[T]here was a silver lining around this cloud of priestly insufficiency. If God honored these inadequate things, it must mean that one day he would send a servant qualified to complete what these priests could not perform—to put away sin once for all.
That’s who Jesus Christ is. He became the final Priest and the final Sacrifice. Sinless, he did not offer sacrifices for himself. Immortal, he never has to be replaced. Human, he could bear human sins. Therefore he did not offer sacrifices for himself; he offered himself as the final sacrifice. There will never be the need for another. There is one mediator between us and God. One priest. We need no other. Oh, how happy are those who draw near to God through Christ alone.
