The quote emphasizes the idea that although negativity and challenges exist in the world, positivity and hope ultimately prevail. The metaphor of a candle representing light illustrates that one cannot overshadow positivity with darkness, but instead, one can pursue light in difficult times. It suggests a choice between embracing despair or seeking enlightenment and hope.

The author, Jodi Picoult, expresses a personal belief that faith in Christ embodies that light, guiding individuals through life's hardships. This perspective encourages readers to seek out positive influences in their lives and to actively choose hope over despair in the face of adversity.
