He who asks to receive his daily bread does not automatically receive it in its fullness as it is in itself: he receives it according to his own capacity as recipient. The Bread of Life (cf. Jn. 6:35) gives Himself in His love to all who ask, but not in the same way to all; for He gives Himself more fully to those who have performed great acts of righteousness, and in smaller measure to those who have not achieved so much. He gives Himself to each person according to that person's spiritual ability to receive Him.
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 ConfessorAs long as I remain imperfect and refractory, neither obeying God by practising the commandments nor becoming perfect in spiritual knowledge, Christ from my point of view also appears imperfect and refractory because of me. For I diminish and cripple Him by not growing in spirit with Him, since I am 'the body of Christ and one of its members' (I Cor. 12:27).
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.
