I'm still not a great reader, but my wife is and my daughters are, and I envy them. I think I got into a bad habit of trying to do something all the time, instead of trying to sit down and take my time a little bit.
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.
