Those who have truly decided to serve the Lord God should practice the remembrance of God and uninterrupted prayer to Jesus Christ, mentally saying: Lord Jesus Christ, Son of God, have mercy on me, a sinner.
St. John Climacus was asked if there are reliable signs by which it's possible to know whether a soul is drawing near to God or moving away from Him. After all, regarding ordinary things there are clear signs as to whether they're good or not. When, for instance, cabbage, meat or fish begins to rot, it's easy to notice it, since the rotting object begins to give off a foul odor, the color and taste change, and its external appearance witnesses to its deterioration. Well, and what about the soul? After all, it's bodiless and can't give off a bad smell or change its appearance. To this question the Holy Father replies, 'A sure sign of the deadening of the soul is the avoidance of church services.'
He who has not received within himself the kingdom of God cannot recognize the Antichrist. He is absolutely sure to become in a way incomprehensible to himself his follower.
As the earth, long awaiting moistening and at last receiving it in abundance, suddenly is covered by tender and bright greenery, so also the heart, exhausted by dryness, and afterwards revived by tears, emits from itself a multitude of spiritual thoughts and feelings, adorned by the common flower of humility. The labor of weeping, being inseparable from the labor of prayer, requires the same conditions for success as prayer requires. Prayer needs patient, constant dwelling in itself; weeping requires the same. Prayer needs wearying of the body, and brings about exhaustion of the body; this exhaustion produces weeping, which must be born in the troubling and wearying of the body.
People, until they come to know something greater, are satisfied with the little that they have. Man is like a village rooster who lives in a small enclosure with few people and farm animals about, who knows his ten hens and is content with this life, because he knows no more. But an eagle, who circles high in the clouds, and sees great distances with his sharp eyes, who hears the sounds of the earth and revels in its beauty, who knows many lands, seas and rivers, and sees a multitude of
animals and birds, would not be content to live in a small enclosure with a rooster. It is the same in spiritual life. Whoever has not known the grace of the Holy Spirit is like the rooster who does not know the flight of the eagle; he cannot comprehend the sweetness of tender emotion and love of God. He knows God from nature and from Scripture, he is satisfied with the law and is content with his lot as is the rooster, and does not feel sorrow that he is not an eagle. But he who has experienced the Lord through the Holy Spirit, he prays day and night, because the grace of the Holy Spirit calls him to love the Lord, and the sweetness of the Lord's love gives him the ability to carry the burdens of the world with ease; his soul pines only for the Lord and searches constantly for the grace of the Holy Spirit.
The Lord does not reveal Himself to many because of their intellectual pride; yet they think that they have much knowledge. But what is their knowledge worth, if they know not the Lord, know not the grace of the Holy Spirit, know not how this grace comes and wherefore it is lost? But let us humble ourselves, brethren, and the Lord will show us all things, as a loving father shows all things to his children.
The practice of the prayer of Jesus holy David, or more accurately the Holy Spirit by the mouth of David, offers to all Christians without exception: 'The kings of the earth and all people, princes and all judges of the earth, young men and maidens - let elders with the young praise the name of the Lord, for His name alone is exalted (PS. 148:11-13).' A literal understanding of the states enumerated here would be perfectly permissible, but their essential meaning is spiritual.
The Saints were people just like ourselves. Many of them started with grievous sins but through repentance they attained the Kingdom of Heaven. And every one who comes to the Kingdom of Heaven does so through repentance which the Merciful Lord granted us by His sufferings. In the Kingdom of Heaven, the holy Saints look upon the glory of our Lord Jesus Christ; but through the Holy Spirit they see, too, the sufferings of men on earth. The Lord gave them such great grace that they embrace the whole world with their love. They see and know how we languish in affliction, how our hearts have withered within us, how despondency has fettered our souls, and they never cease to intercede for us to God.
Obedience is necessary not only for monks, but for all people. Even the Lord was obedient. Proud and self-assured do not let grace reside within them, and therefore they never have internal peace, whereas the soul of the obedient easily accepts the grace of the Holy Spirit, bringing with it joy and serenity.
A mind that dwells on everyday matters of life and vain things disperses the soul. One should turn inwardly, looking at the soul’s uncultivated vineyard, weeding it of all evil thorns and planting virtues there instead. But be wary, for this type of work is not easy at all. It requires perseverance and much patience. One will be confronted with a multitude of difficulties. Various writings of the Fathers are very helpful, and in our days are available by the dozens. In them one can find anything his heart desires, and anything it needs. The Fathers will lead you on the right spiritual path, if only you read them with humility and prayer.
Then we say: 'Forgive us our trespasses as we forgive those who trespass against us.' Brothers, praying thus, we should very much fear lest the Lord reply to these words of our prayer: 'The judgments you give are the judgments you will get, and the amount you measure out is the amount you will be given.' And you who ask this, see whether you did to no one what you did not want done to you. Therefore before we hear these words of the Lord, brethren, let us first examine our hearts as to whether we are with justice asking of the Lord what we have not denied to those asking us. We ask that our trespasses be forgiven us. God hears and He wants to forgive us, but only if we first pardon those who ask us to do likewise.
He who chooses maltreatment and dishonor for the sake of truth is walking on the apostolic path; he has taken up the cross and is bound in chains (cf. Mt 16:24). But when he tries to concentrate his attention on the heart without accepting these two, his intellect wanders from the path and he falls into the temptations and snares of the devil.
Whoever repents sincerely is prepared to withstand any sorrow: hunger and homelessness, cold and heat, illness and poverty, humiliation and banishment, lies and slander, for the soul seeks God and does not concern itself with anything worldly, but instead prays with a clear mind.
Any soul which has lost its peace must repent, and the Lord will forgive its sins, and then peace and joy will visit the soul. There need be no witnesses, for the Holy Spirit is the witness of the remission of sins. Here is a sign of forgiveness: if you have come to hate sin, then the Lord has forgiven your sin.
