What does Revelation 2:2 mean?
Jesus commends the church at Ephesus for its diligent work and patience in suffering. The Ephesian church existed in the midst of a mixture of Greek and Oriental cultures. This included a variety of false religions. The worship of the fertility goddess Diana was rampant in Ephesus, and the temple in which her worshipers adored her was one of the seven wonders of the world. Superstition and magical arts flourished throughout the region. It is not surprising, therefore, that the church at Ephesus experienced persecution.Nevertheless, the Ephesian Christians held their ground. They did not compromise the truth in order to be acceptable to the general population. Nor did they tolerate evildoers: their love of truth caused them to test those who professed to be apostles, and to conclude that the self-proclaimed apostles were false. Interestingly, false teachers were threatening not only the church at Ephesus but also the church in Smyrna, the church in Pergamum, and the church in Thyatira (Revelation 2:2, 6, 9, 14–15, 20).
While this commitment to truth is certainly commendable, the Ephesians were not applying it in an entirely positive way, as later verses will point out.
