It is unfortunate that there are those who have added to Scripture to claim that an evil woman of the Old Testament is now a female demon going about influencing mostly women to be like her in Christian churches.
There is no biblical ‘spirit of jezebel’. What there is, is a real woman who lived and died. Her spirit went to the place that God provides until the judgement. Her spirit does not roam the earth in the form of a demon and influence people. Real demonic spirits have a name that describes evil characteristics. They are not given names like Tom, Dick or Harry. The things that the real Jezebel did were the actions of a person who did not believe in or submit to God. The real Jezebel taught irreverently against God and encouraged sexual immorality. If you were to more correctly say “in the manner of” or “in the attitude of” the woman Jezebel, you could still not correctly apply this to born again believers in Christ the Messiah who did not promote sexual immorality.
Hear this again, Jezebel was not a believer in God. She taught against Elohim and was a worshipper of Baal, whose worship invovled sexual looseness of degrading qualities. She was not just controlling but was cruel. In 1 Kings 18:4 she took a hundred of Israel's prophets, hid them in a cave feeding them only bread and water and then killed them all. She put altars to Baal where ever she could. Relentlessly, she sought to murder God's leaders including Elijah. Instead, God brought judgement upon her and her own eunuchs threw her to her death. (2 Kings 9:29-37)
Those who love God's Word do not misuse it by comparing such a wicked non-believer to one of God's own servants, no matter their imperfections. This false teaching of anyone (especially women) having A "spirit of Jezebel" has gone so far away from Biblical truth that it absolutely needs to be challenged, exposed and removed from Christian language.
There are demons that promote activity like the kind that Jezebel engaged in. Those actions would be immorality, idolatry, false teaching, unrepentant sin and the like. Certainly there might be one or some of those dark spirits influencing someone's life. But those would be the names, not a human name. Using a human name of a dead person encourages the possibility of misuse and of falsely characterizing innocent people to have all the same evil inclinations that Jezebel had.
