Worship must be shaped by truth. Jesus said, “Those who worship Him must worship in spirit and truth” (John 4:24). Psalm 29:2 calls us to “ascribe to the Lord the glory due His name.” Joel Beeke notes that worship divorced from doctrine becomes idolatry. Doctrine safeguards the church’s worship, ensuring it is not built on human invention but grounded in God’s holiness and His revealed Word.
