Let us therefore cast aside the works of darkness and put on the armor of light.  - Rom 13:12

Reflection.  Envy is sadness over the good fortune of another.  Learn to spot that sadness when it arises in your heart, and then stamp it out.  Focus on your own unique qualities, not what you lack.  Do not allow sadness to rule your heart.

Prayer.  Lord, let me praise You when I resent the good fortune of others.
