Preparing for the Peace-Bringer

Introduction

Greetings. As we continue in this Advent season, we often hear about "peace." We may think of peace as a holiday wish: Peace on earth to men of good will.

Peace be with you.

We may think of it as a calm, goodwill, quiet dinners, getting along with family. But Scripture speaks of peace as something far deeper - something that transforms the heart and changes how we live.

It doesn't matter what is going on. There might be chaos around us, but we could still have that inner peace.

In Matthew 3, we encounter John the Baptist preaching. He was not preaching about calm political compromise. He was not preaching about peaceful social order. He was preaching about repentance.

And the reason for his call to repentance, is because the "kingdom of heaven" was near. And he said that at the center of that kingdom was not John the Baptist himself, but Jesus Christ - the true Peace-Bringer.

Specific Purpose Statement: Today we will walk carefully, verse by verse, through Matthew 3:1-12.

(Prayer: Father, Son, Holy Spirit, we pray that as we go through today's text, please lead us to see what true peace looks like, how it begins, and how we can participate in it and how we can share it to others. In Jesus' name. Amen)

Expository Walkthrough

Verses 1-2

1 In those days John the Baptist came, preaching in the wilderness of Judea 2 and saying, "Repent, for the kingdom of heaven has come near."

"Repent, for the kingdom of heaven has come near."

John appears "in those days" - in a world that looked ordinary, but a world that was spiritually hungry. His opening words: "Repent, for the kingdom of heaven has come near."

Repent - was from the Greek word (metanoia): This word is more than remorse. It is a call to a reorientation of mind and heart - in a radical way. It means to turn away from old ways of thinking, and to turn toward God's purposes.

The kingdom is near: Not distant, not vague - but present, breaking into history. God is acting, drawing people to Himself.

Application: Many in our world today seek peace. Peace, instead of anxiety, conflict, emptiness. But true peace begins with a changed mind and heart. As believers, we must regularly examine ourselves: Have we become complacent? Are we living as if God's kingdom is "far off"? Or are we alert to his presence and willing to turn toward him?

Illustration: Imagine a ship drifting slowly toward the rocks because its rudder is ignored. Repentance is like turning the wheel - preventing disaster and setting the ship on a safe course.

Verse 3: John fulfilling prophecy

3 This is he who was spoken of through the prophet Isaiah: "A voice of one calling in the wilderness, `Prepare the way for the Lord, make straight paths for him.'"

John is not an accidental preacher - he fulfills prophecy. The return from exile, the hard service finished, sins paid for (which is the context of Isaiah 40) - God is acting to deliver, restore, bring comfort and peace.

John is God's appointed messenger: God's plan is unfolding; the time of waiting is ending.

Application (GCI theology connection): As people who trust in the triune God - Father, Son, Spirit - we affirm that God in Christ has reconciled humanity to himself. Through Jesus, God is drawing all people into the life of the Trinity. John's ministry prefigures that gracious work of redemption. Thus, our hope does not rest in ourselves, but in the God who acts to restore, renew, and reconcile. The peace of God is an act of divine love reaching into our broken world.

Verses 4-6: John's character and the people's response

4 John's clothes were made of camel's hair, and he had a leather belt around his waist. His food was locusts and wild honey. 5 People went out to him from Jerusalem and all Judea and the whole region of the Jordan. 6 Confessing their sins, they were baptized by him in the Jordan River.

John's manner of life - simple, austere - speaks truth: he is not seeking worldly comfort, popularity, or power. His lifestyle underlines the message: leave the old world behind; prepare for the kingdom to come.

The people responded not because of a spectacle - but because of sincerity. Their baptism was a visible sign that they were turning from sin, trusting God, and preparing themselves for something greater.

Application to the church today: Sometimes believers adopt a "comfortable Christianity" - neat clothes, nice buildings, polished programs - yet we forget that the gospel calls us to authentic humility, honesty, and simplicity.

As a congregation belonging to GCI, we believe our union with Christ is not a superficial membership, but a living reality. Our life together is grounded in humility, grace, and authentic community. We, like those early people in the Jordan, are invited to confess, repent, and publicly identify with Christ - not as a ritual to earn favor, but as a humble response to God's grace.

Verses 7-10: Confronting self-righteousness - "You brood of vipers!"

7 But when he saw many of the Pharisees and Sadducees coming to where he was baptizing, he said to them: "You brood of vipers! Who warned you to flee from the coming wrath? 8 Produce fruit in keeping with repentance. 9 And do not think you can say to yourselves, `We have Abraham as our father.' I tell you that out of these stones God can raise up children for Abraham. 10 The ax is already at the root of the trees, and every tree that does not produce good fruit will be cut down and thrown into the fire.

