For Christians above all men are forbidden to correct the stumblings of sinners by force...it is necessary to make a man better not by force but by persuasion. We neither have authority granted us by law to restrain sinners, nor, if it were, should we know how to use it, since God gives the crown to those who are kept from evil, not by force, but by choice.
Prayer is a refuge for those who are shaken, an anchor for those tossed by waves, a walking stick for the infirm, a treasure house for the poor, a stronghold for the rich, a destroyer of sicknesses, a preserver of health. Prayer keeps our virtues intact and quickly removes all evil. If temptation overtakes us, it easily drives it away; if we lose some property or something else, which causes our soul grief, it removes it. Prayer banishes every sorrow, causes good humor, facilitates constant well-being. It is the mother of. love of wisdom. He who can sincerely pray is richer than everyone else, even though he is the poorest of all. On the contrary, he who does not have recourse to prayer, even though he sit on a king's throne, is the poorest of all...
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.
Having guarded ourselves against distractions and worries, let us turn our attention to our body on which mental vigilance is completely dependent. Human bodies differ widely from one another in strength and health. Some by their strength are like copper and iron; others are frail like grass. For this reason everyone should rule his body with great prudence, after exploring his physical powers. For a strong and healthy body, special fasts and vigils are suitable; they make it lighter, and give the mind a special wakefulness. A weak body should be strengthened by food and sleep according to one's physical needs, but on no account to satiety. Satiety is extremely harmful even for a weak body; it weakens it, and makes it susceptible to disease. Wise temperance of the stomach is a door to all the virtues. Restrain the stomach, and you will enter Paradise. But if you please and pamper your stomach, you will hurl yourself over the precipice of bodily impurity, into the fire of wrath and fury, you will coarsen and darken your mind, and in this way you will ruin your powers of attention and self-control, your sobriety and vigilance…
Even if we have thousands of acts of great virtue to our credit, our confidence in being heard must be based on God's mercy and His love for men. Even if we stand at the very summit of virtue, it is by mercy that we shall be saved.
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.
When day is done, let us give thanks both for what we have received throughout the day, and for what we have done rightly; and let us make confession of what we have not done, and of every sin, voluntary, or involuntary or even hidden from us, in word or in deed and even in our heart, that we may bring upon us God's mercy for all of them. For to examine ourselves upon what we have done is a great help against falling into the same sins again. The things you say in your hearts, be sorry for them upon your beds (Ps. iv. 5).
For the Antichrist will come for the destruction of men, and to injure them, for what will he not then work? He will change and confound all things, both by his commandments and by the fear of him. He will be terrible in every way: by his power and by his unlawful commandments.’
Prayer is a great good if offered up from a thankful soul; if we are steadfast in it, so that whether we receive or do not receive what we pray for we at all times give thanks to God. For since He will sometimes grant what we ask and sometimes will not, in both cases it is to our gain... For oftentimes God will delay, not as denying our prayer, but in His wisdom seeking rather for our perseverance, and desiring to draw us nearer to Himself; as a loving father when asked by his son for something will often do; withholding consent, and not from the will to refuse, but rather to encourage him in steadfastness.
According to the teachings of the Holy Fathers, in order to destroy insensibility man needs a constant, patient, uninterrupted activity against insensibility; he needs a constant, pious, and attentive life.
The Holy Fathers teach us how to become familiar with the Gospel, how to read it and how to understand it, what helps and what opposes its understanding. Therefore, at first you must devote more time to reading the Holy Fathers...
What does spoil repentance is being again entangled in the same evils. 'For there is one' we read, 'who builds, and one who pulls down, what have they gained more than toil? He who is dipped in water because of contact with a dead body, and then touches it again, what has he gained by his washing?' Even so if a man fasts because of his sins, and goes his way again, and does the same things, who will hear his prayer? And again we read 'if a man goes back from righteousness to sin the Lord will prepare him for the sword,' and, 'as a dog when he has returned to his vomit, and become odious, so is a fool who by his wickedness has returned to his sin.'
