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 PiperThe whole world lives for pleasure. The only difference is theirs is fleeting, while ours is forever in Jesus.
John PiperSleep is a daily reminder from God that we are not God. Once a day God sends us to bed like patients with a sickness. The sickness is a chronic tendency to think we are in control and that our work is indispensable. To cure us of this disease God turns us into helpless sacks of sand once a day.
John PiperBeing infinite, God is inexhaustibly interesting. It is therefore impossible that God be boring.
John PiperTaken as a whole, the story of Ruth is one of those signs. It was written to give us encouragement and hope that all the perplexing turns in our lives are going somewhere good. They do not lead off a cliff. In all the setbacks of our lives as believers, God is plotting for our joy.
John PiperThe point is not that the resurrection is the price paid for our sins. The point point is that the resurrection proves the death of Jesus is an all-sufficient price. If Jesus did not rise from the dead, then his death was a failure, God did not vindicate his sin-bearing achievement, and we are still in our sins.
