Salvation is not merely forgiveness. The child born to Mary is also Immanuel (Matt 1:23). Sin separated humanity from God’s presence; to restore God’s presence, sin first had to be dealt with. The incarnation begins the saving work that removes the barrier between God and humanity. John says the Word became flesh and “made his dwelling among us.” In Jesus, God’s presence is no longer only symbolised in the tabernacle or temple; God comes among us personally in the Son. We see his glory, full of grace and truth (Jn 1:14). Through Jesus’ incarnate saving work, believers receive the Spirit as God’s abiding presence, and the Father and the Son make their home with them (Jn 14:17, 23).

Mahesh grew up within another faith tradition where stories of divine beings appearing throughout history were common—some as kings, others as animals, others as wise teachers who completed their task and returned to the divine realm. So when he heard Christians speak about Jesus, he smiled and told his believing uncle:

“Jesus is also one kind of incarnation. Our faith has many. There is no great difference.”

His uncle did not argue. He gently replied:

“Mahesh, may I show you why the Christian understanding of incarnation is unlike anything else in the world?”

What follows is the heart of their conversation—the truth Scripture proclaims about the uniqueness of Jesus’ coming.

A Real Incarnation in Human History

Unlike the mythical or symbolic settings familiar to Mahesh, Scripture places Jesus’ coming firmly within human history. Luke names Nazareth in Galilee, a virgin named Mary, and Joseph of David’s royal line (Lk 1:26–28). These were real people in real places. The stories Mahesh heard were not tied to dates, locations, or eyewitness testimony.

Nor does Jesus simply appear without preparation. His coming fulfils promises God made centuries earlier. God promised that the seed of the woman would crush the serpent (Gen 3:15), that through Abraham’s offspring all nations would be blessed (Gen 12:3). Mary is called a virgin at the moment of announcement, echoing Isaiah’s prophecy that a virgin would conceive and bear a son (Isa 7:14). Jesus enters the world as the promised Messiah, fulfilling God’s covenant that a son of David would reign forever (2 Sam 7:13–14).

The incarnation is therefore not a legend attached to history. It is God fulfilling his promises within history. But if Jesus truly enters history in fulfilment of God’s promises, the next question is clear: who is this child? 

A Revealed Identity Rooted in Eternity

In the stories Mahesh knew, the meaning of a divine appearance was usually understood only after the meaning of the story had unfolded. A figure would appear, confront evil, restore order, or complete a task, and only then would people recognise who that figure was and what the appearance meant. Scripture tells a very different story.

Before Jesus is conceived, Gabriel announces who he is: Jesus—“the Lord saves”—the Son of the Most High whose kingdom will never end (Lk 1:31–33). His identity reaches much further back than Bethlehem. John identifies him as the eternal Word who was with God, was God, through whom all things were made (Jn 1:1–3). The Word did not begin at the manger. The Word became flesh and made his dwelling among us (Jn 1:14).

Jesus’ identity is not discovered after the event or inferred from what he accomplishes. It is revealed by God before his birth and rooted in eternity. He enters history as the eternal Son whom the Father has already revealed.

But this raises another question: how can the eternal Son enter human history without ceasing to be who he is? 

The Eternal Son Made Like Us

Mahesh thought of incarnation as a divine figure coming for a period of time to deal with a particular evil before returning to a heavenly abode. But Scripture presents something far greater: the eternal Son did not merely appear on earth, a divine manifestation; he was conceived by the Holy Spirit, born of the virgin Mary, and truly became human.

Isaiah foretold that a virgin would conceive a son called Immanuel—“God with us” (Isa 7:14). When Mary asked how this could be, Gabriel explained that the Holy Spirit would come upon her, the power of the Most High would overshadow her, and the child would be the holy Son of God (Lk 1:34–35).
