18 Even the first plan required a death to set it in motion. 19 After Moses had read out all the terms of the plan of the law - God's "will" - he took the blood of sacrificed animals and, in a solemn ritual, sprinkled the document and the people who were its beneficiaries. 20 And then he attested its validity with the words, "This is the blood of the covenant commanded by God." 21 He did the same thing with the place of worship and its furniture. 22 Moses said to the people, "This is the blood of the covenant God has established with you." Practically everything in a will hinges on a death. That's why blood, the evidence of death, is used so much in our tradition, especially regarding forgiveness of sins.
23 That accounts for the prominence of blood and death in all these secondary practices that point to the realities of heaven. It also accounts for why, when the real thing takes place, these animal sacrifices aren't needed anymore, having served their purpose. 24 For Christ didn't enter the earthly version of the Holy Place; he entered the Place Itself, and offered himself to God as the sacrifice for our sins.
Matthew Henry's Commentary on Hebrews 9:18-24
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.
