"A sound heart is life to the body, but envy is rottenness to the bones. "Proverbs 14:30
When one lives by faith, one's eyes are like God's eyes: they want the best for others. On the other hand, when there's envy, there are evil eyes, that consequently mean the person's interior is in darkness. There's an evil spirit in dominion of this person's life and he or she certainly needs deliverance.
