Sermon draft: The Light Has Come
Main passage: Isaiah 9:2–7
Big idea: Because God has given us Jesus, the Light who breaks darkness and reigns forever, we can have real hope even while we wait.
Introduction
There is a particular kind of darkness that comes when you can see just enough to know what is around you, but not enough to know where to go.
Perhaps you have walked through a house at night and thought you knew the way—until your foot found the corner of a chair. Or perhaps you have driven in heavy fog, slowing down because the road ahead has disappeared. In those moments, you do not need someone to tell you that the darkness is not so bad. You need light. You need to see the way forward.
The Bible speaks about a darkness deeper than a dark room or a foggy road. It is the darkness of a world under the shadow of sin and death: people alienated from God, wounded by evil, burdened by injustice, and unable to rescue themselves. It is the darkness of guilt we cannot erase, grief we cannot undo, and fear about what lies ahead.
Advent begins by telling the truth about that darkness. It does not ask us to pretend that everything is fine. It does not say that hope means looking on the bright side or convincing ourselves that life will turn out as we wish. Biblical hope begins with the hard truth that we need saving—and then announces the greater truth that God has acted to save.
Isaiah 9 was first spoken to people who knew darkness firsthand. The kingdom of Judah was threatened by powerful enemies. Fear and instability had spread through the land. The previous chapters of Isaiah describe a people turning from the Lord and suffering the consequences of their rebellion. In Isaiah 8:22, the picture is bleak: distress, darkness, and gloom. But then, in Isaiah 9, the prophet announces that darkness will not have the final word.
Listen to the opening promise from Isaiah 9:2 (ESV): “The people who walked in darkness have seen a great light; those who dwelt in a land of deep darkness, on them has light shone.”
That promise points first to God’s future work among his people. And as the Gospel of Matthew shows us, it finds its fullest fulfillment in Jesus Christ (Matthew 4:12–16). The promised light has come into the world. The child has been born. The Son has been given.
As we begin Advent, we will see four reasons this passage gives us hope: God’s light reaches people in darkness; God breaks the power of oppression; God gives us the promised King; and God’s King will reign forever.
1. God’s light reaches people in darkness
Isaiah begins, not with an instruction to the people, but with an announcement about what God will do: “The people who walked in darkness have seen a great light.”
Notice who receives the light. It is not a group of people who have climbed their way out of darkness. It is not those who have already found the road back to God. They are people “who walked in darkness,” people who “dwelt in a land of deep darkness.” The light comes to them.
That is the shape of grace. God does not wait until we have made ourselves worthy of rescue. He comes to us in our need.
Isaiah’s words would have brought to mind a particular region: the territories of Zebulun and Naphtali, in the north of Israel. These areas had experienced invasion and humiliation. They were among the first to suffer when powerful enemies came against the land. The darkness was not just a private feeling; it was connected to real danger, grief, and national distress.
But Isaiah announces a reversal. The places associated with shame and gloom will be among the first to see God’s light. God does not overlook the people who seem far away or forgotten. He brings hope to the very places where darkness has settled in.
Matthew tells us that Jesus began his public ministry in this region. He connects Jesus’ work with Isaiah’s promise: the people dwelling in darkness have seen a great light (Matthew 4:12–16). Jesus is not merely a teacher who points toward the light. He is the promised light coming into the darkness.
And what does that light do? It shows us God. It exposes the truth about our sin, not to leave us in shame, but to lead us to the Savior. It reveals the way back to the Father. It brings life where there was death and hope where there was despair.
We should be honest about what the Bible means by darkness. It is more than a difficult week or a season of sadness. Darkness includes the evil we see around us, but also the sin within us. We are not only victims of a broken world; we also contribute to its brokenness. We have all turned away from God in our own ways. We have trusted ourselves, loved what is wrong, and failed to love God and our neighbors as we should.
That is why we need more than a little encouragement. We need forgiveness. We need reconciliation with God. We need someone who can lead us out of darkness and give us new life. Jesus came to do precisely that.
This does not mean that everyone who belongs to Jesus will feel cheerful every day. The Bible does not promise that Christians will never grieve, struggle with depression, experience fear, or face suffering. It does promise that sorrow and struggle do not mean God has abandoned his people. The light has come, and the darkness cannot overcome him.
Think of a family walking together at night with one lantern. The lantern does not make the whole landscape bright. It does not remove every obstacle from the path. But it does give enough light to take the next step, and it reminds the family that they are not walking alone.
