Verse 18: “And to the angel of the church in Thyatira write, ‘These things says the Son of God, who has eyes like a flame of fire, and His feet like fine brass:’”
The wrongdoing of the Church of Thyatira was allowing the teachings of Jezebel into the church. Jezebel, the wife of King Ahab, brought idolatry to Israel and seduced its people to commit sexual immorality and eat the sacrificial offerings to idols. By the description of Jesus as having “eyes like a flame of fire,” God is warning that He will rebuke and judge those who have wrong faith in His churches.
