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 vast majority of abortions are performed between the seventh and tenth week when the baby is already sucking his thumb, recoiling from pricking, responding to sound. All his organs are present, the brain is functioning, the heart is pumping, the liver is making blood cells, the kidneys are cleaning fluids, and there is a fingerprint. His genetic code is uniquely and unquestionably human. And, if we are willing, he can be seen by ultrasound.
John PiperA woman who fears the Lord will not run away from God to satisfy her longings and relieve her anxieties. She will wait for the Lord. She will hope in God. She will stay close to the heart of God and trust in his promises. The prospect of departing into the way of sin will be too fearful to pursue; and the benefits of abiding in the shadow of the Almighty too glorious to forsake.
John Piper
