Sibling rivalry affects nearly half of adult sibling relationships, making it one of the most harmful family dynamics. The biblical story of Joseph provides powerful insights into overcoming this universal struggle. When Joseph's brothers return to Egypt during a famine, he tests them by giving Benjamin preferential treatment—mirroring the favoritism that once sparked their jealousy toward Joseph. Remarkably, the brothers show no resentment, demonstrating their transformation. This change came through experiencing God's overwhelming grace and mercy in their lives. Similarly, we can overcome jealousy not through willpower but by focusing on God's blessings in our own lives, allowing gratitude to replace envy.
