"Nevertheless, I have this against you; You tolerate this 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." Revelation 2:20
Jesus comes to the church in Thyatira. He commends them for their deeds by acknowledging their deeds, love, faith and service and that they are doing more than they were in the beginning. He reminds them of who he is by telling them that "these are words of the Son of God, whose eyes are like blazing fire and who feet are like burnished bronze." Jesus was reminding Thyatira of who he is, he is holy and righteous. His blazing eyes can see what is going on and that he is looking for us to be refined by fire and purge unrighteousness from our lives. He bronze feet represent power and strength which clearly shows that he will crush his enemies underfoot.
The church in Thyatira had a tendency to tolerate sin in the church. They also tolerated unrighteous and unbiblical teachings in its leaders. They were teaching doctrine that appealed to the flesh. It gave grace and more grace with no accountability to pick up their cross and follow Jesus. It did not require them to submit to the lordship of Christ. Jezebel appeals to the flesh and justifies the self. He knew that this spirit would lead his servants astray and cause them to give into sexual immorality and idolatry.
Jezebel in the old testament married Ahab and this lead to the worship of Baal and Asheroth. She led Israel astray by these practices an adulterous relationship with other gods. She could influence many with her charisma as well as manipulate and seduce others. She appealed to the flesh. Jezebel was a spiritual leader like the church of Thyatira. She would teach and lead others using the word of God to her advantage. She was self-appointed to that position rather than being God appointed. Many looked to her because of her power and position.
The church in Thyatira tolerated her and allowed for her to teach and to lead others. This spirit tolerated sin and seduced believers. She did not address sin, but appealed to their flesh. She made them feel good rather than allowing conviction to come in and transform them by the power of the Holy Spirit.
Jesus comes and gives Jezebel time to repent as well as those that follow her. He warns them that if they do not repent that they will also be deal with. That they will suffer with her. He tells them that he will strike her children dead, which means that they will die spiritually. He is looking to circumcise and purify the hearts of his believers. He clearly defines her practices and teachings as those of Satan. He promises for those who will repent and overcome that he will give authority over the nations and that he will give them the morning star, who is Christ himself.
