Thyatira is a city in Asia Minor.
Lydia, Paul's co-worker, was from here.
Acts 16:14A woman named Lydia, a dealer in purple cloth from the city of Thyatira, who was a worshiper of God, was listening. The Lord opened her heart to respond to Paul’s message.Acts 16:15When she and her household had been baptized, she urged us, “If you consider me a believer in the Lord, come and stay at my house.” And she persuaded us.
In the book of Revelation, the church in Thyatira is commended for its love, faith, service, and perseverance, which had increased more than at first.
Rev 2:19I know your deeds, your love and faith, your service and perseverance, and that your latter deeds are greater than your first.
However, it was rebuked for tolerating the false prophetess Jezebel.
Rev 2:20Nevertheless, I have this against you: You tolerate that woman Jezebel, who calls herself a prophetess. By her teaching she misleads my servants into sexual immorality and the eating of food sacrificed to idols.Rev 2:21I have given her time to repent of her immorality, but she is unwilling.Rev 2:22So I will cast her on a bed of suffering, and I will make those who commit adultery with her suffer intensely, unless they repent of her ways.Rev 2:23I will strike her children dead. Then all the churches will know that I am he who searches hearts and minds, and I will repay each of you according to your deeds.
