3rd Quarter, 2026
Lesson 1 (June 27 - July 3, 2026)
Paul's Ministry in Corinth
Memory Verse: "Do not be afraid, but speak and do not be silent; for I am with you, and no one will lay a hand on you to harm you, for there are many in this city who are my people" (Acts 18:9, 10, NRSV).
Lesson 1, Paul's Ministry in Corinth, opens the third quarter by introducing us to one of the most complex, troubled, and ultimately beloved congregations in the New Testament. First and Second Corinthians are not polished letters written to a model church. They are the honest, sometimes painful correspondence between a pastor who deeply loves his people and a congregation that is struggling -- with division, immorality, identity, and the pull of the culture around them. Sound familiar?
Before we can understand Paul's letters, we need to understand the city. Corinth was one of the most strategically located cities in the Roman world -- a wealthy port city with two harbors, a thriving economy, fierce religious pluralism, and a well-known reputation for sexual immorality. Paul chose it deliberately, because a church planted there would send the gospel in every direction. Yet when he arrived, he came by his own admission in weakness, fear, and much trembling -- alone, without his team, and apparently wondering whether Corinth was even worth the effort.
Paul -- A God-Called Apostle
Paul opens every major letter by identifying himself as an apostle called through the will of God -- not appointed by men, not self-appointed. His identity was anchored in three things: his encounter with the risen Lord, his commissioning to preach to the Gentiles, and the fruit of his ministry in transformed lives and new churches. This clarity of identity was not arrogance. It was the anchor that held him steady when the opposition came.
Paul's Strategy in Corinth
Paul's approach was deliberate. He began at the synagogue on Sabbath, engaging Jewish listeners on familiar scriptural ground. When opposition hardened, he shifted to the house of Titius Justus next door. He supported himself by making tents alongside Aquila and Priscilla. And he was determined, in his own words, not to know anything among the Corinthians except Jesus Christ and Him crucified -- not an anti-intellectual statement, but a theological one. The cross was not one topic among many. It was the center of everything.
God's Encouragement in the Night
At the point when Paul was seriously considering leaving Corinth, Christ appeared to him in a vision: Do not be afraid. Speak. I am with you. I have many people in this city. That word changed everything. Paul stayed eighteen months -- long enough to establish a church that would need two major letters and multiple visits to nurture. The church that grew was difficult, messy, and magnificent.
Christ Connection
Paul's strategy, his endurance, and his identity were all rooted in one thing -- Jesus Christ and Him crucified. He was not building a movement around his own personality. He was pointing people to a Person. That same simplicity is still the most powerful thing any believer can offer a complicated world.
Applications
1. Reflect on your own calling -- the specific work God has placed in your hands. Are you doing it?
2. If you have been avoiding a difficult mission field -- a person, a relationship, a community -- ask God for the courage Paul received in that night vision.
3. Let the cross be your center this week -- not a theological starting point but a daily returning point.
4. Pray for your local church -- not that it would be perfect, but that it would be faithful.
5. Read Acts 18:1-11 this week and notice how God provides for and encourages His servants in difficult places.
Discussion / Reflection Questions
- Paul rooted his identity entirely in his calling from God -- not in his education or achievements. Why is a clearly defined God-given identity so important for effective Christian mission -- and what happens when we lack it?
- Corinth was wealthy, religiously plural, and morally permissive -- and Paul chose it deliberately as his strategic base. What does that choice reveal about how the gospel should engage with difficult cultural environments rather than avoiding them?
- Paul arrived in weakness, fear, and much trembling -- and God met him with a vision rather than removing the difficulty. What does that pattern reveal about how God typically works with His servants in mission?
- Paul was determined to know nothing among the Corinthians except Christ crucified. In a world full of competing ideas, why is that singular focus still the most powerful thing the church can offer -- and how easy is it to lose?
- The church Paul planted in Corinth was difficult and messy yet he stayed eighteen months to build it. What does his commitment to a troubled congregation say about what faithfulness in ministry actually looks like?
