Acts 18

Acts 18 — Do Not Be Afraid; Keep Speaking

Pray to Begin

Ask - for the Lord’s courage when fear says be silent: that you would keep speaking of Jesus as the Christ, trusting He has people even in hard cities.

Give thanks - for partners like Priscilla and Aquila, for open doors next door to closed synagogues, and for mentors who explain the way of God more accurately.

Yield - isolation that refuses teammates, pride that will not be taught, and despair that imagines no one in your city belongs to God.

Today’s Passage: Acts 18

Paul comes to Corinth, works as a tentmaker with Aquila and Priscilla, and reasons every Sabbath. When Silas and Timothy arrive, he devotes himself fully to the word. Opposition drives him next door to Titus Justus; Crispus believes; many Corinthians are baptized. In a night vision the Lord says: do not be afraid; keep speaking; I am with you; I have many people in this city. Paul stays eighteen months. Gallio dismisses Jewish charges. After a vow at Cenchrea, Paul sails with Priscilla and Aquila, leaves them at Ephesus, greets Jerusalem, returns to Antioch, and strengthens disciples through Galatia and Phrygia. Meanwhile Apollos arrives in Ephesus - eloquent, scriptural, knowing only John’s baptism - and Priscilla and Aquila take him aside. He then powerfully helps believers in Achaia. Full BSB below.

As you read, hold this: Corinth receives a long season of teaching, Gallio refuses to criminalize the gospel, and Apollos is taught the way more accurately.

Context The world of Acts 18

Corinth. Rebuilt Roman colony on the isthmus, two ports, wealth, vice, temples - a strategic and difficult field. Claudius’s expulsion of Jews from Rome (c. AD 49) brings Aquila and Priscilla. Gallio’s proconsulship (c. AD 51-52), confirmed by the Delphi inscription, anchors the chronology.

Tentmaking. Shared trade becomes shared mission. When Macedonian support arrives (cf. 2 Corinthians 11:9), Paul can give himself more fully to the word.

The bema. Gallio’s judgment seat is archaeologically visible in Corinth’s forum. His refusal to treat the gospel as a crime under Roman law gives the mission breathing room.

Apollos. Alexandrian Jew, eloquent, mighty in the Scriptures, instructed in the way, fervent, accurate about Jesus so far as he knows - yet only John’s baptism. Private correction by a couple, not public shaming, multiplies his usefulness in Achaia (and later Corinth; 1 Corinthians 1-3).

Acts 18:1-8 (BSB)

¹ After this, Paul left 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 leave Rome. Paul went to visit them, ³ and he stayed and worked with them because they were tentmakers by trade, just as he was. ⁴ Every Sabbath he reasoned in the synagogue, trying to persuade Jews and Greeks alike. ⁵ And when Silas and Timothy came down from Macedonia, Paul devoted himself fully to the word, testifying to the Jews that Jesus is the Christ. ⁶ But when they opposed and insulted him, he shook out his garments and told them, “Your blood be on your own heads! I am innocent of it. From now on I will go to the Gentiles.” ⁷ So Paul left the synagogue and went next door to the house of Titus Justus, a worshiper of God. ⁸ Crispus, the synagogue leader, and his whole household believed in the Lord. And many of the Corinthians who heard the message believed and were baptized.

Word study "Reasoned / persuaded" - dialegomai / peithō (Acts 18:4)

Greek: διαλέγομαι (dialegomai); πείθω (peithō, pay-THOH, G3982).

Paul reasons and seeks to persuade Jews and Greeks. The gospel is proclaimed with argument and appeal, not only announcement.

Word study "Devoted himself" - synechō (Acts 18:5)

Greek: συνέχω (synechō), pronounced soon-EKH-oh. Strong’s G4912.

When support arrives, Paul is occupied / held fast by the word - pressed into full proclamation. Mission sometimes means bi-vocational patience, then concentrated preaching when God provides.

From Mars Hill to a workshop. Exile under Claudius becomes providence: partners appear. Sabbath persuasion continues; then full devotion to the word. Opposition meets a prophetic gesture - shaking out garments - and a turn next door, not out of town. Crispus believes. Many Corinthians believe and are baptized. Rejection and harvest grow in the same street.

Acts 18:9-11 (BSB)

⁹ One night the Lord spoke to Paul in a vision: “Do not be afraid; keep on speaking; do not be silent. ¹⁰ For I am with you and no one will lay a hand on you, because I have many people in this city.” ¹¹ So Paul stayed for a year and a half, teaching the word of God among the Corinthians.

Word study "Do not be afraid" - mē phobou (Acts 18:9)

Greek: μὴ φοβοῦ (mē phobou). Strong’s G3361 + G5399.

The Lord’s first word to Paul in Corinth is courage. Fear is real after beatings and riots; presence is stronger: “I am with you.”

Night vision for a weary apostle. Mē phobou - do not fear. Keep speaking. Presence promised. Protection for this season. A hidden church already known to Christ: “I have many people in this city.” Paul stays eighteen months. Long obedience in a hard place is sometimes the miracle.

