The Spirit Builds Community

Introduction

Text Introduction

Please open your Bibles to Acts 2:40–47. We are picking up at the end of Peter’s sermon on Pentecost Sunday and then stepping into the first summary statement in Acts, which gives us a big-picture view of what life in the early church looked like and how this Spirit-formed community began to grow.

Will you read along in Acts 2:40?

Read Acts 2:40-47

Acts 2:40–47 NKJV

40 And with many other words he testified and exhorted them, saying, “Be saved from this perverse generation.” 41 Then those who gladly received his word were baptized; and that day about three thousand souls were added to them. 42 And they continued steadfastly in the apostles’ doctrine and fellowship, in the breaking of bread, and in prayers. 43 Then fear came upon every soul, and many wonders and signs were done through the apostles. 44 Now all who believed were together, and had all things in common, 45 and sold their possessions and goods, and divided them among all, as anyone had need. 46 So continuing daily with one accord in the temple, and breaking bread from house to house, they ate their food with gladness and simplicity of heart, 47 praising God and having favor with all the people. And the Lord added to the church daily those who were being saved.

Prayer

Heavenly Father, we ask that You would move in our midst by Your Spirit today as You did on Pentecost. Help us not only to understand Your Word, but also to respond to it. Shape us as Your people, draw us together in unity, and form us into a faithful, living church that reflects Christ. We ask this in Jesus’ name, amen.

Introduction

What are you looking for in a church?

It’s a natural question, and a good one to ask, because we should all want to belong to a healthy, thriving church. But sometimes when we focus on what we want from the church, we forget to ask an even more important question: what does Christ want from His church?

Healthy churches are not built by spectators. They are built as believers are joined together in Christ and actively participate in the life of the church.

In Acts 2, we see a snapshot of the first church—the first gathering of believers after Pentecost. Some of what we see is unique to that time and place. But as we read through the rest of Acts and the New Testament letters to churches in a wide variety of settings, we find enduring principles that describe how the Spirit of God moves believers to engage and grow in the life of the local church.

This morning, I want to focus on four important ways believers participated in the life of the early church, and I want to encourage you to listen with this question in mind: what next step is the Holy Spirit leading me to take today?

1. Joining the Church Community

The first step is the same for everyone: joining the local church community. This isn’t a goal in itself, but the natural result of salvation.

In his sermon, Peter called the crowds to be saved. And look at what happens in verse 41:

First, they received his word.

This means they believed in Jesus for salvation. They became Christians. They were made new. Their sins were forgiven, and they were adopted as children of God.

Luke points out that they “gladly” received Peter’s word because they were rejoicing in the good news. Salvation may involve tears, but they are tears of joy—because we are forgiven and made right with God.

If we think too individualistically, we might assume this is the end of the story: I’m saved, so what more is there? But salvation in Scripture is far more than private experience.

Second, they were baptized.

Here in Acts, and throughout the Bible, baptism is an outward confession of an inward reality and a visible entrance into the life of the church. It is a public declaration that our sins have been washed away through the blood of Jesus Christ—that we have died to sin and been raised to new life in Him.

God’s design is not that believers would quietly keep their faith to themselves when they receive good news. His design is that we would witness to and share the transformation we have experienced. Baptism is one of God’s appointed ways to do that.

But even this is not the end.

Third, souls were added to them.

Do you see the significance of this? Those who believed and were baptized were added to a community of believers. They were added to the church.

This is what church membership is ultimately about. This is what joining the church is about. Because when Christ saves us, He brings us into His body and His family.

God is not just saving individuals from sin. Titus 2:14 tells us why God is redeeming us from every lawless deed. Why? Because He is purifying for Himself His own special people.

Being a believer means being added to the church community, the people of God.

Application: Your Next Step

For some today, you may already be filling the Holy Spirit guiding your next step:

Maybe that next step is faith in Christ—receiving His Word and being saved.

For others, the next step is baptism—publicly identifying with Jesus and His church.

For others still, the next step is deeper connection: moving from attending to belonging, from observing to being “added” in a meaningful way to the life of the church by becoming a member of Haven Fellowship Church.

Wherever you are, the question is “Am I being joined to the life of Christ’s people the way Scripture describes?”

2. Growing in the Word of God

And once we are joined to the church, Luke shows us something else that happens in this Spirit-formed community: they grow.

Let's look at the second rhythm of a healthy church—growing in the Word of God.

The Apostles' Doctrine (v. 42)

We see this in verse 42:"And they continued steadfastly in the apostles' doctrine..."

