When a man walks the straight path, he does not have a cross. But when he begins to step away from one side to another, then various circumstances arise that push him back onto a right path. These pushes comprise a man's cross. They vary, of course, according to what each individual needs.
A man who falls into sin is different from the way he was created. He is different, because he changes by his own actions the way he was meant to be. Man renounces himself when he becomes a different person through repentance. He leaves a corrupted man, which he had become through sin, and becomes such as he once was created, through mercy.
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.
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.
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.'
Once two brethren came to a certain elder whose custom it was not to eat every day. But when he saw the brethren he invited them with joy to dine with him, saying: Fasting has its reward, but he who eats out of charity fulfills two commandments, for he sets aside his own will and he refreshes his hungry brethren.
A certain priest, an unfortunate man who had no knowledge of divine experience like that of St. Silouan, said to another person, 'I wonder why they go to him, he does not read anything.' The other replied, 'He does not read anything, but he practices everything, unlike those who read a lot but do not do a thing.'
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.”
People have to answer greatly for not keeping the rules of the Church with respect to the fasts. People justify themselves by saying that they never considered it a sin to eat dairy products during the fasts. They repent and consider themselves sinners in every other respect, but they do not think to repent about not keeping the fasts. Meanwhile, they are transgressing the commandment of our holy Mother, the Church, and according to the teaching of the Apostle Paul, they are as the heathen and publicans because of their disobedience.
Compunction comes when you consider how much you have grieved God Who is so good, so sweet, so merciful, so kind, and entirely full of love; Who was crucified and suffered everything for us. When you meditate on these things and other things the Lord has suffered, they bring compunction.
