How does envy affect our relationships according to the Bible?

The Bible illustrates that envy can have dire consequences on relationships, as evidenced by Saul's jealousy of David. Saul's envy exemplified human nature's inclination toward malice when threatened by another's success. This animosity not only led Saul to seek David's harm but also corrupted his heart. Proverbs 14:30 states, 'A tranquil heart gives life to the flesh, but envy makes the bones rot.' This underscores the destructive nature of envy, which can poison even familial bonds and community ties, emphasizing the need for Christians to cultivate a heart of love and support rather than jealousy.
