When we think of the height of God's infinity we should not despair of His compassion reaching us from such a height; and when we recall the infinite depth of our fall through sin we should not refuse to believe that the virtue which has been killed in us will rise again. For God can accomplish both these things: He can come down and illumine our intellect with spiritual knowledge, and He can raise up the virtue within us and exalt it with Himself through works of righteousness.
Maximus the ConfessorCreated man cannot become a son of God and god by grace through deification, unless he is first through his own free choice begotten in the Spirit by means of the self-loving and independent power dwelling naturally in him.
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 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.
Maximus the ConfessorIf God suffers in the flesh when He is made man, should we not rejoice when we suffer, for we have God to share our sufferings? This shared suffering confers the kingdom on us. For he spoke truly who said, 'If we suffer with Him, then we shall also be glorified with Him' (Rom. 8:17).
Maximus the ConfessorYou will be able to check envy if you rejoice with the man whom you envy whenever he rejoices, and grieve whenever he grieves.
Maximus the Confessor... for our sake loosing within Himself the bonds of bodily birth, He granted us through spiritual birth, according to our own volition, power to become children of God instead of children of flesh and blood if we have faith in His Name (cf. Jn. 1:12-13). For the Savior the sequence was, first of all, incarnation and bodily birth for my sake; and so thereupon the birth in the Spirit through baptism, originally spurned by Adam, for the sake of my salvation and restoration by grace, or, to describe it even more vividly, my very remaking.
