What does the Bible say about God's nature as a consuming fire?

Hebrews 12:29 states, 'Our God is a consuming fire.' This declaration highlights God's unchanging nature and His holiness, transcending both the old and new covenants. While the old covenant warned of God's fiery nature as a deterrent against sin, the new covenant reveals His consuming fire as a warning for believers to remain steadfast in Christ, the only refuge from divine wrath. God's consuming fire serves both to instill a proper fear of Him and to underscore the grace extended through Christ, who bore the full weight of that fire on our behalf.
