God is not worn out running the galaxy. He’s not taxed at all guiding every dust particle all the time.
John PiperGod took the record of all your sins-all your sexual failures-that made you a debtor to wrath, and instead of holding them up in front of your face and using them as the warrant to send you to hell, he put them in the palm of his Son’s hand and nailed them to the cross.
John PiperWhy Christians do what they do is just as important as what they do. Bad motives ruin good acts.
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
