Fasting is a good teacher: (1) It soon makes everybody who fasts understand that a man requires very little food and drink, and that in general we are greedy and eat a great deal more than is necessary—that is, than our nature requires. (2) Fasting clearly shows or discloses all the infirmities of our soul, all its weaknesses, deficiencies, sins, and passions; just as when muddy, standing water is beginning to be cleaned it shows what reptiles and what sort of dirt it contains. (3) It shows us all the necessity of turning to God with the whole heart, and of seeking His mercy, help, and salvation. (4) Fasting shows all the craftiness, cunning, and malice of the bodiless spirits, whom we have hitherto unwittingly served, and whose cunning, now that we are enlightened by the light of God's grace, becomes clear, and who now maliciously persecute us for having left their ways.
St. John of Kronstadt, from My Life in Christ
"We forgive them that trespass against us." This means not to feel against our neighbour who has been guilty towards us (intentionally, obstinately, or unintentionally) any vexation, enmity, or malice, but to forgive him his fault in all simplicity of heart, vividly representing to ourselves our own infirmities and falling into sin, and maintaining towards our guilty neighbour the same love and the same feelings of kindness which we felt towards him before his fault. What would it be if the Lord were to notice our iniquities as we do the faults of our neighbour? Who could withstand? But as the Lord is long-suffering and merciful, be also long-suffering and merciful (not strictly exacting, but compassionate). "Charity suffereth long, and is kind." [1 Corinthian 13:4] Do not reckon the faults of your neighbour, consider them as though they were not; as nothing! We are one body, and his body is a sinful one. What is more common and easier to us than sins? We breathe them like air. But the Lord, the Head of the body of the Church, is the cleansing of them. Leave everything to the Head, Who worketh all things in all; and hold fast to love alone, for it is the only infallible thing in our life (pure love). Do not serve the Devil by the spirit of enmity, malice, hatred; do not increase evil by evil, and do not spread the kingdom of the enemy in the kingdom of Christ." Overcome evil with good." [Romans 12:21] For you cannot conquer evil with evil, just as you cannot put out fire by fire, but only by water. Malice is always an imagination of the Devil. Love is always God's truth and God's child.

From My Life in Christ
When you walk in a forest, garden, or meadow, and see the young shoots of the plants, the fruits on the trees, and the variety of the flowers of the field, learn a lesson from God’s plants--namely, the lesson that every tree each summer unfailingly puts forth at least one shoot of considerable size, and unfailingly grows in height and dimensions. It seems as though every tree endeavors each year to advance by the strength that God has given it; therefore, say to yourself, I, too, must each day, each year, absolutely grow higher and higher morally, better and better, more and more perfect; must advance on the road to the Kingdom of Heaven, or to the Father which is in Heaven, through the strength of our Lord Jesus Christ and His Spirit dwelling and working within me. As the field is adorned by a multitude of flowers, so should the field of my own soul be adorned by all the flowers of virtue; as the trees bring forth flowers and afterwards fruit, so must my soul bring forth the fruits of faith and good works.
We must love our neighbour still more when he sins against God, or against ourselves, because then he is sick, because then he is in spiritual misfortune, in danger; then, especially, we must have compassion upon him, pray for him, and apply to his heart a healing plaster--a word of kindness, instruction, reproval, consolation, forgiveness, love. "Forgiving one another, even as God, for Christ's sake hath forgiven you."  All sins and passions, quarrels and disputes, are truly spiritual diseases; that is how we must look upon them. Or, all passions are a fire of the soul, a great fire, raging inwardly; a fire proceeding from the abyss of hell. It must be extinguished by the water of love, which is strong enough to extinguish every infernal flame of malice and of other passions. But woe and misfortune to us, to our self-love, if we increase this flame by a fresh infernal flame, by our own malice and irritability, and thus make ourselves the assistants of the spirits of evil, ever endeavouring to inflame the souls of men by means of many and various passions. If we do so, we ourselves shall deserve the fire of Gehenna; and if we do not repent, and do not become in future wise unto good and simple unto evil, then we shall be condemned, together with the Devil and his angels, to torments in the lake of fire. Therefore, do not let us be overcome of evil, but let us overcome evil with good. How accursed are we men! How is it that we have not yet learned to consider every sin as a great misfortune for our soul, and not to pity, heartily, sincerely, lovingly, those who fall into such a misfortune. Why do we not flee from it as from poison, as from a serpent? Why do we linger in it? Why have we no pity upon ourselves, too, when we are subjected to any sin?

from My Life in Christ
When God looks mercifully upon earth-born creatures through the eyes of nature, through the eyes of bright, healthful weather, everyone feels bright and joyful. When there is a healthful breeze, there is wholesome air in all bodies and souls; but when a cold, damp, strong wind blows, then everyone feels oppressed in soul and body. Many earth-born creatures groan from maladies; many give themselves up to despondency and melancholy. So powerful and irresistible is the influence of nature upon mankind. And it is remarkable that those who are less bound by carnal desires and sweetnesses; who are less given up to gluttony; who are more moderate in eating and drinking, to them nature is more kindly disposed, and does not oppress them--at least, not nearly so much as those who are the slaves of their nature and their flesh. O how clear it is that our life is in the Lord, and not in sensual things; how clear it is that the Lord is in everything "which worketh all in all."

If you wish to ask of God in prayer any blessing for yourself, then before praying prepare yourself for undoubting and firm faith, and take in good time means against doubt and unbelief. For it will go ill with you if during the prayer itself your heart wavers in its faith and does not stand firm in it; then do not even expect to obtain of the Lord what you have prayed for doubtingly, for in so doing you have offended the Lord, and God does not bestow His gifts upon a reviler. "And all things, whatsoever ye shall ask in prayer, believing, ye shall receive,"  said the Lord. This means, that if you doubt and do not believe, you shall not receive. "If ye have faith and doubt not," said He also, "ye shall have power to move mountains." 
Therefore, if you doubt and do not believe, you shall not have power to do so. "Let him ask in faith, nothing wavering, for he that wavereth is like a wave of the sea driven with the wind and tossed," says the Apostle James; "for let not that man think he shall receive anything of the Lord. A double-minded man is unstable in all his ways."
