Acts 18
Paul arrives in Corinth. The city is a crossroads of empire - wealthy, cosmopolitan, morally fractured. It is not a place where the gospel would naturally take root. But Paul comes not with rhetoric or silver, but with his hands. He learns tentmaking from Aquila and Priscilla, two Jewish believers he finds in the city. He works with them; he reasons in the synagogue on Sabbath. Opposition comes. The Jewish leaders reject him. But the Lord comes to Paul in a vision and says something that shapes the rest of his ministry: "I am with thee, and no man shall set on thee to hurt thee: for I have much people in this city." In the most unlikely place, God has a people.
What unfolds is not a triumph of persuasion but a slow, faithful work of presence. Paul stays for eighteen months. A church grows. Meanwhile, an eloquent man named Apollos - burning with the Spirit, skilled in Scripture, but incomplete in his understanding - arrives in Ephesus. And it is a woman, Priscilla, alongside her husband Aquila, who draws him aside and teaches him more fully. The chapter shows us the shape of apostolic work: partnership, patient labor, the courage to stay when the message is rejected, and the humility to teach and be taught.

People in this chapter
A Roman citizen, a Pharisee trained under Gamaliel, and a hunter of the early church. Confronted by the risen Jesus on the road to Damascus, he became the missionary who carried the gospel across the Mediterranean and wrote thirteen of the New Testament’s twenty-seven books.
Tentmaker by trade. Expelled from Rome with all Jews under Emperor Claudius (c. AD 49). Met Paul in Corinth, partnered with him in the trade and the gospel, then moved with Priscilla to Ephesus where they corrected Apollos in private. Hosted house-churches in both Ephesus and Rome.
Wife of Aquila. Often listed before her husband (an unusual ordering) - likely indicating she was the more prominent teacher. Took Apollos aside in Ephesus and "expounded unto him the way of God more perfectly." Hosted churches with Aquila in Corinth, Ephesus, and Rome.
A learned man "fervent in the spirit" who arrived in Ephesus knowing only the baptism of John. Priscilla and Aquila instructed him; he then went to Achaia and "mightily convinced the Jews… that Jesus was Christ." Some at Corinth followed him to the point of party-spirit, which Paul rebuked.
Acts 18:1-4Partners in Tentmaking
1After these things Paul departed from Athens, and came to Corinth; 2And found a certain Jew named Aquila, born in Pontus, lately come from Italy, with his wife Priscilla; (because that Claudius had commanded all Jews to depart from Rome:) and came unto them. 3And because he was of the same craft, he abode with them, and wrought: for by their occupation they were tentmakers. 4And he reasoned in the synagogue every sabbath, and persuaded the Jews and the Greeks.
Paul does not arrive as an itinerant preacher with nothing. He arrives with a trade. He finds work alongside Aquila and Priscilla, fellow believers who have been scattered by Rome's expulsion of Jews under Claudius. They share a craft. The word here - "abode with them and wrought" - is the same word Paul uses elsewhere for working together in mission (2 Corinthians 6:1; 1 Thessalonians 3:2)3. The Greek is synergos - co-workers. The tentmaking is not separate from the gospel work. It is the gospel work.
Every Sabbath, Paul goes to the synagogue and reasons - dialogomai, literally "to dialogue." He does not sermonize; he engages. He listens and speaks. He persuades through conversation, not force. This is his pattern in every city: he meets people where they gather, and he speaks to them with respect, even when they will reject him.
Acts 18:5-8Rejected by the Synagogue
5And when Silas and Timotheus were come from Macedonia, Paul was pressed in the spirit, and testified to the Jews that Jesus was Christ. 6And when they opposed themselves, and blasphemed, he shook his raiment, and said unto them, Your blood be upon your own heads; I am clean: from henceforth I will go unto the Gentiles. 7And he departed thence, and entered into a certain man's house, named Titius Justus, one that worshipped God, and whose house was hard by the synagogue. 8And Crispus, the chief of the synagogue, believed on the Lord with all his house: and many of the Corinthians hearing, believed, and were baptized.
When Silas and Timothy arrive with news from Macedonia, Paul is "pressed in the spirit" - suntecho, literally "held together" or "constrained." The pressure is not external; it is internal. He is gripped by the Spirit's urgency. He testifies intensely that Jesus is the Messiah. He is not cautious. He is not hedging. He is fully committed.
The Jews oppose and blaspheme. They do not simply disagree. They speak against Jesus. They curse the name of Christ. And Paul - in that moment - makes a decisive break. He does not retreat into softness or compromise.
Paul shakes out his garments - a gesture of judgment, the ancient equivalent of wiping dust off and walking away. He quotes the language of judgment: "Your blood be upon your own heads." This is not cruelty. This is the necessary word a prophet speaks when his people reject mercy. Paul is saying: I have testified to you about Jesus. You have rejected it. You have chosen. The consequences of that choice are yours. I release the burden of your rejection. And now I turn to those who will listen.
Acts 18:9-11The Lord's Vision: "I Have Much People Here"
9Then spake the Lord to Paul in the night by a vision, Be not afraid, but speak, and hold not thy peace 10For I am with thee, and no man shall set on thee to hurt thee: for I have much people in this city. 11And he continued there a year and six months, teaching the word of God among them.
