In "The Fiery Cross" by Diana Gabaldon, the theme of faith and the power of prayer is emphasized through the idea that God serves as a source of comfort and support in times of trouble. The quote suggests that instead of succumbing to worry, individuals should turn to prayer, highlighting its transformative power in overcoming challenges.

This message reinforces the belief that relying on faith can provide strength and guidance during difficult moments, while anxiety only diminishes one's peace of mind. The narrative encourages readers to embrace spirituality as a way to cope with life's uncertainties.
