Do 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.
Maximus the ConfessorThe man who has struggled bravely with the passions of the body, has fought ably against unclean spirits, and has expelled from his soul the conceptual images they provoke, should pray for a pure heart to be given him and for a spirit of integrity to be renewed within him (cf. Ps. 51:10). In other words, he should pray that by grace he may be completely emptied of evil thoughts and filled with divine thoughts, so that he may become a spiritual world of God, splendid and vast, wrought from moral, natural and theological forms of contemplation.
Maximus the ConfessorSome passions are bodily, other spiritual. Bodily passions have their sources in the body, while spiritual ones come from external things. But love and temperance cut out both the one and the other: Love cuts out spiritual passions, and temperance bodily ones.
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.
Maximus the ConfessorHe who is a beginner on the way must not be brought to practise the commandments by kindness alone, but must more often be induced to continue the struggle by being rigorously reminded of God's judgment. In this way he will not only be moved by love to desire what is divine, but will be moved by fear to avoid what is evil. For 'I will sing to Thee, O Lord, of mercy and judgment' (Ps. 101:1 LXX). He will sing to God charmed by love, and steeled by fear he will have strength for the song.
