In Jodi Picoult's novel "Keeping Faith," the author presents the idea that belief in God often stems from a lack of alternative explanations for life's complexities. Many individuals turn to faith when confronted with challenges or mysteries that seem beyond human understanding. This reliance on a higher power provides comfort and answers where logic may fall short.

As characters navigate their personal struggles in the story, the theme of faith emerges as a critical response to their unanswerable questions. The narrative suggests that, for some, the existence of God fills the gaps left by uncertainty, serving as a guiding force in moments of despair and confusion.
