C.S. Lewis, in "The Screwtape Letters," explores the concept of self-identity in relation to one's relationship with God. He suggests that when God speaks about individuals losing themselves, He refers to the need to let go of selfish desires and personal will. This abandonment is not a loss of personality but rather a transformation that leads to a fuller, richer self.

Ultimately, Lewis asserts that by surrendering to God, individuals reclaim their true selves. God promises that when they wholly belong to Him, they will actually become more authentic and complete, revealing the potential for their personalities to flourish in divine alignment.
