Acts 3-12
If you have your Bible, turn to Acts chapter three. We are in the middle of a series called Generations, where we’ve been trying to teach through an overview of Scripture, and we have completely run ashore in the book of Acts. The book of Acts is one of the most profound books in our New Testament because it shows us what was technically titled “The Acts of the Apostles,” but is really the Acts of the Holy Spirit. Page after page, it shows us what God intended for His church—the people of God.
In the early chapters, we begin to see the fledgling church as it first gathers: the church undefiled. This is the church before pastors in choir robes and pipe organs that nobody ever plays. This is the church before it all got complicated—just the raw simplicity of the church. These people were committed to four basic things: the apostles’ teaching, fellowship, the breaking of bread, and prayer. And God brought people literally by the thousands to a simple communication that Jesus is the Christ, and to a community of people living lives that reflected His glory. That was all the church was. Their calendars were simple, their lives were simple, their godliness was undeniable, and people came by the thousands.
Ceilings of Complexity
Now, with any organization, church, or movement, the leader prays that people will come. The leader longs for people to come, and then they do. And then the question is: how do you adjust to what God is doing?
People often talk about “growing a church.” I don’t think you can grow a church. We can plant and we can water, but God is the one who causes the growth. God chooses to grow a church, and our responsibility is simply to make room as He does. But what do you do when He actually does it?
I remember in the early days when we started this church, there were about forty college students. We said, “Let’s see what happens. We’ll just teach the Word, try to live authentically, and see what God does.” And God began to bring people, which was great because we had prayed for it. But then God kept bringing people. The very thing we had prayed for became the very thing that kept me up at night. I realized early on that the way we had set things up was completely unsustainable long-term.
When you start doing the math, you realize most senior pastors don’t stay at the church they start. Most senior pastors end up at a church for three to five years and then leave. I looked at that and said, “I don’t want to do that. If anything, I want the opposite.” I saw pastors who stayed at their church for thirty, forty, or fifty years, and I said, “That’s what I want to do.”
The reason those pastors are able to do that is because they learn over time that as the church grows, the game changes. And because the game changes, the rules change. If you don’t know what game you’re playing, you will find yourself in complete distress.
Years ago, I came across a concept called “ceilings of complexity,” and it opened my eyes to why we feel tension at specific growth points. When there are 50 people versus 500 people, it is a completely different game. Three major things must change as an organization grows:
- The way of relating has to change.
- The organizational structure has to change.
- The leader and the people have to change.
Now, I don’t know about you, but I love change—as long as it was my idea! But when growth comes, change is upon you whether you want it or not.
Ceilings of complexity illustrate this well. Most organizations start out like a cross-country runner—one person with way too much time on their hands to talk to themselves, dreaming up what they want to accomplish.
Then people join, and the game shifts to a golf foursome. In a foursome, everybody sees where everybody’s ball goes. You walk up to your ball and ask, “Should I hit a seven-iron or an eight-iron?” And your buddy says, “I like the eight-iron; you’ve been hitting that great today.” You talk smack together, you contribute together, and information is completely shared.
Then growth pushes you through another ceiling, and suddenly you are playing as a basketball team. You have five players on the court and five or six on the bench. The coach calls a play, and everybody hears it because they are right there on the sidelines. You have a point guard with good handles calling the floor, and a giant oak tree at center. Each has a unique role, but information is still broadly shared. If someone gets hurt, a teammate can step in because they understand the whole system.
Then the game changes again, and that structure can no longer handle the weight. Now you are a football team. The offense and the defense travel to the stadium on different buses. While the offense is on the field, the defense is on the sideline listening to their coordinator. You have coaches up in the press box who aren’t even down on the field feeling the hits; they have a different vantage point, calling down adjustments that the players must trust. And if the left tackle gets hurt, the defensive back on the bench doesn’t have a clue how to play that position. That is why you have over fifty players on the roster instead of eleven.
The game changes. If you don’t know what game you’re playing, you won’t know the rules, and you will experience constant friction. That is exactly what the early church experiences in Acts chapters 3 through 12. These chapters are about the purging and the maturation of the church as they figure out what it means to do life together when it’s no longer just a handful of disciples, but thousands upon thousands of believers.
