Endurance is like an unshakeable rock in the winds and waves of life. However the tempest batters him, the patient man remains steadfast and does not turn back; and when he finds relief and joy, he is not carried away by self-glory: he is always the same, whether things are hard or easy, and for this reason, he is proof against the snares of the enemy.
To more conveniently become accustomed to remembering God, the fervent Christian has a special means, namely, to repeat ceaselessly a brief prayer of two or three words. Mostly this is 'Lord, have mercy.' or 'Lord Jesus Christ, Son of God, have mercy on me, a sinner.' If you have not yet heard of this, then hear it now, and if you have not done it, then begin from this hour to do it.
The day will come when you are toiling at self-observation and self-constraint, and the adversary will come up and mumble in your ear, 'This will all happen eventually. You’ve been working hard, now take it easy a little bit!' This is such a tempting suggestion that it does not immediately occur to you that you should counter it, or that it is so bad that however little you give in to it, it will cause such inner disturbance. Indulging yourself is just like a tiny hole in a dam. Once a hole has formed, the dam cannot hold; the water will inevitably destroy it. Indulgence does the same thing inside of us; everything will be dispersed, so it will be necessary to start all over again to restore ourselves. Fear this as your most evil enemy, although he speaks with the sweetest words.
Such are the souls of the saints: they love their enemies more than themselves, and in this age and in the age to come they put their neighbor first in all things, even though because of his ill-will he may be their enemy.
The kingdom of God is within us when God reigns in us, when the soul in its depths confesses God as its master, and is obedient to Him in all its powers. Then God acts within it as master ‘both to will and to do of his good pleasure’ (Phil. ii. 13). This reign begins as soon as we resolve to serve God in our Lord Jesus Christ, by the grace of the Holy Spirit. Then the Christian hands over to God his consciousness and freedom, which comprises the essential substance of our human life, and God accepts the sacrifice; and in this way the alliance of man with God and God with man is achieved, and the covenant with God, which was severed by the fall and continues to be severed by our willful sins, is re-established. This inner alliance is sealed, confirmed, and given the strength to maintain itself by the power of grace in the divine sacrament of baptism, and for those who have fallen after baptism, in the sacrament of repentance: and afterwards it is constantly strengthened by holy communion. All Christians live thus; and consequently they all bear the kingdom of God within themselves, that is to say they obey God as King and are ruled by God as King.
We ought all of us always to give thanks to God for both the universal and the particular gifts of soul and body that He bestows on us. The universal gifts consist of the four elements and all that comes into being through them, as well as all the marvelous works of God mentioned in the divine Scriptures. The particular gifts consist of all that God has given to each individual. These include wealth, so that one can perform acts of charity; poverty, so that one can endure it with patience and gratitude; authority, so that one can exercise right judgment and establish virtue; obedience and service, so that one can more readily attain salvation of soul; health, so that one can assist those in need and undertake work worthy of God; sickness, so that one may earn the crown of patience; spiritual knowledge and strength, so that one may acquire virtue; weakness and ignorance, so that, turning one's back on worldly things, one may be under obedience in stillness and humility; unsought loss of goods and possessions, so that one may deliberately seek to be saved and may be helped when incapable of shedding all one's possessions or even of giving alms; ease and prosperity, so that one may voluntarily struggle and suffer to attain the virtues and thus become dispassionate and fit to save other souls; trials and hardship so that those who cannot eradicate their own will may be saved in spite of themselves, and those capable of joyful endurance may attain perfection.
Not every man can be trusted when giving advice to those who seek it. We can trust only him who has received from God the grace of discrimination and who ... has acquired through great humility and long practice of the virtues an intellect blessed with spiritual insight. Such a man is in a position to advise, not everyone, but at least those who seek him out voluntarily and who question him by their own choice; for he has learned things in their true order.
Monasticism itself is a perpetual labor of conquering passions and uprooting them in order that, being in a pure and immaculate state, one may preserve oneself before the face of God. This, then, is your task! Give your attention to it, and direct all your powers towards it.
