By St. Isaac the Syrian
The Savior began the work of our salvation with fasting. In the same way, all those who follow in the footsteps of the Savior build on this foundation the beginning of their endeavor, since fasting is a weapon established by God. Who will escape blame if he neglects this? If the Lawgiver Himself fasts, how can any of those who have to obey the law be exempt from fasting? This is why the human race knew no victory before fasting, and the devil was never defeated by our nature as it is: but this weapon has indeed deprived the devil of strength from the outset.
Our Lord was the Leader and the first example of this victory, in order to place the first crown of victory on the head of our nature. As soon as the devil sees someone possessed of this weapon, fear straightway falls on this adversary and tormentor of ours, who remembers and thinks of his defeat by the Savior in the wilderness; his strength is at once destroyed and the sight of the weapon given us by our Supreme Leader burns him up. A man armed with the weapon of fasting is always afire with zeal. He who remains therein, keeps his mind steadfast and ready to meet and repel all violent passions.
