Fully God And Fully Man

He was not merely a good teacher, a moral philosopher, or an inspiring prophet. He was fully God and fully man. As God, He possessed all divine authority. As man, He entered our world, experienced our struggles and lived a life of complete obedience to God.

"For there is one God and one mediator between God and mankind, the man Christ Jesus." — 1 Timothy 2:5

From the beginning of human history, God has longed for fellowship with man. Yet sin created a separation that no amount of human effort, religion, morality, or sacrifice could bridge. God, in His love and mercy, provided the only perfect solution: Jesus Christ, the Mediator.

A mediator stands between two parties to bring reconciliation. In the greatest conflict of all—the separation between a holy God and sinful humanity—Jesus alone is qualified to stand in the middle. He does not merely negotiate peace; He accomplishes it through His own sacrifice.

Why Does Humanity Need a Mediator?

God is perfectly holy, righteous, and just. Humanity, however, is sinful by nature and by choice. Because of sin, people cannot approach God on their own.

Throughout the Old Testament, priests served as mediators by offering sacrifices for the people's sins. But those sacrifices had to be repeated continually because they could never permanently remove sin. They pointed forward to Someone greater, the ultimate substitute, and his once-for-all sacrifice on the cross.

Jesus came as the fulfilment of everything those sacrifices represented.

Why Does Jesus Alone Qualify?

Jesus is uniquely qualified to be our Mediator because He is fully God and fully man.

As God, He perfectly reveals the Father and possesses the authority to forgive sins.

As man, He fully identifies with humanity, experiencing temptation, suffering, and death without ever sinning.

He understands God's holiness and humanity's weakness. No prophet, angel, priest, or religious leader could ever occupy this position. Only Jesus could perfectly represent both God and humanity.

Throughout history, humanity has searched for the ideal person—a leader without corruption, a judge without prejudice, a friend without betrayal, and a person without sin. Every generation has produced remarkable men and women, yet every one of them has been marked by weakness, failure, or imperfection.

The Bible presents only one perfect man: Jesus Christ.

He was not merely a good teacher, a moral philosopher, or an inspiring prophet. He was fully God and fully man. As God, He possessed all divine authority. As man, He entered our world, experienced our struggles, and lived the life that no other human being has ever lived—a life of complete obedience to the Father.

The perfection of Christ is not merely something to admire; it is the foundation of our salvation and the example for our Christian life.

Because He is fully God, He perfectly represents God to humanity.

Because He is fully man, He perfectly represents humanity before God.

A. Jesus Christ is fully God

The Deity of Jesus Christ: The Foundation of Our Faith.

There is no greater question that has ever been asked than the one Jesus asked His disciples:

"Who do you say that I am?" (Matthew 16:15)

Everything about our faith rises or falls on the answer to that question.

Many admire Jesus as a wise teacher. Others recognize Him as a prophet, a revolutionary, or an example of compassion. But Scripture presents Him as infinitely more than any of these.

The Bible declares that Jesus Christ is God incarnate—fully God and fully man.

If Jesus is merely another religious leader, then His death was only the tragic death of a good man.

If Jesus is merely a created being, then He cannot save humanity.

But if Jesus is God in the flesh, then every word He spoke carries divine authority, every miracle reveals divine power, and His death possesses infinite value to redeem sinners.

Today we will examine why the deity of Christ is the cornerstone of the Christian faith.

1. Jesus Existed Before Time Began

John 1:1"In the beginning was the Word, and the Word was with God, and the Word was God."

Revelation 19:11-13 (Second coming of Christ)

“And I saw heaven opened, and behold a white horse; and he that sat upon him was called Faithful and True, and in righteousness he doth judge and make war. His eyes were like a flame of fire, and on his head were many crowns; and he had a name written, that no man knew, but he himself. And he was clothed with a vesture dipped in blood: and his name is called "The Word of God”.

2) Jesus claimed equality with God

John 8:58 "Before Abraham was, I AM."

John 10:30 "I and the Father are One."

John 20:28- Thomas Worshiped Jesus

Thomas fell before Jesus and declared,

"My Lord and my God!"

Jesus never corrected him. Throughout Scripture, angels reject worship.

Faithful servants reject worship. Only God accepts worship.

Jesus accepted it because He deserved it.

3) Jesus Possesses the Attributes of God

-He is Eternal- Revelation 22:13

"I am the Alpha and the Omega."

