2 Corinthians 5:21

I say nothing of what has gone before, that ye have outraged Him, Him that had done you no wrong, Him that had done you good, that He exacted not justice, that He is first to beseech, though first outraged; let none of these things be set down at present. Ought ye not in justice to be reconciled for this one thing only that He hath done to you now? And what hath He done? "Him that knew no sin He made to be sin, for you." For had He achieved nothing but done only this, think how great a thing it were to give His Son for those that had outraged Him. But now He hath both well achieved mighty things, and besides, hath suffered Him that did no wrong to be punished for those who had done wrong. But he did not say this: but mentioned that which is far greater than this. What then is this? "Him that knew no sin," he says, Him that was righteousness itself, "He made sin," that is suffered as a sinner to be condemned, as one cursed to die. "For cursed is he that hangeth on a tree." (Galatians chapter 3, verse 13) For to die thus was far greater than to die; and this he also elsewhere implying, saith, "Becoming obedient unto death, yea the death of the cross." (Philippians chapter 2, verse 8) For this thing carried with it not only punishment, but also disgrace. Reflect therefore how great things He bestowed on thee. For a great thing indeed it were for even a sinner to die for any one whatever; but when He who undergoes this both is righteous and dieth for sinners; and not dieth only, but even as one cursed; and not as cursed [dieth] only, but thereby freely bestoweth upon us those great goods which we never looked for; (for he says, that "we might become the righteousness of God in Him;") what words, what thought shall be adequate to realize these things? For the righteous, saith he, He made a sinner; that He might make the sinners righteous. Yea rather, he said not even so, but what was greater far; for the word he employed is not the habit, but the quality itself. For he said not "made" [Him] a sinner, but "sin;" not, 'Him that had not sinned' only, but "that had not even known sin; that we" also "might become," he did not say 'righteous,' but, "righteousness," and, "the righteousness of God." For this is [the righteousness] "of God" when we are justified not by works, (in which case it were necessary that not a spot even should be found,) but by grace, in which case all sin is done away. And this at the same time that it suffers us not to be lifted up, (seeing the whole is the free gift of God,) teaches us also the greatness of that which is given. For that which was before was a righteousness of the Law and of works, but this is "the righteousness of God."
