Do not be surprised at what I have written above, and do not doubt the truth of the fact that a man can restore sight by prayer, or heal every manner of illness and infirmity. Consider the saints' way of life. It was not that of ordinary men. Their endurance was like that of the bodiless angels themselves. Their food was bread and water, and they ate little and seldom. One of them would eat after a day, another after two, another once a week, another once in two weeks, another would eat nothing for forty days and another would not even eat bread, but only herbs and roots. Thy did not care about their clothing, either. Barefoot and poorly clad, they endured the burning heat of the sun and the freezing cold of winter, wandering the earth, over wood and rock. Likewise, they prayed to God constantly and unceasingly, day and night. They would stand like immovable pillers; if they rested upon the ground, it was only for a little while. Such was the faith of the saints and their love for God.