The hope Jesus gives can be like that. He may not show us everything that will happen next. He does not always explain why suffering has come. But he gives us himself, his word, and his promise to remain with his people. He is enough light for the next step.
So where do you need the light of Christ today? Perhaps you are carrying guilt from something you have done. Do not hide it from God or try to compensate for it by becoming impressive. Bring it to Jesus, who died for sinners and rose again. Perhaps you feel that no one sees your grief. The Lord sees you, and he is not ashamed to draw near to the brokenhearted. Perhaps a child here feels afraid about something that is happening at school or at home. You can ask a trusted adult to pray with you and remind you that Jesus is with his people.
And if you have not trusted Christ, hear the invitation in this passage: you do not have to make yourself bright before you come to him. Come to Jesus in the darkness. Trust him to forgive you and bring you into the light.
Advent hope is not the belief that we can find our way out by ourselves. It is the good news that God has come to us in Jesus.
2. God breaks the power of oppression
Isaiah continues by describing the joy that will follow God’s deliverance. In Isaiah 9:3 (ESV), he says, “You have multiplied the nation; you have increased its joy.” The people rejoice like workers celebrating a harvest, or like those dividing the spoil after a victory.
These are ordinary pictures of great happiness. A harvest means the long work has borne fruit. A victory means the threat has been turned back. Isaiah is saying that God’s rescue will bring joy that is deep and shared.
Then the prophet explains what God will break: “the yoke of his burden,” “the staff for his shoulder,” and “the rod of his oppressor” (Isaiah 9:4, ESV). These are images of heavy labor and cruel rule. The people are pictured as bent under a weight they cannot lift. But God will break the yoke.
Isaiah says this deliverance will be “as on the day of Midian.” That refers to the story in Judges 7, when God delivered Israel through Gideon. The army was reduced to a small number so that Israel could not boast in its own strength. The rescue made clear that salvation came from the Lord.
That matters because God’s people could not save themselves from their enemies. Their hope did not rest in having the most powerful army, the most skilled leaders, or the strongest plans. Their hope rested in God’s power and faithfulness.
Isaiah adds another vivid picture in verse 5: “For every boot of the tramping warrior in battle tumult and every garment rolled in blood will be burned as fuel for the fire” (ESV). The equipment of war will no longer be needed. The bloodstained garments will be burned. God’s promised future is not a permanent cycle of violence. It is peace.
We should not miss how large this promise is. The passage does not offer a small improvement in the people’s circumstances. It looks toward the end of oppression and the end of war. God’s rescue brings a peace that human beings cannot finally establish by their own strength.
The world still gives us plenty of reasons to long for that peace. Some people live under the threat of violence. Some endure injustice or abuse. Some carry the lasting effects of someone else’s sin against them. Others feel bound by their own destructive habits: anger that keeps returning, lies that have become a way of life, or an addiction that seems to have gained power over them.
Isaiah’s promise does not mean every burden disappears as soon as we believe. Christians still face sin and suffering. We still need help, protection, wise counsel, and, at times, the support of medical and mental-health professionals. The church should not tell people to call evil good or to endure abuse in silence. Seeking safety and help is not a lack of faith.
But Jesus has begun the great work of deliverance. Through his death and resurrection, he has defeated the power of sin and death. Those who trust him are forgiven and welcomed into God’s family. They are no longer under sin’s rightful condemnation. And one day Christ will return and put an end to every evil that harms his people.
That promise shapes how Christians live now. We do not wait for perfect peace by becoming passive in the face of suffering. We work for what is good, protect the vulnerable, tell the truth, forgive as we have been forgiven, and seek peace where peace is possible. We do those things not because we can bring God’s kingdom by our own strength, but because we belong to the King whose kingdom is coming.
A child might understand this through the image of a heavy backpack. If you are carrying something too heavy to lift, a kind person does not simply tell you to stop feeling tired. They come alongside you and help carry the weight. Jesus does more than offer encouraging words to people who are burdened by sin and shame. He bears the judgment we deserve. He carries our guilt to the cross.
That is why Christian hope is not shallow optimism. The cross shows that God takes sin seriously. The resurrection shows that sin and death do not win. Jesus did not rescue us by pretending our evil was harmless. He gave himself for us, and God raised him from the dead.
