Those who have truly decided to serve the Lord God must train themselves in the remembrance of God and in unceasing prayer to Jesus Christ, saying mentally: 'Lord Jesus Christ, Son of God, have mercy on me, a sinner.' Through such activity, and by guarding oneself from distraction, and with the preservation of peace in one's conscience, it is possible to draw near to God and to be united with Him. For, according to the words of St. Isaac the Syrian, 'Except for unceasing prayer we cannot draw near to God.'
One must endeavor to read through the writings of the Fathers, and strive as much as possible, according to one’s strength, to fulfill what they teach, and in this fashion, little by little ascend from the ascetic life to the perfection of the contemplative.
Favors are given in exchange of faith. Grace is poured out, which faith receives. And as from a fountain some draw a little water in little vessels, and others draw more in bigger vessels, the fountain not distinguishing between the one vessel and the other, since it is the vessels, not the fountain, that measures the water, and each draws according to his measure; and as the splendor of light enters to a greater or less degree according to the dimensions of the window, so is grace received according to the measure of our desire.
Brethren, let us also occupy yourselves with noetic prayer… and seeking God’s mercy, cry out with a humble heart from morning till night and if possible all night long, saying constantly: 'Lord Jesus Christ, Son of God, have mercy on us.'
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.
Do not leave the Church, for there is nothing mightier than She; She will never grow old and will always bloom; thus the Scriptures, showing Her durability and stability, calls Her a mountain.
How many are there that say: how much I wish to see Christ's fair form, His figure, His clothes. His very shoes. Why, here you see Him: you touch Him; you consume Him: and while you are longing to see His clothes, He gives you Himself, not to look at only, but to touch and to eat and to receive within you .... For it was not enough for Him to become man. Nor yet to be buffeted and slain. He ever mingles Himself with us, and makes us His Body, not by faith alone, but in very truth and reality,...That which the Angels behold with trembling and dare not gaze on with fear because of the radiance that beams from Him, with that we are fed.
The soul that really loves God and Christ, though it may do ten thousand righteousnesses, esteems itself as having wrought nothing, by reason of its insatiable aspiration after God. Though it should exhaust the body with fastings, with watchings, its attitude towards the virtues is as if it had not even begun to labor for them.
God's all-saving will consists in doing good solely to acquire the Holy Spirit, as an eternal, inexhaustible treasure which cannot be rightly valued... This is the oil in the lamps of the wise virgins which could burn long and brightly, and these virgins with their burning lamps were able to meet the Bridegroom Who came at midnight, and could enter the bridechamber of joy with Him. But the foolish ones, though they went to market to buy some oil when they saw their lamps going out, were unable to return in time, for the door was already shut. The market is our life; the door of the bridechamber which was shut and which barred the way to the Bridegroom is human death; the wise and foolish virgins are Christian souls; the oil is not good deeds but the grace of the All-Holy Spirit of God which is obtained through them and which changes souls from one state to another - that is, from corruption to incorruption, from spiritual death to spiritual life, from darkness to light, from the stable of our being (where the passions are tied up like dumb animals and wild beasts) into a temple of the Divinity, into the shining bridechamber of eternal joy in Christ Jesus our Lord, the Creator and Redeemer and eternal Bridegroom of our souls.
'Lord Jesus Christ, Son of God, have mercy on me, a sinner.' Let your attention and instruction be centered on this. Walking, eating, standing in church before the beginning of the service, continue with the prayer; on entering and departing keep this prayer on your lips and within your heart. In such a manner, with the invocation of the Name of God you will find peace, you will attain to purity of spirit and body; and the Holy Spirit, the Origin of all good, will make for Himself a dwelling within you and will guide you in all piety and purity.
The night was not made to be spent entirely in sleep. Why did Jesus Christ pass so many nights amid the mountains, if not to instruct us by His example? It is during the night that all the plants respire, and it is then also that the soul of man is more penetrated with the dews falling from Heaven; and everything that has been scorched and burned during the day by the sun's fierce heat is refreshed and renewed during the night; and the tears we shed at night extinguish the fires of passion and quieten our guilty desires. Night heals the wounds of our soul and calms our griefs.
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...
'Grace always precedes temptations.' He knew that grace always precedes temptations as a forewarning preparation. As soon as you perceive grace, gird yourself and say: 'Here comes the call to battle! Beware, attend, O Clay, to where the wicked on will strike the battle. Many times it comes quickly, and many times after two or three days. In any event, it will come, and the earthworks must be firm. Confessions every evening, Obedience to the elder, humility and love towards all. By these means lighten the affliction.' Grace is divided into three stages: purifying, enlightening, and perfecting. So also are deeds: natural, supernatural, contranatural. According to these three stages on ascends and descends. The great gifts one receives are also three: contemplation, love, dispassion.'
And as with regard to raiment and gold, when we expose them in a market-place, we attract many ill-meaning persons; but if we put them by at home and hide them, we shall deposit them all in security: even so with respect to our good deeds; if we are continually keeping them in memory, we provoke the Lord, we arm the enemy, we invite him to steal them away; but if no one know of them, besides Him who alone ought to know, they will lie in safety. Be not therefore for ever parading them, lest some one should take them away. As was the case with the Pharisee, for bearing them about upon his lips; whence also the devil caught them away. And yet it was with thanksgiving he made mention of them, and referred the whole to God. But not even did this suffice Him. For it is not thanksgiving to revile others, to be vainglorious before many, to exalt one's self against them that have offended. Rather, if thou art giving thanks to God, be content with Him only, and publish it not unto men, neither condemn thy neighbor; for this is not thanksgiving.
