14 how much more will the blood of Christ, who through the eternal Spirit offered himself without blemish to God, purify our[1] conscience from dead works to serve the living God.
15 Therefore he is the mediator of a new covenant, so that those who are called may receive the promised eternal inheritance, since a death has occurred that redeems them from the transgressions committed under the first covenant.[2] 16 For where a will is involved, the death of the one who made it must be established. 17 For a will takes effect only at death, since it is not in force as long as the one who made it is alive.
Matthew Henry's Commentary on Hebrews 9:14-17
Commentary on Hebrews 9:11-14
(Read Hebrews 9:11-14)
All good things past, present, and to come, were and are founded upon the priestly office of Christ, and come to us from thence. Our High Priest entered into heaven once for all, and has obtained eternal redemption. The Holy Ghost further signified and showed that the Old Testament sacrifices only freed the outward man from ceremonial uncleanness, and fitted him for some outward privileges. What gave such power to the blood of Christ? It was Christ's offering himself without any sinful stain in his nature or life. This cleanses the most guilty conscience from dead, or deadly, works to serve the living God; from sinful works, such as pollute the soul, as dead bodies did the persons of the Jews who touched them; while the grace that seals pardon, new-creates the polluted soul. Nothing more destroys the faith of the gospel, than by any means to weaken the direct power of the blood of Christ. The depth of the mystery of the sacrifice of Christ, we cannot dive into, the height we cannot comprehend. We cannot search out the greatness of it, or the wisdom, the love, the grace that is in it. But in considering the sacrifice of Christ, faith finds life, food, and refreshment.
Commentary on Hebrews 9:15-22
(Read Hebrews 9:15-22)
The solemn transactions between God and man, are sometimes called a covenant, here a testament, which is a willing deed of a person, bestowing legacies on such persons as are described, and it only takes effect upon his death. Thus Christ died, not only to obtain the blessings of salvation for us, but to give power to the disposal of them. All, by sin, were become guilty before God, had forfeited every thing that is good; but God, willing to show the greatness of his mercy, proclaimed a covenant of grace. Nothing could be clean to a sinner, not even his religious duties; except as his guilt was done away by the death of a sacrifice, of value sufficient for that end, and unless he continually depended upon it. May we ascribe all real good works to the same all-procuring cause, and offer our spiritual sacrifices as sprinkled with Christ's blood, and so purified from their defilement.
