Overview
Acts 18 records a pivotal moment in Paul’s second missionary journey. After facing rejection in Athens, Paul travels to Corinth, one of the most morally corrupt cities in the Roman Empire, where he continues to preach the gospel with boldness. He meets Aquila and Priscilla, fellow tentmakers and Jewish Christians, who become significant ministry partners. Paul preaches in the synagogue, faces opposition, and then turns to the Gentiles, finding fruit in unexpected places.
The Lord encourages Paul in a night vision to stay in Corinth despite persecution, assuring him of divine protection and the presence of many people in the city who belong to God. This chapter also introduces Gallio, the Roman proconsul, whose legal dismissal of the Jewish charges against Paul sets a precedent for the gospel’s legal protection under Roman law. Meanwhile, Apollos, a learned Jew, enters the narrative and begins preaching boldly but is discipled further in the truth by Aquila and Priscilla.
This chapter reveals the ongoing fulfillment of the Great Commission, the empowering presence of the Holy Spirit, and God’s sovereign guidance over the spread of the gospel. It emphasizes the necessity of faithful proclamation, Spirit-empowered discipleship, and the sustaining presence of Christ in mission.
Historical and Literary Context
Historical Background
- Corinth: A major city in Achaia (southern Greece), Corinth was known for its commerce, culture, and rampant immorality. The city housed the temple of Aphrodite and was a hub for both trade and vice. Preaching the gospel here was strategic yet difficult due to spiritual darkness.
- Aquila and Priscilla: Jewish believers expelled from Rome under Emperor Claudius (AD 49) because of disturbances related to “Chrestus” (likely Christ). This shows the spread and controversy of Christianity even in Rome.
- Gallio: The Roman proconsul of Achaia. His legal verdict dismissing the charges against Paul is historically important—it gave Christians some degree of legal tolerance under Roman rule at that time.
- Apollos: A Jew from Alexandria, eloquent and mighty in Scripture. His partial understanding (knowing only the baptism of John) underscores the ongoing need for accurate, Spirit-led teaching within the early church.
Literary Structure and Style
Acts 18 continues Luke’s historical narrative style—recording specific names, places, and events with a clear theological purpose. Luke shows that the gospel is advancing by God’s providence, despite human opposition. The literary form includes travel details, speeches, personal interactions, and divine interventions. These serve to underscore the reliability of the account and the intentional fulfillment of God’s redemptive plan.

Verse-by-Verse Analysis: Acts 18 (Key Sections)
Verses 1–3 – Paul Meets Aquila and Priscilla
“After this, Paul left Athens and went to Corinth. There he met a Jew named Aquila… and his wife Priscilla… Paul went to see them, and because he was a tentmaker as they were, he stayed and worked with them.”
- Literal Meaning: Paul moves from intellectual, religious Athens to morally corrupt Corinth. God sovereignly orchestrates a meeting with Aquila and Priscilla—faithful Jews expelled from Rome who become vital ministry partners.
- Cross-Reference: Romans 16:3-5 commends them as coworkers who risked their lives for Paul.
- Application: God often uses unexpected circumstances (e.g., exile from Rome) for His greater redemptive plan. Bi-vocational ministry is valid and effective.
Verse 4–6 – Rejection by the Jews and Turning to the Gentiles
“Every Sabbath he reasoned in the synagogue… But when they opposed Paul and became abusive, he shook out his clothes in protest and said… ‘From now on I will go to the Gentiles.’”
- Literal Meaning: Paul, as was his pattern, begins in the synagogue. Rejection by the Jewish leaders leads him to turn to the Gentiles.
- Doctrinal Insight: This continues the fulfillment of Acts 1:8—Jerusalem, Judea, Samaria, and to the ends of the earth. God’s plan includes all nations.
- Application: Ministry requires discernment on when to persist and when to redirect. Faithfulness doesn’t always mean fruitfulness among the same people.
Verses 7–8 – Salvation in Corinth
“Then Paul left the synagogue and went next door to the house of Titius Justus… Crispus, the synagogue leader, and his entire household believed in the Lord…”
- Cross-Reference: 1 Corinthians 1:14 mentions Paul baptizing Crispus.
- Doctrinal Insight: Even in hostile environments, God brings about genuine conversions—including influential leaders.
