48. Yet do not think that we fall into fantasies or other passions at God’s will. God allows this to happen because of our negligence, and in His loving kindness and for our salvation, leads us to humility by means of the evil (which manifests itself in us). So learn what you are like and humble yourself, not only before God but also before men, and put all your cares in Him Who can do infinitely more than we ask for or can think of.
