It is recorded that Paul labored a year and six months in Corinth. His efforts, however, were not exclusively confined to that city, but he availed himself of the easy communication by land and water with adjacent cities, and labored among them both by letter and personal effort. He made Corinth his headquarters, and his long tarry and successful ministry there gave him influence abroad as well as at home. Several churches were thus raised up under the efforts of the apostle and his co-laborers. The absence of Paul from the churches of his care was partially supplied by communications weighty and powerful, which were received generally as the word of God to them through his obedient servant. These epistles were read in the churches.{LP 109.1}

Der står skrevet at Paulus arbejdede et år og seks måneder i Korint. Hans anstrengelser var dog ikke kun i den by, men han benyttede den nemme forbindelse til lands og vands med nærtliggende byer, og arbejdede iblandt dem både med brev og personligt arbejde. Han gjorde Korint til hans hovedkvarter, og hans lange ophold og fremgangsrige forkyndergerning, gav ham indflydelse derude såvel som hjemme. Således blev de oprettet flere menigheder under apostlens og hans medarbejders anstrengelser. Paulus’ fravær fra de menigheder han havde, blev delvis dækket af vægtige og kraftfulde meddelelser, som blev modtaget i almindelig som Guds ord til dem, igennem hans lydige tjener. Disse breve blev læst op i menighederne.
