(4.) Having undertaken our debt, he underwent the penalty. Solomon says: He that is surety for a stranger shall smart for it. Christ, being surety for us, did smart for it. [1.] He bore our griefs and carried our sorrows, v. 4. He not only submitted to the common infirmities of human nature, and the common calamities of human life, which sin had introduced, but he underwent the extremities of grief, when he said, My soul is exceedingly sorrowful. He made the sorrows of this present time heavy to himself, that he might make them light and easy for us. Sin is the wormwood and the fall in the affliction and the misery. Christ bore our sins, and so bore our griefs, bore them off us, that we should never be pressed above measure. This is quoted (Matt. viii. 17) with application to the compassion Christ had for the sick that came to him to be cured and the power he put forth to cure them. [2.] He did this by suffering for our sins (v. 5): He was wounded for our transgressions, to make atonement for them and to purchase for us the pardon of them. Our sins were the thorns in his head, the nails in his hands and feet, the spear in his side. Wounds and bruises were the consequences of sin, what we deserved and what we had brought upon ourselves, ch. i. 6. That these wounds and bruises, though they are painful, may not be mortal, Christ was wounded for our transgressions, was tormented or pained (the word is used for the pains of a woman in travail) for our revolts and rebellions. He was bruised, or crushed, for our iniquities; they were the procuring cause of his death. To the same purport is v. 8, for the transgression of my people was he smitten, the stroke was upon him that should have been upon us; and so some read it, He was cut off for the iniquity of my people, unto whom the stroke belonged, or was due. He was delivered to death for our offences, Rom. iv. 25. Hence it is said to be according to the scriptures, according to this scripture, that Christ died for our sins, 1 Cor. xv. 3. Some read this, by the transgressions of my people; that is, by the wicked hands of the Jews, who were, in profession, God's people, he was stricken, was crucified and slain, Acts ii. 23. But, doubtless, we are to take it in the former sense, which is abundantly confirmed by the angel's prediction of the Messiah's undertaking, solemnly delivered to Daniel, that he shall finish transgression, make an end of sin, and make reconciliation for iniquity, Dan. ix. 24.
