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 ConfessorWhen a man's intellect is constantly with God, his desire grows beyond all measure into an intense longing for God and his incensiveness is completely transformed into divine love. For by continual participation in the divine radiance his intellect becomes totally filled with light; and when it has reintegrated its passible aspect, it redirects this aspect towards God, filling it with an incomprehensible and intense longing for Him and with unceasing love, thus drawing it entirely away from worldly things to the divine.
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 ConfessorDispassion and humility lead to spiritual knowledge. Without them no one will see the Lord.
Maximus the ConfessorWhen you are insulted by someone or humiliated, guard against angry thoughts, lest they arouse a feeling of irritation, and so cut you off from love and place you in the realm of hatred. You should know that you have been greatly benefited when you have suffered deeply because of some insult or indignity; for by means of the indignity self-esteem has been driven out of you.
Maximus the ConfessorIf the words of God are uttered merely as verbal expressions, and their message is not rooted in the virtuous way of life of those who utter them, they will not be heard. But if they are uttered through the practice of the commandments, their sound has such power that they dissolve the demons and dispose men eagerly to build their hearts into temples of God through making progress in works of righteousness.
