As a general rule, decide whether a thing is permissible by the effect it produces within. Permit yourself what is constructive, but never what is destructive.
If the main goal of the repentant sinner should be total, light-bearing and blessed communion with God, then the main hindrance to this is the existence of the passions still active and working in him - the virtues being as yet unsealed in him - and the unrighteousness of his powers. Therefore his main work upon conversion and repentance should be the uprooting of the passions and sealing the virtues - in a word, correcting himself.
For while the body is bowed to the ground the mouth babbles idly, and the mind wanders here and there through the house, through the market place, how can such a person say he has prayed before the face of God? He prays before the face of the Lord who contains his soul in every direction, and withdraws it from all that is earthly, and, thrusting aside every human reflection, raises it up towards heaven.
Do not the angels differ from us in this respect, that they do not want so many things as we do? Therefore the less we need, the more we are on our way to them; the more we need, the more we sink down to this perishable life.
Our inner lives never get put into the proper order all of a sudden. What is always required and what lies ahead is intensified labor over oneself, over one's inner self, by the assimilation of good intention and by the enabling of grace through the Mysteries. This labor and effort is directed toward destroying the disorder that reigns inside, in its place it establishes order and harmony, after which follows inner peace and a continual joyful mood of the heart.
The origin of the Christian life is in arousal by grace. A person who has heeded this arousal is not then deprived of guidance by grace and communion with it at all times, as it persists through proper attention to it.
When an archer desires to shoot his arrows successfully, he first takes great pains over his posture and aligns himself accurately with his mark. It should be the same for you who are about to shoot the head of the wicked devil. Let us be concerned first for the good order of sensations and then for the good posture of inner thoughts.
Brethren, let us also occupy yourselves with noetic prayer… and seeking God’s mercy, cry out with a humble heart from morning till night and if possible all night long, saying constantly: 'Lord Jesus Christ, Son of God, have mercy on us.'
Each one, in undertaking any task, should have this purpose in mind: to serve the need of others, not his own ends. In this way he will escape the charge of self-love, and will receive a blessing for his fraternal love from the Lord Who said: As long as you did it to one of these my least brethren, you did it to me (Mt. 25:40).
This reading with prayer preceding strengthens the soul and gives it strength for the entire day. Doctors say you should not leave the house on an empty stomach. With respect to the soul, this is fulfilled by morning prayer and reading. The soul is fed by them, and sets out on the business of the day nourished.
He that wears the purple, laying aside his pomp, stands begging of the saints to be his patrons with God; and he that wears the diadem begs the Tent-maker and the Fisherman as patrons, even though they be dead.
You have the book of discourses by St. Macarius of Egypt. Kindly read the 19th discourse, concerning a Christian's duty to force himself to do good. There it is written, 'One must force oneself to pray, even if one has no spiritual prayer.' And, 'In such a case, God, seeing that a man earnestly is striving, pushing himself against the will of his heart (that is, his thoughts), He grants him true prayer.' By true prayer, St. Macarius means the undistracted, collected, deep prayer that occurs when the mind stands unswervingly before God. As the mind begins to stand firmly before God, it discovers such sweetness, that it wishes to remain in true prayer forever, desiring nothing more.
Since the enemy watches you constantly, waiting for an opportunity to sow evil in you, be doubly watchful over yourself, lest you fall in the nets spread for you. As soon as he shows you some fault in your neighbor, hasten to repel this thought, lest it take root in you and grow. Cast it out, so that no trace is left in you, and replace it by the thought of the good qualities you know your neighbor to possess, or of those people generally should have. If you still feel the impulse to pass judgment, add to this the truth that you are given no authority for this and that the moment you assume this authority you thereby make yourself worthy of judgment and condemnation, not before powerless men, but before God, the all-powerful Judge of all.
Receive me today, O Son of God, as a partaker of Thy mystical Supper; for I shall not speak of Thy mystery to Thine enemies, neither give Thee a kiss as did Judas. But like a thief, I shall confess Thee. Remember me, O Lord, when Thou comest into Thy kingdom.
But let us speak that which is good, to the edification of faith. That is, to speak only what will help to build up our neighbor in virtue; nothing more than that.
For, just as it is good to recall one's sins, so it is also good to forget one's good deeds. Why is this? Because remembrance of our good deeds puffs us up with arrogance, whereas remembrance of our sins curbs and humbles our mind; the former makes us more sluggish, but the latter makes us more diligent. Indeed, those who do not think that they have anything good become more eager to acquire what is good, whereas those who reckon that they have stored up a great deal of merchandise, confident they have an abundance of this, do not display much zeal for obtaining more of it.
