What happens when a faithful church begins to tolerate compromise? In this message from Revelation 2:18–29, Jesus speaks to the church in Thyatira—commending their love and service, yet confronting their dangerous tolerance of false teaching. The “Jezebel spirit” mixed truth with lies and seduced believers into immorality and idolatry. Jesus reveals Himself as the all-seeing Son of God whose judgment is powerful but whose discipline is loving. This sermon calls believers to reject compromise, guard truth, endure faithfully, and hold fast to Christ—because those who conquer will receive authority, victory, and the Morning Star: Jesus Himself.
