So 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 PiperSpiritual leadership is knowing where God wants people to be and taking the initiative to get them there by God's means in reliance on God's power.
John PiperThat's who Jesus Christ is. He became the final Priest and the final Sacrifice. Sinless, he did not offer sacrifices for himself. Immortal, he never has to be replaced. Human, he could bear human sins. Therefore he did not offer sacrifices for himself; he offered himself as the final sacrifice. There will never be the need for another. There is one mediator between us and God. One priest. We need no other. Oh, how happy are those who draw near to God through Christ alone.
John PiperWe give glory to God when we trust him to do what he has promised to do-especially when all human possibilities are exhausted. Faith glorifies God. That is why God planned for faith to be the way we are justified.
John PiperIt was becoming clearer and clearer that if I wanted to come to the end of my life and not say, “I’ve wasted it!” 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 God’s passion.
