Without the power of intelligence there is no capacity for spiritual knowledge; and without spiritual knowledge we cannot have the faith from which springs that hope whereby we grasp things of the future as though they were present. Without the power of desire there is no longing, and so no love, which is the issue of longing; for the property of desire is to love something. And without the incensive power, intensifying the desire for union with what is loved, there can be no peace, for peace is truly the complete and undisturbed possession of what is desired.
Maximus the ConfessorNo 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 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 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 ConfessorThe person who loves God cannot help loving every man as himself, even though he is grieved by the passions of those who are not yet purified. But when they amend their lives, his delight is indescribable and knows no bounds. A soul filled with thoughts of sensual desire and hatred is unpurified. If we detect any trace of hatred in our hearts against any man whatsoever for committing any fault, we are utterly estranged from love for God, since love for God absolutely precludes us from hating any man.
