Sin, to one who loves God, is nothing other than an arrow from the enemy in battle. The true Christian is a warrior fighting his way through the regiments of the unseen enemy to his heavenly homeland.
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.
Labor to acquire meekness. Concerning the heavenly virtues, meekness and humility, the Lord Himself teaches us, saying: Learn of Me, for I am meek and humble in heart; and ye shall find rest unto your souls (Matt. 11:29). Learn not from angels, nor from men, but from Me, He says; that is, from the higher wisdom.
The Fathers used to say, “If temptation befall thee in the place thou dost inhabit, desert not the place in the time of temptation: for if thou dost, wheresoever thou goest, thou shalt find what thou fliest before thee.”
I suppose that it is sometimes better to fall oneself and rise, than to judge one's neighbor; because one who has sinned is incited to self-abasement and repentance, while he who judges one who has sinned becomes hardened in an illusion about himself and in pride. Therefore everyone must guard himself, as much as possible, so as not to judge.
He who knows himself pays no heed to the sins of others, but looks at his own and is always repenting over them; he reflects concerning himself, and condemns himself, and does not interfere in anything apart from his own position.
We came from Palestine to Egypt and went to see one of the fathers. He offered us hospitality and we said, 'Why do you not keep the fast when visitors come to see you? In Palestine they keep it.' He replied, 'Fasting is always with me but I cannot always have you here. It is useful and necessary to fast, but we choose whether we will fast or not. What God commands is perfect love. I receive Christ in you and so I must do everything possible to serve you with love. When I have sent you on your way, then I can continue my rule of fasting. The sons of the bridegroom cannot fast while the bridegroom is with them; when he is taken away from them, then they will fast.'
Even a pious person is not immune to spiritual sickness if he does not have a wise guide -- either a living person or a spiritual writer. This sickness is called prelest, or spiritual delusion, imagining oneself to be near to God and to the realm of the divine and supernatural. Even zealous ascetics in monasteries are sometimes subject to this delusion, but of course, laymen who are zealous in external struggles (podvigi) undergo it much more frequently. Surpassing their acquaintances in struggles of prayer and fasting, they imagine that they are seers of divine visions, or at least of dreams inspired by grace. In every event of their lives, they see special intentional directions from God or their guardian angel. And then they start imagining that they are God's elect, and often try to foretell the future. The Holy Fathers armed themselves against nothing so fiercely as against this sickness -- prelest.
A certain brother asked the Abbot Poemen, saying, 'What am I to do, Father, for I am troubled in sadness?' The old man said to him, 'Look to no man for aught, condemn no man, disparage no man: and God shall give thee rest.'
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.
The good Physician calls me and demands no payment, nor does he spill my blood. But my slothfulness prevents me from going to Him. He comes Himself to heal me, but always finds me engaged in acts that prevent His remedies from rendering me their healing power.
The vain desires of this world separate us from our homeland; love of them and habit clothe our soul as if in a hideous garment. We, traveling on the journey of this life and calling on God to help us, ought to be divesting ourselves of this hideous garment and clothing ourselves in new desires, in a new love of the age to come, and thereby to receive knowledge of how near or how far we are from our heavenly homeland. But it is not possible to do this quickly; rather one must follow the example of sick people, who, wishing the desired (health), do not leave off seeking means to cure themselves.
