15-19But the Melchizedek story provides a perfect analogy: Jesus, a priest like Melchizedek, not by genealogical descent but by the sheer force of resurrection life—he lives!—"priest forever in the royal order of Melchizedek." The former way of doing things, a system of commandments that never worked out the way it was supposed to, was set aside; the law brought nothing to maturity. Another way—Jesus!—a way that does work, that brings us right into the presence of God, is put in its place.
20-22The old priesthood of Aaron perpetuated itself automatically, father to son, without explicit confirmation by God. But then God intervened and called this new, permanent priesthood into being with an added promise:
God gave his word;
he won't take it back:
"You're the permanent priest."
This makes Jesus the guarantee of a far better way between us and God—one that really works! A new covenant.
