They Devoted Themselves: The Challenge of Acts 2:42

There are few descriptions of the early church more familiar than Acts 2:42, yet familiarity can cause us to miss the weight of Luke’s words: “And they devoted themselves to the apostles’ teaching and the fellowship, to the breaking of bread and the prayers” (Acts 2:42, ESV). Luke does not merely tell us that these Christians attended, appreciated, or participated in these whenever their schedules permitted. He says “they devoted themselves.” That phrase describes persistence, steadfastness, and continuing commitment. The verb Luke uses carries the sense of persisting in, adhering to, or continuing steadfastly in something. It is used elsewhere of believers persisting in prayer and of the apostles devoting themselves to prayer and the ministry of the Word. Christianity, therefore, was not simply something these first believers added to their existing lives. Jesus had become the center around which their lives were now ordered. That is precisely why Acts 2 presents such a serious challenge to the casual Christianity that has become comfortable in many churches today.

We must first remember who these devoted people were and what had just happened to them. Pentecost was not an ordinary religious gathering. The promised Holy Spirit had been poured out, Peter had stood before the crowds and proclaimed the crucified and risen Christ, and the people had been confronted with their guilt before God. Peter declared, “Let all the house of Israel therefore know for certain that God has made him both Lord and Christ, this Jesus whom you crucified” (Acts 2:36, ESV). When the people were cut to the heart and asked what they should do, Peter commanded them to repent and be baptized in the name of Jesus Christ. About three thousand received the word and were baptized (Acts 2:37–41). Acts 2:42 describes what happened after the gospel took hold of them. Their devotion did not purchase salvation; their devotion was the fruit of salvation. Grace did not produce indifference. Grace produced a people whose priorities had been radically reordered around Jesus.

This distinction is essential because biblical Christianity must never turn devotion into a means of earning acceptance with God. We are justified by grace alone through faith alone in Christ alone, not because we attend enough services, pray enough prayers, or perform enough Christian duties. But know that the same grace that saves sinners also changes them. The Holy Spirit does not regenerate a person so that they can comfortably continue living as though Christ were insignificant. Paul writes, “Therefore, if anyone is in Christ, he is a new creation” (2 Corinthians 5:17, ESV). Acts 2 shows us that one evidence of this new life is a new devotion. These first believers had encountered the risen Christ through the preaching of the gospel, received the Holy Spirit, and were incorporated into Christ's people. Their devotion was not an attempt to become Christians. They devoted themselves because Christ had already claimed them as His own.

Notice also what received their devotion. They devoted themselves “to the apostles’ teaching and the fellowship, to the breaking of bread and the prayers.”. There is no mention of elaborate programs, impressive productions, carefully constructed entertainment, or charismatic personalities. The church that would eventually carry the gospel throughout the Roman world was built around the Word of God, the people of God, worship centered upon Jesus, and prayer. The apostles’ teaching centered upon Jesus and explained how the Scriptures found their fulfillment in Him. Their fellowship involved genuine participation in one another's lives, including practical care for those in need. Their breaking of bread expressed life together and remembrance of Christ, while prayer demonstrated their dependence upon God. The early church did not possess the machinery that modern churches sometimes believe necessary for effectiveness. They possessed the gospel, the Scriptures, the Spirit, prayer, and one another ~ and that was enough to turn their world upside down.

This confronts one of the dangerous assumptions that can quietly enter the modern church: that church growth depends primarily upon programs, personalities, entertainment, or cultural relevance. Acts 2 teaches something altogether different. The church advances through Spirit-empowered, Christ-centered, Scripture-saturated gospel proclamation. Peter did not entertain Jerusalem into the kingdom of God. He preached Jesus. He opened the Scriptures. He confronted sin. He announced the resurrection. He called sinners to repentance. The Holy Spirit worked through that proclamation, and thousands were converted. Then those converted people devoted themselves to the very truth through which they had come to know Jesus. The pattern is unmistakable: the Word is proclaimed, the Spirit gives life, sinners repent and believe, believers are gathered into the church, and the church continues steadfastly in the Word.

