What does Revelation 2:20 mean?
This verse reveals Jesus' complaint against the church at Thyatira: it "tolerated" a false prophet named Jezebel. This dangerous woman was persuading members of the church to practice immorality and idolatry. Apparently, she promoted certain pagan sexual practices. Also, she condoned a common practice at trade union banquets, namely the eating of food dedicated to idols.Strictly speaking, we do not know who this woman was. The name Jezebel may have been her actual name or simply a pseudonym. In the Old Testament, Jezebel was the wife of King Ahab of Israel. She was a vicious, violent woman, who promoted the worship of Baal, the sun god, and killed many of God's prophets. Also, she sought unsuccessfully to kill the prophet Elijah (1 Kings 16—22). Some Bible scholars believe the Jezebel referred to here, in Jesus' letter to the church of Thyatira, may have even been the wife of the church's pastor. Whatever her role in the church, she was extremely influential.
Revelation 2:18–29 reveals what Jesus instructed John to write to the church at Thyatira. Although the church exhibited commendable virtues, it allowed an evil woman—here referred to as Jezebel—to lead its members into immorality and idolatry. Jesus predicted strict punishment for her and her followers. The churches would know by Jesus' action that He searches the mind and heart and deals with everyone according to his or her works. Those who did not follow Jezebel's teachings would not be punished, but Jesus encouraged them to stay loyal to Him until His return, when He will rule the nations and permit the faithful to rule with Him.
The contents of Revelation 2 are miniature letters to four churches, dictated by Jesus to John. Ephesus and Smyrna were coastal cities, whereas Pergamum and Thyatira were inland cities. Three more such letters are in Revelation 3. Each of these messages contains a unique description of Jesus, a command, a promise. All but one—the church in Laodicea—receive some commendation. All but two of the seven letters—those to the churches in Smyrna and Philadelphia—also contain a critical rebuke. Like churches today, most of the congregations addressed by Jesus had both good characteristics and at least one point which needed correction.
