2 Corinthians 2:11
7 Humble then your heart, thou too, that you may draw God unto you. “For the Lord is near unto them that are of a contrite heart.” Do you see not in the gorgeous houses those who are in disgrace; how they answer not again when even the lower servants insult them, but put up with it because of the disgrace with which their fault has surrounded them? So do thou too: and if any one revile you, wax not fierce, but groan, not for the insult, but for that sin which cast you into disgrace. Groan when you have sinned, not because you are to be punished, (for this is nothing,) but because you have offended your Master, one so gentle, one so kind, one that so loves you and longs for your salvation as to have given even His Son for you. For this groan, and do this continually: for this is confession. Be not today cheerful, tomorrow of a sad countenance, then again cheerful; but continue ever in mourning and self contrition. For, “Blessed,” says he, “are they that mourn,” that is, that do this perpetually. Continue then to do this perpetually, and to take heed to yourself, and to afflict your heart; as one who had lost a beloved son might mourn. “Rend,” says he, “your hearts, and not your garments.” That which is rent will not lift itself on high; that which has been broken cannot rise up again. Hence one says, “Rend,” and another, “a broken and a contrite heart God will not despise.” Yea, though thou be wise, or wealthy, or a ruler, rend your heart. Suffer it not to have high thoughts nor to be inflated. For that which is rent is not inflated, and even if there be something to make it rise, from being rent it cannot retain the inflation. So also do thou be humble-minded. Consider that the publican was justified by one word, although that was not humiliation, but a true confession. Now if this has power so great, how much more humiliation. Remit offenses to those who have transgressed against you, for this too remits sins. And concerning the former He says, “I saw that he went sorrowful, and I healed his ways;” and in Ahab's case, this appeased the wrath of God: concerning the latter, “Remit, and it shall be remitted unto you.” There is also again another way which brings us this medicine; condemning what we have done amiss; for, “Declare first your transgressions, that you may be justified.” And for one in afflictions to give thanks looses his sins; and almsgiving, which is greater than all.
Reckon up therefore the medicines which heal your wounds, and apply all unremittingly, humbleness, confession, forgetting wrongs, giving thanks in afflictions, showing mercy both in alms and actions, persevering in prayer. So did the widow propitiate the cruel and unyielding judge. And if she the unjust, much more thou the gentle. There is yet another way along with these, defending the oppressed; “for,” He says, “judge the fatherless, and plead for the widow; and come, and let us reason together, and though your sins be as scarlet, I will make them white as snow.” What excuse then can we deserve if with so many ways leading us up to heaven, and so many medicines to heal our wounds, even after the Laver we continue where we were. Let us then not only continue so, but let those indeed who have never yet fallen abide in their proper loveliness; yea, rather let them cultivate it more and more, (for these good works, where they find not sins, make the beauty greater:) and let us who in many things have done amiss, in order to the correction of our sins use the means mentioned: that we may stand at the tribunal of Christ with much boldness, whereunto may all we attain through the grace and love towards men of our Lord Jesus Christ, with Whom to the Father, together with the Holy Spirit, be glory, and power, and honor, now and ever, world without end. Amen.
