This podcast explores the theological concept of immortality, defining it as an independent, self-sustaining physical state that renders a being immune to death, aging, and decay. This study argues that while God is the sole inherent source of immortality, He created angels as inherently immortal spiritual beings and initially sustained mortal humanity through the Tree of Life. Following the fall of Adam and Eve, humanity lost access to this supernatural rejuvenation, activating a gradual genetic degeneration and shortening of the human lifespan. Ultimately, the study distinguishes temporary, gift-based immortality from God's unique absolute eternity, concluding that redeemed humans will eventually receive glorified, non-fleshly bodies to serve as an eternal trophy of divine grace across the cosmos.
