The quote from C.S. Lewis's "The Screwtape Letters" emphasizes the peril that the character Wormwood faces when humans, despite feeling abandoned by God, choose to obey His will. This situation is particularly dangerous because it indicates a deep internal struggle between desire and intention, where the individual continues to act righteously even in the absence of divine reassurance.

This highlights the resilience of faith in challenging times. The struggle against despair, while holding onto hope and commitment to doing good, is portrayed as a significant threat to evil forces, suggesting that genuine obedience can triumph in the face of doubt and hardship.
