The Incarnation of Jesus Christ: God With Us
Christian faith does not begin with humanity climbing toward God, but with God coming near to humanity. At the center of that good news stands the incarnation: the eternal Son of God became a real human being without ceasing to be God.
Jesus Christ did not merely bring a message from God. He is God the Son made visible in human flesh. He entered human history, was born of a woman, lived under the law, suffered, died, and rose again. In him, divine glory appeared not as a distant blaze but in a life that could be seen, heard, and touched.
This doctrine is mysterious, but it is not contradictory. Jesus Christ is fully divine and fully human in one person. His incarnation reveals who God is and accomplishes the salvation sinners need.
The Son Existed Before Bethlehem
The life of Jesus did not begin at his conception or birth. The child born in Bethlehem was the eternal Son who had always existed with the Father. John identifies him as “the Word,” the divine person through whom God created all things:
“In the beginning was the Word, and the Word was with God, and the Word was God.
The same was in the beginning with God.
All things were made by him; and without him was not any thing made that was made.” — John 1:1-3
These words establish three essential truths. The Word already existed “in the beginning.” The Word was personally distinct from the Father, for he was “with God.” Yet the Word also fully possessed the divine nature: “the Word was God.”
Jesus is therefore not a created being who later received divine honor. He is the Creator himself. Paul presents the same truth:
“Who is the image of the invisible God, the firstborn of every creature:
For by him were all things created, that are in heaven, and that are in earth, visible and invisible, whether
they be thrones, or dominions, or principalities, or powers: all things were created by him, and for him:
And he is before all things, and by him all things consist.” — Colossians 1:15-17
Here “firstborn” speaks of Christ’s supremacy and rightful authority, not of his being created. All created things came into existence through him and exist for him. Bethlehem was not the beginning of the Son; it was his entrance into human life.
The Word Truly Became Flesh
The incarnation is stated with breathtaking simplicity:
“And the Word was made flesh, and dwelt among us, (and we beheld his glory, the glory as of the only begotten of the Father,) full of grace and truth.” — John 1:14
The phrase “made flesh” means that the eternal Son assumed a genuine human nature. He did not merely put on a visible disguise or temporarily inhabit a human body. He became truly human while remaining truly divine.
His humanity began through the miraculous work of the Holy Ghost in the virgin Mary:
“And the angel answered and said unto her, The Holy Ghost shall come upon thee, and the power of the Highest shall overshadow thee: therefore also that holy thing which shall be born of thee shall be called the Son of God.” — Luke 1:35
Jesus was born, grew, experienced hunger and weariness, suffered bodily pain, and died. His humanity was not an illusion. The apostles encountered him as a real person in history:
“That which was from the beginning, which we have heard, which we have seen with our eyes, which we have looked upon, and our hands have handled, of the Word of life;
(For the life was manifested, and we have seen
it, and bear witness, and shew unto you that eternal life, which was with the Father, and was manifested unto us;)
That which we have seen and heard declare we unto you, that ye also may have fellowship with us: and truly our fellowship
is with the Father, and with his Son Jesus Christ.” — 1 John 1:1-3
The eternal Life was “manifested”—made known in a form that could be heard, seen, and touched. The invisible God had drawn near.
Fully God and Fully Human in One Person
The incarnation did not turn God into a mixture of deity and humanity. Nor did it produce two persons sharing one body. Jesus Christ is one person with two complete natures: divine and human.
As God, the Son is eternal, all-glorious, and the Creator and Sustainer of all things. As man, he possesses a real human body, mind, will, and experience. His deity was not diminished by his humanity, and his humanity was not swallowed up by his deity.
Paul describes the Son’s astonishing humility:
“Who, being in the form of God, thought it not robbery to be equal with God:
But made himself of no reputation, and took upon him the form of a servant, and was made in the likeness of men:
And being found in fashion as a man, he humbled himself, and became obedient unto death, even the death of the cross.” — Philippians 2:6-8
Christ did not cease to be “in the form of God.” Rather, he “took upon him the form of a servant.” His humiliation consisted not in surrendering deity, but in assuming humanity and entering the lowliness, suffering, and obedience of a servant.
