God created us to live with a single passion: to joyfully display his supreme excellence in all spheres of life. The wasted life is the life without this passion. God calls us to pray and think and dream and plan and work, not to be made much of, but to make much of him in every part of our lives.
John PiperTo see Him and know Him and be in His presence is the soulโs final feast. Beyond this there is no quest. Words fail. We call it pleasure, joy, delight. But these are weak pointers to the unspeakable experience.
John PiperWhat is the essence of evil? It is forsaking a living fountain for broken cisterns. God gets derision and we get death. They are one: choosing sugarcoated misery we mock the lifegiving God. It was meant to be another way: God's glory exalted in our everlasting joy.
John PiperSo saving grace, converting grace, for Augustine, is God's giving us a sovereign joy in God that triumphs over all other joys and therefore sways the will. The will is free to move toward whatever it delights in most fully, but it is not within the power of our will to determine what that sovereign joy will be.
John Piper
