Acts 19: Who is great in Ephesus?

Ephesus was a great city with the great temple of Artemis, one of the Seven Wonders of the world. In his third mission trip, Paul taught first in a synagogue but he was not welcomed; so he decided to teach daily in the School of Tyrannus to gentiles. The Lord opened the eyes of the city to the point that Demetrius goddess sales plummeted. For him, the gospel preached by Paul was destroying the city, was destroying the great Artemis, but who was great in Ephesus? Certainly, Jesus, although not using strength. That is why Paul had to flee from Ephesus.
