The 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.
John PiperThe ultimate difference between God's wisdom and man's wisdom is how they relate to the glory of God's grace in Christ crucified. God's wisdom makes the glory of God's grace our supreme treasure. But man's wisdom delights in seeing himself as resourceful, self-sufficient, self determining, and not utterly dependent on God's free grace.
John PiperIf my life was to have a single, all-satisfying, unifying passion, it would have to be God's passion.
