The Doctrine of the Incarnation: God Became Man
The Doctrine of the Incarnation: God Became Man
The doctrine of the Incarnation stands as the very cornerstone of Christian faith, proclaiming the profound and awe-inspiring truth that the eternal, omnipotent God condescended to take upon Himself human flesh, becoming man without ceasing to be God. This is not merely a theological concept but the central historical event that forever altered the course of human history and secured the hope of salvation for fallen humanity. To deny the Incarnation is to dismantle the very foundation of the Gospel, for without God becoming man, there could be no perfect sacrifice, no bridge between a holy God and sinful humanity, and no mediator to reconcile the two. The King James Version of the Bible unequivocally declares this miraculous union, presenting Jesus Christ as both fully God and fully man—a mystery that transcends human comprehension yet is essential for our redemption.
The Pre-existent Deity of Christ
Before His advent into the world as a babe in Bethlehem, Jesus Christ existed eternally as the second Person of the Godhead, co-equal and co-eternal with God the Father and God the Holy Ghost. He was not a created being, nor did His existence begin at His birth. The Scriptures bear witness to His divine nature and pre-existence, establishing His absolute deity before the Incarnation.
In the beginning was the Word, and the Word was with God, and the Word was God.
This "Word" is unequivocally identified as Jesus Christ. He is not merely a prophet or a good man, but God Himself. Furthermore, His role in creation underscores His divine attributes:
All things were made by him; and without him was not any thing made that was made.
The Apostle Paul reinforces this truth, declaring Christ's active involvement in the very fabric of existence:
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.
Jesus Himself asserted His eternal pre-existence, claiming a timeless identity that shocked His Jewish listeners:
Jesus said unto them, Verily, verily, I say unto you, Before Abraham was, I am.
The phrase "I AM" directly echoes God's self-revelation to Moses in Exodus 3:14, a clear declaration of His divine, self-existent nature. The Incarnation, therefore, was not the beginning of Christ's existence, but the beginning of His human experience, wherein He, being God, willingly took on the form of a servant.
The True Humanity of Christ
While fully God, the Incarnation means that Jesus Christ also became fully man. This was not a mere appearance of humanity (Docetism), but a true and complete assumption of human nature, including a human body, soul, and spirit. This profound truth is revealed through the miraculous virgin birth.
Now the birth of Jesus Christ was on this wise: When as his mother Mary was espoused to Joseph, before they came together, she was found with child of the Holy Ghost.
The angel Gabriel's words to Mary confirm the divine origin of His humanity:
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.
The Apostle John concisely summarizes this mystery:
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.
Jesus experienced the full range of human emotions and limitations (apart from sin). He hungered (Matthew 4:2), thirsted (John 19:28), grew weary (John 4:6), wept (John 11:35), and suffered pain unto death. The book of Hebrews emphasizes the necessity of His full humanity for His role as our 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.
His true humanity allowed Him to truly represent mankind, to suffer as man, and to die as man, thus making His sacrifice effective for human beings.
The Hypostatic Union: One Person, Two Natures
The Incarnation is not merely that God visited humanity, or that a man became God, but that in the single person of Jesus Christ, two distinct natures—perfect deity and perfect humanity—are inseparably united without confusion, mixture, or change. This is known as the Hypostatic Union. He did not become half-God and half-man, nor did His divinity absorb His humanity or vice versa. He remained fully God and became fully man, simultaneously.
The Apostle Paul succinctly states this profound truth:
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.
Here, "God was manifest in the flesh" directly points to the Incarnation. Colossians further emphasizes the fullness of the Godhead dwelling in Him bodily:
For in him dwelleth all the fulness of the Godhead bodily.
This means that all the attributes of God—omnipotence, omniscience, omnipresence, eternality, immutability—resided fully in the man Jesus. Simultaneously, He possessed all the essential attributes of humanity—a body, a soul, a mind, emotions—apart from sin. He could perform miracles as God and yet grow weary as man. He could know the thoughts of men as God and yet ask questions as man. The two natures acted in perfect harmony through His one person, never diminishing or corrupting the other.
The Purpose of the Incarnation
The Incarnation was not an arbitrary act but a divinely purposed event, essential for the execution of God's redemptive plan. Its purposes are manifold:
No man hath seen God at any time; the only begotten Son, which is in the bosom of the Father, he hath declared him.
Jesus Himself declared, "He that hath seen me hath seen the Father."
For he hath made him to be sin for us, who knew no sin; that we might be made the righteousness of God in him.
For we have not an high priest which cannot be touched with the feeling of our infirmities; but was in all points tempted like as we are, yet without sin.
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;
Seeing then that we have a great high priest, that is passed into the heavens, Jesus the Son of God, let us hold fast our profession. Let us therefore come boldly unto the throne of grace, that we may obtain mercy, and find grace to help in time of need.
Implications for Believers
The doctrine of the Incarnation carries profound implications for every believer:
- Assurance of Salvation: Because Jesus was fully God, His sacrifice has infinite value, sufficient to atone for all sin. Because He was fully man, He could truly die and represent us. His death on the cross was not merely the death of a good man, but the death of God in human flesh, making His sacrifice truly efficacious for our redemption.
- Understanding God's Love: The Incarnation is the ultimate demonstration of God's immense love for humanity. He did not send an angel or a prophet, but came Himself in the person of His Son, enduring hardship, suffering, and death for our sakes. John 3:16 declares, "For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life."
- Our High Priest Intercedes: We have a sympathetic High Priest who understands our temptations and weaknesses, having experienced them Himself (yet without sin). We can approach God with confidence through Him.
- Hope of Resurrection and Glorification: Christ's Incarnation, death, and resurrection are the pattern and promise of our own future resurrection and glorification. As He took on human flesh and glorified it, so too will those who are in Him be raised with glorified bodies.
Conclusion
The Incarnation is not an abstract theological concept but the pulsating heart of the Christian faith. It is the miraculous, indispensable truth that the eternal, uncreated God, out of boundless love, entered His own creation, taking on perfect humanity in the person of Jesus Christ. He is not two persons, but one Christ, both God and man, simultaneously and inseparably. This unique union enabled Him to live a sinless life, offer a perfect atonement for sin, conquer death and the devil, and reveal the Father fully. Without the Incarnation, there is no Gospel, no salvation, and no hope. Therefore, let us cling to this glorious doctrine, worshipping Him who is our great God and Saviour, Jesus Christ, truly God manifest in the flesh.
