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.
Do not judge one another, for you transgress the evangelical law, and 'every transgression and disobedience received a just retribution' (Heb. 2:2). 'Who are you to pass judgment on the servant of another?' (Rom. 14:4). Do you not know that the one who passes judgment goes astray through pride, and that everyone who exalts himself will be humbled (Luke 14:11) by the Lord, when temptation seizes him?
Fasting is an exceptional virtue; it represses bodily impulses and gives strength to the soul to fight against the poisoning of the heart through the senses, and provides it with a remedy against any past poisoning. Fasting causes the mind to be cleansed constantly. It withers up every evil thought and brings healthy, godly thoughts -- -holy thoughts that enlighten the mind and kindle it with more zeal and spiritual fervor.
Continually say the Prayer [of Jesus] intensely, with zeal, with longing; only thus does one become strong in soul. Avoid idle words by means of all sacrifice, for they weaken the soul and it does not have the strength to struggle.
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 old man (Abba Moses) was asked, 'What is the good of the fasts and watchings which a man imposes on himself?' and he replied, 'They make the soul humble. For it is written, ‘Consider my affliction and my trouble, and forgive all my sins’ (Psalm 25:18). So if the soul gives itself all this hardship, God will have mercy on it.'
After a spiritual conversation with Brother A. concerning what is profitable for the soul, I afterwards realized the absolute necessity of remembering never to begin speaking to my brother concerning what is profitable for the soul or concerning correction, and also not to listen to another’s explanations without first mentally turning to the Lord and asking His enlightenment for me and for my brother, and then speaking with awareness of God’s presence. And after the conversation both people must again turn to Christ the Savior and pray for His aid in fulfilling the Gospel and His all-good will as we were able to discern it in our conversation together. Let not our consultation together be in idleness, but remembering the words of our Lord Jesus Christ, ‘If two of you shall agree as touching any thing and ask My Father in My Name, He shall give it to you’ (cf. Matthew 18:19), let us have undoubting hope for our correction in all things.
If you examine your life well, you will find many instances when God showed His unmistakable mercy to you. Trouble was brewing, but it passed you by for some reason. God delivered you. Acknowledge these and thank God, Who loves you.
Grace is the food and clothing of the saints. It wakens grief in a man's heart, making him dissatisfied and moving him to seek the reason of this dissatisfaction. Grace gives sorrow and grace comforts; showing us the poverty of all things, it engenders in us a repentant sorrow for having fallen short of the love of God... One who is possessed by such sorrow will always grieve, for he thinks of God's offended love and not of the fear of hell. It is a grief of love.
I am a Christian, you say, and content yourself with this. This is the first deceit - transferring to yourself the privileges and promise of Christianity, without any care to root true Christianity into yourself; or to ascribe to yourself that which can only be acquired by your strength and inner worthiness. Explain to yourself that it is illusory to hope in a name, that God can raise a son of Abraham from a stone and can take away your promise at any time if the conditions for participating in them are not soon fulfilled. Mainly, clarify to yourself what it means to be a Christian, unite yourself to this ideal, and you will see just how stable is this buttress to your blindness.
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.
Many teach their children about worldly politics, others teach them to speak foreign languages: French, German, Italian, and in this spend no trifling sums. Others endeavor to teach them commerce and other arts. But hardly anyone teaches them to live in a Christian manner. However, without this, all learning is nothing and all wisdom is madness. For what does it profit a Christian to speak Italian, French and German, if he lives in an ungodly manner? What use is it to be skilled in commerce and the arts if one lacks the fear of God? God will not ask you whether you taught your children French, German or Italian or the politics of social life--but you will not escape divine reprobation for not having instilled goodness into them. I speak plainly but I tell the truth: if your children are bad, your grandchildren will be worse, and the evil will thus increase...and the root of all this is our thoroughly bad education.
The virtue opposed to pride is humility. But as far as pride is loathsome and abominable, so welcome and lovely is humility to God and men. God Who is great and exalted looks on nothing so lovely as on an humble and compunctionate heart. Whence even the Most Holy Theotokos says of herself, For He hath regarded the low estate of His handmaiden. (Luke 1:48).
