When Paul was in Ephesus he met much resistance to preaching the gospel of Jesus Christ
24 "For a certain man named Demetrius, a silversmith, which made silver shrines for Diana, brought no small gain unto the craftsmen;
25 Whom he called together with the workmen of like occupation, and said, Sirs, ye know that by this craft we have our wealth.
26 Moreover ye see and hear, that not alone at Ephesus, but almost throughout all Asia, this Paul hath persuaded and turned away much people, saying that they be no gods, which are made with hands:
27 So that not only this our craft is in danger to be set at nought; but also that the temple of the great goddess Diana should be despised, and her magnificence should be destroyed, whom all Asia and the world worshippeth.
28 And when they heard these sayings, they were full of wrath, and cried out, saying, Great is Diana of the Ephesians."
Yet, these idols keep people in spiritual bondage and made some craftsmen very rich, so Paul's teaching of Jesus Christ was opposed.
