Acts 2:14-42

Sermon on Acts 2:14–47

Title: When the Spirit Speaks Text: Acts 2:14–47 Theme: The Spirit-empowered Church boldly proclaims Christ, produces conviction, and bears fruit in transformed community. Big Idea (repeatable phrase): When the Spirit speaks through the Church, lives are changed forever.

I. The Bold Proclamation of the Gospel (vv. 14–36)

Peter, once timid and afraid (denying Jesus three times), now stands and proclaims with power.

Peter explains Pentecost through Joel 2—this is not drunkenness but the outpouring of God’s Spirit. He moves to proclaim the life, death, resurrection, and exaltation of Jesus (vv. 22–36). The Spirit’s role is to make Christ known.

Illustration: Think of a megaphone. A megaphone doesn’t create a new message; it amplifies what’s already spoken. The Holy Spirit is the “megaphone” of Jesus—He doesn’t draw attention to Himself but magnifies Christ.

Quote: Charles Spurgeon said, “Without the Spirit of God, we can do nothing. We are as ships without wind, branches without sap, and like coals without fire—we are useless.”

Application: We, too, are called to open our mouths with boldness. The Spirit empowers ordinary people to testify about an extraordinary Savior.

Key phrase: When the Spirit speaks, Christ is proclaimed.

II. The Piercing Conviction of the Gospel (vv. 37–41)

Exegesis: The people are “cut to the heart.” That phrase (κατενύγησαν τὴν καρδίαν) means stabbed deeply, pierced within. Peter calls them to repentance, baptism, and faith in Christ.

Illustration: Imagine a surgeon’s scalpel. It cuts not to destroy but to heal. The Spirit’s conviction is not condemnation without hope—it is the wound that leads to healing.

Quote: John Stott: “We must never bypass the cross. The Spirit comes to us as a spirit of conviction before He comes as a spirit of comfort.”

Application: True revival isn’t just emotional excitement; it is deep repentance. The same Spirit who comforts is also the One who convicts.

Key phrase: When the Spirit speaks, hearts are pierced and transformed.

III. The Beautiful Community of the Gospel (vv. 42–47)

Exegesis: The Spirit’s work produces a new kind of people: devoted to the apostles’ teaching, fellowship (koinonia), breaking of bread, and prayer. They shared possessions, cared for the needy, and worshiped with glad hearts. This is the Spirit-formed church.

Illustration: A coal alone grows cold, but coals together burn bright. The Spirit gathers believers into a fellowship where their fire for Christ is sustained.

Quote: Dietrich Bonhoeffer wrote, “The Church is not a religious community of worshipers of Christ but Christ Himself who has taken form among people.”

Application: Christianity is not just “me and Jesus.” It’s “us in Christ.” The Spirit does not only save individuals; He creates a community that reflects God’s kingdom on earth.

Key phrase: When the Spirit speaks, the Church becomes a living witness to Christ.

IV. The Ongoing Fruit of the Gospel (v. 47)

Exegesis: The Lord added daily to their number those who were being saved. The Spirit’s work doesn’t end with one sermon; it continues through a faithful community.

Illustration: A healthy tree doesn’t force itself to bear fruit—it naturally produces because of its roots and life within. The Spirit-filled Church is that kind of tree.

Quote: A.W. Tozer said, “If the Holy Spirit was withdrawn from the New Testament church, 95 percent of what they did would stop. But if the Holy Spirit was withdrawn from the church today, 95 percent of what we do would go on, and nobody would know the difference.”

Application: Our mission is ongoing. When the Spirit works through us, people will continually be drawn to Christ.

Key phrase: When the Spirit speaks, the world sees Jesus and people are saved.

Conclusion

Acts 2:14–47 shows us what happens when the Spirit speaks:

Christ is proclaimed.

Hearts are pierced.

The Church is formed.

The mission advances.

Closing Illustration: The great revivalist D.L. Moody once said, “The world has yet to see what God can do with a man fully consecrated to Him.” Imagine what God can do with a church fully surrendered to the Spirit.

Final Call: Let us be that church—bold in proclamation, humble in repentance, devoted in fellowship, and faithful in mission.

Really focus on the church devoting to the teaching of the Word and to one another and the impact it had and how it applies to us today. Write a charge at the end

Perfect — let’s zoom in on Acts 2:42–47, with special attention to the church’s devotion to the Word and one another. I’ll structure the sermon around that theme and close with a pastoral charge.

Sermon on Acts 2:42–47

Title: The Devoted Church Text: Acts 2:42–47 Theme: The Spirit-filled church is marked by devotion to God’s Word and one another, and through that devotion, the world is changed. Big Idea: When the church devotes itself to the Word and to one another, God works in powerful ways.

I. A Devotion to the Word (v. 42a)

“They devoted themselves to the apostles’ teaching…”

Exegesis: The word devoted (προσκαρτεροῦντες) implies steadfast perseverance and loyalty. The early church didn’t treat the Word as optional—this was their lifeline. They clung to the apostles’ teaching because it revealed Christ.

