Inner peace and contentment are physically and spiritually life-giving. Envy — wanting what others have and resenting them for it — is corrosive. It does not merely cause emotional harm; it destroys the whole person. The contrast is striking: life versus rottenness.
Memory phrase: Peace inside brings life.
Talk about it: How can wanting what others have hurt you on the inside?
Prayer: God, give me a peaceful, content heart.
