Question 1

What exactly happened at Pentecost, and why was it the defining moment in history?

Accepted Answer

Pentecost (from the Greek for "fiftieth") was a Jewish harvest festival held 50 days after Passover. On this day, approximately AD 30, something unprecedented occurred: the Holy Spirit descended on the 120 disciples gathered in Jerusalem, accompanied by a sound like rushing wind and what appeared to be tongues of fire. The disciples immediately began speaking in the languages of the diaspora Jews gathered in Jerusalem from every nation. Three thousand people were baptized that day. Pentecost is the fulfillment of Joel's prophecy (Joel 2:28–32) and Jesus's promise (Acts 1:8). It marks the transition from the age of the law to the age of the Spirit — God's presence no longer confined to a temple building but now dwelling in his people. The church was not organized into existence; it was born by the Spirit. "When the day of Pentecost came, they were all together in one place." — Acts 2:1 (NIV)

Question 2

How do I experience the Holy Spirit today? Is what happened at Pentecost still available to believers now?

Accepted Answer

Peter's Pentecost sermon answers this directly: "Repent and be baptized, every one of you, in the name of Jesus Christ for the forgiveness of your sins. And you will receive the gift of the Holy Spirit. The promise is for you and your children and for all who are far off" (Acts 2:38–39). The gift of the Spirit is not limited to the first century — it is for all who are far off, which includes every generation since. The specific manifestations at Pentecost (tongues, wind, fire) were signs marking a unique historical moment — the inauguration of the new covenant age. But the Spirit himself — as guide, comforter, empowerer, and sanctifier — is the ongoing inheritance of every believer. The question is not whether the Spirit is available but whether we are attentive to his presence and responsive to his leading. "The promise is for you and your children and for all who are far off." — Acts 2:39 (NIV)

Question 3

Why does Acts begin with the ascension rather than the resurrection, and what does this tell us about Luke's purpose?

Accepted Answer

Luke's Gospel ends with the ascension; Acts begins with it. This is not repetition but theological framing. The ascension is the hinge between the two volumes: Jesus's earthly ministry is complete; now his heavenly ministry begins through the Spirit and the church. Luke's purpose in Acts is to show that the gospel's spread from Jerusalem to Rome is not accidental but divinely orchestrated. By opening with the ascension and the commission of Acts 1:8, Luke establishes the entire book as the fulfillment of Jesus's final command. The church does not act on its own initiative — it is sent, sustained, and directed by the risen and ascended Lord through his Spirit. "After he said this, he was taken up before their very eyes." — Acts 1:9 (NIV)

Question 4

What made Paul's conversion so significant, and why does Luke tell it three times in Acts?

Accepted Answer

Saul of Tarsus was not a passive bystander to Stephen's stoning — he was its approving witness (Acts 7:58; 8:1). He then launched a systematic campaign to destroy the church, entering houses and dragging men and women to prison (8:3). His conversion on the Damascus road is therefore not just a personal transformation but a theological statement: if the gospel can reach Saul, it can reach anyone. Luke tells Paul's conversion three times (Acts 9, 22, 26) — each retelling emphasizing a different audience and theological point. This repetition signals its central importance to the book's argument. Paul himself later describes his conversion as evidence that Jesus is truly risen: "He appeared to me also, as to one abnormally born" (1 Corinthians 15:8). The persecutor becomes the apostle; the destroyer becomes the builder. "Saul, Saul, why do you persecute me?" — Acts 9:4 (NIV)

Question 5

Peter's vision in Acts 10 told him that nothing God has made is unclean. How does this apply to how I view people who are different from me?

Accepted Answer

Peter's vision (Acts 10:9–16) uses food laws as a symbol for something much larger: the barrier between Jew and Gentile has been abolished in Christ. When Peter arrives at Cornelius's house, he says: "I now realize how true it is that God does not show favoritism but accepts from every nation the one who fears him" (10:34–35). The vision is not primarily about dietary laws — it is about people. The principle is radical: no person is to be called common or unclean (10:28). This has direct implications for how believers relate to people of different ethnicities, social classes, and backgrounds. The gospel creates a community where the normal human categories of clean/unclean, insider/outsider, worthy/unworthy are overturned. "Do not call anything impure that God has made clean." — Acts 10:15 (NIV)

Question 6

The Jerusalem Council (Acts 15) is sometimes called the first church council. What was at stake, and why does its decision still matter today?

