Abba John the Dwarf said, "If a king wanted to take possession of his enemy's city, he would begin by cutting off the water and the food and so his enemies, dying of hunger, would submit to him. It is the same with the passions of the flesh; if a man goes about fasting and hungry the enemies of his soul grow weak."
The Sayings of the Desert Fathers
Our enemy has accomplished the amazing feat of poisoning and adulterating the food and water supply of the entire world. Yet, all things work together for good to those who love God...and our King is faithful to use the prowess of accomplished swordsmen (demons) to train us for spiritual battle.