If you are carrying a burden today, you do not have to carry it alone. Bring it to the Lord. Bring it, too, to a mature Christian who can listen and help you take wise next steps. If your burden is guilt, confess your sin and trust the mercy of Christ. If it is suffering, let other believers walk with you. If someone has harmed you, seek safety and support. And if the burden is a particular sin that has become a pattern, ask for help rather than fighting alone in secret.
The final answer to all oppression will come when Jesus reigns in fullness. Until then, his people can live with courage and compassion because the King has come and will come again.
3. God gives us the promised King
Now Isaiah tells us how God will bring this rescue. The answer is one of the most familiar promises of the Advent season. Isaiah 9:6 (ESV) says:
“For 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.”
The hope of God’s people is tied to a person. God’s answer is not merely a new policy, a stronger army, or a better mood. God gives a King.
The first words are wonderfully personal: “To us a child is born, to us a son is given.” The child is born into the world. The Son is given by God. The promised ruler is truly human and yet comes as God’s gift. Christians see this promise fulfilled in Jesus Christ: the eternal Son of God took on human nature and was born into our world. He entered history not as a distant idea, but as a real child, born to a real mother, in a world marked by fear, hardship, and sin.
The names Isaiah gives this King show what sort of ruler he is.
He is called “Wonderful Counselor.” This is not just someone who offers helpful suggestions. He is the King whose wisdom is beyond our wisdom. He sees what we cannot see and knows the way of true life. The counsel of Jesus is not always the counsel we would choose. He tells us to repent, to forgive, to trust God, to love our enemies, and to take up our cross. Yet his wisdom is good, because it comes from the goodness of God.
He is “Mighty God.” Isaiah’s promised King does not merely give advice from a distance. He has power to save. Jesus has authority over sickness, storms, demons, sin, and death. He is not a weak ruler who feels sorry for his people but cannot help them. He is able to do what we cannot do: rescue sinners and bring them to God.
He is “Everlasting Father.” This does not mean the Son is the same person as God the Father. Scripture teaches that the Father and the Son are distinct persons, and that the Son is fully God. Here, Isaiah is describing the King’s fatherlike care for his people: his protection, compassion, and faithful rule. Unlike earthly leaders who may leave, fail, or die, this King’s care will never run out.
He is “Prince of Peace.” His rule is not built on selfishness or cruelty. He brings peace with God through the forgiveness of sins, and one day he will bring complete peace to all creation. He is the King who reconciles enemies to God and makes a people who learn to live in peace with one another.
For many of us, the word “king” may feel distant. We think of history books, crowns, and palaces. But everyone lives under some kind of authority. We may act as if we are our own rulers, deciding that our desires are the highest law. Or we may let other things rule us: the need for approval, success, money, comfort, or control.
Isaiah’s passage asks us to consider: who is on the throne of your life? Jesus is not one helpful adviser among many, to be consulted only when we want a religious opinion. He is the King. His word speaks to all of life.
Yet his authority is not a reason to run away from him. Consider the difference between a ruler who uses power for himself and a king who gives himself for his people. Jesus does not demand that his people carry the burden of earning his acceptance. He laid down his life for them. The cross shows us that the King’s power is joined to his sacrificial love.
We are saved by grace alone, through faith alone, in Christ alone. We do not earn a place in his kingdom by good deeds, religious effort, or family background. We receive the gift of salvation by trusting in Jesus, who died for our sins and rose again. And those who trust him are then called to follow him as their King.
That call is for every age. Children can learn to trust and obey Jesus in ordinary moments: telling the truth, asking forgiveness, and showing kindness. Teenagers can follow him when friends pressure them to go along with what is wrong. Adults can trust him in their work, relationships, decisions, and use of money. Older believers can continue to encourage the church and bear witness to the faithfulness of Christ. None of us has outgrown our need for Jesus.
Following Jesus will not always be easy. Sometimes his word will correct us. Sometimes obedience will cost us something. But there is no safer King, because there is no King who loves his people more. He is the Wonderful Counselor who knows the way, the Mighty God who can save, the faithful King who cares for us, and the Prince of Peace who reconciles us to God.
4. God’s King will reign forever
Isaiah 9:7 tells us what will happen under this King’s rule:
“Of the increase of his government and of peace
there will be no end,
on the throne of David and over his kingdom,
to establish it and to uphold it
with justice and with righteousness
from this time forth and forevermore.
The zeal of the LORD of hosts will do this” (ESV).
The promised King will reign on David’s throne. God had promised David that his royal line would have a lasting future (2 Samuel 7:12–16). Isaiah now looks ahead to a ruler whose kingdom will not collapse. The government will keep increasing, and peace will have no end.