-He is Omnipresent- Matthew 28:20

"I am with you always."

-He is Omniscient -John 2:24–25

Jesus knew what was in every person

-He is Omnipotent

The winds obeyed Him. The sea obeyed Him. Disease obeyed Him. Demons obeyed Him. Death obeyed Him.

Nature recognized its Creator.

-He is Immutable

Hebrews 13:8

"Jesus Christ is the same yesterday and today and forever."

Only God never changes.

4) Jesus Performed the Works of God 

Every star...

Every galaxy…

-Forgiveness of Sins

Mark 2

When Jesus forgave the paralytic, the religious leaders asked,

"Who can forgive sins but God alone?"

Jesus forgave sins because He is God.

-Raising the Dead

John 11:17

"I am the resurrection and the life."

He demonstrated His authority by calling Lazarus from the grave.

5) Jesus Received Worship

Throughout Scripture people worshiped Jesus.

The wise men.

The disciples.

The healed blind man.

Thomas.

The women after the resurrection.

In Revelation, every creature in heaven worships the Lamb.

If Jesus were not God, heaven itself would be committing idolatry.

Instead, heaven glorifies Him forever.

Why Does the Deity of Christ Matter?

Some ask,

"What difference does it make?"

It makes every difference.

a. Only God Could Reveal God

John 14:9

"Whoever has seen Me has seen the Father."

Jesus perfectly reveals God's character.

When we see Jesus loving...

We see God's love.

When Jesus forgives...

We see God's mercy.

When Jesus judges...

We see God's holiness.

b. Only God Could Save Humanity

Human sin is ultimately against an infinitely holy God.

No ordinary human could bear the full weight of divine judgment for the sins of the world.

Because Jesus is fully God, His sacrifice possesses infinite worth.

Because He is fully man, He represents humanity.

He alone bridges the gap between God and sinners.

As Paul writes:

"For there is one God, and there is one mediator between God and men, the man Christ Jesus" (1 Timothy 2:5).

The One Mediator is uniquely qualified because He shares our humanity while possessing the fullness of deity.

c. Only God Deserves Absolute Worship

Jesus is not merely an assistant to God.

He is not an elevated angel.

He is not simply the greatest teacher.

He is Lord.

Every knee will bow.

Every tongue will confess that Jesus Christ is Lord to the glory of God the Father (Philippians 2:9–11).

This confession is not merely intellectual; it is an acknowledgment of His rightful authority over all creation.

B. Jesus Christ Was Fully Human

Throughout church history, believers have defended both truths with equal conviction. If we deny His deity, we lose our Savior. If we deny His humanity, we lose our Mediator.

The incarnation is not simply God appearing to be human. It is the eternal Son of God truly taking on a complete human nature. He did not stop being God, nor did He merely wear a human body like a garment. He became what He had never been while remaining what He had always been.

John writes:

"And the Word became flesh and dwelt among us..." (John 1:14)

1. The Incarnation Was a Real Human Birth

Galatians 4:4

"But when the fullness of time had come, God sent forth His Son, born of woman, born under the law."

Jesus did not suddenly appear as a fully grown man.

He was conceived in the womb of Mary by the Holy Spirit.

He developed as every unborn child develops.

He was born into this world through childbirth.

Luke records His birth in ordinary human terms. He was wrapped in swaddling cloths, laid in a manger, and cared for by His parents.

This reminds us that God did not remain distant from the human condition. He entered it.

His birth also fulfilled God's ancient promises, showing that the Messiah truly came from the family of Abraham and the royal line of David.

The incarnation demonstrates not only God's power but also His humility.

2. Jesus Possessed a Complete Human Nature

Some have imagined that Jesus merely appeared human, but Scripture teaches otherwise.

He had a human body. After His resurrection He said:

"Touch Me, and see. For a spirit does not have flesh and bones as you see that I have." (Luke 24:39)

He possessed a human mind.

Luke tells us:

"Jesus increased in wisdom and in stature and in favor with God and man." (Luke 2:52) 

This does not mean His divine nature lacked wisdom. Rather, in His genuine human experience He grew and learned as every human child does.

He possessed human emotions.

He rejoiced. He loved. He grieved.

He wept at the tomb of Lazarus (John 11:35).

He experienced deep anguish in Gethsemane.

He possessed a human will.

