You yourself know that at all times the hope of comfort is wont to make men forget what is great, and good, and virtuous. Unless they resolve in their minds to suffer hardships, not even those who are found in this present world in the life of the flesh can attain the end of their desire. And since experience testifies to this, there is no need to prove it with words. For in every generation of those who have gone before us, even until now, it is this and nothing else that has made men feeble, so that they do not gain victories and are hindered from excellent deeds. Therefore, to sum up: no man disdains the Kingdom of the Heavens except in hope of some small comfort in this life.
