Ephesus Ephesus stood at the crossroads of both north-south and east-west trade routes and was well known as the “guardian” of the temple of Artemis (Acts 19:35). It was founded by Ionian Greeks around 1044 BC on a natural harbor where the Cayster River emptied into a gulf of the Aegean Sea (the site of the ancient city is now well inland). The city came under Roman rule in 41 BC. At the time of the apostles, Ephesus was a wealthy city, a commercial and religious hub, and thus the most important city of the Roman province of Asia. The worship of Artemis in Ephesus was nearly as ancient as the city itself. The temple of Artemis, one of the seven wonders of the ancient world, was a key to the wealth and commerce of Ephesus, because the worship of Artemis brought many pilgrims to Ephesus and provided many commercial opportunities for idol makers and other vendors of goods and services. When Paul arrived on his third missionary journey in AD 53 (Acts 19), Ephesus had been a city continuously for over a thousand years and was deeply devoted to its patron goddess and her temple.

The entire unbelieving world is subject to the power of sin and the devil (see Eph 2:2; 1 Jn 5:19). As the “god of this world,” the devil can blind the minds of unbelievers (see 2 Cor 4:4; cp. Matt 13:19). While Satan opposes God and seeks to destroy his people (Rev 12:12, 17), Jesus came to destroy Satan’s work (1 Jn 3:8). God turns what the devil intends for evil into good. Following this principle, Paul instructs the church at Corinth to expel someone from Christian fellowship in order that, by being exposed to the devil’s destructive power, that person might repent and be saved (see 1 Cor 5:5). Christians are to stand firm and resist the devil (Jas 4:7), praying for God’s deliverance (Matt 6:13) and availing themselves of the armor that God provides for their defense (Eph 6:10-20). Those who yield to Satan’s influence...
