John Piper: The Gospel of God's Glorious Grace

“The gospel is the good news that God is the all-satisfying end of all our longings, and that even though he does not need us, and is in fact estranged from us because of our God-belittling sins, he has, in the great love with which he loved us, made a way for sinners to drink at the river of his delights through Jesus Christ.

And we will not be enthralled by this good news unless we feel that he was not obligated to do this. He was not coerced or constrained by our value. He is the center of the gospel. The exaltation of his glory is the driving force of the gospel. The gospel is a gospel of grace! And grace is the pleasure of God to magnify the worth of God by giving sinners the right and power to delight in God without obscuring the glory of God.” [via]
