The Dual Nature of Jesus Christ

1 Timothy 3:16, “And without controversy great is the mystery of godliness: God was manifest in the flesh…”

The great mystery is not that there are three divine persons in heaven. The great mystery is that the one invisible God stepped into visibility, took on real humanity, and revealed Himself to us in the man Christ Jesus.

John said:

1 John 4:1-3, “Beloved, believe not every spirit, but try the spirits whether they are of God…Every spirit that confesseth that Jesus Christ is come in the flesh is of God: And every spirit that confesseth not that Jesus Christ is come in the flesh is not of God: and this is that spirit of antichrist…”

2 John 1:7, “For many deceivers are entered into the world, who confess not that Jesus Christ is come in the flesh.”

So plainly, The spirit of antichrist is any spirit, teaching, influence, or doctrine that denies, diminishes, distorts, or replaces the true identity of Jesus Christ. The spirit of antichrist attacks the truth of who Jesus is. Because if the enemy can change who Jesus is, he can change the gospel, worship, salvation, baptism, prayer, and doctrine.

How do you test the spirit?

1 John 4:1 says, “Believe not every spirit, but try the spirits whether they are of God…”

That means do not accept every voice just because it sounds spiritual. Test it by truth…Test what it says about Jesus.

The Humanity of Jesus Christ:

Jesus Was Truly Human

Before we declare His deity, we must not deny His humanity. Jesus was not pretending to be a man. He was not God wearing humanity like a costume. He became genuinely human. Jesus did not just “dress up” as a man.He actually became man.

John 1:14, “And the Word was made flesh, and dwelt among us…”

It does not say the Word “appeared like flesh.”It says the Word was made flesh.

That means Jesus had a real human body, real human emotions, real human hunger, real human tiredness, real human development, and real human suffering.

The Bible gives many proofs of His real humanity.

• Then Luke 2:52 says, “And Jesus increased in wisdom and stature…”

He did not appear on earth as a full-grown man merely looking human. He came through the womb. He was born. He was wrapped in swaddling clothes. He had to be carried. He had to be fed. He had to learn to walk. He had to grow in stature.

But the verse says more than that. It says He also increased in wisdom. That means, according to His humanity, Jesus experienced real human development. He learned. He matured. His human mind developed.

This does not mean His deity was ignorant. God knows all things. But in His humanity, Jesus submitted to the process of growth. The eternal God entered time.The all-knowing God took on a human mind that could learn.The One who created childhood became a child.The One who designed growth submitted Himself to growth... He did not skip the process

• Matthew 4:2, “... He was afterward an hungred.”

Hunger is one of the most basic proofs of humanity. Angels do not need bread. Spirits do not feel their stomachs ache. But Jesus felt hunger. He allowed His own body to feel emptiness in the wilderness.

Jesus knew hunger. That means His body was real. He did not come as a distant God giving instructions from the sky. He came close enough to feel what we feel.

• Matthew 8:24, “But he was asleep.”

Jesus knew exhaustion. He slept because His humanity became tired. Think about that... Jesus slept --The One who neither slumbers nor sleeps, according to Psalm 121:4, entered a human body that needed sleep.

As God, He never slumbers.As man, He slept in the boat… That is not contradiction. That is incarnation. He slept because His humanity was real. His body became tired. His eyelids became heavy. He entered the same human rhythm of work, exhaustion, and rest.

But what happened next? The disciples panicked because of the storm. Jesus woke up and rebuked the winds and the sea.

So in one scene, you see both natures -- Sleeping in the boat shows His humanity. Rebuking the storm shows His deity. The man was asleep. But God was still in the boat.

That is why the disciples asked, “What manner of man is this, that even the winds and the sea obey him!” --- They were beginning to realize: this is not an ordinary man. This is a real man, but more than a man. This is God manifest in flesh.

• John 4:6, “Jesus therefore, being wearied with his journey, sat thus on the well.”

He knew weariness. The Creator of the universe sat tired beside a well. That verse is full of wonder! The Creator of the earth sat tired on the earth He created. The One who formed the rivers sat beside a well. The One who gives living water had a body that felt the weight of walking under the heat of the day.

He was weary... Not pretend-weary...Not symbolically weary -- Actually weary. So do not rush past His weariness. It tells us His humanity was real. But do not stop at His weariness either, because the weary man was still the well of salvation.

• John 11:35, “... Jesus wept.”  

This may be the shortest verse, but it is one of the deepest windows into the humanity of Christ. He was human enough to feel grief. Jesus stood at the tomb of Lazarus and cried...He wept! Why? Because real humanity feels grief. That means Jesus did not only come to conquer death from a distance. He came close enough to feel the pain death causes... He wept with those who wept.

