The patient endurance of the saints exhausts the evil power that attacks them, since it makes them glory in sufferings undergone for the sake of the truth. It teaches those too much concerned with a life in the flesh to deepen themselves through such sufferings instead of pursuing ease and comfort; and it makes the flesh's natural weakness in the endurance of suffering a foundation for overwhelming spiritual power. For the natural weakness of the saints is precisely such a foundation, since the Lord has made their weakness stronger than the proud devil.
Maximus the ConfessorSome passions are bodily, other spiritual. Bodily passions have their sources in the body, while spiritual ones come from external things. But love and temperance cut out both the one and the other: Love cuts out spiritual passions, and temperance bodily ones.
Maximus the Confessor'The long-suffering man abounds in understanding' (Prov. 14:29), because he endures everything to the end and, while awaiting that end, patiently bears his distress. The end, as St. Paul says, is everlasting life (cf. Rom. 6:22). 'And this is eternal life, that they might know You the only true God, and Jesus Christ whom You have sent' (Jn. 17:3).
Maximus the ConfessorWhen we think of the height of God's infinity we should not despair of His compassion reaching us from such a height; and when we recall the infinite depth of our fall through sin we should not refuse to believe that the virtue which has been killed in us will rise again. For God can accomplish both these things: He can come down and illumine our intellect with spiritual knowledge, and He can raise up the virtue within us and exalt it with Himself through works of righteousness.
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 ConfessorA man who has been assiduous in acquiring the fruits of love will not cease loving even if he suffers a thousand calamities. Let Stephen, the disciple of Christ, and others like him persuade you of the truth of this (cf. Acts 7:60). Our Lord Himself prayed for His murderers and asked the Father to forgive them because they did not know what they were doing (cf. Luke 23:34).