- Application: No one is beyond God’s reach. Proximity to opposition (preaching next door) can still yield salvation.
Verses 9–11 – The Lord’s Encouragement to Paul
“‘Do not be afraid; keep on speaking… I am with you, and no one is going to attack and harm you, because I have many people in this city.’”
- Literal Meaning: The risen Jesus appears to Paul in a vision, encouraging him to stay and minister boldly.
- Cross-Reference: Matthew 28:20 – “I am with you always.”
- Doctrinal Insight: Christ actively leads and sustains His servants. Evangelistic success is grounded in divine sovereignty.
- Application: When discouraged, remember Christ’s presence and the hidden work of God in people’s hearts.
Verses 12–17 – Gallio’s Judgment
“Gallio… drove them off. Then the crowd turned on Sosthenes the synagogue leader and beat him…”
- Historical Insight: Gallio‘s refusal to judge religious disputes set a legal precedent that allowed Christianity a degree of protection under Roman law.
- Doctrinal Insight: God governs even pagan rulers to protect His church (Proverbs 21:1).
- Application: Trust God’s providence in political and legal structures. Even apparent secular apathy can shield gospel advancement.
Verses 18–23 – Paul’s Return and Strengthening the Churches
“Paul stayed on… then he set sail for Syria… having his hair cut off… he went through Galatia and Phrygia, strengthening all the disciples.”
- Literal Meaning: Paul wraps up his second missionary journey and begins a third, with a brief vow likely connected to a Nazarite vow (Num. 6:18).
- Application: Ministry involves both expansion (missionary journeys) and strengthening the established (discipleship and revisits).
Verses 24–28 – Apollos Begins His Ministry
“He had been instructed in the way of the Lord… He began to speak boldly… When Priscilla and Aquila heard him, they invited him to their home and explained to him the way of God more adequately.”
- Doctrinal Insight: Apollos knew truth but needed fuller teaching. Discipleship is essential even for the gifted.
- Cross-Reference: 1 Corinthians 3:5-6 – Paul and Apollos are both servants used by God.
- Application: Leaders must be teachable. Churches must ensure accurate doctrine is passed down and corrected lovingly.
Theological Implications and Connection to Jesus Christ
1. Christ’s Active Presence and Leadership
Jesus Himself appears to Paul (vv. 9-10) and promises His abiding presence and divine protection. This echoes His promise in the Great Commission (Matthew 28:20) and reflects that He is the living Head of the Church (Colossians 1:18).
2. Christ as Fulfillment of the Scriptures
Apollos powerfully refuted the Jews, proving that Jesus was the Messiah (v. 28). This demonstrates that all Scripture points to Jesus (Luke 24:27, John 5:39). The gospel is not a new message but the fulfillment of God’s promises.
3. Christ Unites Jew and Gentile
Paul’s turn from the Jews to the Gentiles again shows that salvation is in Christ alone and offered to all. This aligns with Ephesians 2:14-16—Jesus breaks down the dividing wall and makes one new humanity through His cross.
Connection to God the Father
1. God’s Sovereign Hand in Mission
The Father’s providence is seen in every detail—from Paul meeting Aquila and Priscilla, to Gallio‘s judgment, to Apollos’ discipleship. Acts 18 reflects Ephesians 1:11—God works all things according to the counsel of His will.
2. The Father Calls and Owns His People
“I have many people in this city” (v. 10) – This is a statement of divine election. Before conversion, they already belonged to God. This aligns with John 6:37 – “All those the Father gives me will come to me.”
3. The Father Sends the Son and the Spirit
Behind every missionary effort and every gospel advance is the will of the Father. As seen throughout Acts, the Father is the originator of salvation’s plan, sending both His Son (John 3:16) and the Holy Spirit (Acts 2:33).
Summary
Acts 18 shows a sovereign God orchestrating gospel expansion through faithful witnesses like Paul, Aquila, Priscilla, and Apollos. Jesus Christ is central—encouraging His servants, fulfilling prophecy, and building His Church. The Father is revealed as the One who calls, directs, and preserves His people for His glory.
This chapter reinforces the foundational truths of Scripture:
- God reigns.
- Christ is central.
- The Spirit empowers.
