Which cities did Les say were all in the same geographical area?
Colossae, Ephesus, Pergamos, and Thyatira were all located in the same geographical area. That area is Asia Minor, with Ephesus on the western coast of Turkey. Paul’s greatest work occurred among those cities in that region. They were all in that same geographical area.
Les explains that Paul’s ministry reached all the way to the western coast of Turkey, where Ephesus was located. In that area of Asia Minor, Paul had his greatest work, and the cities his listeners would know—Colossae, Ephesus, Pergamos, and Thyatira—were all clustered in that same geographical area. He then notes the upcoming study of Paul’s synagogue message in Antioch of Pisidia, distinguishing it from the Antioch in Syria.
