What does Hebrews 7:28 mean?
This verse summarizes the conclusion of the author's argument: high priests of the Old Testament were flawed, but appointed by the God-given Law to serve their purpose (Galatians 3:19—4:6). Jesus, on the other hand, is perfect. In the book of Hebrews, the word perfect is most often a reference to something being completed (Hebrews 5:9). Here, however, the context includes the idea of Christ's sinlessness and moral perfection (Hebrews 4:15). Jesus has been appointed to His position directly by God (Hebrews 7:17, 21), unlike Levitical priests who inherit their titles (Hebrews 7:20). Jesus lives forever (Hebrews 7:16), and does not lose His priesthood to death as mortal priests will (Hebrews 7:23). Human efforts will be incomplete (Hebrews 7:18–19), but Jesus' efforts remove our sin completely (Hebrews 7:25).In the next chapter, the author will build from his last two ideas. These were the idea of Melchizedek being greater than Abraham, and the priesthood of Jesus—on the order of Melchizedek—being greater than that of the Levitical priests. These will be the springboard to a deeper discussion of how, and why, Jesus' role in our salvation is exactly what God has always been promising us. The Old Covenant, while flawed, is not a mistake or a failure by God. It is simply part—and only part—of His overall plan.