John's words turn sharp: He addresses "crowds" - including religious leaders - with harsh imagery. He warns them: don't rely on ancestry or external identity (They were saying: "We have Abraham as our father"). Produce fruit in keeping with repentance.

The message: True repentance isn't about lineage, ritual, or privilege. It demands a changed heart that bears fruit - visible, life-changing fruit.

The "ax at the root" - the judgment that comes if people persist in old ways - shows that partial or surface-level religion won't suffice.

Application to believers: Even in Christian communities, there can be a temptation to trust in tradition, good reputation, or external forms. But such trust can become a barrier to real transformation.

If we claim to be Christians yet live as the world does - holding grudges, indulging in selfishness, ignoring the poor - we miss the point. The gospel calls for a revolution of the heart, not just maintenance of appearances.

GCI's theology underscores that we are saved by Christ alone. Yet that salvation invites a transformed life - not as a means to earn favor, but as the natural outworking of God's grace.

Verses 11-12: He will baptize you with the Spirit and fire

11 "I baptize you with water for repentance. But after me comes one who is more powerful than I, whose sandals I am not worthy to carry. He will baptize you with the Holy Spirit and fire. 12 His winnowing fork is in his hand, and he will clear his threshing floor, gathering his wheat into the barn and burning up the chaff with unquenchable fire."

John concludes: He baptizes with water, but after him comes One greater - Jesus of Nazareth - who will baptize with the Holy Spirit and with fire.

The water baptism that John offered was preparatory: a symbol, a confession, a willingness to turn.

Jesus' baptism is transformative: the Spirit cleanses, renews, empowers; He makes his people alive in a new way.

Theological significance (GCI): According to the beliefs of Grace Communion International, at the moment of salvation the Holy Spirit regenerates us, indwells believers, and baptizes them into the one body - the church. Baptism in water is not a magical ritual that produces regeneration by itself - but is a meaningful sign and seal of God's grace, pointing us to Christ's death and resurrection, and our union with him. Therefore: The ultimate peace - the deep peace that overcomes fear, guilt, alienation - comes not by our efforts, but by Jesus, through the Holy Spirit.

Application: As believers, we can rest in the assurance that our identity is secure in Christ. We don't live by trying to prove ourselves - but by living in the grace and power of the Holy Spirit, displaying the fruit of new life.

Contemporary Church Application & Invitation

1. Recognize the world's need for real peace

We live in a time of anxiety: social division, economic stress, moral confusion, spiritual emptiness. People crave peace, yet what they often find is superficial - distractions, temporary fixes, the next "thing." As a church, we can offer something different - real peace.

But first, like the crowds by the Jordan, many must hear the call: "Repent." - not as condemnation, but as invitation to new life.

2. Offer the gospel - the peace of Christ by the Spirit

Because of what Christ has done, we can say with confidence: we don't bring a checklist; we bring grace. We don't offer performance, we offer forgiveness. We don't demand perfection; we offer the transforming power of the Holy Spirit.

This is true to GCI's vision of God as the triune God in loving communion - Father, Son, and Spirit - inviting us into that communion, and inviting us to live as one body, united in Christ.

3. Live as people of peace - bearing fruit

Our baptism (or our commitment to Christ) isn't the end of the story. It's the beginning. The Spirit continues to work in us. We grow in love, joy, peace, kindness, righteousness. As a congregation, we should be known not for "religious people," but for "people of peace." In our homes, workplaces, community - we carry the peace of God in our hearts and show it in our actions.

4. Invite others to the gospel of peace

John didn't keep the message to himself. He "pointed away" from himself toward the One who was coming. Likewise, we as a church must live as ambassadors of Christ - inviting others, modeling repentance and grace, offering the hope of transformation.

Conclusion & Invitation

Matthew 3 calls us back to the beginning of the gospel story. It calls us to prepare - to repent, to turn, to live in awareness that God's kingdom is near.

It calls us not to rely on our comfort, our status, or our religiosity - but to rely on Christ, who baptizes with the Holy Spirit, who cleanses, renews, and empowers.

As members (or friends) of a church shaped by the theology of Grace Communion International, we believe in a gracious triune God who invites us into union with himself - and who transforms our lives by his Spirit. If you have never responded to that call - to repent, to trust, to receive Christ - I invite you now. If you have responded, I encourage you: examine your life. Are you bearing fruit? Are you living as a person of peace? Are you pointing others to the true Peace-Bringer?

Let us pray that God by his Spirit will make this more than a sermon. Let it become our life, our witness, our peace, our hope. Amen.
