Ephesus is estimated to have been the fifth largest city in the Roman Empire. It was a major center of materialism, the occult, and the pagan worship of Artemis, whose temple was one of the seven wonders of the ancient world. Yet within three years, the city was transformed. The worship of Artemis had declined precipitously and Ephesus had become a church-planting hub for the entire region. God brought about a major reformation that began with thoughtful preparation and the proclamation of Jesus Christ. God continues to work in the same way today as we proclaim the same Savior who set us free.