Accepted Answer

The question before the Jerusalem Council was existential: must Gentiles become Jews (through circumcision and Torah observance) in order to be saved? If yes, Christianity is a sect of Judaism. If no, it is a universal faith accessible to all humanity without ethnic or cultural preconditions. The council's decision — that Gentiles are saved by grace through faith, not by observing the law — is the theological foundation of Paul's letters to the Romans and Galatians. It established that the gospel is not a cultural package but a message that can be received by people of every nation without requiring them to adopt a foreign culture. This decision still matters because it defines the nature of the gospel itself: it is for everyone, as they are, where they are. "We believe it is through the grace of our Lord Jesus that we are saved." — Acts 15:11 (NIV)

Question 7

Paul's Areopagus speech is often called the greatest example of contextual evangelism. What made it so effective?

Accepted Answer

When Paul arrived in Athens, he did not begin with Scripture (his audience had none) or with Jewish history (irrelevant to Greeks). Instead, he began with what they already knew and valued: their own religious instincts (the altar to the unknown god), their own philosophers (Epimenides and Aratus), and their own experience of being human. Paul's strategy was to find the point of genuine contact between the gospel and his audience's existing framework, then use that contact point to introduce what they did not know: the resurrection. He did not compromise the message — he translated it. The result was mixed (some mocked, some believed, some wanted to hear more) but the approach was masterful. It models a principle that remains essential: effective witness requires genuine understanding of the person you are speaking to. "For in him we live and move and have our being." — Acts 17:28 (NIV)

Question 8

Acts ends with Paul under house arrest, still preaching. How do I maintain purpose and witness when my circumstances are severely limited?

Accepted Answer

Paul's final two years in Rome are described in two verses (28:30–31), but those verses contain one of the most powerful phrases in the book: "with all boldness and without hindrance." Under house arrest, chained to guards, awaiting trial before Caesar, Paul received everyone who came to him and proclaimed the kingdom of God. The key insight is that Paul did not wait for his circumstances to improve before he began his witness. He worked within his constraints rather than against them. The guards became his congregation; his visitors became his audience. This models a principle that appears throughout Acts: the gospel advances not despite limitations but through them. Constraints define the shape of the witness, not its possibility. "He proclaimed the kingdom of God... with all boldness and without hindrance!" — Acts 28:31 (NIV)

Question 9

Why does Acts end so abruptly, without telling us what happened to Paul? Is this a literary flaw or intentional?

Accepted Answer

Luke almost certainly knew the outcome of Paul's trial when he wrote Acts — yet he chose not to include it. This is deliberate literary strategy, not oversight. The book ends not with Paul's fate but with the gospel's advance: "with all boldness and without hindrance." The abrupt ending serves Luke's theological purpose: Acts is not a biography of Paul but a history of the gospel's unstoppable expansion. By ending mid-story, Luke signals that the story is not finished — it continues in every generation of believers. The reader is invited to ask: what is my chapter in this story? Where is the gospel advancing through my witness? The open ending is an open invitation. "He proclaimed the kingdom of God... with all boldness and without hindrance!" — Acts 28:31 (NIV)

Question 10

What is the theological significance of the 3,000 baptisms on Pentecost day?

Accepted Answer

The number 3,000 is not incidental. At Mount Sinai, when Israel worshipped the golden calf, approximately 3,000 people died under the judgment of the law (Exodus 32:28). On Pentecost, 3,000 people were added to the church through the gift of the Spirit. Luke’s audience, steeped in Scripture, would have recognized this as a deliberate reversal. The law at Sinai brought death; the Spirit at Pentecost brings life. This is precisely Paul’s argument in 2 Corinthians 3: the old covenant was a ministry of death written on stone, but the new covenant is a ministry of the Spirit that gives life. Pentecost is not just the birthday of the church — it is the inauguration of the new covenant age, the fulfillment of Jeremiah’s promise that God would write his law on hearts rather than stone (Jeremiah 31:33). “Those who accepted his message were baptized, and about three thousand were added to their number that day.” — Acts 2:41 (NIV)

Question 11

The early church devoted themselves to four things (Acts 2:42). What would it look like to apply this pattern in a modern church or small group?

Accepted Answer

Acts 2:42 describes the early church’s four core practices: the apostles’ teaching, fellowship, breaking of bread, and prayer. These are not programs — they are the organic rhythms of a community shaped by the Spirit. Apostles’ teaching: serious, ongoing engagement with Scripture, not just inspirational messages. Fellowship (koinŏnia): shared life, not just attendance at the same event. Breaking of bread: regular communion that remembers Christ’s death and anticipates his return. Prayer: corporate dependence on God, not just private devotion. A modern small group that practices all four — studying Scripture together, sharing real life, eating together, and praying together — is closer to the New Testament pattern than most church programs. “They devoted themselves to the apostles’ teaching and to fellowship, to the breaking of bread and to prayer.” — Acts 2:42 (NIV)

Question 12

Why did Peter quote Joel 2 at Pentecost, and what does “the last days” mean in that context?