Uneducated Men with Undeniable Godliness
As we move into Acts chapter 3, Peter and John take center stage. Peter remains the primary focal point of the narrative all the way through chapter 10, where the focus will begin shifting to another figure who will shape the future of Christianity.
In chapter 3, Peter and John head up to the temple at the hour of prayer. They heal a man who was lame from birth, and the entire crowd is astonished. Peter immediately redirects the crowd’s attention in verse 19, pointing them away from themselves to the true source of the miracle: Jesus Christ.
By chapter 4, the church has exploded. The number of men alone grew to about 5,000, not counting women and children.
Acts 4:4 (NASB)
But many of those who had heard the message believed; and the number of the men came to be about five thousand.
Peter stands before the religious council and boldly proclaims the exclusivity and power of Christ.
Acts 4:12 (NASB)
‘And there is salvation in no one else; for there is no other name under heaven that has been given among men by which we must be saved.’
In verse 13, the religious leaders give Peter and John what amounts to a backhanded compliment:
Acts 4:13 (NASB)
Now as they observed the confidence of Peter and John and understood that they were uneducated and untrained men, they were amazed, and [began] to recognize them as having been with Jesus.
These leaders recognized that Peter and John lacked formal rabbinic credentials, yet their godliness and boldness were undeniable because they had been with Jesus. When the council commands them to stop speaking in the name of Jesus, Peter and John deliver that famous response:
Acts 4:19-20 (NASB)
But Peter and John answered and said to them, ‘Whether it is right in the sight of God to give heed to you rather than to God, you be the judge; for we cannot stop speaking about what we have seen and heard.’
They weren’t trying to impress the crowds with polished oratory; they simply bore witness to what they had seen and heard.
Generosity, Hypocrisy, and the Purging of the Church
At the end of chapter 4, we see incredible generosity among the believers. Remember, many people had traveled from all over the known world for Pentecost. After witnessing the Holy Spirit poured out and hearing the gospel, they chose to stay in Jerusalem to learn and grow. As resources dwindled, believers began selling property to care for one another.
In chapter 4, verse 36, we meet a man named Joseph, whom the apostles called Barnabas, meaning “Son of Encouragement.” Barnabas sells a field he owns and lays the entire proceeds at the apostles’ feet to distribute to anyone in need.
Well, other people saw the honor Barnabas received, and in chapter 5, a couple named Ananias and Sapphira decide they want the same applause. They sell a piece of property, conspire to keep back part of the money for themselves—maybe to buy a new flat screen—and bring the rest to Peter, claiming it was the full sale price.
Peter confronts Ananias: “Is this the whole price?” Ananias says yes, and falls down dead on the spot. About three hours later, his wife Sapphira walks in, unaware of what happened. Peter asks her the same question, she repeats the lie, and she drops dead beside him. Not surprisingly, great fear seized the entire church.
Why did God deal with them so severely? Because God was making a definitive statement at the foundation of the church: true spirituality is not about external appearance; it is about internal reality. Ananias and Sapphira were under no obligation to give the money. They could have given a fraction and honestly said, “We’re giving ten percent,” and God would have received it. Their sin was deceit—pretending to be wholly surrendered on the outside while remaining selfish on the inside. God purged the church to protect its purity.
Signs and wonders continued through the apostles, and multitudes continued to turn to the Lord.
Acts 5:14 (NASB)
And all the more believers in the Lord, multitudes of men and women, were constantly added to [their number],
Building Teams to Address Ceilings of Complexity
Because the church was multiplying rapidly, structural strain surfaced immediately in chapter 6. Two groups of widows were present: Hellenistic (Greek-speaking) Jewish widows and Hebraic (Hebrew-speaking) Jewish widows. The Greek-speaking widows were being overlooked in the daily distribution of food.
The apostles faced a critical leadership decision: should they stop preaching and personally serve the tables to ensure fairness, or should they adjust their structure?
They recognized their primary calling was prayer and the ministry of the Word. Rather than trying to do everything themselves, they empowered the community to select seven men full of the Spirit and wisdom to oversee the food distribution. The first man listed is Stephen.
