In Nick Hornby's book "How to Be Good," the narrator reflects on personal sins and their perception of morality. They believe that acknowledging one's own wrongdoings is integral to understanding their significance. This introspection leads to a fascination with the concept of born-again Christianity, which offers a sense of renewal and starting afresh.

The idea of rebirth resonates deeply, as many people yearn for a clean slate in life. This longing for a fresh beginning often overshadows the principles of Christianity itself, suggesting that it's the transformative aspect of rebirth that captivates individuals rather than the faith's teachings. Hornby's exploration highlights the human desire for redemption and the possibility of change.
