Saint Anthony of the Desert

"The devil is afraid of us when we pray and make sacrifices. He is also afraid when we are humble and good. He is especially afraid when we love Jesus very much. He runs away when we make the Sign of the Cross."

"The devil dreads fasting, prayer, humility, and good works: He is not able even to stop my mouth who speak against him. The illusions of the devil soon vanish, especially if a man arms himself with the Sign of the Cross. The devils tremble at the Sign of the Cross of our Lord, by which He triumphed over and disarmed them.
