Our enemies (demons) fell because of their pride, and call us to follow them, and bring us feelings of praise. And if your soul accepts that praise, then grace will depart, until the soul becomes humble again. And so all your life you must learn the humility of Christ.
Abba Theon ate vegetables, but only those that did not need to be cooked. They say that he used to go out of his cell at night and stay in the company of the wild animals, giving them drink from the water he had. Certainly one could see the tracks of antelopes and wild asses and gazelles and other animals near his hermitage. These creatures always gave him pleasure.
The more wood you pile on a fire the more heat you get, and thus it is with God - the more you think on Him the more you are fired with love and fervor towards Him. He who loves the Lord is always mindful of Him, and remembrance of God begets prayer.
The Lord commands all men to repent (Matt. 4:17), so that even the spiritual and those making progress should not neglect this injunction and fail to give attention to the smallest and most subtle errors.
Train yourself to cut off an intrusive thought immediately…Be at pains over this, so that you acquire the habit. The soul is a creature of habit: according to the habit you have acquired, so will you act all the rest of your life.
It was said of Abba Mark the Egyptian that he lived for thirty years without going out of his cell. The priest used to take Holy Communion to him. But the devil, seeing the remarkable endurance of this man, decided to tempt him, by making him blame the priest. He brought it about that a demoniac went to the old man, under the pretext of asking for prayers. Before anything was said, the possessed man cried out to the old man, 'Your priest smells of sin, do not let him come near you any more.' But Mark, filled with the spirit of God, said to him, 'My son, everyone rids himself of impurity, but you bring it. It is written: ‘Judge not for that you be not judged.’ (Matt. 7:1) However, even if he is a sinner, the Lord will save him, for it is written: ‘Pray for one another that you may be healed.’' (James 5:16) When he had said this and when he had prayed, he drove the devil out of the man and sent him away healed. When the priest came, according to his custom, the old man received him with joy. Seeing the absence of malice in the old man, the good God showed him a marvel. When the priest prepared himself to stand before the holy table, this is what the old man related: 'I saw the angel of the Lord descent from heaven and place his hand on the priest’s head and he became like a pillar of fire. I was filled with wonder at this sight, and I heard a voice saying to me, ‘Man, why are you astonished at this? In truth, if an earthly king does not allow his nobles to stand in his presence in soiled garments, but only arrayed in glory, how much more will the divine power purify the servants of the holy mysteries who stand before the heavenly glory?’' And the noble athlete of Christ, Mark the Egyptian, became great and was judged worthy of this grace because he had not judged the priest.
Obedience is necessary not only for monks, but for all people. Even the Lord was obedient. Proud and self-assured do not let grace reside within them, and therefore they never have internal peace, whereas the soul of the obedient easily accepts the grace of the Holy Spirit, bringing with it joy and serenity.
A brother asked Abba Isidore the priest, 'Why are the demons so frightened of you?' The old man said to him, 'Because, ever since the day I began practicing ascesis, I have striven to prevent anger from reaching my lips.'
When tested by some trial you should try to find out not why or through whom it came, but only how to endure it gratefully, without distress or rancor.
Fasting needn't be limited to abstinence from food alone, because true fasting is departure from evil deeds. Forgive your neighbor any insult, abstain from causing your neighbor offence, abstain from irritation, from senseless sorrows, from fear, wrath, and so on. ‘True fasting is alienation from evil, temperance of the tongue, setting aside of wrath, casting out of lust, idle talk, lies, and oath-breaking’…This is a true and pleasing fast for the Lord. Departing from these vices and from a corrupt state is what comprises a true fast.
Concerning fasting, do not grieve, as I have said to you before: God does not demand of anyone labors beyond his strength. And indeed, what is fasting if not a punishment of the body in order to humble a healthy body and make it infirm for passions, according to the word of the Apostle: 'When I am weak, then am I strong' (II Corinthians 12:10).
Train yourself to cut off an intrusive thought immediately… Be at pains over this, so that you acquire the habit. The soul is a creature of habit: according to the habit you have acquired, so will you act all the rest of your life.
Watch constantly, learning to understand God's law, for this warms the heart with heavenly fire. Guard your lips from the idle word, or empty talk, lest the heart gets used to evil words.
To many people the Saints seem far from us. But the Saints are far only from those who have taken themselves away from them, and are very close to those who keep Christ’s commandments and possess the grace of the Holy Spirit.