This means that devotion to the apostles’ teaching must remain at the heart of the church. We possess that apostolic testimony today in the inspired Scriptures. The church does not need a new message for a new generation. We need renewed confidence in the message God has already given us. The apostles taught these new Christians who Jesus was, what He had accomplished, what His resurrection meant, and how those redeemed by Him must now live. That apostolic teaching would have included Jesus's ministry, death, resurrection, exaltation, and the implications of those realities for salvation and godly living. A church cannot be more devoted to Christ while becoming less devoted to His Word. If our Bibles remain closed while our calendars remain full, something is terribly wrong. The church does not need Christians who merely admire Scripture. We need Christians who submit themselves to it, learn it, obey it, teach it to their children, and carry its gospel to their neighbors.

But Luke does not say that each believer privately devoted himself to spiritual disciplines. He says “they devoted themselves.” Christianity in Acts 2 is unmistakably corporate. Conversion brought people not merely into a private relationship with Jesus but into the visible community of His people. Fellowship (koinonia) describes genuine participation and mutual involvement, rooted ultimately in the believers' common relationship with Jesus. This is why the casual attitude that says, “I love Jesus, but I do not really need the church,” is so foreign to Acts. Jesus did not merely save three thousand isolated individuals at Pentecost. He gathered a people. To belong to Christ is to belong to Christ's body. The Christian who deliberately treats the local church as optional is attempting to separate what the New Testament repeatedly joins together.

Acts 2 forces us to examine what place the church actually occupies in our lives. For many Christians, church involvement has quietly become one activity among many. We attend when nothing more pressing competes with it. We serve when it is convenient. We fellowship when we have sufficient time. We pray when circumstances become desperate. We evangelize when an unusually obvious opportunity appears. But that is not the picture Luke gives us. Verse 46 says, “And day by day, attending the temple together and breaking bread in their homes” (Acts 2:46, ESV). Their circumstances were certainly different from ours, and Scripture does not command every congregation to reproduce their precise daily schedule. But we dare not use that distinction to escape the principle. Their Christianity had become the organizing reality of their lives. Jesus was not fitted around everything else. Everything else had to be fitted around Jesus.

And this devotion was inseparable from the mission of the church. Acts 2 begins with Jesus's followers receiving the promised Holy Spirit and ends with the gospel continuing to advance. Jesus had already told His disciples, “But you will receive power when the Holy Spirit has come upon you, and you will be my witnesses” (Acts 1:8, ESV). The Spirit was not given merely so Christians could enjoy extraordinary spiritual experiences. The Spirit empowered Jesus's people to bear witness to Christ. Peter immediately demonstrates this at Pentecost: the Spirit comes, Peter preaches, Christ is proclaimed, sinners repent, and the church grows. Evangelism, therefore, cannot be separated from the Spirit-filled life of the church. A Spirit-empowered church will be a Christ-proclaiming church.

This destroys another dangerous assumption: that evangelism is primarily the responsibility of pastors, missionaries, or unusually gifted Christians. The Great Commission was entrusted to the church. Jesus commanded His followers, “Go therefore and make disciples of all nations” (Matthew 28:19, ESV). Every Christian may not preach publicly like Peter. Every Christian may not cross an ocean as a missionary. Every Christian may not possess the same gifts. But every Christian belongs to the people whom Christ has commissioned to make disciples. Your home is a mission field. Your workplace is a mission field. Your school is a mission field. Your neighborhood is a mission field. Your family contains people who will one day stand before God. The church exists to glorify God and make disciples

This is precisely where casual church involvement becomes more dangerous than we often realize. Casual Christianity does not merely weaken our attendance; it weakens our witness. A believer who is rarely under the Word will be poorly equipped to explain the Word. A believer disconnected from Christian fellowship will lack the encouragement and accountability necessary for faithful witness. A believer who neglects prayer will attempt spiritual work through human strength. And a believer whose schedule consistently communicates that Christ's church is secondary will find it difficult to convince an unbelieving neighbor that Christ Himself is supreme. The world does not need Christians who simply tell people that Jesus matters. It needs Christians whose lives demonstrate that Jesus is Lord.

