...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 ConfessorInasmuch as you pray with all your soul for the one who has slandered you, so much will God reveal the truth to them who have believed the slander.
Maximus the ConfessorA soul that is nurtured by hatred toward man can not be at peace with God, Who has said: If you forgive not men their sins, neither shall your Father forgive your sins (Matt. 6:15). If a man does not want to be reconciled, you must at least guard yourself from hating, praying with a pure heart for him, and speaking no evil of him.
Maximus the ConfessorThe mind of a man that loves God does not fight against things or thoughts about them, but against the passions that are connected with these thoughts. That is, he does not struggle against a woman, or against one who has insulted him, and not against the images of them, but against the passions that are aroused by these images.