This is why Scripture can call Jesus both David’s descendant according to the flesh and the Son of God with power in Romans 1:3-4. The same person is truly human and truly divine.
The incarnation is rightly called a great mystery:
“And without controversy great is the mystery of godliness: God was manifest in the flesh, justified in the Spirit, seen of angels, preached unto the Gentiles, believed on in the world, received up into glory.” — 1 Timothy 3:16
A mystery in Scripture is not nonsense. It is a truth that human reason could never discover unaided but that God has graciously revealed.
Why the Incarnation Matters
The Son became human to reveal God. God is invisible, but the Son makes the Father known:
“No man hath seen God at any time; the only begotten Son, which is in the bosom of the Father, he hath declared
him.” — John 1:18
The expression “only begotten Son” identifies Christ as the unique Son who eternally shares the Father’s divine nature and perfectly reveals him. To see the character of Jesus—his holiness, compassion, truth, authority, and grace—is to encounter the perfect revelation of God.
The Son also became human to redeem those under the law:
“But when the fulness of the time was come, God sent forth his Son, made of a woman, made under the law,
To redeem them that were under the law, that we might receive the adoption of sons.” — Galatians 4:4-5
Notice that God “sent forth his Son.” The Son existed before he was “made of a woman.” He entered the human condition, lived in perfect obedience, and gave himself to redeem sinners.
True humanity was necessary for his saving work. Humanity had fallen into sin, so the Redeemer came as a man. He shared flesh and blood so that he could die, defeat the power of death, and serve as a merciful and faithful high priest:
“Forasmuch then as the children are partakers of flesh and blood, he also himself likewise took part of the same; that through death he might destroy him that had the power of death, that is, the devil;
And deliver them who through fear of death were all their lifetime subject to bondage.
For verily he took not on
him the nature of angels; but he took on
him the seed of Abraham.
Wherefore in all things it behoved him to be made like unto
his
brethren, that he might be a merciful and faithful high priest in things
pertaining to God, to make reconciliation for the sins of the people.” — Hebrews 2:14-17
Only one who is truly human could represent humanity and die. Only one who is truly God could reveal the Father perfectly and provide a sacrifice of immeasurable worth. The incarnation is therefore essential to the gospel.
Misunderstandings the Incarnation Rejects
Several errors must be ruled out clearly.
Jesus did not begin to exist at his human birth. The eternal Word was already with God and was God. The one born in Bethlehem is the Creator entering his creation.
Christ did not cease to be divine. He humbled himself by taking the form of a servant, not by abandoning the form of God. The incarnation is the addition of true humanity, not the subtraction of deity.
Christ did not merely appear human. He possessed genuine flesh and blood. He could suffer and die because his humanity was real. A merely apparent humanity could neither represent human beings nor make reconciliation for their sins.
The Father did not become incarnate. Scripture says that the Father sent the Son. The Father, Son, and Holy Ghost are not interchangeable names for one person. It was specifically the eternal Son who assumed human nature.
Jesus is rightly called Emmanuel:
“Behold, a virgin shall be with child, and shall bring forth a son, and they shall call his name Emmanuel, which being interpreted is, God with us.” — Matthew 1:23
Not the Father made flesh, not a created messenger, and not a divine appearance without true humanity—but God the Son truly with humanity.
Key Takeaways
- Jesus Christ existed eternally before his birth in Bethlehem.
- The Son became fully human without ceasing to be fully God.
- Jesus is one person with a complete divine nature and a complete human nature.
- The incarnation reveals the invisible God in grace, truth, holiness, and glory.
- Christ assumed true humanity so that he could obey, suffer, die, rise, and represent sinners.
- The incarnate Son is the merciful and faithful Savior who brings believers into fellowship with God.
The incarnation invites more than intellectual agreement. It calls for trust, worship, humility, and hope. When God seems distant, look to Jesus Christ, Emmanuel. When guilt presses heavily, remember that the Son took flesh to make reconciliation for sins. When suffering feels lonely, remember that the Savior truly entered human weakness and sorrow. The eternal Son came near, and he remains the perfect revelation of God’s glory, grace, and truth. Draw near to him with confidence: in Jesus Christ, God has truly come to save.
