What does Paul do on his first visit to Ephesus, at the end of his second missionary journey? (Acts 18:18-21).

 Ephesus was one of the largest cities of the Roman Empire, with a population of about 250,000. It was the capital of one of the Empire’s richest provinces, the province of Asia, which covered much of what we know today as Asia Minor. In Paul’s day, the province was enjoying a time of growth and prosperity. A port city, Ephesus was also at the crossroads of important land routes. While the people worshiped many deities in the city, Artemis, regarded as the protector goddess of the city, was supreme. Her worship was the focus of civic ceremonies, athletic games, and annual celebrations. (Artemis was called Diana by the Romans; see Acts 19:24, 35, KJV; NKJV.)

 Paul later returns to Ephesus on his third missionary journey (Acts 19:1-12), and remains there “for three years” (Acts 20:31). The apostle makes a significant time commitment to Ephesus, with the intention of firmly founding Christianity there.

 What strange event leads to widespread reverence for “the Lord Jesus” in Ephesus? (Acts 19:13-20).

 Luke shares the strange story of seven itinerant, Jewish exorcists in the city. Mingling the names of both Jesus and Paul in their incantations proves to be a misguided venture for these exorcists. When the news flashes through the streets of the city, “everyone was awestruck; and the name of the Lord Jesus was praised” (Acts 19:17, NRSV). The event also had a profound impact on some of those who had already become believers, who publicly burned their expensive handbooks of magic arts, worth “fifty thousand silver coins” (Acts 19:19, NRSV). With the wider residents of the city, believers learn that the worship of Jesus must not be diluted with the worship of anything or anyone else.