Accepted Answer

Peter’s opening words are striking: “This is what was spoken by the prophet Joel: ‘In the last days, God says, I will pour out my Spirit on all people.’” The phrase “the last days” does not mean “the end of the world is near.” It means the final era of redemptive history has begun — the age inaugurated by Christ’s death, resurrection, and the gift of the Spirit. The New Testament consistently uses “last days” to describe the present age between Christ’s first and second coming (Hebrews 1:2; 1 Peter 1:20; 1 John 2:18). Peter is saying: the age Joel prophesied has arrived. The Spirit is no longer given selectively to kings, priests, and prophets — he is poured out on all flesh, on sons and daughters, on young and old, on servants. The democratization of the Spirit is the defining mark of the new covenant age. “In the last days, God says, I will pour out my Spirit on all people.” — Acts 2:17 (NIV)

Question 13

What was the Areopagus, and why was it the most challenging venue Paul ever preached in?

Accepted Answer

The Areopagus (Mars Hill) was Athens’ ancient council of philosophers and civic leaders — the intellectual center of the Greco-Roman world. Paul was not invited to preach; he was summoned to explain his “foreign ideas.” His audience included Epicurean and Stoic philosophers who had no knowledge of the Hebrew Scriptures and no framework for a bodily resurrection. The Epicureans believed the gods were indifferent to human affairs and that death was simply the end. The Stoics believed in an impersonal divine reason (logos) that permeated the universe. Paul had to build a theological bridge from their worldview to the gospel without the scaffolding of Jewish Scripture. He did this by starting with creation (God made the world), moving to providence (God governs history), and arriving at the resurrection (God raised Jesus as judge). It is the most sophisticated piece of apologetics in the New Testament. “For in him we live and move and have our being.” — Acts 17:28 (NIV)

Question 14

Paul used Greek poetry to make his point. Is it legitimate to use secular culture, art, or philosophy to share the gospel?

Accepted Answer

Paul quotes two Greek poets — Epimenides (“in him we live and move and have our being”) and Aratus (“we are his offspring”) — not to endorse their theology but to find points of genuine contact between the gospel and his audience’s existing beliefs. This is not compromise; it is translation. The principle is this: all truth is God’s truth. When a secular philosopher, novelist, or filmmaker captures something genuinely true about the human condition — longing, guilt, love, death, meaning — that truth can serve as a bridge to the gospel. Paul’s approach legitimizes engaging seriously with culture rather than retreating from it. The test is not whether the source is secular but whether the truth being cited is genuinely true and whether it points toward rather than away from Christ. “For we are indeed his offspring.” — Acts 17:28 (NIV)

Question 15

The Areopagus sermon ended with mixed results — some mocked, some believed, some wanted to hear more. Is this a model for success or failure?

Accepted Answer

By any modern metrics of ministry success, the Areopagus sermon was a mixed result: a few converts, no church planted, no follow-up mentioned. Yet Luke includes it as a model of apostolic witness, not a cautionary tale. This tells us something important about how the New Testament measures success. The apostolic model is faithful proclamation, not guaranteed results. Paul did not adjust his message when the crowd mocked the resurrection — he did not soften it or remove the offense. The three responses (mockery, openness, belief) are the three responses the gospel always produces. Luke’s point is not that Paul failed in Athens but that the gospel was faithfully proclaimed in the intellectual capital of the ancient world. The seed was planted; the harvest belongs to God. “When they heard about the resurrection of the dead, some of them sneered, but others said, “We want to hear you again on this subject.”” — Acts 17:32 (NIV)

Question 16

Acts 1:8 is often called the “outline verse” of the entire book. How does the rest of Acts fulfill this single sentence?

Accepted Answer

Jesus’ final commission — “You will be my witnesses in Jerusalem, and in all Judea and Samaria, and to the ends of the earth” — functions as the structural outline of Acts. Chapters 1–7 cover Jerusalem; chapters 8–12 cover Judea and Samaria; chapters 13–28 trace the gospel’s advance to the ends of the earth, culminating in Rome. This is not accidental literary structure — it is theological architecture. Luke is showing that the church’s expansion is not the result of human planning or ambition but the fulfillment of a divine commission. Every missionary journey, every persecution, every shipwreck, every imprisonment advances the gospel according to the pattern Jesus established before his ascension. The book of Acts is the story of Acts 1:8 being fulfilled. “You will be my witnesses in Jerusalem, and in all Judea and Samaria, and to the ends of the earth.” — Acts 1:8 (NIV)

Question 17

The early church held everything in common (Acts 2:44–45; 4:32–35). Is this a model for Christian community today?

