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 PiperFaith stands or falls on the truth that the future with God is more satisfying than the one promised by sin. Where this truth is embraced and God is cherished above all, the power of sin is broken. The power of sin is the power of deceit. Sin has power through promising a false future. In temptation sin comes to us and says: "The future with God on his narrow way is hard and unhappy, but the way I promise is pleasant and satisfying." The power of sin is in the power of this lie.
John PiperLove is doing what will enthrall the beloved with the greatest and longest joy. What will enthrall the beloved this way is the glory of God. Love means doing all we can, at whatever cost to ourselves, to help people be enthralled with the glory of God. When they are, they are satisfied and God is glorified. Therefore loving people and glorifying God are one.
John PiperYou have to decide what those issues are for you. What do you think disqualifies a person from holding public office? I believe that the endorsement of the right to kill unborn children disqualifies a person from any position of public office. It's simply the same as saying that the endorsement of racism, fraud, or bribery, would disqualify him - except that child-killing is more serious than those.
