v1-3: Meeting with Aquila and Priscilla in Corinth; this couple are later much used of the Lord, helping Apollos, v24-28; being fellow workers with Paul, even risking their lives for the sake of the gospel, Rom 16.3-4. They have already suffered persecution at the hands of the Romans. We see value in ‘ordinary’ work, in that Paul came into contact with Aquila and Priscilla through this. See 20.34-35, where Paul implies that this work enabled him to continue his ministry.
Ancient cities contained numerous guilds of local trades. Thus, we would expect Paul would find fellow tentmakers easily, as they were located together.
It is sometimes assumed that a Church leader is necessarily ‘full-time’ and paid by the local Church. Whilst this is a common pattern it is not commended in Scripture. Paul himself addresses the question in 1 Cor 9.3-6.
In most nations in most times in history, a local Church is financially ill-equipped to pay a full-time salary to a Church leader. And Paul models this here. Paul stayed in Corinth for some time, establishing the Church. But he seems to have worked as a tent-maker to support himself and so as not to be a financial burden on the Church. ‘St Paul’s theory of evangelizing a province was not to preach in every place in it himself but to establish centres of.Christian life in two or three important places from which knowledge might spread into the country around.’ (Roland Allen, Missionary Methods)
v4: Again, Paul goes into the synagogue in Corinth.
v5: Paul gave himself exclusively to preaching. He had learned a flexibility in relaiton to his tent-making and preaching. Sometimes he worked on tents, in partnership with Aquila and Priscilla. At other times he preached. Sometimes he did both. In 1 Cor 9.6 he refers to working for a living.
v6: Paul meets opposition from the Jews; he is now constrained to go to the Gentiles, 13.46; this was always the Lord's call upon his life, see 9.15.
v7-8: There are key converts; Justus, who lives next door to the synagogue, and Crispus the ruler of the synagogue. Many other Corinthians are converted.
v9-10: Special encouragement from the Lord. It may be that repeated attacks from the Jews, which seem more frequent and violent (17.1-15) have begun to discourage him. He is tempted to move on. We have every confidence in our God who cares for us, and who strengthens us. We know too that any opposition is restrained and limited by God.
v11: With God's encouragement, Paul remains for 18 months in Corinth. Many adversaries become many opportunities.
v12-13: Paul is arrested for his activities; it is as well that he has been encouraged by the Lord, although this incident is apparently some time after his arrival in Corinth.
v14-17: Gallio the proconsul is not interested in maintaining justice and peace. He just wants a quiet life, like Pilate. He avoids making any proper decision. The new synagogue ruler, Sosthenes, receives the fresh anger of the Jews.
v18-22: Paul's vow, and his return to Jerusalem for the feast; evidence of a continuing loyalty to Judaism, although little is made of it here.
Paul leaves Priscilla and Aquila at Ephesus, a key city, and returns to Antioch.
v23: Paul begins his third missionary journey, returning to the churches to strengthen the disciples. Here is thorough follow-up of new believers.
v24-28: The disciple; willing to learn from more mature and experienced Christians. Apollos is already eloquent and effective; and through Priscilla and Aquila, he learns the way of truth more clearly; he begins to preach that Jesus is the Christ. He is sent to Achaia (Corinth, etc.) to help the Christians there.