Accepted Answer

The Jerusalem community’s practice of sharing possessions is one of the most discussed and debated passages in Acts. It is important to note that this was voluntary, not compulsory (Acts 5:4 makes clear that Ananias was not required to sell his property). It was also a response to a specific historical situation: many pilgrims had stayed in Jerusalem after Pentecost and needed support. The principle behind the practice — that the community of believers takes responsibility for one another’s needs — is clearly normative (see 2 Corinthians 8–9; Galatians 6:2). The specific form (communal property) is not mandated. What is mandated is a generosity so radical that “there were no needy persons among them” (Acts 4:34). This echoes Deuteronomy 15:4: “there need be no poor people among you.” The church is called to embody the economic ethics of the kingdom. “All the believers were one in heart and mind.” — Acts 4:32 (NIV)

Question 18

Stephen’s speech in Acts 7 is the longest speech in the book. Why does Luke give so much space to a speech that ends in martyrdom?

Accepted Answer

Stephen’s speech is a comprehensive retelling of Israel’s history, culminating in the accusation that Israel has always resisted the Holy Spirit and killed the prophets. It is not a defense speech — it is a prosecution. Stephen is not trying to escape; he is delivering a verdict. Luke gives Stephen’s speech such prominence because it is the theological turning point of Acts. After Stephen’s martyrdom, the Jerusalem church is scattered (8:1), and the gospel begins its expansion to Samaria and beyond. Stephen’s death is not a setback — it is the catalyst for the mission. Luke also introduces Saul at this moment (7:58; 8:1), planting the seed for the most dramatic conversion in the book. Stephen’s martyrdom is the hinge on which the entire narrative turns. “Lord, do not hold this sin against them.” — Acts 7:60 (NIV)

Question 19

How did the church at Antioch become the launching pad for world mission, and what made it different from Jerusalem?

Accepted Answer

Antioch was the third-largest city in the Roman Empire and the first truly multiethnic church. It was here that believers were first called Christians (Acts 11:26) — a name given by outsiders who noticed that this community was defined by its allegiance to Christ rather than by ethnicity or social class. The Antioch church was also the first to commission and fund missionaries (Acts 13:1–3). The Jerusalem church had been the center of the movement, but Antioch became the base for the Gentile mission. This shift is significant: the gospel was no longer moving from Jerusalem outward as a Jewish movement but from Antioch outward as a universal one. The Holy Spirit’s instruction — “Set apart for me Barnabas and Saul for the work to which I have called them” — marks the beginning of intentional cross-cultural mission. “Set apart for me Barnabas and Saul for the work to which I have called them.” — Acts 13:2 (NIV)

Question 20

Paul and Barnabas had a sharp disagreement over John Mark (Acts 15:36–41). How should Christians handle conflict within ministry partnerships?

Accepted Answer

The conflict between Paul and Barnabas is one of the most honest moments in Acts. Luke does not sanitize it: “They had such a sharp disagreement that they parted company” (15:39). Both men had legitimate points. Barnabas wanted to give John Mark a second chance; Paul was unwilling to risk the mission on someone who had previously deserted them (13:13). The outcome is instructive: the disagreement resulted in two missionary teams instead of one, doubling the reach of the mission. God’s sovereignty worked through human conflict. The story also has a redemptive arc: Paul later writes warmly of Mark (“Get Mark and bring him with you, because he is helpful to me in my ministry” — 2 Timothy 4:11), suggesting that reconciliation eventually occurred. The lesson is not that conflict is good but that God can use even our failures and disagreements to advance his purposes. “They had such a sharp disagreement that they parted company.” — Acts 15:39 (NIV)

Question 21

Paul’s sermon in Pisidian Antioch (Acts 13:16–41) is his first recorded sermon. How does it compare to Peter’s Pentecost sermon, and what does the difference reveal?

Accepted Answer

Both sermons follow the same basic structure: a retelling of Israel’s history, a proclamation of Jesus’ death and resurrection, and a call to repentance. But the audiences differ, and the emphases shift accordingly. Peter speaks to Jerusalem Jews who witnessed the crucifixion; Paul speaks to diaspora Jews and God-fearers in Asia Minor who know the Scriptures but are more distant from the events. Peter’s sermon emphasizes the guilt of Jerusalem (“you, with the help of wicked men, put him to death” — 2:23) and calls for repentance. Paul’s sermon emphasizes the fulfillment of Scripture and the offer of forgiveness: “through him everyone who believes is set free from every sin” (13:39). Both sermons are anchored in the resurrection, but Paul’s is more explicitly forensic — it uses the language of justification that will dominate his letters. Acts 13 is the bridge between the Gospels and the Pauline epistles. “Through him everyone who believes is set free from every sin.” — Acts 13:39 (NIV)
