You describe how bitterly you regret the inefficacy of your prayers. Beware: to wish for consolation or revelation in prayer is a sure sign of pride. Pray humbly, in perfect simplicity, seeking salvation only through forgiveness, & having faith that God will extend to you His mercy - as He did to the publican.
Those who attend the divine service of the Orthodox Church must bear in mind that its purpose is to prepare us for the joyful service of God in heaven; that in serving God with the body, it is still more necessary to serve God with the soul and a pure heart; that in hearing divine service they must learn to serve God as those saints served him, whose lives, and works of faith, hope and love, we hear of during the service; that God should, above all, be served in deed and truth, and not only by words and the tongue.
Sometimes we do not see any outlet, any escape from our sins, and they torment us: on account of them, the heart is oppressed with sorrow and weary. But Jesus looks upon us, and streams of tears flow from our eyes, and with the tears all the tissue of evil in our soul vanishes. We weep with joy that such mercy has suddenly and unexpectedly been sent to us.
When the flesh flourishes, the soul fades; when the flesh has full liberty, the soul is straitened; when the flesh is satiated, the soul hungers; when the flesh is adorned, the soul is deformed; when the flesh overflows with laughter, the soul is surrounded by misfortune; when the flesh is in the light, the soul is in darkness...
Men who are leading a spiritual life see by the eyes of their heart how the devil lays his snares, how the angels guide us, and how the Lord, in His Sovereign power, allows the temptations, and how he comforts.
Remember always that, once we have decided consciously to strive after righteousness, we cannot escape catastrophes and sorrows, no matter where we are.
Faith is truly a gift, gained for us through Christ's advent. But this does not abolish our freedom or responsibility. God desires of us not only faith but action too.
Keep a strict watch against any appearance of pride: it appears imperceptibly, particularly in time of vexation and irritability against others for quite unimportant causes.
What does the daily invocation of the saints signify - of different ones each day, during the whole year, and during our whole life? It signifies that God's saints, as our brethren - but perfect - live, and are near us, ever ready to help us, by the grace of God. We live together with them in the house of our Heavenly Father, only in different parts of it. We live in the earthly, they in the heavenly half, but we can converse with them, and they with us. God's saints are near to the believing heart, and are ready in a moment to help those who call upon them with faith and love.
You are, I am sure, aware that for you penitence is now no longer limited to disclosing your sins to your confessor, but that you must now bear your sins in mind always, until your heart nearly breaks with their ugly load; and would break, were it not for your firm faith in the mercy of our Lord.
Do not think that even here any one of us constantly enjoys consolation. No: here, as everywhere, flesh and mind are at war; here as everywhere, there is falling into pride and purification through humbling: here, as everywhere, we long for consolations but must learn to carry a weighty cross. This cross tests our love. Can we, do we love God even under the weight of the most bitter adversities?
Oh, what great happiness and bliss, what exaltation it is to address oneself to the Eternal Father. Always, without fail, value this joy which has been accorded to you by God's infinite grace and do not forget it during your prayers; God, the angels and God's holy men listen to you.
If you wish to correct any one from his faults, do not think of correcting him solely by your own means: you would only do harm by your passions, for instance, by pride and by the irritability arising from it; 'but cast thy burden upon the Lord,' and pray to God, Who 'searcheth the hearts and reins,' with all your heart, that He Himself may enlighten the mind and heart of that man. If He sees that your prayer breathes love, and that it really comes from the depth of your heart, He will infallibly fulfill the desire of your heart, and you yourself will soon tell, seeing the change that has taken place in him for whom you have prayed, that it is the work of the right hand of God, the most High.
