Psalm 37:4 NIV: Delight yourself in the LORD and he will give you the desires of your heart.
Jesus told us that "whosoever will save his life shall lose it: and whosoever will lose his life for [Jesus´] sake shall find it" (Matthew 16:25). Our greatest rewards will come when we do not seek them. As we seek to "lose" our lives, we open ourselves up to be the instruments of God´s purpose, to accomplish His will on earth. Living this way will bring us great rewards, and that is because we do not seek rewards. We do not seek to store up treasures in heaven and we do not do our righteous acts so that God will reward us--we simply do them because--and we require nothing in return. If our only reason to live the Christian life is to gain better reward then we have missed the point. Following Christ means sacrifice of our wants and giving up of personal desires so that God´s greater good will prevail.