Acts 6:5 (NASB)
The statement found approval with the whole congregation; and they chose Stephen, a man full of faith and of the Holy Spirit, and Philip, Prochorus, Nicanor, Timon, Parmenas and Nicolas, a proselyte from Antioch.
The apostles built teams around their weaknesses so they could focus on their core strengths. Look at the result of that structural shift:
Acts 6:7 (NASB)
The word of God kept on spreading; and the number of the disciples continued to increase greatly in Jerusalem, and a great many of the priests were becoming obedient to the faith.
Because the apostles stayed faithful to studying, praying, and teaching, even a great many of the Jewish priests became obedient to the faith.
The First Martyr and the Scatter Pattern
Stephen soon found himself in fierce debates with opposition from various synagogues. When they couldn’t withstand his wisdom, they brought false charges against him. In chapter 7, Stephen delivers a sweeping survey of Israel’s history—from Abraham to Moses, through the tabernacle and Solomon’s temple.
For most of the speech, it looks like a typical theological debate. But in verse 51, Stephen stops dancing and lands a direct blow:
Acts 7:51 (NASB)
’You men who are stiff-necked and uncircumcised in heart and ears are always resisting the Holy Spirit; you are doing just as your fathers did.
Enraged, the council drags Stephen outside the city and stones him. As he dies, Stephen looks up and sees the heavens opened and Jesus standing at the right hand of God, as if giving a standing ovation to His faithful servant. The witnesses lay their coats at the feet of a young man named Saul.
Acts 8:1 (NASB)
Saul was in hearty agreement with putting him to death. And on that day a great persecution began against the church in Jerusalem, and they were all scattered throughout the regions of Judea and Samaria, except the apostles.
Remember Jesus’ words in Acts 1:8? He told them they would be His witnesses in Jerusalem, Judea, Samaria, and to the ends of the earth. From chapter 1 through chapter 7, where have they stayed? Exclusively in Jerusalem! It took severe persecution to scatter the believers into Judea and Samaria, propelling them into the very mission God had ordained.
The Conversion and Obscurity of Saul
In chapter 9, Saul is breathing murderous threats against the disciples. He secures letters from the high priest to travel north to Damascus, intending to extinguish the movement before it spreads further. On the road, a blinding light knocks him to the ground, and a voice cries out:
Acts 9:4-5 (NASB)
and he fell to the ground and heard a voice saying to him, ‘Saul, Saul, why are you persecuting Me?’ And he said, ‘Who are You, Lord?’ And He [said], ’I am Jesus whom you are persecuting,
Can you imagine the terror of that moment? Saul realized that in his religious zeal, he was persecuting the very Messiah he claimed to serve.
We often assume Saul was converted and immediately stepped onto the world stage as the apostle Paul. But Scripture reveals he spent roughly a decade in obscurity. He went into Arabia, spent years re-reading his Old Testament in light of the resurrected Christ, and returned to his hometown of Tarsus to serve quietly before God elevated him. In that hiddenness, God prepared the man who would write much of the New Testament.
God told a reluctant disciple named Ananias to go lay hands on Saul:
Acts 9:15-16 (NASB)
But the Lord said to him, ‘Go, for he is a chosen instrument of Mine, to bear My name before the Gentiles and kings and the sons of Israel; for I will show him how much he must suffer for My name’s sake.’
Dismantling Old Paradigms: Peter and Cornelius
In Acts chapter 10, the church encounters another massive ceiling of complexity: the inclusion of Gentiles. For centuries, Jewish worship was centralized in Jerusalem, around the temple, administered by a Levitical priesthood, and separated from the Gentiles by strict dietary and ceremonial laws.
Peter is staying in Joppa. While praying on a rooftop around lunchtime, he falls into a trance and sees a sheet descending from heaven filled with unclean animals. A voice commands, “Arise, Peter; kill and eat.” Peter objects, “Lord, I have never eaten anything common or unclean.” The voice answers:
Acts 10:15 (NASB)
Again a voice [came] to him a second time, ‘What God has cleansed, no [longer] consider unholy.’
