From "A Grief Observed" by CS Lewis

...'But it could also mean-'This had reached its proper perfection. This had become what it had in it to be. Therefore of course it would not be prolonged." As if God said, "Good; you have mastered that exercise. I am very pleased with it. And now you are ready to go onto the next."
