He who devoutly strives to attain wisdom and is on his guard against the invisible powers, should pray that both natural discrimination - whose light is but limited - and the illuminating grace of the Spirit abide in him. The first by means of practice trains the flesh in virtue, the second illuminates the intellect so that it chooses above all else companionship with wisdom; and through wisdom it destroys the strongholds of evil and pulls down 'all the self-esteem that exalts itself against the knowledge of God' (II Cor. 10:5).
Maximus the ConfessorLet us be satisfied simply with what sustains our present life, not with what pampers it. Let us pray to God for this, as we have been taught, so that we may keep our souls unenslaved and absolutely free from domination by any of the visible things loved for the sake of the body. Let us show that we eat for the sake of living, and not be guilty of living for the sake of eating. The first is a sign of intelligence, the second proof of its absence.
Maximus the ConfessorOur forefather Adam... used his freedom to turn toward what was worse and to direct his desire away from what had been permitted to what was forbidden. It was in his power 'to be united to the Lord and become one spirit with God...' (I Cor. 6:15). But Adam was deceived and chose to cut himself off voluntarily from God's happy end for him, preferring by his own free choice to be drawn down to the earth (cf. Gen. 2:17) than to become God by grace.
Maximus the ConfessorUnclean spirits increase the passions in us, making use of our negligence, and inciting them. But the angels decrease our passions, inciting us to the perfection of virtue.
Maximus the ConfessorWhoever sees in himself the traces of hatred toward any man on account of any kind of sin is completely foreign to the love of God. For love toward God does not at all tolerate hatred for man.
Maximus the ConfessorDo not say that faith in Christ alone can save you, for this is not possible if you do not attain love for Him, which is demonstrated by deeds. As for mere faith: "The demons also believe and tremble" (James, 2:19). The action of love consists in heartfelt good deeds toward one's neighbor, magnanimity, patience, and sober use of things.
