This sermon, based on Revelation 2:18–29, highlights Jesus' message to the Church at Thyatira, praising their growing faith, love, service, and endurance. However, it also delivers a strong warning against tolerating the destructive influence of a "Jezebel spirit"—marked by manipulation, control, rebellion, and unrepentant sin—which leads others into compromise and spiritual ruin. The message urges the modern church to uphold godly character, reject worldly influence, remain faithful to Christ, and protect the integrity of the Church at all costs.
