The most important thing in any good effort and the height of all activities is to persevere in prayer, by means of which we can always acquire through supplication the other virtues from God as well.
The head of every good striving and the pinnacle of all corrections is to persevere in prayer, by which we may ever obtain, through entreaty of God, all the other virtues as well. By prayer those who are worthy partake of the sanctity of God and spiritual activity and the union of the mind with the Lord in unutterable love. He who constantly forces himself to endure in prayer is roused by spiritual love to Divine fervor and flaming desire towards God, and he receives, according to his measure, the grace of spiritual, sanctifying perfection.
He who is afraid of God's punishment has a slave-like fear of God, and it is this that makes him refrain from evil: 'Out of fear of the Lord men shun evil' (Prov. 16:6. LXX)... through fear of what threatens us we sinners may be led to repent and may seek deliverance from our sins...The more a man struggles to do good, the more fear grows in him, until it shows him his slightest faults, those which he thought of as nothing while he was still in the darkness of ignorance. When fear in this way has become perfect, he himself becomes perfect through inward grief: he no longer desires to sin but, fearing the return of the passions, he remains in this pure fear invulnerable. As the psalm puts it, 'The fear of the Lord is pure, and endures for ever' (Ps. 19:9. LXX). The first kind of fear is not pure, for it arises in us because of our sins. But, independent of sin, the person who has been purified continues to feel fear, not because he sins, but because, being human, he is changeable and prone to evil. In his humility, the further he advances through the acquisition of the virtues, the more he fears. This is natural; for everyone who possesses wealth greatly fears loss, punishment, dishonor, and the consequent fall from his high estate...The sign of the first kind of fear is hatred of sin and anger towards it, like someone wounded by a wild beast. The sign of perfect fear is the love of virtue and the fear of relapsing, since no one is unalterable.
It is always possible to make a new start by means of repentance. 'You fell,' it is written, 'now arise'(cf. Prov. 24:16). And if you fall again, then rise again, without despairing at all of your salvation, no matter what happens. So long as you do not surrender yourself willingly to the enemy, your patient endurance, combined with self-reproach, will suffice for your salvation. 'For at one time we ourselves went astray in our folly and disobedience,' says St. Paul. '... Yet He saved us, not because of any good things we had done, but in His mercy' (Tit. 3:3,5).
The deeper the contrition, the better. But however deep the contrition, never admit a shadow of doubt about forgiveness. Forgiveness is already fully prepared and the record of all sins has been torn up on the Cross. Repentance and contrition alone are expected of every man, before he too can participate in the power of the redemption of the sins of the world through the Crucifixion.
Looking at yourself or at other people and thinking that you alone have been given high rank, that you alone of all living beings on earth have the gift of reason, and serve as the point of union and connection between material and immaterial creatures, rouse yourself to glorify and thank your God and Creator, and say: 'O eternal Trinity, Father, Son and Holy Spirit! Be Thou blessed forever! How greatly must I give Thee thanks at all times, not only because Thou hast created me out of earth and hast made me King over all earthly creatures, not only because Thou hast honored my nature with Thy likeness, with reason, speech and a living body, but above all because Thou hast given me the power, of my own free will, through virtues to resemble Thee, that thereby I may possess Thee in me and rejoice in Thee forever!
Patient endurance kills the despair that kills the soul; it teaches the soul to take comfort and not to grow listless in the face of its many battles and afflictions.
Self-esteem is so deeply rooted in us and so firmly enmeshed in us, making us think that we are something, and something not unimportant, that it always hides in our heart as a subtle and imperceptible movement, even when we are sure that we do not trust ourselves and are, on the contrary, filled with complete trust in God alone. In order to avoid this conceit of the heart and act without any self-reliance, led only by your trust in God, take care always to preserve an attitude in which the consciousness and feeling of your weakness always precede in you the contemplation of God's omnipotence, and let both alike precede your every action.
Pre-eminence belongs to the Jesus prayer because it unites the soul with our Lord Jesus, and the Lord Jesus is the only door to union with God, which is the aim of prayer.
Just as gold is found, washed out of a great amount of sand and it amounts to very small grains like millet, so also out of many human beings few will be approved. For those who seek the kingdom are clearly manifested, while those who merely wear its word as a beautiful ornament are the ones most conspicuous. For the same reason those are manifested who are seasoned with the heavenly salt and who speak out of the Spirit's treasures. The vessels appear in whom God is pleased and to whom He gives His grace. There are also others, who, with much patience, receive the sanctifying power in many different ways, as God wishes.
When a man has been sufficiently illumined, however, to perceive his own faults, he never ceases mourning for himself and for all men, seeing God’s great forbearance and what sins we in our wretchedness have committed and still persist in committing. As a result of this he becomes full of gratitude, not daring to condemn anyone, shamed by the profusion of God’s blessings and the multitude of our sins. Thereupon he joyfully renounces everything in his own will that is counter to God, and he watches over his own senses, so as to prevent them from doing anything beyond what is unavoidably needed.
Such are the souls of the saints: they love their enemies more than themselves, and in this age and in the age to come they put their neighbor first in all things, even though because of his ill-will he may be their enemy.
