"I do not of course mean that the words 'Thy will be done' are merely a submission. They should, and if we make progress they will increasingly, be the voice of joyful desire, free of hunger and thirst, and I argue very heartily that to treat them simply as a clause of submission or renunciation greatly impoverished the prayer. But though they should be something far more and better than resigned or submissive, they must not be less; they must be that at least. And as such they necessarily discipline all the succeeding clauses."