But then He cried, “Lazarus, come forth.” Again, both His natures appear. He wept as man. He raised the dead as God; His tears proved He was human -- His voice proved He was divine; The same eyes that cried had the authority to command a dead man to live.

• Luke 22:44, “And being in an agony he prayed more earnestly…”

He knew emotional pressure, agony, and deep earnestness in prayer. That phrase “being in an agony” is important. Jesus was not just uncomfortable -- He was under crushing pressure. Gethsemane was not ordinary sorrow. It was not nervousness before pain. It was the sinless humanity of Jesus standing at the edge of Calvary, feeling the weight of the cup He was about to drink.

Gethsemane shows us how real His humanity was. The mighty God in flesh did not walk to the cross mechanically. He did not face suffering like a stone statue. His human soul felt the approaching weight. His body responded to the burden. His prayer became more earnest. The pressure was so intense that His sweat became “as it were great drops of blood.” -- That means His body was reacting to the inward agony, the battle inside Him was so severe that it showed outside Him. This is powerful because Jesus had no sin of His own; He was not afraid because He was guilty. He was not trembling because He had failed. He was the spotless Lamb. But He was about to stand in the place of sinners. He was about to bear what He never committed.

2 Corinthians 5:21, “For he hath made him to be sin for us, who knew no sin…”. --That is why Gethsemane is so deep. The sinless One was preparing to carry sin. The Holy One was preparing to touch the uncleanness of the world. The Life-giver was preparing to enter death. So His sweat was not just sweat. It was the outward evidence of inward pressure.

He was not playacting humanity. His human body was under real stress. His nervous system, His emotions, His flesh, His blood, His sweat glands — all of it belonged to real humanity.

He knew what it was to feel pressure in the body.He knew what it was to wrestle in prayer. He knew what it was to be overwhelmed and still surrender. He knew what it was to say, “Not my will, but thine, be done.”

Hebrews 4:15 “For we have not an high priest which cannot be touched with the feeling of our infirmities…”

He can be touched with the feeling of our infirmities because He truly entered human weakness. The sweat in Gethsemane is telling us, His humanity was real. His suffering was real. His obedience was real. His sacrifice was real. -- Jesus was not performing redemption.He was purchasing it. He was man enough to feel the agony.He was God enough to fulfill the mission.

• 1 Corinthians 15:3, “Christ died for our sins…”

This is the greatest proof that His humanity was real. God as eternal Spirit cannot die. The divine nature is immortal. But Jesus had a real human body that could suffer, bleed, and die. He did not pretend to die, He did not appear to suffer, He did not stage a crucifixion.

He truly died... The nails entered real hands, The thorns pierced a real brow,The whip tore real flesh,The blood was real blood.The breath that left His body was real human breath.

And yet, we must say it carefully: We do not say God ceased to exist. We do not say deity died. But we do say the One who died was the mortal flesh.

That is the mystery -- The immortal God took on mortal flesh so He could die for mortal men.

He took a body that could hunger, He took a body that could grow tired, He took a body that could sleep, He took a heart that could grieve, He took a human life that could develop, He took flesh that could bleed, He took a body that could die.

Why? Because without real humanity, there could be no real sacrifice.

A pretend body cannot carry real sin.A fake humanity cannot pay a real debt.

So Jesus had to be truly man…

But if He were only man, His death would not be enough to save the world. So He had to be more than man.

He had to be man enough to die, but God enough to save.

Man enough to touch our weakness. God enough to destroy our bondage.

Man enough to stand in our place. God enough to reconcile us to Himself.

Man enough to shed blood. God enough to make that blood eternally powerful.

That is why the incarnation matters.

Jesus was not God just wearing humanity like a robe and then removing it when the work was done... He became truly human. He entered the full reality of human life, yet without sin.

The incarnation was not God pretending to be like us; it was God becoming one of us so He could save us.

That is why Hebrews 2:14 says: “Forasmuch then as the children are partakers of flesh and blood, he also himself likewise took part of the same…”

That phrase is powerful: “he also himself likewise.” -- In other words, because we had flesh and blood, He took flesh and blood. He entered the same human condition.Not with sin… But with real flesh. Real blood, Real suffering, Real obedience, Real death.

So when we preach the humanity of Jesus, we are not making Him less divine. We are showing how far God was willing to come to redeem us.

The wonder is not that Jesus looked human. The wonder is that the mighty God truly became human.

Isaiah 9:6: The child born was also the mighty God.The Son given was also the everlasting Father. The man on the cross was also the Lord of glory. So yes, we must say clearly: Jesus was truly man... But we must not stop there. Because Jesus Was Not Only Man — He Was God. A half-truth about Jesus can become a dangerous error.

To say, “Jesus was a man,” is true. But to say, “Jesus was only a man,” is false.

Jesus was as genuinely God as He was genuinely man.
