Was Jesus Really Human?

The Short Answer

Yes. Jesus wasn’t God merely wearing a human disguise. The New Testament presents him as genuinely human. He was born, grew, learned, became hungry and tired, experienced human emotions, suffered, and died. He had a real human body and a genuinely human mind, will, and emotional life.

At the same time, the New Testament identifies Jesus as the eternal Son who became human. Historic Christianity therefore confesses him as fully God and fully human. Those two claims create some difficult questions, but I don’t think we solve them by sacrificing either side of what Scripture says.

Key Scriptures

John 1:14 — The eternal Word became flesh and lived among us.
Luke 2:40, 52 — Jesus grew physically and increased in wisdom.
John 4:6 — Jesus became tired from his journey.

John 11:33–35 — Jesus was deeply moved and wept at Lazarus’s tomb.
Mark 13:32 — Jesus said that the Son did not know the day or hour.
Hebrews 2:14–18 — He shared in flesh and blood and was made like his brothers and sisters.
Hebrews 4:15 — Jesus was tempted as we are, yet without sin.
1 Timothy 2:5 — Even after the resurrection, Paul calls him “the man Christ Jesus.”

Jesus Didn’t Merely Look Human

Sometimes Christians defend the deity of Christ so strongly that his humanity almost becomes an afterthought. We say that Jesus is fully God and fully man, but then spend most of our time explaining the “fully God” part.

The New Testament doesn’t do that.

Jesus entered the world through birth. He didn’t arrive as a fully grown visitor pretending to participate in human life. Luke tells us that he grew and increased in wisdom. He became hungry, thirsty, and tired. He experienced compassion, anger, grief, and anguish. He prayed, obeyed, suffered, bled, and died.

Those things aren’t embarrassing qualifications that need to be explained away. They’re part of the incarnation.

The Word became flesh.

In the early church, some people found it easier to believe that a divine Christ only appeared to be human. This eventually became associated with Docetism, from a Greek word meaning “to seem.”

John pushes in exactly the opposite direction. Jesus Christ really came in the flesh. His followers heard him, saw him, and touched him.

So whatever else we mean when we say Jesus is divine, we can’t mean that his humanity was an illusion.

Fully God and Fully Human

Historic Christianity eventually described Jesus as one Person with two complete natures—divine and human.

He isn’t half God and half man. He isn’t a divine Person occupying a human body like someone driving a car. And he isn’t two persons somehow cooperating inside the same body.

The eternal Son genuinely became human without ceasing to be divine.

The Council of Chalcedon in AD 451 tried to establish boundaries for how Christians should talk about this. It didn’t explain the incarnation mechanically—and I’m not sure we should expect a church council to explain how God became man as though it were describing the workings of an engine.

Its point was that Christ’s divine and human natures should be neither confused nor divided.

That distinction matters because Christians have sometimes tried to solve the difficulty by giving up one side or the other.

Docetism protected Christ’s deity by making his humanity less than real.

Apollinarianism taught that the divine Word essentially took the place of a human rational mind in Jesus. He had a human body, but not a complete human psychology.

But what kind of human being has a human body without a human mind?

The Gospels describe Jesus learning, reasoning, making decisions, and submitting his will to the Father.

Other interpretations go in the opposite direction and make Jesus essentially an ordinary human being whom God later adopted or exalted. That certainly preserves his humanity, but then we have to explain the passages that speak of his existence before his human birth.

I don’t think either approach does justice to all the evidence.

How Could Jesus Be Limited If He Was God?

This is where things get more difficult.

If Jesus is God, how could he become tired? How could he learn? How could he not know something?

I think our starting point has to be what Scripture actually says rather than what we think deity must require.

Philippians 2 describes Christ taking the form of a servant and entering the conditions of human existence. The incarnation doesn’t mean that his divine nature stopped being divine. It means that the eternal Son really entered human life.

If every apparent limitation was only an illusion, what would be left of the incarnation?

If Jesus merely pretended to become tired, pretended to experience weakness, and pretended to suffer, then we’re no longer talking about a genuinely human life. We’re talking about a performance.

How Could Jesus Grow in Wisdom?

Luke tells us plainly that Jesus “advanced in wisdom and stature.”

I think we should allow that statement to mean what it says.

Jesus didn’t emerge from Mary’s womb discussing the finer points of the Mosaic Law. He developed as a human child. He learned to speak. He learned about the world around him. He grew intellectually.

How does that human development relate to the Son’s divine knowledge?

I don’t know exactly.

And I don’t think anyone else does either.

Scripture doesn’t give us a psychological diagram of the incarnation showing exactly how divine omniscience and human consciousness operated together in Jesus. We can develop theological models, but eventually we’re describing something for which there is no ordinary human comparison.

What I don’t think we should do is solve the problem by denying something Luke explicitly tells us happened. Jesus grew in wisdom. Any adequate understanding of the incarnation has to make room for that.

Could Jesus Really Be Tempted?

Hebrews says that Jesus was tempted as we are, yet without sin.

Christians have debated what that means for centuries. If Jesus is divine, was it actually possible for him to sin? And if it wasn’t possible, was the temptation real?

I believe Jesus in his humanity could genuinely experience temptation. The fact that he didn’t surrender to temptation doesn’t make the experience meaningless.

We sometimes make the mistake of thinking temptation is only real if there’s a reasonable possibility that the person will give in. But resisting temptation can itself involve suffering.

Hebrews makes that connection. Jesus’ experience of testing is part of the reason he can sympathize with us when we’re tested.

The larger question of whether Christ could have sinned deserves an article of its own.

Did Jesus Remain Human After the Resurrection?

Yes.

The resurrection didn’t undo the incarnation.

After Jesus rose from the dead, he showed the disciples his wounds. He ate with them. He invited them to touch him.

His resurrected body was transformed and no longer subject to death, but it wasn’t discarded.

This is something we can easily overlook. The incarnation wasn’t a thirty-three-year costume God put on and then took off when the mission was finished.

Paul can still refer to the risen and exalted Christ as “the man Christ Jesus” (1 Timothy 2:5).

Jesus remains both divine and human.

Why Does the Humanity of Jesus Matter?

It matters first because that’s the Jesus the New Testament gives us.

Jesus belongs to actual human history. He was born into a Jewish family, circumcised, raised within Israel’s Scriptures, and identified with Israel’s hope for the Messiah. He didn’t hover above human existence. He participated in it.

But his humanity also matters for salvation.

The New Testament presents Jesus as a representative human being. Paul compares Christ with Adam. Adam’s disobedience brought sin and death; Christ’s obedience brings righteousness and life.

Jesus can represent humanity because he genuinely belongs to humanity.

And his humanity means something personally as well.

Jesus knows hunger.

He knows exhaustion.

He knows grief.

He knows rejection.

He knows pain.

He knows temptation.

Not because he observed those things from a distance, but because he entered human existence and experienced them.

Hebrews doesn’t tell suffering Christians, “Don’t worry. Jesus is God, so none of this really affected him.”

It tells us that we have a high priest who can sympathize with our weaknesses because he was tested as we are.

That’s considerably more comforting.

The bodily resurrection also tells us something about God’s purpose for humanity. Christian hope isn’t ultimately that we escape from being human. It’s that human beings are redeemed and raised from the dead.
