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 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 ConfessorFood is not evil, but gluttony is. Childbearing is not evil, but fornication is. Money is not evil, but avarice is. Glory is not evil, but vainglory is. Indeed, there is no evil in existing things, but only in their misuse.
Maximus the ConfessorDispassion and humility lead to spiritual knowledge. Without them no one will see the Lord.
Maximus the ConfessorHumility and suffering free a man from all sin; for the first cuts out spiritual passions, and the latter bodily.
