Acts 18:11

He continued. Gr. kathizo, “to sit down,” “to settle in a place.” The verb suggests permanence and continuance. A year and six months. The time spent in Corinth gave Paul opportunity not only for founding and organizing a church but also for working in the neighboring districts, such as the port of Cenchreae (see Rom. 16:1). Besides his preaching and teaching to the Corinthians, Paul wrote probably at this time the two epistles to the Thessalonians, which are considered the earliest of his letters, and perhaps the earliest literature of the whole NT, unless the Epistle of James is dated earlier. The address of 2 Corinthians (ch. 1:1), “unto the church of God which is at Corinth, with all the saints which are in all Achaia,” clearly indicates the spread of the gospel beyond the limits of the city. This extensive fruitage Paul recognized as a fulfillment of the Lord’s promise given him in vision, which prepared him for the coming of the next persecution.
