He 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).

Theology without practice is the theology of demons

Trials are sent to some so as to take away past sins, to others so as to eradicate sins now being committed, and to yet others so as to forestall sins which may be committed in the future. These are distinct from the trials that arise in order to test men in the way that Job was tested.

If you make provision for the desires of the flesh and bear a grudge against your neighbor on account of something transitory, you worship the creature instead of the Creator.

The man who has struggled bravely with the passions of the body, has fought ably against unclean spirits, and has expelled from his soul the conceptual images they provoke, should pray for a pure heart to be given him and for a spirit of integrity to be renewed within him (cf. Ps. 51:10). In other words, he should pray that by grace he may be completely emptied of evil thoughts and filled with divine thoughts, so that he may become a spiritual world of God, splendid and vast, wrought from moral, natural and theological forms of contemplation.

He 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).

As 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).
