A Christian receives divine wisdom in three ways: by the commandments, teachings, and faith. The commandments free the mind from passions. Teachings lead it to true knowledge of nature. Faith leads to the contemplation of the Holy Trinity.
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.
Maximus the ConfessorHe who devoutly strives to attain wisdom and is on his guard against the invisible powers, should pray that both natural discrimination - whose light is but limited - and the illuminating grace of the Spirit abide in him. The first by means of practice trains the flesh in virtue, the second illuminates the intellect so that it chooses above all else companionship with wisdom; and through wisdom it destroys the strongholds of evil and pulls down 'all the self-esteem that exalts itself against the knowledge of God' (II Cor. 10:5).
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.
