If 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 ConfessorIf... Adam had trusted in God and been nourished from the tree of life (Gn. 2:9)? he would not have set aside the immortality that had been granted. For such immortality is eternally preserved by participation in life, since all life is genuine and preserved by appropriate food. The food of that blessed life is 'the bread that came down from heaven and gives life to the world' (Jn. 6:33), just as the inerrant Word Himself declares about Himself in the Gospels.
Maximus the ConfessorWhen a man's intellect is constantly with God, his desire grows beyond all measure into an intense longing for God and his incensiveness is completely transformed into divine love. For by continual participation in the divine radiance his intellect becomes totally filled with light; and when it has reintegrated its passible aspect, it redirects this aspect towards God, filling it with an incomprehensible and intense longing for Him and with unceasing love, thus drawing it entirely away from worldly things to the divine.
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.
