Created 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 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 ConfessorLet us be satisfied simply with what sustains our present life, not with what pampers it. Let us pray to God for this, as we have been taught, so that we may keep our souls unenslaved and absolutely free from domination by any of the visible things loved for the sake of the body. Let us show that we eat for the sake of living, and not be guilty of living for the sake of eating. The first is a sign of intelligence, the second proof of its absence.
Maximus the ConfessorWhen what has been created in time according to the temporal order has reached maturity, it ceases from natural growth. But when what has been brought about by the knowledge of God through the practice of the virtues has reached maturity, it starts to grow anew. For the end of one stage constitutes the starting point of the next.
