Humility is the only virtue that no devil can imitate. If pride made demons out of angels, there is no doubt that humility could make angels out of demons.
John ClimacusRemembrance of Jesus' passion will heal your soul of resentment, by making it ashamed of itself when it remembers the patience of the Lord. Some people have wearied themselves and suffered for a long time in order to extract forgiveness. By far the best course, however, is to forget the offences, since the Lord says: "Forgive at once and you will be forgiven in generous measure." (cf. Luke 6:37-38)
John ClimacusThe man who pets a lion may tame it, but the man who coddles the body makes it ravenous.
