Zechariah’s Song | The Covenant Remembered
Before Luke brings us to Bethlehem, he takes us somewhere older. Before the manger, before the shepherds, before the Bethlehem star ever rose, there were songs—ancient, aching, Jewish songs—carried through centuries of silence.
Many Christian Advent traditions begin with inward reflection, wrapped in candlelight and ringing with carols. But Luke begins with the songs of a priest, a mother, a prophet, and a widow—voices who knew the promises long before we sang the carols.
This is Advent as Scripture tells it. A Messianic Advent explores the first songs of the Messiah’s coming through the eyes of those who waited — and still wait — for Israel’s redemption.
Luke 1:68–79
The Silence and the Song
An old priest stood in the temple, the scent of incense curling through the air.
For centuries, heaven had been silent. No prophets. No visions. No fresh word from the God of Israel. Only the faint echo of ancient promises—unbroken, but waiting.
Then the silence was pierced.
Zechariah saw an angel standing beside the altar of incense. The message was impossible: his barren wife, Elizabeth, would bear a son—a child who would restore the hearts of Israel to their God and prepare the way for his anointed one. But faith can falter, even in the most faithful places. And Zechariah, like so many before him, could not believe. “Too old,” he said. “Too late.”
He walked out of the temple unable to speak—a priest silenced by his own unbelief. A priest appointed to bless could no longer bless. A mouth meant to proclaim God’s mercy was shut.
Months passed. Elizabeth swelled with life.
And when the child was born, the silence broke again—but this time into faithful praise. Zechariah’s tongue, once stilled, was loosed by God’s mercy. So it’s fitting that his first words were not about himself, or even about the little miracle in his arms. They were about God and about Israel—about a story still alive.
This is where Luke begins Advent. Not in Bethlehem, but in the temple. Not with shepherds, but with an old priest and a covenant refusing to die.
The God Who Remembers
“Praise be to the Lord, the God of Israel, because He has visited and redeemed His people.”
Before Jesus was born, Zechariah held his own son and saw more than a miracle—he saw a promise remembered. For generations, heaven had been silent, the temple corrupt, and Rome’s shadow heavy upon the people. Yet even then, God had not forgotten.
The old priest knew the story of redemption began beneath Canaan’s stars, when God swore to Abraham a family, a land, and a future. It has always been a Jewish story—holy, particular, a fierce tale of faithfulness and folly. Through wilderness and exile, covenant and kingship, lament and longing, God’s promise endured.
As Zechariah watched John’s first breaths, he realized Israel’s covenant was breathing again. His son would not prepare the way for a generic Savior, but for Israel’s deliverer—the Son of David through whom light would rise and spill outward, until even the nations stood within its glow.
“He has raised up a horn of salvation for us in the house of His servant David.”
Mercy and Memory
The days Zechariah lived in—and the season of Jesus’s birth—were not bright ones for Israel. The people, the land, the covenant family had known failure, compromise, and long centuries of suffering.
So why act now? Why remember them again?
“To show mercy to our ancestors and to remember his holy covenant, the oath he swore to our father Abraham...”
Mercy and memory—these are the heartbeats of Zechariah’s song. And they remain the heartbeats of Christmas today.
The mercy Zechariah sang of was not about God’s mercy towards sinners. It was for people we have only ever read about, people long gone by our own time—Abraham, Isaac, and Jacob. It was God’s mercy that remembered the covenant he swore to them long before our nativity scenes and Advent wreaths, long before the manger and the star.
Zechariah’s song is not a lullaby; it is prophecy. His joy is not anchored in vague hopes of “peace on earth” or “forgiveness of sins” or even in the loosing of his own tongue, but in the restoration of a nation—the mercy God promised to their fathers, stirring again in his generation.
“We have been rescued from our enemies
so we can serve God without fear,
in holiness and righteousness
for as long as we live.”
In the days before Jesus’s birth, Zechariah sang the eternal vows of a relationship God refuses to let fail.
And in the days before we celebrate his birth, we are invited to sing those same songs too.
Advent Reflection: The Promise Remembered
At Christmas, it’s easy to be swept up in our beloved traditions—wintery waiting, sentimental starlight, and familiar hymns that celebrate a Savior born to save us. But I fear that if Zechariah walked into one of our Christmas Eve services and sang his song, few of us would understand him. He didn’t sing about Jesus coming to save “the world” or to comfort “every heart.”
He sang about God keeping his covenant with Israel—the foundation on which everything else stands.
Before we rush to “good news for all people,” Scripture calls us to listen to the song that came first—the song of mercy to the fathers and the covenant God swore to Abraham. Before our carols lift up universal hope, Zechariah sings of promises spoken to a particular people, in a particular land, through whom God would someday send blessing to the nations.
Zechariah’s song is not the beginning of a new story; it is the continuation of a very old one. One we still have a chance to learn.
Christmas brings joy and generosity, beauty and nostalgia. But Zechariah’s story warns us as much as it invites us. We can be just like him—slow to believe that God can still do what He has promised, especially through the people or the places we’ve already decided are too barren, too broken, too late.
But the old priest learned what Advent always teaches—and what we modern readers often miss: God’s promises do not expire—not with silence, not with age, and not with our unbelief.
Of John, his father said:
“And you, my little son,
will be called the prophet of the Most High,
for you will prepare the way for the Lord,
to give His people knowledge of salvation
through the forgiveness of their sins.
Because of God’s tender mercy,
the morning light from heaven is about to break upon us,
to give light to those who sit in darkness and in the shadow of death,
and to guide us to the path of peace.”
And by that same mercy, the rising sun has already broken upon us, too. Its warmth has reached even our hearts, stirring faith in the God who has not given up on his plan for shalom.
This Advent, as we celebrate the birth of Israel’s redeemer, the same mercy that loosed Zechariah’s silence can also shatter ours. A baby in his arms, another yet to be born; a child already given for a people who do not yet recognize him. The birth of the Messiah stirs our faith and lifts our song—not only in celebration of what we have received, but in awe of the God who keeps his word.
And so, as we sing our carols and rejoice in the birth of the King of the Jews, may the song of the old priest still haunt our hearts:
Christmas is the covenant kept,
a promise remembered,
and the light of God’s tender mercy
falling upon all of us who have stood in our own unbelief.
This reflection is part of A Messianic Advent, a five-part series tracing the songs and voices surrounding the Messiah’s birth. Up next: Mary’s Song | The Promise Made Flesh.
