"What does the bad eye refer to in Matthew 20:15? It refers to an eye that cannot see the beauty of grace. It cannot see the brightness of generosity. It cannot see unexpected blessing to others as a precious treasure. It is an eye that is blind to what is truly beautiful and bright and precious and God-like. It is a worldly eye. It sees money and material reward as more to be desired than a beautiful display of free, gracious, God-like generosity."
(from John Piper - Desiring God)