- The Church advances.
Connection to the Holy Spirit in Acts 18
Though Acts 18 does not explicitly mention the Holy Spirit by name as often as other chapters, His work is evident and essential throughout:
1. Spirit-Led Relationships and Ministry Opportunities
- The Spirit sovereignly orchestrates Paul’s encounter with Aquila and Priscilla (v. 2), two faithful believers prepared for long-term ministry impact. This reflects the Spirit’s work in uniting the Body for mutual encouragement and mission (1 Corinthians 12:7-11).
2. Empowerment for Bold Preaching
- Paul continues to preach in difficult contexts (v. 5), and Apollos speaks boldly in the synagogue (v. 26). Boldness in witness is a repeated fruit of the Holy Spirit in Acts (cf. Acts 4:31; 1 Thessalonians 1:5).
3. Guidance through Divine Encouragement
- Jesus‘ vision to Paul (vv. 9–10) reflects how the Spirit comforts and encourages believers in times of fear and opposition (John 14:16-17; Romans 8:16). Though Christ speaks directly, the Spirit is the means by which the presence of Christ is experienced.
4. Equipping the Church through Discipleship
- Aquila and Priscilla’s Spirit-led discipleship of Apollos (v. 26) reflects the Spirit’s role in maturing believers and protecting doctrinal integrity (John 16:13; Ephesians 4:11-13).
Sermon Outline and Flow: “Faithfulness in the Midst of Opposition” (Acts 18)
Sermon Title: Faithfulness in the Midst of Opposition
Text: Acts 18:1-28
Main Idea: God sovereignly advances His mission through faithful servants empowered by His presence, even amid opposition.
I. God Places the Right People in the Right Places (vv. 1–4)
Paul meets Aquila and Priscilla and begins ministry in Corinth.
- Truth: God providentially connects His servants for gospel work.
- Application: Trust God’s placement in your life—He is preparing people to walk with you.
- Illustration: Like a relay race, God passes the baton through different runners at key times to accomplish His plan.
II. When Opposition Rises, God’s Mission Does Not Stop (vv. 5–8)
Paul faces rejection but preaches next door, and many believe.
- Truth: Rejection is not failure—sometimes it’s redirection.
- Application: Don’t stop sharing the gospel because of opposition; God’s Word will not return void (Isaiah 55:11).
- Illustration: A farmer doesn’t give up when some seeds fall on rocky soil; he keeps sowing, knowing some will bear fruit.
III. Christ Encourages His Servants in Their Weakest Moments (vv. 9–11)
Jesus appears to Paul in a vision: “Do not be afraid.”
- Truth: Jesus gives His presence and peace when we are weary.
- Application: In your ministry or personal fear, remember you are not alone—Christ is with you.
- Personal Story: Share a moment of personal discouragement when God’s Word or a fellow believer encouraged you to press on.
IV. God Uses Even Unbelievers to Protect His Church (vv. 12–17)
Gallio dismisses the case against Paul.
- Truth: God can use secular authorities to preserve gospel freedom.
- Application: Pray for and engage leaders respectfully, knowing God is ultimately in control (1 Timothy 2:1-2).
- Analogy: Like a chess grandmaster, God positions even “non-believing pieces” for the sake of His plan.

Apollos is taught more accurately and becomes a powerful preacher.
- Truth: The Church must be committed to truth and discipleship.
- Application: Be humble like Apollos—always growing, and be intentional like Aquila and Priscilla—always teaching.
- Modern Example: A young believer grows through a small group or mentoring relationship and becomes a future church leader.
Conclusion:
- Call to Action:
“Be faithful where God has placed you. You may be the link that launches a future Apollos, or the voice that reaches a hidden Crispus.”
Modern-Day Illustrations and Examples
1. Tentmaking and Bi-Vocational Ministry
- Like Paul, many pastors and missionaries today work part-time jobs to support their calling. God uses every skill for ministry.
- Example: A school teacher who mentors students in Scripture during lunch breaks or Bible club.
2. Persecution and Protection
- In places where Christianity is opposed, government policies or even court decisions sometimes protect believers unexpectedly.
- Example: A pastor in Southeast Asia whose case is dropped due to legal technicalities, allowing the church to grow more boldly.
