No benefit comes from a just man's prayer if he who asks for it finds more pleasure in sin than in virtue. For Samuel mourned over Saul when he sinned, but he was not able to obtain God's mercy, for his grief was not supported by the necessary change of life on the part of the sinner. Hence God put an end to the pointless grief of His servant, saying to him, 'How long will you mourn for Saul, seeing I have rejected him from reigning over Israel?' (I Sam. 16:1).
Maximus the ConfessorAs long as I remain imperfect and refractory, neither obeying God by practising the commandments nor becoming perfect in spiritual knowledge, Christ from my point of view also appears imperfect and refractory because of me. For I diminish and cripple Him by not growing in spirit with Him, since I am 'the body of Christ and one of its members' (I Cor. 12:27).
Maximus the ConfessorA man who has been assiduous in acquiring the fruits of love will not cease loving even if he suffers a thousand calamities. Let Stephen, the disciple of Christ, and others like him persuade you of the truth of this (cf. Acts 7:60). Our Lord Himself prayed for His murderers and asked the Father to forgive them because they did not know what they were doing (cf. Luke 23:34).
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.
Maximus the ConfessorWhen 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 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.