The apostles' doctrine was the teaching of Jesus' followers about the Old Testament and the life, death, resurrection, and teachings of Jesus Christ.

Notice three things about their commitment.

First, They Continued

Luke says they continued in the apostles' doctrine.

Studying God's Word was not something they postponed until they became mature Christians. It was part of their Christian life from the very beginning.

Peter's sermon had led them to faith in Christ. But that sermon was not the end of their spiritual journey—it was the beginning.

These new believers continued learning, growing, and being shaped by God's truth.

The same is true for us. No matter how long we have followed Christ, we never outgrow our need for God's Word.

Second, Steadfastly

Luke doesn't simply say they continued. He says they continued steadfastly.

This was not an occasional interest or an afterthought. They devoted themselves to learning God's truth. They remained committed even when life became busy or difficult.

Healthy Christians are growing Christians, and growing Christians are people who consistently place themselves under the teaching of God's Word.

Third, In the Apostles' Doctrine

The third element is what they continued steadfastly in: the apostles doctrine, or teaching.

Now you might think, "That must have been incredible. They were learning directly from the apostles themselves."

Can you imagine hearing Peter explain the teachings of Jesus? Listening to John describe what he had seen and heard?

But here's the good news: You can! Through the inspiration of the Holy Spirit, the teachings of the apostles have been preserved for us in Scripture.

The New Testament contains the very teachings of the apostles to which the early church devoted itself.

When we open our Bibles, we are not disconnected from the early church. We are learning from the same apostle’s witness that helped shape and strengthen those first believers.

And just as they grew by continuing steadfastly in the apostles' teaching, we grow by continuing steadfastly in God's Word.

Application: Your Next Step

So let me ask you: what is your next step in growing?

Maybe your next step is simply to begin reading God's Word consistently.

Maybe your next step is to become more steadfast in your study of Scripture.

Maybe your next step is to join a Sunday School class where you can grow alongside other believers.

The early church did not merely gather together—they grew together. And God intends the same for us today.

3. Serving the Body of Christ

Not only did these believers grow, they also participated in the life of the church by serving the body of Christ.

One of the things that stands out in this passage is how active these believers were. They were not spectators. They were not consumers. They were not simply attending gatherings and then returning to their own lives.

They were meeting together. They were encouraging one another. They were opening their homes. They were caring for one another's needs. They were participating in the life of the church.

As we continue through Acts, we see this same pattern repeated again and again. The ministry of the church was not carried by a handful of professionals. It was carried by ordinary believers whom God had saved and filled with His Spirit.

Think about who these first Christians were. Most of them had no formal education. They had no seminary training. They had no ministry degrees. They had no church growth manuals.

Yet God used them to change the world.

Why?

Not because of what they possessed, but because of what God had given them.

They had salvation through Jesus Christ.

They had the Holy Spirit dwelling within them.

They had the teaching of God's Word.

And they had fellowship with other believers.

That was more than enough.

In fact, it is still enough.

1 Peter 4:10

Peter later wrote about this his 1 Peter 4:10.

1 Peter 4:10 NKJV

10 As each one has received a gift, minister it to one another, as good stewards of the manifold grace of God.

Notice he says each one.

Every believer has a role to play in the life of the church.

Application: Your Next Step

So let me ask you: what is your next step in serving?

Maybe it is helping with children's ministry.

Maybe it is greeting guests.

Maybe it is serving behind the scenes.

Maybe it is visiting, encouraging, or praying for others.

Maybe it is simply asking, "Where is there a need, and how can I help?"

Healthy churches are not built by a few people doing everything. They are built when every believer uses what God has given them to serve the body of Christ.

4. Giving for God’s Mission

Here in Acts 2, Luke highlights one more way believers responded to God's work in their lives: Giving for God’s mission

Verses 44 and 45 tell us:

Acts 2:44–45 NKJV

44 Now all who believed were together, and had all things in common, 45 and sold their possessions and goods, and divided them among all, as anyone had need.

Why would they do that?

Because they were convinced that God was at work among them.

They had come face-to-face with their need for forgiveness and had experienced the grace of God through Jesus Christ. The kingdom of God was no longer a distant idea. God was moving in their midst.

And when that happened, their priorities changed.

Things that once seemed so important no longer held the same grip on their hearts.

Their focus shifted from What do I have? to How can I help?

From What belongs to me? to How can I use what God has entrusted to me for His purposes?

