A man who falls into sin is different from the way he was created. He is different, because he changes by his own actions the way he was meant to be. Man renounces himself when he becomes a different person through repentance. He leaves a corrupted man, which he had become through sin, and becomes such as he once was created, through mercy.
The virtue opposed to pride is humility. But as far as pride is loathsome and abominable, so welcome and lovely is humility to God and men. God Who is great and exalted looks on nothing so lovely as on an humble and compunctionate heart. Whence even the Most Holy Theotokos says of herself, For He hath regarded the low estate of His handmaiden. (Luke 1:48).
Remember, O my soul, the terrible and frightful wonder: that your Creator for your sake became Man, and deigned to suffer for the sake of your salvation. His angels tremble, the Cherubim are terrified, the Seraphim are in fear, and all the heavenly powers ceaselessly give praise; and you, unfortunate soul, remain in laziness. At least from this time forth arise and do not put off, my beloved soul, holy repentence, contrition of heart and penance for your sins.
The full and complete definition of repentance is that we never again allow in ourselves the sins of which we repent, or whereby our conscience is stung. The mark of satisfaction and forgiveness is when we have driven out from our hearts all desire for them.
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).
When I wish to open my mouth and to speak on the exalted theme of humility, I am filled with dread, like someone who is aware that he is about to discourse with his own imperfect words concerning God.
Only to the humble does the Lord reveal Himself in the Holy Spirit, but if we do not humble ourselves we shall not see God. Humility is the light in which we may behold the Light which is God, as the Psalmist sang: 'In Thy light we shall see light.'
If we remember the thief who, for a single confession on the cross, was taken into Paradise, we shall realize that it was not for the merit of the life he lived that he obtained so great blessedness, but that it was his by the gift of God, Who had mercy on him. Or, let us think of David, the king, whose two grievous and awful crimes were wiped away by one word of penitence. Neither here do we see that the merit of what he did was equal to obtaining pardon for such great offense, but the grace of God did the more abound when on the occasion of true penitence He did away with all that weight of sin for one single word of genuine confession. Again, when we consider the beginnings of man's calling and salvation, which, as the Apostle tells us, is not of ourselves or of our words, but we are saved by the gift and grace of God, we shall be able clearly to perceive how the end of perfection is not 'of him that willeth, nor of him that runneth, but of God Who showeth mercy,' Who makes us victors over our vices, although we have no merit at all of life or labors to weigh against them, nor does the effort of our will avail for us to reach the steep summit of righteousness, or to subdue the flesh which we are bound to use... For the outcome of all good flows from His grace, Who hath bestowed so great an eternity of bliss and such immeasurable glory, with manifold generosity, upon the weak will and the short life-work of man.
Take remarks without grumbling: be thankful when you are scorned, disregarded, ignored. But do not create humbling situations; they are provided in the course of the day as richly as you need. We notice the person who is for ever bowing and fussily servile, and perhaps say, How humble he is! But the truly humble person escapes notice: the world does not know him (I John 3:I); for the world he is mostly a 'zero.'
The grace of repentance, which acts in those who struggle, is a patristic inheritance. It is a divine transaction and exchange in which we give dust and receive heaven. We exchange matter for the Spirit. Every drop of sweat, every pain, every ascesis for God is an exchange.
For everyone who prays to God, ‘Lord, give me humility’ ought to know what he is asking for, viz. that God send him someone to mistreat him. And when he is insulted by someone, he ought to disparage himself and despise his own opinion so that when the other man humiliates him outwardly, he too humiliates himself inwardly.
Repentance is real when afterwards you keep trying strenuously to live now as you ought; but without this it is not very effectual, if you repent just to say your sins & to keep on living as before.
