...the Lord said as He drew near His passion, 'Now is the Son of man glorified, and God is glorified in Him. If God is glorified in Him, God will also glorify Him in Himself; and He will glorify Him at once' (Jn. 13:31-32). From This it is clear that divine gifts follow sufferings endured for the sake of virtue.
Maximus the ConfessorTo harbor no envy, no anger, no resentment against an offender is still not to have charity for him. It is possible, without any charity, to avoid rendering evil for evil. But to render, spontaneously, good for evil - such belongs to a perfect spiritual love.
Maximus the ConfessorIf you are remembering evil against someone, then pray for him; and as you remove through prayer the pain of the remembrance of the evil he has done, you will stop the advance of the passion. And when you have attained brotherly love and love for mankind, you will completely cast this passion out of your soul. Then when someone else does evil to you, be affectionate and humble toward him, and treat him kindly, and you will deliver him from this passion.
Maximus the ConfessorDo not disdain the commandment to love, for through it you become a son of God, and when you break it, you become a son of Gehenna.
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 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.