In Gethsemane He prayed:

"Not My will, but Yours, be done." (Luke 22:42)

This prayer reveals His perfect submission to the Father's will in His human nature.

Jesus was not partly human.

He was completely human.

Yet He remained completely without sin.

3. Jesus Experienced the Realities of Human Life

The Gospels repeatedly show us that Jesus shared in the ordinary experiences of humanity.

He became tired.

John 4 tells us that He sat by Jacob's well because He was weary from His journey.

He became hungry.

After fasting forty days in the wilderness, He experienced genuine hunger.

He became thirsty.

On the cross He cried,

"I thirst." (John 19:28)

He slept.

During the storm on the Sea of Galilee, He slept in the boat while the waves crashed around Him.

He knew poverty.

Paul writes:

"Though He was rich, yet for your sake He became poor." (2 Corinthians 8:9)

He experienced rejection.

His own people did not receive Him.

He was misunderstood by His family.

He was betrayed by a disciple.

He was abandoned by His disciples.

He suffered injustice.

He endured false accusations, an unfair trial, mocking, scourging, and crucifixion.

The Son of God entered every dimension of human suffering except sin itself.

4. Jesus Was Tempted Yet Without Sin

Hebrews 4:15

"For we do not have a high priest who is unable to sympathize with our weaknesses, but One who in every respect has been tempted as we are, yet without sin." 

Jesus experienced real temptation.

His sinlessness does not make Him less able to understand our struggles. It reveals the depth of His faithfulness. He endured temptation without yielding to it.

Our temptation comes from two sources:

External temptation (the world and Satan),

Internal sinful desires.

Jesus had the first but not the second.

He never possessed a fallen nature.

He did not have the desire to sin like we all have.

How was Jesus tempted?

This question has been discussed by Christian theologians for centuries. The two main positions are known as peccability (Christ could have sinned, though He did not) and impeccability (Christ could not sin). Both affirm that Jesus never sinned; they differ only on whether sinning was a real possibility.

-The Peccability View: Jesus Could Have Sinned

Hebrews 4:15 says He was "tempted in every way, just as we are—yet without sin."

If there were no possibility of sin, some argue His temptations would not have been fully authentic.

The Impeccability View: Jesus Could Not Sin.

Jesus is God. God cannot sin.

"It is impossible for God to lie" (Titus 1:2).

"God cannot be tempted by evil" (James 1:13, speaking of God's nature).

Jesus' human nature was sinless.

Unlike Adam after the Fall, Jesus did not inherit a sinful nature.

Luke 1:35 says:

"The holy one to be born will be called the Son of God."

He experienced temptation from outside, not from an inward sinful disposition.

He experienced temptation more deeply than we do. We often give in before temptation reaches its greatest intensity. Jesus never yielded, so He endured temptation to its fullest extent.

My Assessment:-

I find the impeccability view more consistent with the whole witness of Scripture.

The reasons are:

Jesus is the eternal Son of God (John 1:1; John 8:58).

God cannot sin.

Jesus' human nature was perfectly holy.

His mission as the spotless Lamb of God required absolute moral perfection (1 Peter 1:19).

The New Testament repeatedly speaks of Him as one "who knew no sin" (2 Corinthians 5:21), "committed no sin" (1 Peter 2:22), and in whom "there is no sin" (1 John 3:5).

Think of two bridges, the first one collapsed when it had a weight test on it but the second one survived though 100% weight was tested on it.

The first bridge never experienced the maximum load because it gave way too soon.

The second bridge experienced the full force because it never failed.

Temptation works in much the same way.

When we give in to temptation, the pressure stops. Once we choose to sin, the struggle is over. We have escaped the pressure—not by overcoming it, but by surrendering to it.

Jesus never surrendered.

We have been given the Holy Spirit as a helper to overcome our sinful nature. When we know that our flesh tempts us to yield to sin, we can lean on to the Holy Spirit to resist the temptation. 

God is not looking for perfect people. He is looking for honest people. God knows our inabilities and weaknesses. What He looks is whether we have a desire to live a pure life and we are availing the heavenly resources to do so. 

In a world full of God haters and compromisers, He placed you and me as His witnesses, who reverence Him, trusting His Word and following them, praying constantly, and avoiding sinful ways.

Because He endured temptation without failing, He is able to help those who are being tempted. He understands the battle—not because He lost it, but because He won it perfectly.

Therefore, Jesus Can Sympathise with Us.