This happens three times before the sheet is taken up. Immediately, men arrive from Caesarea sent by Cornelius, a Roman centurion. Peter accompanies them, enters a Gentile home, and realizes the vision wasn’t primarily about food—it was about people.
Acts 10:34-35 (NASB)
Opening his mouth, Peter said: ’I most certainly understand [now] that God is not one to show partiality, but in every nation the man who fears Him and does what is right is welcome to Him.
As Peter preaches Christ to them, the Holy Spirit falls upon the Gentiles just as He had upon the Jewish disciples at Pentecost.
When Peter returns to Jerusalem in chapter 11, the circumcised believers criticize him for eating with uncircumcised men. Peter explains everything God did, and the church finally comes to a stunning realization:
Acts 11:18 (NASB)
When they heard this, they quieted down and glorified God, saying, ‘Well then, God has granted to the Gentiles also the repentance [that leads] to life.’
Meanwhile, the gospel reaches Antioch in Syria, and large numbers of Greeks believe. Jerusalem sends Barnabas to investigate. When Barnabas arrives, he rejoices at what he sees, but he recognizes he needs help teaching this growing Gentile flock. He travels to Tarsus, finds Saul, and brings him back to Antioch. Together, they disciple that church for an entire year. It was in Antioch that the disciples were first called Christians.
Thriving Under Fire
In chapter 12, King Herod Agrippa begins violently persecuting the church. He executes James, the brother of John, with the sword. Seeing that it pleased the people, he arrests Peter during the Feast of Unleavened Bread and places him under heavy guard.
The church gathers in a home to pray fervently for Peter. In the middle of the night, an angel breaks Peter out of prison—chains falling off, iron gates opening on their own. Peter walks straight to the house where the prayer meeting is happening and knocks on the door.
A servant girl named Rhoda comes to the door, recognizes Peter’s voice, and is so overjoyed that she forgets to open the door! She runs back to the prayer group and shouts, “Peter is standing at the gate!” And these believers—who had been praying for his release—tell her, “You are out of your mind. It must be his angel!”
Peter keeps knocking, they finally open the door, and they are astonished. Peter explains how the Lord rescued him and departs for another place.
Look at how Luke summarizes this season:
Acts 12:24 (NASB)
But the word of the Lord continued to grow and to be multiplied.
Throughout the book of Acts, whenever pressure mounts against the church, the church does not crumble; it multiplies. Persecution purifies and spreads the church. Apathy, indifference, and comfort are far more dangerous to our faith than opposition.
Stop Going to Church—Be the Church
As the church broke through each ceiling of complexity, three things had to continually adjust: their way of relating, their organizational structure, and their leadership paradigms. They moved from a centralized system in Jerusalem to a decentralized movement of the Holy Spirit across the nations. They realized that in Christ, we are all a kingdom of priests. We don’t go to a temple; we are the temple. We don’t offer animal sacrifices; our lives are living sacrifices.
The great tragedy of Western Christianity is that we often try to smother this movement under institutional complacency. We reduce Christianity to an event we attend rather than an identity we live. We say, “I go to church,” instead of “I am the church.” We point to a pastor and say, “That’s the minister,” forgetting that every follower of Jesus is called to ministry.
God did not call us to outsource our spiritual responsibility to professionals. He entrusted the gospel to regular, uneducated, everyday believers who were completely surrendered to Jesus, and through them, He turned the world upside down.
He has entrusted that exact same gospel to you. Where are you taking it?
When the story of your life is told and your spiritual legacy is evaluated, what will be said? Will people say, “He was a nice guy,” or “She was pleasant”? Or will someone stand up and say, “I know Jesus Christ today because that person loved me, served me, and shared the gospel with me”?
The choice is yours.
Let’s pray.
Father, we ask that You would stir within us a greater affection for Jesus. May our lives genuinely reflect Your glory. Like those early believers, move us so deeply by the gospel that we refuse to sit on the sidelines as passive observers. Help us discover our gifts, embrace our calling, and participate in what You are doing in our city and across the world. When our days on earth are finished, may our legacy be one of faithfulness to Your Word, love for our neighbors, and bold proclamation of the name of Jesus. In His name we pray, Amen.