3. Discipleship Legacy
- A Sunday School teacher investing in one child who later becomes a preacher.
- Example: A mentor leads a college student to Christ, who later plants a church in another country.
Application for Today’s Christian
Acts 18 provides a wealth of practical lessons for everyday Christian life. The experiences of Paul, Aquila and Priscilla, and Apollos illustrate how believers can live faithfully in various roles and circumstances.
1. Discipleship: Be Available to Grow and Help Others Grow
- Aquila and Priscilla exemplify a couple committed to mentoring others in the truth (v. 26). They gently guide Apollos into fuller knowledge of the gospel.
- Application:
- Join or lead a discipleship group.
- Invest time in a younger believer’s spiritual growth.
- Be humble and teachable like Apollos—willing to be corrected and equipped.
- Pastors and leaders should cultivate a mentoring culture within the church.
2. Stewardship: Use Your Vocation for God’s Mission
- Paul used his tentmaking trade to support himself and remain in ministry (v. 3).
- Application:
- Whether in business, teaching, or homemaking, see your profession as a mission field.
- Support kingdom work financially and with your skills.
- Churches should affirm and equip bi-vocational ministry where needed.
3. Faith and Endurance: Remain Faithful in Opposition
- Paul experienced rejection and intimidation, but Christ encouraged him to stay and preach (vv. 9–10).
- Application:
- When you’re discouraged or afraid, lean on God’s promises and presence.
- Stay rooted in Scripture and prayer, especially when facing hostility at work, school, or family settings.
- Encourage fellow believers with Scripture-based hope.
4. Bold Evangelism: Share the Gospel Wherever You Are
- Paul preached in the synagogue, a house next door, and throughout the city. Apollos debated powerfully in public.
- Application:
- Look for everyday opportunities to witness—over coffee, online, or during work breaks.
- Share your testimony as a bridge to the gospel.
- Don’t be afraid of rejection; your job is faithfulness.
Connection to God’s Love
Acts 18 showcases God’s deep love and providential care for His people and the lost:
1. God Seeks and Saves the Lost
- Jesus told Paul, “I have many people in this city” (v. 10), even before they believed. This reflects divine initiative in salvation.
- God was drawing people in Corinth—known for its sinfulness—to Himself for redemption.
- Truth: God’s love reaches even into the darkest places, pursuing sinners with grace and patience.
2. God Encourages and Strengthens His Servants
- Jesus personally encouraged Paul not to be afraid and to keep preaching.
- This reveals God’s fatherly compassion. He doesn’t just command—He walks with His people through the hardship.
- Truth: God loves His children enough to speak peace into their fear and assurance into their calling.
3. God Grows His Church Through Ordinary Faithfulness
- Aquila and Priscilla, everyday believers, quietly but powerfully shaped a future leader (Apollos).
- God’s love flows through the community of faith, forming a family that supports, corrects, and sends.
- Truth: God delights in using humble servants to carry His message of redemption forward.
Broader Biblical Themes
Acts 18 connects to major biblical themes that span from Genesis to Revelation, showing its place in God’s redemptive narrative:
1. Redemption – God Rescues and Transforms Lives
- Paul’s ministry in Corinth bears fruit even among unlikely people (e.g., Crispus, the synagogue leader).
- Apollos, once incomplete in his understanding, becomes a mighty gospel witness.
- Biblical Arc: From the fall (Genesis 3) to new creation (Revelation 21), God is redeeming broken people through Christ.
2. Covenant Faithfulness – God Keeps His Promises
- God’s covenant to bless all nations through Abraham (Genesis 12:3) is fulfilled as Gentiles come to faith in Christ.
- The church in Corinth becomes a living example of that promise.
- Biblical Arc: God’s covenant with Israel expands to include all who are in Christ (Romans 9:24-26; Galatians 3:7-9).
3. God’s Presence and Mission – “I Am With You”
- Jesus’ words to Paul in v. 10 echo God’s repeated promise throughout Scripture: “I will be with you” (Exodus 3:12; Joshua 1:5).
- This divine presence empowers God’s servants to fulfill their mission.
- Biblical Arc: From God walking with Adam, to the indwelling Spirit in believers today, to Revelation’s promise that God will dwell with His people forever (Revelation 21:3).
