What does the Bible say about spiritual idolatry?

Spiritual idolatry occurs when individuals or congregations deviate from the true gospel and abandon the teachings of Christ, which leads to severe consequences. In Revelation 2:20-23, the Lord rebukes the church at Thyatira for allowing a false prophetess, symbolic of spiritual idolatry, to seduce His servants into compromising their faith. This echoes the biblical history of Israel where idolatry led to judgment, and its warning extends to the church today. By mingling the worship of God with idolatrous practices, believers risk the severe repercussions of divine judgment and discipline.
