Hebrews 7 asks a question that would have startled its first readers. If the priesthood God gave Israel through Aaron could have brought people to perfection, why would anyone need another priest? Yet God, speaking through David in Psalm 110, had already announced one: “You are a priest forever, in the order of Melchizedek.”
A system built on a priesthood
For centuries, Israel’s worship ran through the tribe of Levi. The law given to Moses appointed Aaron and his sons as priests, and those priests in turn served the law. They offered sacrifices, made atonement, and stood between a holy God and a sinful people.
But the author of Hebrews notices something deeper. The people received the law on the basis of that priesthood (7:11). The whole Sinai covenant depended on priests to make it work. Take away the foundation, and the building has to change: “For when the priesthood is changed, the law must be changed also” (7:12).
That is exactly what has happened. Jesus is now our high priest, yet he came from Judah, a tribe Moses never connected with the altar. His arrival means God is doing something new.
What “perfection” really means
When Hebrews speaks of perfection, it does not mean moral flawlessness. It means bringing worshippers all the way into God’s presence, with consciences truly cleansed (9:9; 10:14). The Levitical system, for all its beauty, could never do that. Its sacrifices were repeated year after year, a constant reminder that the way to God was not yet fully open.
A different kind of priest
Jesus belongs to the “order” of Melchizedek. That word does not describe a family line; it describes a kind of priesthood. Scripture records no genealogy for Melchizedek at all. To be a Levite was to be a priest by birth, because your ancestry assigned your role. Not so with Melchizedek, and not so with Christ.
Melchizedek was also both priest and king, and so is Jesus. He serves on our behalf, and he reigns over all.
Most importantly, Jesus became a priest “not on the basis of a regulation as to his ancestry but on the basis of the power of an indestructible life” (7:16). This is the resurrection. Every Levitical priest eventually died and had to be replaced. Jesus has passed through death and lives forever, which is why “he always lives to intercede” for those who come to God through him (7:25).
A law written on the heart
If the priesthood has changed, what is the new law? Hebrews answers by quoting Jeremiah’s promise of a new covenant: “I will put my laws in their minds and write them on their hearts” (8:10).
Here is the difference. Any law that imposes rules on people from the outside in, even the good and holy law of Moses, ends up exposing our trespasses. And trespass against God’s law brings a punishment we cannot bear. But our high priest serves a covenant that changes a person from the inside out, something no human law could ever accomplish.
And unlike the priests of old, he does not offer sacrifices over and over. He offered himself, once for all. He is both the priest and the sacrifice.
A priest and king who requires a response
A priest like this cannot be ignored. We must face him directly, grasp what it means that he offered himself for us, and respond. He is worth nothing less than the whole of our lives.
And as king, he deserves to be lifted up, made known, and glorified. This is the singular purpose of our lives: that the One for whom, through whom, and to whom are all things would be made famous.
Prayer
Lord, thank you for showing us through your word who you truly are. Thank you that you gave yourself so that we could once again be with you, and that you call us to live for you. May you be glorified through our lives. Amen.
