Humility and ascetic hardship free a man from all sin, for the one cuts out the passions of the soul, the other those of the body. This is what the blessed David indicates when he prays to God, saying, "Look on my humility and my toil, and forgive all my sins" (Ps. 25:18).
Maximus the ConfessorBefore His visible advent in the flesh the Logos of God dwelt among the patriarchs and prophets in a spiritual manner, prefiguring the mysteries of His advent. After His incarnation He is present in a similar way not only to those who are still beginners, nourishing them spiritually and leading them toward the maturity of divine perfection, but also to the perfect, secretly pre-delineating in them the features of His future advent as if in an ikon.
Maximus the ConfessorIf we keep the path of virtue undefiled through devout and true knowledge, and do not deviate to either side, we will experience the advent of God revealed to us because of our dispassion. For 'I will sing a psalm and in a pure path I will understand when Thou wilt come to me' (cf. Ps. 101:1-2). The psalm stands for virtuous conduct; understanding indicates the spiritual knowledge, gained through virtue, by means of which we perceive God's advent, when we wait for the Lord vigilant in the virtues.
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).
