15 And for this reason He is the Mediator of the new covenant, by means of death, for the redemption of the transgressions under the first covenant, that those who are called may receive the promise of the eternal inheritance. 16 For where there is a testament, there must also of necessity be the death of the testator. 17 For a testament is in force after men are dead, since it has no power at all while the testator lives. 18 Therefore not even the first covenant was dedicated without blood. 19 For when Moses had spoken every precept to all the people according to the law, he took the blood of calves and goats, with water, scarlet wool, and hyssop, and sprinkled both the book itself and all the people, 20 saying, "This is the blood of the covenant which God has commanded you." 21 Then likewise he sprinkled with blood both the tabernacle and all the vessels of the ministry. 22 And according to the law almost all things are purified with blood, and without shedding of blood there is no remission.
23 Therefore it was necessary that the copies of the things in the heavens should be purified with these, but the heavenly things themselves with better sacrifices than these.
Matthew Henry's Commentary on Hebrews 9:15-23
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.
Commentary on Hebrews 9:23-28
(Read Hebrews 9:23-28)
It is evident that the sacrifices of Christ are infinitely better than those of the law, which could neither procure pardon for sin, nor impart power against it. Sin would still have been upon us, and have had dominion over us; but Jesus Christ, by one sacrifice, has destroyed the works of the devil, that believers may be made righteous, holy, and happy. As no wisdom, learning, virtue, wealth, or power, can keep one of the human race from death, so nothing can deliver a sinner from being condemned at the day of judgment, except the atoning sacrifice of Christ; nor will one be saved from eternal punishment who despises or neglects this great salvation. The believer knows that his Redeemer liveth, and that he shall see him. Here is the faith and patience of the church, of all sincere believers. Hence is their continual prayer as the fruit and expression of their faith, Even so come, Lord Jesus.
