In the grim struggle with the invisible enemies of our salvation, the supreme weapon is the prayer of Jesus. `All the nations' - the vociferous and wily demons are called nations - `surround me,' says David, `and in the name of the Lord I repulsed them. They encircled and surrounded me like bees, and they burnt like fire among thorns; and in the name of the Lord I repulsed them' (Ps. 117:10-12). With the name of Jesus flog the foes, because there is no stronger weapon in heaven or earth.
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...
In words of boastfulness and self-justification there always lie concealed contrariness and pride, from which God turns away. After sinning one ought immediately to 'flee.' But you say, where? To the calm haven of heartfelt repentance.
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 your work, flee conversation; only measured words in case of need. The hands should work for the needs of the body, and the mind should say the sweetest name of Christ, so that the need of the soul, which we must not forget even for moment, also will be provided for.
All Christians, clergy, laity and monks, when rising from sleep must first think of and remember Christ. They must offer this remembrance to Christ as a sacrifice and first-fruits of every thought (Hebrews 13:15). For we must remember, before every thought, Christ Who saved us and has loved us so greatly, for we are, and are called, 'Christians'. We put him on by divine Baptism (Gal. 3:27), and we were sealed with His Chrism. We have partaken, and do partake, of His holy Body and Blood. We are His members (I Cor. 12:27) and His temple (II Cor. 6:16). Him do we put on, and He dwells in us. For this reason we are obliged to love Him and remember Him always. Wherefore, let everyone devote time, according to his ability, and have a certain amount of this prayer as an obligation. And this suffices concerning this matter, for this is a sufficient amount of instruction for those who seek concerning it.
Let us work with the body and pray with the soul. Let our outer man perform his bodily tasks, and let the inner man be entirely dedicated to the service of God, never abandoning this spiritual practice of mental prayer, as Jesus, God and Man, commanded us, saying: 'But thou, when thou prayest, enter into thy closet, and when thou hast shut thy door, pray to thy Father which is in secret' (Matthew 6:6).The closet of the soul is the body; our doors are the five bodily senses. The soul enters its closet when the mind does not wander hither and thither, roaming among things and affairs of the world, but stays within, in our heart. Our senses become closed and remain closed when we do not let them be attached to external sensory things, and in this way our mind remains free from every worldly attachment, and by secret mental prayer unites with God its Father. 'And thy Father which seeth in secret shall reward thee openly,' adds the Lord. God who knows all secret things sees mental prayer and rewards it openly with great gifts. For that prayer is true and perfect which fills the soul with Divine grace and spiritual gifts. As chrism perfumes the jar the more strongly the tighter it is closed, so prayer, the more fast it is imprisoned in the heart, abounds the more in Divine grace.
Do not hesitate to go late at night to those places where you usually feel afraid. But if you yield only a little to such weakness, then this childish and ridiculous infirmity will grow old with you. As you go on your way, arm yourself with prayer. When you reach the place, stretch out your hands. Flog your enemies with the name of Jesus, for there is no stronger weapon in heaven or earth. When you get rid of the disease of fear, praise Him who has delivered you. If you continue to be thankful, He will protect you for ever.
Join to every breath a sober invocation of the name of Jesus and the thought of death with humility. Both these practices bring great profit to the soul.
Watchfulness and the Jesus Prayer, as I have said, mutually reinforce each other, for close attentiveness goes with constant prayer, while prayer goes with close watchfulness and attentiveness of intellect.
Cultivate the Jesus Prayer and a time will come when your heart will leap with joy, just as it does when you are about to see a person who you love very much.
Man's chief aim should be to find God. In finding God, he finds true happiness. The interior prayer we have been discussing [the Prayer of Jesus] leads man to Him. We can never thank God sufficiently for revealing Himself to us. We can never even thank Him enough for the other goods He bestows upon us. God need not have created man: He had hosts of angels. Yet He created man and countless marvelous things for him.
It is no small struggle to be freed from self-esteem. Such freedom is to be attained by the inner practice of the virtues and by more frequent prayer; and the sign that you have attained it is that you no longer harbor rancor against anybody who abuses or has abused you.
This mental prayer is the light which illumines man’s soul and inflames his heart with the fire of love of God. It is the chain linking God with man and man with God. Oh the incomparable blessing of mental prayer! It allows a man constantly to converse with God. Oh truly wonderful and more than wonderful – to be with one’s body among men while in one’s mind conversing with God. Angels have no physical voice, but mentally never cease to sing glory to God. This is their sole occupation and all their life is dedicated to this.
