“At thy right hand there are pleasures for evermore” (Ps. 16:11)
“I know thy works, and charity, and service, and faith, and thy patience, and thy works; and the last to be more than the first. Notwithstanding I have a few things against thee, because thou sufferest that woman Jezebel, which calleth herself a prophetess, to teach and to seduce my servants to commit fornication, and to eat things sacrificed unto idols” (Rev. 2:19–20).
The church at Thyatira was an industrious, hard-working church. In speaking to them, the Lord begins by 
commending them for their labors. He uses a number of overlapping terms to do so—He praises their works, using that work twice, once at the beginning and the other at the end of the list. He commends their works, and then their love, and their faith, and their steadfastness, and then their works again. The works at the end of the list were greater than the works at the beginning. Their labors were growing in volume and intensity. The church at Ephesus worked hard also, but had fallen from their first love. The church at Thyatira was given over to ever-increasing works, but they were also commended for their love (agape). All in all, they appeared to be a healthy church.
But there was a problem. A woman who was a false teacher, styling herself as a prophetess, was seducing servants of Christ (the Lord calls them my servants) into fornication, and into participation in idolatrous feasts. She was here given the pseudonym of Jezebel, after the Phoenician queen who introduced Baal worship into Israel in the time of Elijah. The charge against the church at Thyatira was that they tolerated her.
