Christmas is about the incarnation of Jesus. Strip away the season’s hustle and bustle, the trees, the cookies, the extra pounds, and what remains is a humble birth story and a simultaneously stunning reality — the incarnation of the eternal Son of God.
This incarnation, God himself becoming human, is a glorious fact that is too often neglected, or forgotten, amidst all the gifts, get-togethers, pageants, and presents. Therefore, we would do well to think deeply about the incarnation, especially on this day.
Here are five biblical truths of the incarnation.
1. The Incarnation Was Not the Divine Son’s Beginning
The virgin conception and birth in Bethlehem does not mark the beginning of the Son of God. Rather, it marks the eternal Son entering physically into our world and becoming one of us. John Murray writes, “The doctrine of the incarnation is vitiated if it is conceived of as the beginning to be of the person of Christ. The incarnation means that he who never began to be in his specific identity as Son of God, began to be what he eternally was not” (quoted in John Frame, Systematic Theology, 883).
2. The Incarnation Shows Jesus’s Humility
Jesus is no typical king. Jesus didn’t come to be served. Instead, Jesus came to serve (Mark 10:45). His humility was on full display from the beginning to the end, from Bethlehem to Golgotha. Paul glories in the humility of Christ when he writes that, “though he was in the form of God, did not count equality with God a thing to be grasped, but emptied himself, by taking on the form of a servant, being born in the likeness of men. And being found in human form, he humbled himself by becoming obedient to the point of death, even death on a cross” (Philippians 2:6–8).
3. The Incarnation Fulfills Prophecy
The incarnation wasn’t random or accidental. It was predicted in the Old Testament and in accordance with God’s eternal plan. Perhaps the clearest text predicting the Messiah would be both human and God is Isaiah 9:6: “To us a child is born, to us a son is given; and the government shall be upon his shoulder, and his name shall be called Wonderful Counselor, Mighty God, Everlasting Father, Prince of Peace.”
In this verse, Isaiah sees a son that is to be born, and yet he is no ordinary son. His extraordinary names — Wonderful Counselor, Mighty God, Everlasting Father, Prince of Peace — point to his deity. And taken together — the son being born and his names — point to him being the God-man, Jesus Christ.
4. The Incarnation Is Mysterious
The Scriptures do not give us answers to all of our questions. Some things remain mysterious. “The secret things belong to the Lord our God,” Moses wrote, “but the things revealed belong to us and to our children forever” (Deuteronomy 29:29).
Answering how it could be that one person could be both fully God and fully man is not a question that the Scriptures focus on. The early church fathers preserved this mystery at the Council of Chalcedon (451 A.D.) when they wrote that Jesus is “recognized in two natures [God and man], without confusion, without change, without division, without separation; the distinction of natures being in no way annulled by union, but rather the characteristics of each nature being preserved and coming together to form one person and subsistence, not as parted or separated into two persons but one and the same Son and Only-begotten God the Word, Lord Jesus Christ.”
5. The Incarnation Is Necessary for Salvation
The incarnation of Jesus does not save by itself, but it is an essential link in God’s plan of redemption. John Murray explains: “[T]he blood of Jesus is blood that has the requisite efficacy and virtue only by reason of the fact that he who is the Son, the effulgence of the Father’s glory and the express image of his substance, became himself also partaker of flesh and blood and thus was able by one sacrifice to perfect all those who are sanctified” (Redemption Accomplished and Applied, 14).
And the author to the Hebrews likewise writes that Jesus “had to be made like his brothers in every respect, so that he might become a merciful and faithful high priest in the service of God, to make propitiation for the sins of the people” (Hebrews 2:17).
The incarnation displays the greatness of God. Our God is the eternal God who was born in a stable, not a distant, withdrawn God; our God is a humble, giving God, not a selfish, grabbing God; our God is a purposeful, planning God, not a random, reactionary God; our God is a God who is far above us and whose ways are not our ways, not a God we can put in a box and control; and our God is a God who redeems us by his blood, not a God who leaves us in our sin. Our God is great indeed!
