St. John of Kronstadt, On Prayer

When you see faults and passions in your neighbor, pray for him; pray for everybody, even for your enemy. If you see that your brother is proud and stubborn, and behaves proudly either to you or others, pray for him, that God may enlighten his mind and warm his heart with the fire of His grace, and say:

"Lord, teach meekness and humility to Thy servant, who has fallen into Satan's pride, and drive from his heart the darkness and burden of the evil one's pride."

If you see a wrathful brother, pray thus: "Lord, make this servant of Thine good through Thy grace."

If you see a mercenary and greedy one, pray thus: "Lord, Thou Who art our incorruptible Treasury and inexhaustible Riches, grant that this servant of Thine, created according to Thy image, may recognize the deceitfulness of riches, and that, like all earthly things, they are vain, fleeting, delusive. For the days of men are like grass, or like the spider's web, and Thou alone art our riches, peace, and joy."

If you see an envious man, pray thus: "Lord, enlighten the mind and the heart of this Thy servant, that he may recognize the great innumerable, and unsearchable gifts which he has through Thy boundless generosity; for in the blindness of his passion he has forgotten Thee and Thy rich gifts, and although enriched with Thy benefits, yet he reckons himself poor, and looks enviously upon the blessings which Thou, O our unspeakable Benefactor, hast bestowed upon each one of Thy servants, even against their own will, but in accordance with Thy purpose. Take away, Most Gracious Master, the devil's veil from the eyes of the heart of Thy servant; grant him contrition of heart , tears of repentance and gratitude, so that the enemy who has ensnared him alive in his toils may not rejoice over him and may not wrest him from Thy hands."

If you see a drunken man, say in your heart: "Lord, look mercifully upon Thy servant, allured by the flattery of the belly and by carnal merriment, make him understand the sweetness of temperance and fasting, and of the fruit of the spirit arising therefrom."

When you see a man passionately fond of eating, and finding all his happiness in this, say: "Lord, Thou are our sweetest Food, that never perishes, but leads us unto life eternal! Purify Thy servant from the filthiness of gluttony, so carnal and so far from Thy Spirit, and grant that he may know the sweetness of Thy Life-giving, spiritual food, which is thy Flesh and Blood and Thy holy, living, and acting word."

In this or in similar manner pray for all who sin, and do not dare to despise anyone for his sin, nor be vindictive, as through this you would only aggravate the wounds of those who sin, but rather correct them by means of such advice, threats, and punishments as may tent to stop or restrain the evil within the limits of moderation.
