Flaming Fire
The 'flaming fire' represents God's righteous judgment and His presence in executing justice upon those who do not know God and do not obey the gospel of our Lord Jesus.
This symbol underscores God's holiness and justice, emphasizing the certainty of divine retribution against evil and the vindication of His people.
Fire in biblical times often symbolized God's presence, purification, and judgment, as seen in sacrificial practices and divine appearances.
