Through the Bible with Joseph

Acts 18

God at Work Through Ordinary People

About Acts 18

Paul brings the good news about Jesus to Corinth, where he faces both open hearts and strong pushback. God encourages him to stay, while the chapter also shows how faithful friends and patient teaching help the church grow.

Setting the Scene
Luke wrote Acts to show how the message of Jesus spread through the work of the Holy Spirit. This chapter follows Paul’s visit to Athens during his second major journey to share the gospel. Corinth was a busy center of trade in southern Greece, where people from many places lived and worked.

Walking Through Acts 18

Working Together and Speaking Clearly (Acts 18:1-6)

1 After this Paul departed from Athens and went to Corinth. 2 There he found a Jew named Aquila, a native of Pontus, who had recently come from Italy with his wife Priscilla, because Claudius had ordered all the Jews to depart from Rome. Paul approached them, 3 and because he worked at the same trade, he stayed with them and worked with them (for they were tentmakers by trade). 4 He addressed both Jews and Greeks in the synagogue every Sabbath, attempting to persuade them. 5 Now when Silas and Timothy arrived from Macedonia, Paul became wholly absorbed with proclaiming the word, testifying to the Jews that Jesus was the Christ. 6 When they opposed him and reviled him, he protested by shaking out his clothes and said to them, “Your blood be on your own heads! I am guiltless! From now on I will go to the Gentiles!”Acts 18:1-6 · NET Bible

In Corinth, Paul meets Aquila and Priscilla, a married couple who had left Italy because Emperor Claudius ordered the Jews to leave Rome. They share Paul’s trade of tentmaking, so he stays and works with them. Each Sabbath, Paul speaks in the synagogue, the Jewish place of worship, seeking to persuade Jews and Greeks. When Silas and Timothy arrive, Paul gives his time fully to preaching that Jesus is the Christ, God’s promised King. Some strongly oppose him and speak against his message. Paul shakes out his clothes as a sign that they are responsible for rejecting what they have heard. His decision to turn to the Gentiles, people who are not Jewish, concerns this local setting; he will still speak in other synagogues. I notice how ordinary work and faithful witness belong together here. God’s work grows through both shared labor and clear words about Jesus.

A Reason to Keep Speaking (Acts 18:7-11)

7 Then Paul left the synagogue and went to the house of a person named Titius Justus, a Gentile who worshiped God, whose house was next door to the synagogue. 8 Crispus, the president of the synagogue, believed in the Lord together with his entire household, and many of the Corinthians who heard about it believed and were baptized. 9 The Lord said to Paul by a vision in the night, “Do not be afraid, but speak and do not be silent 10 because I am with you, and no one will assault you to harm you because I have many people in this city.” 11 So he stayed there a year and six months, teaching the word of God among them.Acts 18:7-11 · NET Bible

Paul leaves the synagogue and begins teaching next door in the home of Titius Justus, a man who worships God. Crispus, the synagogue leader, believes in the Lord with his household. Many other Corinthians also hear, believe, and are baptized. Opposition has not stopped the message from reaching people. Then the Lord speaks to Paul in a night vision. Jesus tells him not to fear or stop speaking. He promises his presence and protection, explaining that many people in the city belong to him. Paul stays for a year and a half, teaching God’s word. These words are a specific promise to Paul in Corinth, not a promise that every Christian will escape harm. Still, they show us the Lord’s loving care for his servant. I find it comforting that faithful service does not mean we never need courage renewed.

The Case That Did Not Succeed (Acts 18:12-17)

12 Now while Gallio was proconsul of Achaia, the Jews attacked Paul together and brought him before the judgment seat, 13 saying, “This man is persuading people to worship God in a way contrary to the law!” 14 But just as Paul was about to speak, Gallio said to the Jews, “If it were a matter of some crime or serious piece of villainy, I would have been justified in accepting the complaint of you Jews, 15 but since it concerns points of disagreement about words and names and your own law, settle it yourselves. I will not be a judge of these things!” 16 Then he had them forced away from the judgment seat. 17 So they all seized Sosthenes, the president of the synagogue, and began to beat him in front of the judgment seat. Yet none of these things were of any concern to Gallio.Acts 18:12-17 · NET Bible

When Gallio becomes the Roman governor of Achaia, Paul’s opponents bring him before the judgment seat. They claim he is leading people to worship God against the law. Before Paul can defend himself, Gallio refuses to hear the case. He sees it as a dispute about Jewish teaching, names, and law, rather than a crime that needs Roman judgment. He sends the accusers away. Then Sosthenes, the synagogue leader, is beaten in front of the judgment seat, and Gallio does nothing. Luke does not clearly identify who carries out the beating or explain their motive. We should not add details he leaves out. Gallio’s lack of concern is not held up as kindness or justice. Yet the effort to use Roman power against Paul fails. In the flow of the chapter, we see the Lord’s promise of protection holding firm despite strong opposition.

