Missions is the overflow of our delight in God because missions is the overflow of God's delight in being God.
John PiperA saving knowledge of Christ crucified and risen is not the mere result of right reasoning about historical facts. It is the result of spiritual illumination to see those facts for what they really are: a revelation of the truth and glory of God in the face of Christ-who is the same yesterday today and forever.
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 PiperThis is the centre of the gospel - this is what the Garden of Gethsemane and Good Friday are all about - that God has done astonishing and costly things to draw us near.
John PiperAccording to the spirit of this age, the ultimate sin is no longer the failure to honor and thank God but the failure to esteem oneself. Self-abasement, not God-abasement, is the evil. And the cry of deliverance is not "O wretched man that I am, who will deliver me?" but "O worthy man that I am, would that I could only see it better"!
