Confirm yourself in this truth: that every Divine writing that is in agreement with the path of salvation instructs, teaches, chastises, and strengthens, that our path might be ever according to God.
Truly wretched and three times miserable is the soul that has left the world and dedicated itself to God but has not lived in a manner worthy of its promise. Then, brothers, let us not allow this age, which is short and contemptible and passes like a shadow, to steal that blessed and immortal life away from us.
No matter what misfortune might befall you, no matter what unpleasantness might occur, say 'I will endure this for Jesus Christ's sake!' Just say that, and you will feel better, for the Name of Jesus Christ is powerful. Before It, all difficulties abate, and demons disappear. Your annoyance and faintness of heart will abate when you repeat His most sweet Name. Lord, grant unto me to see my transgressions. Lord, grant unto me patience, magnanimity, and meekness.
One must train oneself in self-reproach, that is, always accuse oneself & not others in one’s mind, reproach oneself and not others, and with a severe distrust of oneself accuse oneself of the failings which are covered up by our self-love, accuse ourself of our inclinations to sin. He who has self-reproach has peace, writes Abba Dorotheos, & will never be disturbed. If to such a one there should occur an illness, a wrong, a vexation, or some similar misfortune, he ascribes everything to his own sins & thanks God. If such a one is punished or reprimanded by the superior, he accepts all this as good & accepts every severe word against himself without murmuring or talking back, as the judgment of God.
When someone is beginning the spiritual life, he should not study a lot, but instead watch himself and guard his thoughts. A strong person is the one who chews well, not the one who eats a lot.
No Christian believing rightly in God should ever be off his guard. He should always be on the look-out for temptation, so that when it comes he will not be surprised or disturbed, but will gladly endure the toil and affliction it causes, and so will understand what he is saying when he chants with the prophet: 'Prove me, O Lord, and try me' (Ps. 26:2 LXX). For the prophet did not say, 'Thy correction has destroyed me,' but, 'it has upheld me to the end' (Ps. 18:35 LXX).
Peace of soul is acquired by perfect surrender to the Divine Will, without which nothing happens... He, in whose heart humility and meekness are reborn, will find true rest for his soul. He will be satisfied with everything, grateful for everything, peaceful and full of love for everybody. He will judge none and will feel no anger. His heart will be filled with divine sweetness, that is, he will feel in himself the Kingdom of God because God grants His grace only to the humble.
Beguiling and deceptive is the life of the world, fruitless its labor, perilous its delight, poor its riches, delusive its honors, inconstant, insignificant; and woe to those who hope in its seeming goods: because of this many die without repentance. Blessed and most blessed are those who depart from the world and its desires.
One must train oneself in generous patience, so as to endure without complaint all that happens to us. We will possess patience when we accept everything that happens to us, both what is joyful and what is sad, without distinction, as from the hand of God.
If you love Christ God, then endure as He endured, and do all that is pleasing to Him. He taught and did. Unfailingly your love should be such as does good, endures, is disturbed by nothing present, and in everything ever thanks Him not with words and tongue, but with very deeds.
Do not be ashamed to reveal your scabs to your spiritual director. Be prepared as well to accept from him disgrace for your sins, so that by being disgraced, you might avoid eternal shame.
In times of any sorrow, illness, poverty, need, disagreements, and any difficulty, it is better to spend less time in ruminating and talking to ourselves, and more often to turn to Christ our God and to his most pure Mother in prayer, even if it is only a brief one. Through that, the spirit of bitter despondency will be driven away, and the heart will be filled with joy and with hope in God.
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.
The drunkard, the fornicator, the proud - he will receive God's mercy. But he who does not want to forgive, to excuse, to justify consciously, intentionally... that person closes himself to eternal life before God, and even more so in the present life. He is turned away and not heard.
In patience is the assembly of all the virtues by which our souls are saved, as St. Ephraim says: He who acquires patience touches on every virtue; for he rejoices in sorrows, is well tested in misfortunes, is glad in perils, is ready for obedience, is filled with love, gives praise when provoked, is humble when reproached, is unwavering in misfortunes.
