You see then, how much our Lord did, though seeming to do nothing: he rendered himself mean and despicable to all, as I have already said. And certainly I know no greater or more difficult practice in all the duties of life than this. And they, in my opinion, may be said to have reached the very summit of Christian perfection, who are so far advanced in it as to be able totally to overcome the arrogance of their flesh, and truly and unfeignedly to consent to be reputed as nothing, and even contemned as mean and insignificant.... Until you arrive to this point, never flatter yourself with having done anything.