At this point the zealous man looks inward, and what do you think he finds there? Ceaseless wandering of thoughts, constant onslaughts from the passions, hardness and coldness of heart, obstinacy and disobedience, desire to do everything according to his own will. In a word, he finds everything within himself in a very bad state. And seeing this, his zeal is inflamed, and he now directs strenuous efforts to the development of his inner life, to controlling his thoughts and the dispositions of his heart. From directions on inner spiritual life he discovers the necessity of paying attention to oneself, of watching over the movements of the heart. In order not to admit to anything bad, it is necessary to preserve the remembrance of God. And so he sets to work to achieve this remembrance. But his thoughts can no more be arrested than the wind; his bad feelings and worthless impulses can no more be evaded than the stench of a corpse; his mind, like a wet and frozen bird, cannot rise to the remembrance of God. What is to be done? Be patient, they say, and go on working. Patience and labor are exercised, but all within remains the same. At last someone of experience is found who explains that all is inwardly in disorder because the forces within are divided: mind and heart each go their own way. Mind and heart must be united; then wandering of thoughts will cease, and you will gain a rudder to steer the ship of your soul, a lever by which to set in movement all your inner world. But how can one unite mind and heart? Acquire the habit of praying these words with the mind in the heart, 'Lord Jesus Christ, Son of God, have mercy upon me'. And this prayer, when you learn to perform it properly, or rather when it becomes grafted to the heart, will lead you to the end which you desire. It will unite your mind with your heart, it will cut off your wandering thoughts, and give you the power to govern the movements of your soul.
The zealous are eager for ascetical struggles of self-forcing and self-opposition with the aim of self-correction, or of raising themselves to primordial purity, so that they might all the more speedily become worthy of communion with God. Obviously the more eager one is, the more diligently and longingly he does this, the sooner he achieves his goal.
What do we do when attacked by some criminal? We strike out at him and shout for help. Our cries are answered by the police, who then rescue us from danger. We must do the same in inner warfare with the passions. Filled with anger against them, call for assistance: Help me, O Lord! Jesus Christ, Son of God, save me! O God, make speed to save me! O Lord make haste to help me! Having thus called on the Lord, do not allow your attention to wander from Him, do not let it turn to what is happening within you, but go on standing before the Lord and imploring His help. This will make the enemy run away as though pursued by flames.
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.
Even if a person’s sin is not only obvious, but very grievous and comes from a hardened and unrepentant heart, do not condemn him, but raise your eyes to the wondrous and incomprehensible judgments of God; then you will see that many people, formerly full of iniquity, later repented and reached a high degree of sanctity, and that, on the other hand, others, who were on a high level of perfection, fell into a deep abyss. Take care, lest you also suffer this calamity through judging others.
Set as a goal the kindling of the fire of the spirit, so that the spiritual fire will burn in your heart and, gathering up all your strength into one, will begin to build your inner man and finally burn up the tares of your sins and passions.
You ask, 'Must one do something?' Of course one must! And do whatever comes along-in your circle of friends and in your surroundings-and believe that this is and will be your real work. More will not be demanded of you. It is a great misconception to think, whether for the sake of heaven or, as the modernists put it, to 'make one's mark on humanity,' that one must undertake great, reverberating tasks. Not at all. It is necessary only to do everything according to the commandments of God. Just what exactly? Nothing in particular - only those things which present themselves to everyone in the circumstances of life, those things which are required by the everyday happenings we all encounter. Let's take an example: a beggar comes up to you; it is God Who has brought him. God has brought you the beggar, of course, desiring you to act toward this beggar in a manner pleasing to Him, and He watches to see what you will actually do. It will please Him if you help. Will you? If you do what is pleasing to God, you will be taking a step toward the ultimate goal, the inheritance of heaven. Generalize this occurrence, and you will find that in every situation and at every encounter one must do what God wants him to do. And we know truly what He wants from the commandments He has given us. If someone seeks help, then help him. If someone has offended you, forgive him. If you yourself have offended someone, then hasten to ask forgiveness and to make peace. If someone has praised you, do not be proud. If someone has scolded you, do not get angry. If the time has come to pray, then pray. To work, then work, - etc. etc.
