ScriptureDepth's study of Acts 18
“The Lord said to Paul in the night by a vision, “Don’t be afraid, but speak and don’t be silent;”
Acts 18:9
The Lord assures Paul in a vision in Corinth, commanding him to speak boldly, which motivates his continued ministry and prevents fear as he teaches for a year and six months.
What Acts 18 is about
Paul arrived in Corinth after leaving Athens and met Aquila and Priscilla, who were tent makers like him (vv. 1-4). He reasoned in the synagogue every Sabbath and persuaded both Jews and Greeks (vv. 5-8). When Silas and Timothy arrived, Paul was compelled by the Spirit to testify that Jesus was the Christ, but faced opposition from some Jews. He then shifted his focus to the Gentiles (vv. 5-6). The Lord assured Paul in a vision, telling him not to be afraid and promising protection (vv. 9-11). When Paul faced accusations before Gallio, the proconsul, Gallio dismissed the case, stating it was a matter of their own law (vv. 12-17). Paul then traveled to Ephesus, leaving Priscilla and Aquila there (vv. 18-21). After returning to Antioch, he traveled through Galatia and Phrygia (vv. 22-23). Apollos arrived in Ephesus, taught accurately, and received further instruction from Priscilla and Aquila (vv. 24-28).
The Lord promised Paul, 'I am with you, and no one will attack you to harm you' (v. 10).

But when Paul was about to open his mouth, Gallio said to the Jews, “If indeed it were a matter of wrong or of wicked crime, you Jews, it would be reasonable that I should bear with you; 15Verse 15. but if they are questions about words and names and your own law, look to it yourselves. For I don’t want to be a judge of these matters.”

Main themes in Acts 18
Perseverance in Ministry
In vv. 5-6, Paul is compelled by the Spirit to testify to the Jews about Jesus as the Christ, despite their opposition. When they blaspheme, he declares, 'Your blood be on your own heads! I am clean.' He then pivots to the Gentiles in verse 6. Paul's determination continues as he stays in Corinth for a year and six months, teaching and strengthening the believers there (v. 11).
Divine Guidance
In vv. 9-10, the Lord speaks to Paul in a vision, saying, 'Don’t be afraid, but speak and don’t be silent; for I am with you.' This reassurance comes during a time of opposition, indicating divine support. The promise that 'I have many people in this city' (v. 10) suggests that God has prepared the way for Paul's ministry, encouraging him to continue despite challenges.
Community and Cooperation
In vv. 2-3, Paul meets Aquila and Priscilla, fellow tent makers, forming a partnership that supports his ministry. Their collaboration is evident in v. 26, where they take Apollos aside to explain 'the way of God more accurately.' This interaction illustrates the mutual support among early believers, as they work together for the advancement of the Gospel.
Growth of the Church
The growth of the church in Corinth is evident in v. 8, where Crispus, the ruler of the synagogue, believes along with his household. The chapter describes many Corinthians who 'when they heard, believed and were baptized.' Additionally, Apollos’ ministry in v. 28, where he 'greatly helped those who had believed through grace,' illustrates the expanding influence of the early church and the integration of new leaders.
