The field of battle between God and Satan is the human soul. It is in the soul that the battle rages every moment of life. The soul must give free access to the Lord so that it be fortified by him in every respect and with all kinds of weapons; that his light may enlighten it to combat the darkness of error; that it be clothed with Jesus Christ, with his justice, truth, the shield of faith, the word of God, in order to conquer such powerful enemies. To be clothed with Jesus Christ it is necessary to die to oneself.
– Saint Padre Pio
