Galatians 6:9 "We must not get tired of doing good. We will receive our harvest of eternal life at the right time. We must not give up."
Luke 6:38 "Give to others, and you will receive. You will be given much. It will be poured into your hands--more than you can hold. You will be given so much that it will spill into your lap. The way you give to others is the way God will give to you."
So the next time the Green-Eyed Monster threatens to take over, stomp it down, pray, and tell it you have no use for it. Then go out and give to others in some way - bake cookies, send an encouraging note, surprise a friend with coffee - just go lift up someone else and you will be lifted too.