Acts 18:12-17 (BSB)

¹² While Gallio was proconsul of Achaia, the Jews coordinated an attack on Paul and brought him before the judgment seat. ¹³ “This man is persuading the people to worship God in ways contrary to the law,” they said. ¹⁴ But just as Paul was about to speak, Gallio told the Jews, “If this matter involved a wrongdoing or vicious crime, O Jews, it would be reasonable for me to hear your complaint. ¹⁵ But since it is a dispute about words and names and your own law, settle it yourselves. I refuse to be a judge of such things.” ¹⁶ And he drove them away from the judgment seat. ¹⁷ At this, the crowd seized Sosthenes the synagogue leader and beat him in front of the judgment seat. But none of this was of concern to Gallio.

Gallio will not criminalize an internal religious dispute. The gospel is not stamped illegal. The scene is messy - Sosthenes beaten, Gallio indifferent to the violence - yet the legal outcome protects the mission’s space in Achaia. God uses even a dismissive proconsul.

Acts 18:18-23 (BSB)

¹⁸ Paul remained in Corinth for quite some time before saying goodbye to the brothers. He had his head shaved in Cenchrea to keep a vow he had made, and then he sailed for Syria, accompanied by Priscilla and Aquila. ¹⁹ When they reached Ephesus, Paul left Priscilla and Aquila. He himself went into the synagogue there and reasoned with the Jews. ²⁰ When they asked him to stay for a while longer, he declined. ²¹ But as he left, he said, “I will come back to you if God is willing.” And he set sail from Ephesus. ²² When Paul had landed at Caesarea, he went up and greeted the church at Jerusalem. Then he went down to Antioch. ²³ After Paul had spent some time in Antioch, he traveled from place to place throughout the region of Galatia and Phrygia, strengthening all the disciples.

A vow at Cenchrea shows Paul free to practice Jewish devotion voluntarily without imposing it for salvation. Priscilla and Aquila stay in Ephesus - strategic planting. Paul greets Jerusalem, returns to Antioch, and begins the third journey by strengthening disciples. The word is not only advanced; it is confirmed.

Acts 18:24-28 (BSB)

²⁴ Meanwhile a Jew named Apollos, a native of Alexandria, came to Ephesus. He was an eloquent man, well versed in the Scriptures. ²⁵ He had been instructed in the way of the Lord and was fervent in spirit. He spoke and taught accurately about Jesus, though he knew only the baptism of John. ²⁶ And he began to speak boldly in the synagogue. When Priscilla and Aquila heard him, they took him aside and explained to him the way of God more accurately. ²⁷ When Apollos resolved to cross over to Achaia, the brothers encouraged him and wrote to the disciples there to welcome him. On his arrival, he was a great help to those who by grace had believed. ²⁸ For he powerfully refuted the Jews in public debate, proving from the Scriptures that Jesus is the Christ.

Word study "More accurately" - akribesteron (Acts 18:26)

Greek: ἀκριβέστερον (akribesteron), pronounced ah-kree-BES-ter-on. Strong’s G197.

Priscilla and Aquila explain the way of God more accurately. Apollos is gifted and sincere; he still needs fuller truth. Accuracy is love.

Eloquence, Scripture, fervor, accuracy - and a gap. John’s baptism without the fullness of Jesus’ finished work and Spirit-baptism leaves Apollos incomplete. A couple takes him aside. Akribesteron (ah-kree-BES-ter-on): more accurately. He receives. Letters of commendation follow. In Achaia he helps those who believed by grace and proves from Scripture that Jesus is the Christ. The chapter that began with tentmakers ends with multiplied teachers.

Study notes Going deeper

Presence that silences fear.

"Have I not commanded you to be strong and courageous? Do not be afraid; do not be discouraged, for the LORD your God is with you wherever you go." Joshua 1:9 (BSB)

Many people in this city. The Lord’s promise to Paul echoes election and mission: God has a people yet to believe, secured in His purpose.

"I have other sheep that are not of this fold. I must bring them in as well, and they will listen to My voice. Then there will be one flock and one shepherd." John 10:16 (BSB)

Teachability. Apollos shows that giftedness without humility stalls; giftedness under accurate teaching soars.

Hold the Lord’s night word as the chapter’s spine:

Personal Application

  1. Keep speaking. Where has fear muted your witness? What would trusting “I am with you” and “I have many people” change about your next conversation?

  2. Partners and trades. Aquila and Priscilla show ordinary work joined to gospel hospitality. How might your job, home, or skills become a base for mission rather than a wall against it?

  3. Taken aside. Are you willing to be Apollos - corrected privately - or Priscilla and Aquila - correcting gently? Where does accuracy need love, and love need accuracy?

Pray to Close

The central truth of Acts 18: the Lord stands with His witnesses in hard cities, forbids their silence, gathers a people for His name, and multiplies the word through partners, long teaching, and teachable servants.

Praise - the Christ who is Jesus, the Lord who speaks in the night, the grace by which any of us believe.

Confess - fear that silences, isolation that refuses help, pride that will not learn, haste that will not stay eighteen months when love requires it.

Ask - for courage, accurate teaching, gentle mentorship, and joy in every Crispus and Corinthian who believes.


Worship for Today

Jesus Messiah · Chris Tomlin

Corinth and Apollos both turn on one confession: Jesus is the Christ - the Messiah who saves. Tomlin’s song names Him with clarity Paul would recognize: light of the world, name above names, rescue for sinners. Sing it as eighteen months of teaching compressed into praise.
