Envy is pain and grief that is felt when we observe another’s good or happiness. Envy often manifests itself in anger and contention toward others, wanting to cause harm to their good. It is a lack of contentment that robs us of joy, delight in God, and thankfulness. Envy usually occurs in conjunction with the sins of greed, pride, and selfishness.
ENVY in the heart says things such as: "I just hate them!" "I hate that others have good things and are happy." "I would be happy if I had what someone else has."