Now, the specific form of generosity we see here is unique to this situation in Jerusalem. We do not find every church in Acts selling possessions and living in this way.

But while the form may be unique, the principle is not.

Throughout the New Testament, believers are repeatedly called to generosity, sacrificial giving, and care for one another.

The same Holy Spirit who moved these believers to open their hands is still at work in God's people today.

Christian giving is never merely about money.

It is about trust.

It is about worship.

It is about recognizing that everything we have ultimately belongs to God.

It’s about loving others and wanting to meet their needs

Application: Your Next Step

So let me ask you: what is your next step in giving?

Maybe it is giving for the first time.

Maybe it is beginning to give consistently.

Maybe it is growing in generosity.

Whatever the next step may be, remember this: God is not looking for equal gifts from every believer. He is looking for faithful and willing hearts.

The believers in Acts 2 understood that God had given them far more than possessions—He had given them salvation.

And because they had received so much grace, they responded with generosity.

Conclusion

Today we've seen a picture of a thriving church community in Acts 2.

What made this church thrive?

It wasn't a building. It wasn't a budget. It wasn't programs or strategies.

It was a community of believers who responded to the work of the Holy Spirit in their lives by joining, growing, serving, and giving.

And I believe the same Holy Spirit who built that church is still building healthy, thriving church communities today.

He is still saving people. He is still growing disciples. He is still calling believers to serve. He is still moving God's people to generosity.

And He wants to do that here at Haven.

So as we close, I want to bring you back to the question we began with. We often ask what we are looking for in a church. But perhaps the more important question is this:

What is Christ calling me to contribute to His church?

What next step is the Holy Spirit leading you to take today?

Do you need to trust in Christ?

Do you need to be baptized?

Do you need to commit yourself more fully to growing in God's Word?

Do you need to begin serving?

Do you need to take a step of generosity?

Whatever that next step may be, don't ignore the Spirit's leading.

A thriving church is built one faithful step of obedience at a time.

Sermon Notes & Further Study

Steadfastly

4201. προσκαρτερέω proskartereō verb

Adhere firmly to, persist in, remain devoted to.

Exalting Jesus in Acts

Before jumping into verse 42, let’s pause to remember how this church was born. Peter preached a Christ-exalting sermon, and as a result of the Spirit and the Word at work, three thousand people were saved.

The church is God’s plan. That plan is bigger than the random conversion of a few individuals. Christianity is personal but not individualistic. It’s corporate. Jesus is saving a people for himself (Titus 2:14).

In this Spirit-filled congregation the people didn’t abandon study of the Word because the Spirit was at work. If you’re walking in the fullness of the Spirit, you will be drawn to the Bible.

3. Additional Questions (Using Logos Study Assistant✨)

What are ten marks of a healthy church demonstrated by the church in Acts which apply today?

Healthy churches today require devotion to apostolic teaching about Jesus, shared life and resources through fellowship, communion at the Lord’s Table, and corporate and individual prayer.[1] Modern congregations should maintain eager commitment to learning Scripture and correct doctrine, drawing from the New Testament as the apostles’ teachings handed down to us.[1]

2. Grounded in right thinking about God and others, church members care for one another’s material needs, motivated by the joy of Christ to make sacrifices for fellow believers.[1]

3. Daily worship and mutual love overflow into evangelism as part of ordinary life, creating public favor that draws people to faith.[1]

4. Healthy churches pay careful attention to teaching, fellowship, prayer, and witness.[2]

5. Churches thrive when unified around one central purpose—reaching the world for Christ—pulling together toward fulfilling the Great Commission.[3]

6. Regular gathering together in community prevents isolation and strengthens corporate life.[3]

7. Believers pray together constantly, joining in prayer for shared spiritual concerns.[3]

8. Churches pursue together the same spiritual disciplines—apostolic teaching, fellowship, breaking of bread, and prayer—studying God’s truth, holding Christ’s person, worshiping His glory, and seeking His grace in unison.[3]

9. True church growth remains consistently connected to the spreading of God’s Word.[1]

10. Churches grow in the fear of the Lord and in the comfort of the Holy Spirit.[1]

4. Bible Translation

I’m choosing the NKJV for preaching because I believe it offers the strongest balance of faithfulness to the historic text of Scripture, clarity for modern readers, and continuity with the church’s worshiping tradition.

At the same time, I deeply value other faithful translations—such as the NASB, ESV, CSB, and NIV—which also serve the church well and can enrich our understanding of God’s Word.