Illustration: Imagine a newborn baby clinging to its mother for nourishment. Peter later writes, “Like newborn infants, long for the pure spiritual milk, that by it you may grow up into salvation” (1 Pet. 2:2). Just as a baby cannot survive without milk, the church cannot survive without the Word.

Quote: John Wesley once said, “I want to know one thing — the way to heaven… God himself has condescended to teach the way: for this very end he came from heaven. He hath written it down in a book. O give me that book!”

Application: In a world drowning in voices, we must be a people shaped not by news cycles, social media, or cultural trends, but by the Word of God. When the church devotes itself to Scripture, it doesn’t just gain information—it receives transformation.

Key phrase: Devotion to the Word makes a people who look like Jesus.

II. A Devotion to One Another (vv. 42b–47)

“…and to the fellowship, to the breaking of bread and the prayers… they had all things in common… they were together.”

Exegesis: Koinonia (fellowship) is more than coffee and donuts—it is sacrificial sharing of life. They ate together, prayed together, met needs together. Their devotion to one another was so radical that Luke says “there was not a needy person among them” (Acts 4:34).

Illustration: A single coal taken out of the fire quickly grows cold, but when coals are together, they keep each other hot. So too with believers: isolated faith grows cold, but fellowship fans the flame.

Quote: Dietrich Bonhoeffer: “The physical presence of other Christians is a source of incomparable joy and strength to the believer.”

Application: In an individualistic age, true devotion to one another is countercultural. It means bearing burdens (Gal. 6:2), confessing sins (James 5:16), and rejoicing with one another (Rom. 12:15). When the world sees a community of sacrificial love, it sees a glimpse of God’s kingdom.

Key phrase: Devotion to one another makes a people who shine with Jesus.

III. The Impact of Their Devotion (vv. 43–47)

Exegesis: Their devotion produced awe, generosity, joy, favor with outsiders, and daily conversions. Notice the pattern: Word + fellowship → transformed community → watching world is drawn to Christ.

Illustration: Think of a lighthouse. Its purpose is not to draw attention to itself but to shine light to guide ships safely home. The early church, by their devotion to Word and one another, became a lighthouse in a dark world.

Quote: Tertullian (early church father) reported pagans saying of Christians: “See how they love one another!”That love, rooted in truth, was evangelism itself.

Application: If we want to see renewal today, it won’t come through slick programs or polished strategies alone. It will come when the people of God are deeply devoted to God’s Word and radically committed to one another.

Key phrase: Devotion fuels transformation, and transformation draws the world to Christ.

Charge to the Church

Church, Acts 2 is not just a history lesson—it is a blueprint. The Spirit-filled church was marked by devotion. They were not casual consumers; they were committed disciples.

So I charge you today:

Be devoted to the Word. Don’t let the Bible sit closed six days a week. Read it, hear it, meditate on it, obey it. Let it shape your mind, your speech, your decisions, your family, your church.

Be devoted to one another. Don’t settle for surface-level relationships. Open your homes, share meals, pray for each other, carry burdens, rejoice and weep together. Refuse to let anyone walk alone.

Be devoted with perseverance. The world is watching. And when the church truly devotes itself to the Word and to one another, God moves in power.

Closing Line (repeat): When the church devotes itself to the Word and to one another, the world cannot help but see Jesus.

Would you like me to craft this into a revival-style sermon (with more urgency, altar call emphasis), or keep it in a teaching/expository tone for a Sunday morning congregation?

Great question. The short answer is no — “devoted” and “covenant” are not the same in Greek, though both carry strong ideas of commitment. Let me break it down for you.

1. “Devoted” in Acts 2:42

The Greek word is προσκαρτερέω (proskartereō).

It means to continue steadfastly, to persist, to adhere closely, to be loyal to, to busy oneself with.

In Acts 2:42 it describes the church’s ongoing, consistent practice of being committed to the apostles’ teaching, fellowship, breaking of bread, and prayer.

It’s about habitual perseverance and loyalty.

2. “Covenant” in Greek

The main word is διαθήκη (diathēkē).

It means covenant, testament, a binding agreement or promise initiated by God.

In the Bible, covenant is not just devotion or loyalty — it’s a formal, relational bond established by God (e.g., with Abraham, Israel, and ultimately fulfilled in Christ).

It’s legal, relational, and theological.

3. The Difference

Devotion (προσκαρτερέω): describes the church’s response — their steadfast commitment.

Covenant (διαθήκη): describes God’s initiative — His binding promise and relationship with His people.

Put simply: Covenant is the framework God establishes. Devotion is how His people live inside that covenant.

4. How They Connect in Acts 2

You could say:

God had made a new covenant through Christ’s blood (Luke 22:20).

Now the church, empowered by the Spirit, expressed devotion by living faithfully in that covenant relationship — through Word, fellowship, worship, and prayer.

⚡So to answer your question: No, “devoted” and “covenant” are not the same word or concept in Greek. But they are connected — covenant is the ground, and devotion is the response.

Would you like me to help you weave that distinction into your sermon, so you can explain how the early church lived out covenant loyalty through their devotion?