Paul has just experienced the severest rejection yet. He has drawn a line. He has turned away. In the aftermath, fear comes. The Lord meets him in a vision and addresses it directly: "Be not afraid." Fear is not sin. But it is not the final word. The reason for courage is not that Corinth is safer than Paul thought. It is that God has promised His presence.
"For I have much people in this city." This is extraordinary. Corinth is hostile to the gospel. The synagogue has rejected Paul. The culture is pagan, wealthy, morally fractured. Yet the Lord says: I have a people here. Not a small handful. Many. They are not yet visible. They have not yet believed. But they are already the Lord's. They are predestined to hear, to respond, to become His church. Paul's work is not to create a people for God. It is to gather a people God has already chosen.
Acts 18:12-17Gallio Refuses to Judge
12And when Gallio was the deputy of Achaia, the Jews made insurrection with one accord against Paul, and brought him to the judgment seat, 13Saying, This fellow persuadeth men to worship God contrary to the law. 14And when Paul was now about to open his mouth, Gallio said unto the Jews, If it were a matter of wrong or wicked lewdness, O ye Jews, reason would that I should bear with you: 15But if it be a question of words and names, and of your law, look ye to it; for I will be no judge of such matters. 16And he drave them from the judgment seat. 17Then all the Greeks took Sosthenes, the chief of the synagogue, and beat him before the judgment seat. And Gallio cared for none of those things.
Gallio is the Roman deputy of Achaia. The Jews have grown bold enough to drag Paul before the magistrate. They accuse him of persuading men to worship contrary to the law. But Gallio refuses the case. He says: "If it were a matter of wrong or wicked lewdness, I would hear you. But if it is a question of your law, look to it yourselves." Gallio treats Christianity as an internal Jewish dispute, not a crime against Rome. He will not judge it1. He drives them from the court.
What happens next is striking. The Greeks (who are not even party to the dispute) beat Sosthenes, the chief of the synagogue, right in front of the judgment seat. Why? Perhaps they are punishing him for bringing a frivolous case. Perhaps they are expressing contempt for the Jews. Perhaps they sense that the gospel is beginning to shift the power dynamics in the city2. And Gallio? He cares for none of it. His indifference is the turning point. Paul is protected by Roman law. The opposition has overreached. The synagogue's authority has been undercut.
Acts 18:18-21Through Ephesus to Antioch
18And Paul after this tarried there yet a good while, and then took his leave of the brethren, and sailed into Syria, and with him Priscilla and Aquila: having shorn his head in Cenchrea: for he had a vow. 19And he came to Ephesus, and left them there: but he himself entered into the synagogue, and reasoned with the Jews. 20When they desired him to tarry longer time with them, he consented not; 21But bade them farewell, saying, I must by all means keep this feast that cometh in Jerusalem: but I will return unto you, if God will. And he sailed from Ephesus.
Paul has stayed for eighteen months. He leaves with Priscilla and Aquila. The mention of the vow - shearing his head in Cenchrea - suggests a Nazirite vow, an act of dedication and prayer. He is carrying something sacred. He is carrying the church of Corinth, bound in covenant, to Jerusalem.
At Ephesus, Paul pauses. He reasons in the synagogue. The people ask him to stay longer. But he declines. He says: "I must by all means keep this feast that cometh in Jerusalem." Jerusalem is calling him. The church there is calling him. Yet he adds: "but I will return unto you, if God will." It is not goodbye. It is a promise held loosely - held with faith, not with human control.
Acts 18:24-26An Eloquent Man, Incomplete
24And a certain Jew named Apollos, born at Alexandria, an eloquent man, and mighty in the scriptures, came to Ephesus. 25This man was instructed in the way of the Lord; and being fervent in the spirit, he spake and taught diligently the things of the Lord, knowing only the baptism of John. 26And he began to speak boldly in the synagogue: whom when Aquila and Priscilla had heard, they took him unto them, and expounded unto him the way of God more perfectly
Apollos is "mighty in the scriptures" - dunathos, powerful, competent, skilled4. He knows the Old Testament. He understands the line of prophecy about the Messiah. He is not ignorant or lazy. He is genuinely learned.
Apollos knows only John's baptism. This is a crucial gap. John baptized unto repentance. But John also pointed beyond himself to "one mightier than I." Apollos has not yet encountered the fullness of Christ - not the resurrection, not the gift of the Holy Spirit at Pentecost, not the inaugurated kingdom. He is burning, but incomplete.
Acts 18:27-28The Power of Patient Teaching
27And when he was disposed to pass into Achaia, the brethren wrote, exhorting the disciples to receive him: who, when he was come, helped them much which had believed through grace; 28For he mightily convinced the Jews, and that publicly, showing by the scriptures that Jesus was Christ.
Priscilla and Aquila "expounded unto him the way of God more perfectly." The Greek word is akribos - more accurately, more carefully, more thoroughly. They do not shame him. They do not challenge his competence. They simply teach him with precision. And it works. Apollos moves from being a burning talent to being a mature teacher.
Apollos becomes such a powerful teacher that the Ephesian church writes letters commending him. He goes to Corinth - the very city where Paul had just planted the church. The two greatest preachers of the apostolic age nearly miss each other entirely. And later, Paul will write to Corinth addressing divisions created by people claiming loyalty to Apollos or to himself (1 Corinthians 1:12). But there is no rivalry between them. Apollos has been taught well. He has been set free from his incomplete knowledge.
