The field of spiritual combat
At every moment of life the human soul is the field of combat between God and Satan. So it is essential that the soul allows free access to the Lord so that he can strengthen it on every side and with all kinds of weapons. Thus his light will be able to enlighten it so as to fight better against the darkness of error. Clothed with Christ (Gal 3:27), with his truth and righteousness, protected by the shield of faith and the word of God, it will overcome its enemies however strong they may be (Eph 6:13f.). Even so, however, to be clothed with Christ we must die to ourselves.
