The Promise Fulfilled

Texts: Genesis 3:15; Isaiah 7:14; Micah 5:2; Matthew 1:18–25 Big Idea: Christmas is not God improvising; Christmas is God fulfilling. God doesn’t start at the manger. God starts at the beginning.

INTRODUCTION: When Waiting Feels Like Nothing Is Happening

Have you ever waited so long for something that you wondered if it would ever actually happen?

A prayer you’ve prayed for years… A promise you thought God gave you… A season you’re begging God to change… A healing… a relationship… a breakthrough…

Waiting is hard. Waiting can make you wonder:

“Did God forget?”

“Is He still working?”

“Does the promise still stand?”

Israel felt the same way.

Christmas didn’t begin as a holiday. It began as a promise.

A promise God made in the first pages of Scripture and fulfilled in the first pages of the New Testament.

Christmas is God saying:

“I remember. I am faithful. I keep every promise.”

And tonight, we’re going to walk through four major prophecies that show us the real meaning of Christmas.

POINT 1 — THE PROMISE (Genesis 3:15)

Anchor Phrase: Christmas began in the garden.

Read Genesis 3:15.

Genesis 3:15 NIV

And I will put enmity between you and the woman, and between your offspring and hers; he will crush your head, and you will strike his heel.”

The world has just collapsed. Adam and Eve have fallen. Sin has entered. Death has begun. Creation is broken.

And yet before God speaks judgment, before He sends them out of the garden—

He speaks a promise.

JFB says “enmity” means warfare, not fear. FSB says the serpent is not an animal but a divine enemy of God.

And God Himself puts hostility between:

the serpent’s seed —> evil, rebellion, darkness

the woman’s seed —> humanity, God’s people, and ultimately one Man

FSB notes the Hebrew zeraʿ can mean:

one descendant

or many

And that the NT unmistakably identifies Jesus as the ultimate “Seed of the woman” (Luke 3:38; Galatians 3:16).

Then comes the prophecy:

“He shall bruise your head, and you shall bruise His heel.”

JFB explains:

A heel wound is painful but not fatal → Christ’s suffering

A head wound is fatal → Satan’s defeat

Tony Evans adds:

“This is the first prophecy of the virgin birth—He comes from her seed, not Adam’s.”

The gospel starts in Genesis 3.

Before a manger… Before Mary… Before shepherds and angels…

there was a promise that a Savior is coming to crush the serpent and save the world.

Application: You may feel bruised… but in Christ, you will never be defeated.

POINT 2 — THE SIGN (Isaiah 7:14)

Anchor Phrase: God’s promise becomes God’s presence—Immanuel.

Read Isaiah 7:14.

Isaiah 7:14 NIV

Therefore the Lord himself will give you a sign: The virgin will conceive and give birth to a son, and will call him Immanuel.

Ahaz is terrified. Two nations are threatening Jerusalem. God tells him, “Ask for a sign.” Ahaz refuses—not out of humility, but unbelief.

So God says:

“The Lord Himself will give you a sign…”

This is for the house of David (JFB), not just Ahaz.

Then the sign:

“Behold, the virgin shall conceive…”

FSB explains:

Almah = young woman of marriageable age

In Hebrew culture, that assumed virginity

The Septuagint uses parthenos—explicitly “virgin”

Matthew quotes this version purposely

God is not vague. God is precise.

And just like Genesis 3:15 pointed forward, Isaiah 7:14 has:

an immediate fulfillment (Isaiah’s wife and son — Tony Evans),

and a full fulfillment (Jesus — JFB, FSB).

Matthew makes it crystal clear.

Then the name:

“Immanuel” = God with us.

JFB says names in Scripture reveal nature, not a nickname.

Immanuel is not something Jesus is called, it’s something Jesus IS.

Not God above us. Not God near us. Not God watching us. God with us.

Application: Christmas means God steps into your crisis, not away from it. He is with you in fear, with you in pain, with you in questions.

POINT 3 — THE PLACE (Micah 5:2)

Anchor Phrase: God brings greatness out of small places.

Read Micah 5:2.

Micah 5:2 NIV

“But you, Bethlehem Ephrathah, though you are small among the clans of Judah, out of you will come for me one who will be ruler over Israel, whose origins are from of old, from ancient times.”

Bethlehem was tiny.

A village of a few hundred people (FSB).

So insignificant it wasn’t even listed in Joshua or Nehemiah’s city lists (JFB).

