On Mortification of the Passions, by St. John of Damascus

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.

In this way he emulates the psalmist, who wrote: 'Lord, my heart is not haughty, nor are my eyes presumptuous' (Ps. 131:1). But after having reached such heights he must be careful lest through negligence or self -inflation he suffers what David suffered, without perhaps being able to repent as David did. For to sin, even in the case of those who are most righteous, is easy, while repentance is not easy for everyone because death is near; and even before death comes there is despair. It is good, then, not to fall; or, if we fall, to rise again. And should we fall, we should not despair and so estrange ourselves from the Lord's love. For if He so chooses. He can deal mercifully with our weakness. Only we should not cut ourselves off from Him or feel oppressed when constrained by His commandments, nor should we lose heart when we fall short of our goal. Rather, let us learn that a thousand years in the sight of the Lord are but a single day, and a single day is as a thousand years (cf. Ps. 90:4). Let us be neither hasty nor tardy, and let us be always ready to make a new start. If you fall, rise up. If you fall again, rise up again. Only do not abandon your Physician, lest you be condemned as worse than a suicide because of your despair. Wait on Him, and He will be merciful, either reforming you, or sending you trials, or through some other provision of which you are ignorant. “These eight passions should be destroyed as follows: gluttony by self-control; unchastity by desire for God and longing for the blessings held in store; avarice by compassion for the poor; anger by goodwill and love for all men; worldly dejection by spiritual joy; listlessness by patience, perseverance and offering thanks to God; self-esteem by doing good in secret and by praying constantly with a contrite heart; and pride by not judging or despising anyone in the manner of the boastful Pharisee (cf. Luke 18 : 11–12), and by considering oneself the least of all men. (V3 232-233)

…

From inward grief, then, and patient endurance come hope and detachment; and through hope and detachment we die to the world. We may also die to the world by enduring patiently and by not despairing when we see everywhere dismay and death, knowing that this is both a trial and an illumination; or by not being over-confident about having reached our goal. Shedding many tears of distress, we begin to see clearly before us the holy sufferings of the Lord, and we are greatly solaced by them. And we truly regard ourselves as inferior to all other men, perceiving how many blessings are bestowed on us through the grace of God, to whom be glory and dominion through all the ages. Amen. (V3 234)
