Old Testament Scripture: Isaiah 26:3 | PERFECT PEACE  Thou wilt keep him in perfect peace, whose mind is stayed on thee: because he trusteth in thee. Isaiah 26:3  Perfection: involves completeness, in the universal language mathematics perfection is usually measured as 100%.  Naturally: Nobody’s Perfect? Yet there are three people in the Bible who God called Perfect. (Feel free to use the comment section to name one two or three of them.)  Spiritually: The Blood of Jesus is 100% in its entire meaning it lacks nothing  This is the basis of the application of your peace.  NT SCRIPTURE: Rev 2:18-21 | REPENT 18 And unto the angel of the church in Thyatira write; These things saith the Son of God, who hath his eyes like unto a flame of fire, and his feet are like fine brass; 19 I know thy works, and charity, and service, and faith, and thy patience, and thy works; and the last to be more than the first. 20 Notwithstanding I have a few things against thee because thou sufferest that woman Jezebel, which calleth herself a prophetess, to teach and to seduce my servants to commit fornication, and to eat things sacrificed unto idols. 21 And I gave her space to repent of her fornication, and she repented not. Rev 2:18-21  Repentance comes after having perfect peace. When the spirit of error goes unchallenged for a considerable length of time, truth and repentance would effectively invalidate the system upheld by its presence. Without truth the courage to change is absent. On a micro-level, it is improbable that individuals who led by the spirit of Jezebel admit to their flaws. Soon it becomes impossible for those who have a reprobate mind to repent. Cain was given an opportunity to repent (Gen. 4:7) and Esau, yet both "found no place for repentance even when seeking it with tears" (Hebrews 12:17). The spirit of Jezebel’s typology is a consuming spirit but she shall be consumed at the end, as King Ahab’s wife was processed as mature by ravenous dogs after being trodden under horses’ hooves. The spirit of Jezebel becomes a central fixture working in the background of the church.  Christ will make an example out of this church, “And I will kill her children with death, and all the churches shall know that I am he which searcheth the reins and hearts” (Revelation 2:23).
