Man does not live for himself alone in this mortal body, in order to work on its account, but also for all men on earth; nay, he lives only for others, and not for himself. For it is to this end that he brings his own body into subjection, that he may be able to serve others more sincerely and more freely... Thus it is impossible that he should take his ease in this life, and not work for the good of his neighbors, since he must needs speak, act, and converse among men, just as Christ... had His conversation among men.
