If you refuse to accept suffering and dishonor, do not claim to be in a state of repentance because of your other virtues. For self-esteem and insensitivity can serve sin even under the cover of virtue.
A true Christian is made by faith and love toward Christ. Our sins do not in the least hinder our Christianity, according to the word of the Savior Himself. He deigned to say: not the righteous have I come to call, but sinners to salvation; there is more joy in heaven over one who repents then over ninety righteous ones. Likewise concerning the sinful woman who touched His feet, He deigned to say to the Pharisee Simon: to one who has love, a great debt is forgiven, but from one who has no love, even a small debt will be demanded. From these judgments a Christian should bring himself to hope and joy, and not in the least accept an inflicted despair. Here one needs the shield of faith.
The designation of a Christian consists in glorifying the Heavenly Father by one's life. Let your light so shine before men, that they may see your good works, and glorify your Father which is in heaven (Matt. 5:16). But true glorification of God is possible only if one rightly believes and expresses his right belief in words and deeds.
Try to know yourself, your own wickedness. Think on the greatness of God and your wretchedness. Meditate on the suffering of Christ, the magnitude of Whose love and suffering surpass our understanding. Ascribe the good that you do to God alone. Do not think about the sin of a brother but about what in him is better than in yourself.... Flee from glory, honors and praise, but if this is impossible, be sorry that such is your lot. Be benevolent to people of low origin. Be freely and willingly obedient not only to those above you but to those below .... The lowlier we are in spirit, the better we know ourselves, and without humility we cannot see God.
The Christian ought not to be of doubtful mind, nor by anything drawn away from the recollection of God and of His purposes and judgments. The Christian ought in all things to become superior to the righteousness existing under the law, and neither swear nor lie. The Christian ought to be patient, whatever he has to suffer, and to convict the wrong-doer in season, not with the desire of his own vindication, but of his brother's reformation, according to the commandment of the Lord.
The soul of all practices in the Lord is vigilance. Without vigilance, all these practices are fruitless. He who is desirous of saving himself must so establish himself that he might remain continuously vigilant toward himself, not only in solitude, but also under conditions of distraction, into which he is sometimes unwillingly drawn by circumstances.
Let us go forward with the heart completely attentive and the soul fully conscious. For if attentiveness and prayer are daily joined together, they become like Elias' fire-bearing chariot, raising us to heaven. What do I mean? A spiritual heaven, with sun, moon and stars, is formed in the blessed heart of one who has reach a state of watchfulness, or who strives to attain it.
Some people when praised for their virtue are delighted, and attribute this pleasurable feeling of self-esteem to grace. Others when reproved for their sins are pained, and they mistake this beneficial pain for the action of sin.
Watchfulness cleanses the conscience and makes it lucid. Thus cleansed, it immediately shines like a light that has been uncovered, banishing such darkness. Once this darkness has been banished through constant and genuine watchfulness, the conscience then reveals things hidden from us.
If some Christians cannot comprehend our Orthodox faith, its Sacraments, it proves that the minds and hearts of such persons are too impure and passionate to bear its purity and brightness, just as sick eyes cannot bear the light of the sun. This heavenly treasure can only be comprehended by the hearts of those who free their minds and feelings from worldly attachments.
We must vigilantly guard our heart from unfitting thoughts and impressions, according to the word of the writer of Proverbs: ‘Keep thine heart with the utmost care; for out of these are the issues of life,’ (Proverbs 4:23).
If the saints, who had attained passionlessless, had to be vigilant over themselves so as not to fall from their state of grace - then all the more is daily attentiveness and concern over our eternal salvation necessary for us sinners. The fact that we are still alive means that the Lord patiently endures our sins and awaits our amendment, and if someone lawfully labors for his salvation, the Lord takes him at a time when he becomes worthy of God’s mercy.