That promise reaches further than any ordinary political victory. The kings of this world come and go. Their plans are limited. Even the best leaders cannot remove every injustice or keep every promise. But Isaiah describes a King whose rule is upheld “with justice and with righteousness.” He will not be corrupt, careless, or cruel. He will not use power to protect himself at the expense of his people. His kingdom will be established and upheld forever.
The final sentence tells us why this hope is certain: “The zeal of the LORD of hosts will do this.” God himself is committed to bringing about what he has promised. The future does not depend on our ability to make everything right. It depends on the faithfulness and power of the Lord.
This matters because the Christian life is lived between the first coming of Jesus and his return. Jesus has come, and his light has shone in the darkness. He has died and risen. He has begun to gather a people for his kingdom. But we still wait for the day when every wrong is made right and peace has no end.
That means Christians are people who can grieve and hope at the same time. We do not have to deny pain in order to trust God. We can lament what is wrong, pray for help, and work for good while believing that evil will not have the last word.
Imagine a child waiting for a loved one to come home. The house may be quiet, and the wait may feel long. But the child has been given a promise and knows whom they are waiting for. Christian hope is not merely a vague wish that things might improve. It rests on the promise and character of God—and on the returning King who has already shown us his love.
Waiting can be hard. We may wonder why suffering continues, why prayers seem unanswered, or why the world is still full of conflict. Isaiah does not answer every question about the timing of God’s plan. But he gives us something firm to hold on to: God has acted, God is faithful, and God will finish what he has begun.
So we do not put our ultimate hope in a particular election, a strong economy, a successful career, a healthy family, or a pain-free life. Those things can be good gifts, but none of them can bear the weight of our deepest hope. Our hope belongs to Jesus. His kingdom will not end, his justice will not fail, and his peace will not run out.
This hope also changes the way we treat people now. If our King is righteous, we should care about truth and justice. If he is the Prince of Peace, we should seek peace in our homes and relationships. If his kingdom welcomes people by grace, we should not look down on those who need mercy. We are not building a perfect world by ourselves; we are living as citizens of the coming kingdom.
And when the darkness around us feels especially thick, we can remember that waiting is not the same as being abandoned. The Lord who promised to bring the light is the Lord who keeps his promises. The zeal of the Lord will do this.
Conclusion
Isaiah spoke to people who knew what it was like to live under threat and in gloom. He did not tell them to pretend the darkness was imaginary. He announced that God would bring light. He promised that the burden would be broken, that the people would rejoice, and that a child would be born—a Son given—whose kingdom would never end.
Matthew tells us that the promised light has come in Jesus Christ. Jesus entered our darkness. He lived without sin, gave his life on the cross for sinners, and rose from the dead. He is the King who forgives and frees his people. And he will return to complete the work he began.
That is the hope of Advent. Not that we have no trouble. Not that we can fix everything. Not that tomorrow will necessarily be easier than today. Our hope is that Jesus has come, Jesus is with his people, and Jesus will come again.
So if you are grieving, you can bring your grief to him. If you are burdened by guilt, you can receive his forgiveness. If you are afraid, you can take the next step with him. If you have never trusted him, you can come to him today.
The people who walked in darkness have seen a great light. The light is Jesus Christ. And the darkness will not have the final word.
Call to response
I want to invite each of us to respond to this promise.
If you have never trusted Jesus, do not wait until you feel worthy or have sorted everything out. Turn to him now. Admit your need, turn from sin, and trust that Jesus died and rose again to save all who come to him. You can speak to God in your own words, and you can speak with me or another Christian after the service. We would be glad to pray with you.
If you are already following Jesus, ask where you need to trust his light today. Is there sin you need to confess? A burden you need to share? Someone you need to forgive, or a person you need to protect and help? Take a next step in the light of Christ, trusting that he is a better King than any other thing that might try to rule your life.
And as a church, let us be a people who do not hide the darkness or surrender to it. Let us point one another to Jesus, the Light who has come and the King who is coming again.
Closing prayer
Father, thank you for sending your Son into our darkness. Thank you that Jesus is the Light of the world, the Savior of sinners, and the King whose kingdom will never end. Forgive us for trusting ourselves and other things more than we trust him. Give hope to those who are grieving, courage to those who are afraid, help to those who are burdened, and faith to those who are seeking you. Teach us to walk in the light of Christ and to live as people of his coming kingdom. We ask this in Jesus’ name. Amen.
