Matthew 1: Why a Virgin Birth?

About This Episode

Why is a virgin birth important? What's on the line if Jesus had a physical dad? And what does it mean for Jesus to be called Emmanuel, God with us? Seth and David continue their journey to read their Old Testament like Matthew does, and try to figure out why it's good news that Jesus was born of a virgin.

Why a Virgin Birth? Matthew 1 and the New Creation

Show Notes

David Bowden and Seth Stewart continue their journey through the Book of Matthew, turning their attention to the birth narrative of Jesus in Matthew 1:18-25. This episode explores why Matthew frames the Messiah's conception as nothing less than a new creation—and what that means for everyone who reads the story today.

The Genesis of Jesus

Matthew's telling of Jesus' birth does more than recount history. The Greek word he uses for "birth" in Matthew 1:18 is the same word that gives the first book of the Bible its name: genesis. This word choice is intentional. Matthew wants his readers to think not just about the arrival of a baby, but about the creation of a world. When the Spirit of God hovered over the formless void in Genesis 1, life emerged from nothing. Now, when the Holy Spirit comes upon Mary—a virgin whose womb represents that same emptiness—new life emerges again.

The parallels run even deeper. In Genesis, after God creates the world, He fashions Adam from the dust, puts him to sleep, and when Adam awakens, he finds his bride. In Matthew's account, after the Spirit brings life into Mary's womb, Joseph falls asleep, receives a dream, and upon waking takes Mary as his wife. Matthew has constructed a miniature retelling of creation within the birth story. Whatever is happening with this small family, he suggests, represents the recreation of the entire world. A new world order is emerging.

Salvation from the Outside

The virgin birth is more than a miraculous event—it is a theological statement about how God saves. Throughout history, humanity has attempted to secure its own righteousness and relationship with God through political power, technological achievement, and reproduction. Generation after generation, people have tried to build their way to blessing, but these efforts have only perpetuated the same patterns of sin and exile that began in the garden of Eden. Every child born through normal human means has been born into this broken system.

But in Jesus, God breaks the cycle. Salvation comes not from within humanity but from the outside. Just as God spoke life into being at creation, without any pre-existing material to work with, so now God brings salvation ex nihilo—out of nothing. Mary contributes no male agency to this conception. The Holy Spirit does the work. This is good news precisely because it means our salvation does not depend on human ingenuity or effort. God does not need our contribution to accomplish what He has planned. The virgin birth declares that the old way of doing things—the endless striving that always leads back to sin—has been interrupted by something entirely new.

Immanuel: God With Us in a New Way

Matthew applies the prophecy of Isaiah 7:14 to Jesus: "The virgin will conceive and give birth to a son, and they will call him Immanuel—which means, 'God with us.'" This name has always been true of Yahweh. He was with Israel in the fire and cloud, in the parting of the Red Sea, in the tabernacle and temple. But when God is born of a woman, "God with us" takes on a meaning it has never had before.

In Genesis, God's breath animated Adam, creating a human being distinct from God himself. But in Jesus, the Holy Spirit comes upon Mary and the result is God himself in human form. There is no distance between divinity and humanity in Jesus. The hope of the entire Old Testament—that God might truly dwell with His people—finds its fullest expression not in a temple or a presence, but in a person. What God prefigured when He breathed life into the dust of the earth, He now completes by breathing His Spirit into a woman's womb to produce the Son of God.

The Sign of Judgment and Deliverance

To understand why Matthew quotes Isaiah's prophecy, we need to understand its original context. In Isaiah 7, the wicked King Ahaz faces a political crisis: the leaders of northern Israel are threatening to invade Jerusalem. The prophet Isaiah offers Ahaz a sign that God will deliver Judah—a young woman will conceive and bear a son, and before that child grows up, Ahaz's enemies will be destroyed. Isaiah himself fulfills this prophecy by fathering a son named Maher-Shalal-Hash-Baz, whose name means "swift is the plunder." And indeed, Assyria soon defeats Judah's enemies.

But the sign comes with a catch. Ahaz, in false piety, refuses to ask God for confirmation. And because of his half-hearted faith, God turns Assyria against Judah as well. The sign of deliverance becomes a sign of judgment against faithless leadership. Matthew sees this pattern repeating. Jesus is born, and the sign of a virgin birth is given. But soon we meet King Herod—another Jewish ruler who will dismiss the sign and face judgment for his rejection. The virgin birth signals both the defeat of God's people's true enemy (sin itself) and the judgment that falls on leaders who refuse to believe.

Why Jesus, Not Just Any Child

Matthew shifts the meaning of Isaiah's prophecy in a crucial way. In Isaiah, the child's name signals military victory: God is with us to defeat our political enemies. But in Matthew, the angel tells Joseph to name the child Jesus, "because he will save his people from their sins." The real enemy is not Assyria or Rome. It is the sin that has plagued every human attempt to live with God since the garden.

This is why Mary's virginity matters so much. If Jesus were simply another child born through normal means, he would be just another link in the long chain of human effort to produce a savior. But a child conceived by the Holy Spirit alone represents something the world has never seen: God's salvation coming entirely from outside the broken system. No genealogical claim, no political dynasty, no human achievement can take credit for what God accomplishes in Jesus. The virgin birth is the sign that sin's reign is ending—not through our striving, but through God's gracious intervention.

Reading the Signs Like Joseph

Joseph stands in sharp contrast to King Ahaz. When the angel gives him a sign, he does not dismiss it. He wakes from his dream and does exactly what he is told. He takes Mary as his wife but does not consummate the marriage until Jesus is born. This detail is not incidental. Joseph seems to have read the Book of Isaiah carefully. He noticed that when Isaiah was told to name his son, God did not command him to conceive that son—Isaiah took that step on his own. Joseph, perhaps learning from Isaiah's example, refuses to act where God has not spoken. He trusts that God is doing something new and refuses to insert his own agency into the work.

The invitation for readers today is the same. The Old Testament is filled with signs pointing to Jesus—not merely to prove that He is the Messiah, but to show us who He is and what He came to accomplish. These signs are like loaded guns placed over a mantelpiece in the opening act of a story, waiting to fire in the climax. Matthew shows us that the entire history of Israel is a prototype for the salvation of the universe. We can respond like Ahaz and Herod, dismissing the signs in false piety or political calculation. Or we can respond like Joseph, paying careful attention to what God is doing and trusting that He is accomplishing something far greater than the simple play-by-play of history.
