Never was sin seen to be more abominably sinful and full of provocation, than when the burden of it was upon the shoulders of the Son of God. God having made his Son, the Son of his love, his only begotten, full of grace and truth, sin for us, to manifest his indignation against it, and how utterly impossible it is that he should let the least sin go unpunished, he lays hand on him, and spares him not. If sin be imputed to the dear Son of his bosom, as upon his own voluntary assumption of it it was (for he said to his Father, “Lo, I come to do thy will,” and all our iniquities did meet on him), [and] he will not spare him any thing of the due desert of it; is it not most clear from hence, even from the blood of the cross of Christ, that such is the demerit of sin, that it is altogether impossible that God should pass by any, the least, unpunished? If he would have done it for any, he would have done it in reference to his only Son; but he spared him not.
