10:15 {5} [Whereof] the Holy Ghost also is a witness to us: for after that he had said before,
(5) Although there remains in us relics of sin, yet the work of our sanctification which is to be perfected, hangs on the same sacrifice which never shall be repeated: and that the apostle proves by referring again to the testimony of Jeremiah, thus: Sin is taken away by the new testament, seeing the Lord says that it shall come to pass, that according to the form of it, he will no more remember our sins: Therefore we need now no purging sacrifice to take away that which is already taken away, but we must rather take pains, that we may now through faith be partakers of that sacrifice.
10:15 [Whereof] the Holy Ghost is also a witness to us. He testifies that Christ perfects the sanctified.
He had said before. See, too, that the Holy Spirit bears witness in words. He spoke in Jeremiah the prophet (Jer 31:33,34).
10:15 In this and the three following verse s, the apostle winds up his argument concerning the excellency and perfection of the priesthood and sacrifice of Christ. He had proved this before by a quotation from Jeremiah; which he here repeats, describing the new covenant as now completely ratified, and all the blessings of it secured to us by the one offering of Christ, which renders all other expiatory sacrifices, and any repetition of his own, utterly needless.
10:11-18 Under the new covenant, or gospel dispensation, full and final pardon is to be had. This makes a vast difference between the new covenant and the old one. Under the old, sacrifices must be often repeated, and after all, only pardon as to this world was to be obtained by them. Under the new, one Sacrifice is enough to procure for all nations and ages, spiritual pardon, or being freed from punishment in the world to come. Well might this be called a new covenant. Let none suppose that human inventions can avail those who put them in the place of the sacrifice of the Son of God. What then remains, but that we seek an interest in this Sacrifice by faith; and the seal of it to our souls, by the sanctification of the Spirit unto obedience? So that by the law being written in our hearts, we may know that we are justified, and that God will no more remember our sins.
