The answer is: Flaming sword

Gen 3:24

In the fascinating narrative of Genesis 3:24, after the pivotal moment of humanity’s expulsion from Eden, God sets cherubim and a flaming sword to guard the Tree of Life. This dramatic imagery catches our attention! Cherubim are not just ordinary angels; throughout the Bible, they often symbolize the majesty and mystery of God's heavenly realm. The flaming sword signifies a fierce protection, illustrating that remaining in their original state of innocence was no longer an option for humanity.

Trivia alert: Did you know that in ancient mythology outside the Bible, fire swords were often seen as symbols of divine power and progression? This echoes the sentiments found in Genesis. The flaming sword also represents the consequences of human actions and the barriers created by sin—ironically, a metaphor for turning away from the divine.

This piece of the story sets the stage for the greater narrative of redemption that courses throughout Scripture. After all, access to eternal life is a central theme. Much later in Revelation, the Tree of Life reappears, promising restoration and reunion. The use of imagery is profound; it invites readers to consider not merely the immediate consequences of actions but the overarching story of separation and eventual restoration with the divine. The adventure isn’t over yet!