Yet Micah says:

“Though you are little… from you shall come forth for Me a ruler…”

JFB points out the tension:

Micah calls Bethlehem “little.” Matthew says it is “not the least.”

Why?

Because God chooses the small to display the great.

JFB:

“God chooses the little things of the world to eclipse the greatest things.”

Micah continues:

“Whose coming forth is from ancient days.”

FSB says this means eternity. Evans says this affirms the King’s preexistence. JFB calls it the strongest Hebrew expression for eternal origin.

Jesus is:

Born in Bethlehem → humanity

From ancient days → divinity

Preaching Line:

“Bethlehem is His birthplace, not His beginning place.”

And then the sovereignty of God shines:

Evans reminds us that God used a Roman census to move Mary and Joseph to Bethlehem.

Caesar thought he was in charge. But God was fulfilling prophecy.

Application: Do you feel small? Insignificant? Overlooked?

Bethlehem says: “God sees you. God chooses you. God uses you.”

God writes His biggest stories in the smallest places.

POINT 4 — THE FULFILLMENT (Matthew 1:18–25)

Anchor Phrase: Jesus is God’s promised plan.

Read Matthew 1:18–25.

Matthew 1:18–25 NIV

This is how the birth of Jesus the Messiah came about: His mother Mary was pledged to be married to Joseph, but before they came together, she was found to be pregnant through the Holy Spirit. Because Joseph her husband was faithful to the law, and yet did not want to expose her to public disgrace, he had in mind to divorce her quietly. But after he had considered this, an angel of the Lord appeared to him in a dream and said, “Joseph son of David, do not be afraid to take Mary home as your wife, because what is conceived in her is from the Holy Spirit. She will give birth to a son, and you are to give him the name Jesus, because he will save his people from their sins.” All this took place to fulfill what the Lord had said through the prophet: “The virgin will conceive and give birth to a son, and they will call him Immanuel” (which means “God with us”). When Joseph woke up, he did what the angel of the Lord had commanded him and took Mary home as his wife. But he did not consummate their marriage until she gave birth to a son. And he gave him the name Jesus.

Matthew calls Mary and Joseph “betrothed”, a legal marriage covenant (JFB, Evans). To break it required divorce.

Mary is “found to be with child”, her pregnancy is showing (FSB).

Joseph, heartbroken, confused, and righteous, chooses:

mercy over humiliation

compassion over condemnation

He plans a quiet divorce.

But then heaven interrupts:

“Joseph, son of David…”

The angel uses the royal title intentionally (JFB). This is about prophecy, not scandal.

“Do not fear… what is conceived is of the Holy Spirit.”

Evans: The virgin birth is God interrupting natural law to accomplish salvation.

Then the mission:

“You shall call His name Jesus… for He will save His people from their sins.”

JFB calls Jesus “the sweetest name to the awakened sinner.” FSB says this name defines the entire Gospel of Matthew.

Jesus didn’t come to:

adjust your morality

inspire your spirituality

clean up your behavior

Jesus came to save you from your sins.

Matthew then quotes Isaiah 7:14:

Isaiah 7:14 NIV

Therefore the Lord himself will give you a sign: The virgin will conceive and give birth to a son, and will call him Immanuel.

“Behold, THE virgin shall conceive…”

Matthew uses the LXX’s parthenos (FSB), showing:

Jesus is the ultimate Immanuel, God with us.

Joseph responds with immediate obedience:

He takes Mary as his wife

He abstains until Jesus is born

He names Him Jesus, fulfilling the angel’s command

Joseph steps into the promise with faith.

CONCLUSION — Christmas Is Promise Kept

From the garden to the prophet’s scroll… From the small town of Bethlehem to the home of a confused carpenter… All of Scripture has been shouting one message:

God keeps His promises.

If God keeps promises over:

centuries

empires

exiles

silence

rebellion

fear

human weakness

Then God can keep His promises to YOU.

Immanuel means:

God with you. God for you. God in you.

You are not forgotten. You are not abandoned. You are not too broken, too sinful, too confused, or too far gone.

Christmas is not about what we give to God. It’s about what God gave to us:

Himself. A Savior. The Promise Fulfilled.

Altar Call

Tonight, that promised Savior can become your Savior

Turn to Him.

Trust Him.

Let the One who crushes the serpent, fulfills the sign, rules from eternity, and saves from sin— save you.

Jesus Christ is:

God with us.

God for us.

God in us.
