It was becoming clearer and clearer that if I wanted to come to the end of my life and not say, โIโve wasted it!โ then I would need to press all the way in, and all the way up, to the ultimate purpose of God and join him in it. If my life was to have a single, all-satisfying, unifying passion, it would have to be Godโs passion.
John PiperWhat is sin? It is the glory of God not honored. The holiness of God not reverenced. The greatness of God not admired. The power of God not praised. The truth of God not sought. The wisdom of God not esteemed. The beauty of God not treasured. The goodness of God not savored. The faithfulness of God not trusted. The commandments of God not obeyed. The justice of God not respected. The wrath of God not feared. The grace of God not cherished. The presence of God not prized. The person of God not loved. That is sin.