Travel Plans Held Before God (Acts 18:18-23)

18 Paul, after staying many more days in Corinth, said farewell to the brothers and sailed away to Syria accompanied by Priscilla and Aquila. He had his hair cut off at Cenchrea because he had made a vow. 19 When they reached Ephesus, Paul left Priscilla and Aquila behind there, but he himself went into the synagogue and addressed the Jews. 20 When they asked him to stay longer, he would not consent, 21 but said farewell to them and added, “I will come back to you again if God wills.” Then he set sail from Ephesus, 22 and when he arrived at Caesarea, he went up and greeted the church at Jerusalem and then went down to Antioch. 23 After he spent some time there, Paul left and went through the region of Galatia and Phrygia, strengthening all the disciples.Acts 18:18-23 · NET Bible

After staying longer in Corinth, Paul sails toward Syria with Priscilla and Aquila. Before leaving the region, he has his hair cut at Cenchreae because of a vow. Luke gives no further details about that promise to God, so we should not build a story around it. At Ephesus, Paul speaks with the Jews in the synagogue. They ask him to stay, but he declines, leaving open a return if God wills. Priscilla and Aquila remain there. Paul lands at Caesarea and goes up to greet the church, most likely in Jerusalem, before returning to Antioch. This brings his second major journey to a close. After some time, he travels again through Galatia and Phrygia, strengthening the disciples. Paul cares about more than reaching new places. Believers also need steady help to grow. His plans show purpose, but they remain open to God’s direction.

A Gifted Teacher Who Could Still Learn (Acts 18:24-28)

24 Now a Jew named Apollos, a native of Alexandria, arrived in Ephesus. He was an eloquent speaker, well-versed in the scriptures. 25 He had been instructed in the way of the Lord, and with great enthusiasm he spoke and taught accurately the facts about Jesus, although he knew only the baptism of John. 26 He began to speak out fearlessly in the synagogue, but when Priscilla and Aquila heard him, they took him aside and explained the way of God to him more accurately. 27 When Apollos wanted to cross over to Achaia, the brothers encouraged him and wrote to the disciples to welcome him. When he arrived, he assisted greatly those who had believed by grace, 28 for he refuted the Jews vigorously in public debate, demonstrating from the scriptures that the Christ was Jesus.Acts 18:24-28 · NET Bible

Apollos arrives in Ephesus from Alexandria, a major city in Egypt. He is a gifted speaker who knows the Scriptures well. He teaches about Jesus accurately and with great energy, but his knowledge is not complete. He knows only John’s baptism, which called people to turn from sin and prepared them for Jesus. Luke does not list every gap in his understanding. Priscilla and Aquila hear him, take him aside, and explain God’s way more fully. They do not treat his gifts as useless because he still needs help. When Apollos wants to go to Achaia, the believers encourage him and send a letter asking the disciples there to welcome him. He becomes a great help to those who have believed through grace, God’s freely given kindness. Using the Scriptures, he shows publicly that Jesus is the Christ. God grows his church through gifted teaching and humble learning.

Key Words
  • Grace — God’s freely given kindness, through which people come to believe and receive help.
  • Strengthening — Helping believers become steadier in their trust and understanding.
How It Fits the Whole Bible
Acts 18 shows the good news about Jesus taking root among both Jews and Gentiles. The promised King of Israel is gathering people from many nations into one family. Christ builds his church through preaching, ordinary work, friendship, and careful teaching, with no single worker doing everything.
Living It Out
Make room for both giving help and receiving it as you grow in faith. When someone needs correction, follow the care shown by Priscilla and Aquila rather than using truth to embarrass them. Value the quiet work of strengthening believers as well as the work of reaching new people.
Something to Think About

How does the way Priscilla and Aquila helped Apollos shape the way you give or receive correction?

A Closing Prayer

Father, thank you for staying faithful when your people face fear and opposition. Give us courage to speak about Jesus and humility to keep learning. Help us strengthen others with truth and love. Amen.
