TerKeurst underscores the importance of choosing grace over bitterness in the face of rejection and loss. She argues that while it's natural to feel anger and crave justice, embracing grace is key to healing. 'Grace given when it feels least deserved is the only antidote for bitter rot,' she explains. By choosing grace, we allow healing and growth to take place even when life doesn't offer us the fairness we crave. This approach helps to prevent bitterness from taking root and allows for emotional and spiritual healing.
