How do we know the doctrine of idolatry is true?

The doctrine of idolatry is established through Biblical teaching and the historical accounts of Israel, where idolatry is consistently condemned. Not only does the Old Testament document Israel's repeated engagements with idolatry, showcasing God's displeasure with such acts, but the prophets also announce severe judgments against both ancient and contemporary idolatries. For instance, Isaiah expresses God's jealousy and His commitment to punishing those who fall into idolatry (Isaiah 42:8). Furthermore, Paul's admonitions to flee from idolatry in the New Testament reinforce the belief that idolatry is a continual, ongoing threat. The presence of idolatry in the church and society throughout history, alongside the prophetic warnings, underlines the seriousness and truth of this doctrine.