We should also notice the remarkable connection between the devotion of the church and the witness of the church at the end of Acts 2. Luke tells us that they were “praising God and having favor with all the people. And the Lord added to their number day by day those who were being saved” (Acts 2:47, ESV). Luke does not present devotion and evangelism as competitors. The church did not have to choose between discipleship and mission. Their devotion to biblical teaching, fellowship, worship, generosity, and prayer formed a community in which the gospel was both proclaimed and displayed. Their shared life testified that Jesus had actually done something among them. And yet Luke makes clear who deserves the glory: “the Lord added to their number.” The church proclaimed; God saved. The believers witnessed; God opened hearts. They labored faithfully, but salvation belonged to the Lord. Acts 2 moves from the believers' common devotion to Jesus to the Lord's continuing work of saving and adding people to His community.

That truth should produce both confidence and urgency in evangelism. Confidence, because converting sinners is ultimately God's work. We cannot regenerate a heart. We cannot raise the spiritually dead. We cannot argue someone into the kingdom of heaven. Salvation belongs to the Lord. But that sovereignty does not produce passivity; it produces courage. The sovereign God has ordained the proclamation of the gospel as the means through which sinners hear of Jesus. Paul asks, “And how are they to believe in him of whom they have never heard? And how are they to hear without someone preaching?” (Romans 10:14, ESV). We proclaim because God saves through the gospel. We pray because God alone can open hearts. We go because Christ commanded us to go. The sovereignty of God is not an excuse for silence; it is the foundation of missionary confidence.

And the matter is urgent because eternity is real. The people around us are not just struggling individuals who need better habits, stronger marriages, improved finances, or greater emotional stability. They are sinners who need reconciliation with a holy God. Scripture declares, “for all have sinned and fall short of the glory of God” (Romans 3:23, ESV), and “the wages of sin is death” (Romans 6:23, ESV). Yet the gospel announces that the Son of God took on flesh, lived the righteous life we have failed to live, bore the wrath sinners deserve upon the cross, rose bodily from the grave, ascended to heaven, and reigns as Lord. Therefore, “everyone who calls upon the name of the Lord shall be saved” (Acts 2:21, ESV). This is the message entrusted to us. How can we possess such news and remain silent? How can we believe judgment is coming, Jesus saves, eternity is real, and the gospel is God's power for salvation ~ and still treat the Great Commission as optional?

Perhaps, then, the question Acts 2:42 places before us is not simply, “Do I attend church?” The deeper question is, “What am I devoted to?” Our calendars answer that question. Our spending answers it. Our conversations answer it. Our priorities answer it. Our willingness to serve answers it. Our prayer lives answer it. Our concern for unbelieving neighbors answers it. Everyone is devoted to something. The tragedy occurs when people profess that Jesus Christ is Lord while arranging their lives as though almost everything else deserves greater commitment. Jesus did not die merely to occupy a convenient portion of our week. Paul reminds us, “You are not your own, for you were bought with a price. So glorify God in your body” (1 Corinthians 6:19–20, ESV). The blood of Jesus has purchased a people who now belong entirely to Him.

Therefore, Acts 2:42 is not just a beautiful description of what the church used to be; it is a searching challenge concerning what Christ's church ought to be ~ what it must be. We should be a people devoted to Scripture because we long to hear our Master's voice. We should be devoted to fellowship because Jesus has joined us to His body. We should be devoted to worship because the crucified and risen King deserves our praise. We should be devoted to prayer because apart from God's power our labor accomplishes nothing of eternal consequence. And we should be devoted to evangelism because Jesus has commissioned His church to make disciples of all nations. The first believers did not treat the church as one activity among many. “They devoted themselves.” May God deliver us from a Christianity of convenience and make us a people whose lives declare that Jesus is worthy of everything. The fields are still ripe for harvest. The gospel is still the power of God for salvation. Jesus is still building His church. And until our risen King returns, we have work to do.
