

One verse. That is all it takes for Mark to tell us everything we need to know. Before any miracle, any sermon, any confrontation with religious leaders, Mark opens his Gospel with a single, sweeping declaration that sets the stage for everything that follows.

Who Wrote the Gospel of Mark and Why Does It Matter?

John Mark, also known simply as Mark, was a Jewish Christian who grew up at the very center of the early church. His mother's home in Jerusalem served as a gathering place for believers, and Mark had a front-row seat to the excitement, the persecution, and the remarkable advancement of the Gospel in those earliest days.

He was also well connected. Barnabas, the great encourager, was his cousin. Paul, the missionary and church planter, invited him on the first missionary journey. And Peter, the apostle, became one of his closest associates, sharing with him firsthand accounts of Jesus's life and ministry.

What Happened When Mark Walked Away from the Mission?

Despite those incredible mentors, Mark stumbled. Partway through that first missionary journey, he left. We do not know exactly why. Perhaps the tension was too great, or the emotions overwhelmed him. Whatever the reason, this promising young man abandoned the mission before it was complete.

It looked like a story of someone who started well but could not finish well.

But that is not where the story ended. Barnabas kept believing in him. Peter kept pouring into him. And eventually, Paul himself said to Timothy, "Bring Mark with you, for he is very useful to me in ministry." The man who once walked away from the Gospel was later entrusted with writing the first of the four Gospel accounts. That kind of turnaround has God's hand all over it.

What Makes the Gospel of Mark Different from the Other Gospels?

Mark writes with urgency. You can read or listen to the entire Gospel in under two hours. He uses the word "immediately" forty times, moving quickly from one event to the next. There is no genealogy, no birth narrative, no political background. Mark gets straight to the point.

In one sentence, he tells us everything we need to know.

What Does Mark 1:1 Actually Mean?

"The beginning of the gospel of Jesus Christ, the Son of God." - Mark 1:1 English Standard Version (ESV)

Every word in that verse carries weight. Let's break it down.

What Does "The Beginning" Mean in Mark's Gospel?

Mark is not simply saying, "Here is where my book starts." He is doing something much more intentional. By opening with "the beginning," he is echoing the very first words of the Bible: "In the beginning, God..." (Genesis 1:1). Just as God was doing something in creation that only He could do, Mark is announcing that God is doing something new again, something that comes not from earth but from above.

This is the beginning of a new creation. And the good news is that Jesus Christ, the Son of God, is the one bringing it. As Paul would later write, if anyone is in Christ, He is a new creation. The old has passed away and the new has come.

What Is the "Gospel" and Where Does the Word Come From?

The word translated "gospel" is the Greek word euangelion, meaning good news. It carries two important backgrounds that Mark's original readers would have recognized immediately.

First, the Old Testament background. The prophet Isaiah announced that God Himself would return, reign in Zion as King, rescue His people, and establish His kingdom. That was the good news Isaiah proclaimed. God was coming to save, to reign, and to restore.

Second, the Roman Empire background. In that culture, "good news" was the language used for imperial announcements, the birth of Caesar, his military victories, his ascension to power. Heralds were sent out to proclaim good news on behalf of Rome.

Mark is doing something bold. He is taking both of those backgrounds and declaring that the true good news is not found in Caesar. It is found in Jesus Christ, the Son of God. The peace, the power, the salvation that Rome could only promise, Jesus actually delivers.

Why Does Mark Call Jesus "Christ, the Son of God"?

Jesus is not simply a first and last name. "Christ" is a title. It means the Anointed One, the Messiah, the one promised throughout the Old Testament. Every covenant promise made to Abraham and David, every word spoken through Isaiah, Jeremiah, and Ezekiel, finds its fulfillment in Jesus Christ.

Mark is saying the wait is over. The promised Messiah has arrived.

And then Mark goes further. He calls Him the Son of God. This is not a claim that Jesus was created or somehow less than the Father. It is a declaration that Jesus possesses the very nature of God Himself. He is fully God, equal with the Father, worthy of all worship, holding all authority in heaven and on earth.

How Does the Rest of Mark's Gospel Support This Claim?

Everything that follows in Mark's Gospel is designed to substantiate that opening declaration. Consider what only the Son of God can do:

• Forgive sins
• Command demons, and have them obey
• Rule over nature, calming storms and walking on water
• Receive worship
• Raise the dead
• Foretell His own death and rise from the grave

Throughout the Gospel, people keep asking the same question: "Who is this?" Mark gives the answer on the very first line. He is Jesus Christ, the Son of God.

There are two great crescendo moments in the book where that truth rises to the surface. Peter declares, "You are the Christ." And at the cross, a Roman centurion looks at the crucified Jesus and says, "Truly this man was the Son of God!" (Mark 15:39 ESV). Mark builds toward those moments from the very first verse.

Why Does It Matter That Jesus Is the Son of God and Not Just a Teacher?

This is where Mark's Gospel becomes deeply personal. Mark is not simply asking readers to find Jesus interesting or to admire His character. He is calling people to believe.

If Jesus were merely a teacher, we could pick and choose which of His teachings to follow. If He were merely a prophet, we could weigh His words alongside others. But if He is the Son of God, then He deserves everything. All of our attention. All of our devotion. All of our worship. All of our obedience. All of our trust. All of our life.

That is the claim Mark is making from the very first sentence.

The One Question Mark Wants You to Answer

As we begin this journey through the Gospel of Mark, there is one question that sits at the center of everything: Who is Jesus?

Mark has already given the answer. He is Jesus Christ, the anointed Messiah, the Son of God. The question is whether we will let that truth settle deep in our hearts and shape how we live.

For those who have not yet placed their faith in Him, the invitation is open. "Everyone who calls on the name of the Lord will be saved." - Romans 10:13 English Standard Version (ESV)

For those who have already trusted in Christ, the call is to live accordingly. As Paul writes, "I appeal to you therefore, brothers, by the mercies of God, to present your bodies as a living sacrifice, holy and acceptable to God, which is your spiritual worship." - Romans 12:1 English Standard Version (ESV)

Life Application

This week, take time to slow down and meditate on one truth: Jesus is the Son of God. In a culture that pulls our attention in a hundred directions, we rarely sit with that reality long enough for it to shape us.

Choose one day this week to read through the Gospel of Mark, or even just the first few chapters. As you read, ask yourself whether the way you are living actually reflects a belief that Jesus is who He says He is. Not just intellectually, but in your priorities, your time, your relationships, and your obedience.

Ask yourself these questions:

• If someone looked at my daily life, would they see evidence that I believe Jesus is the Son of God and not just a good teacher?
• Are there areas of my life where I am treating Jesus as optional rather than as Lord?
• What would it look like this week to offer my life more fully as a living sacrifice to the one who is worthy of everything?
• 
  

The Gospel of Mark begins with a declaration. The question is what we will do with it.
