What does Hebrews teach about the nature of Christ's priesthood?

The nature of Christ's priesthood, as outlined in the book of Hebrews, emphasizes His eternal and unchangeable status as our high priest. Unlike the Levitical priests, who were mortal and had to continually offer sacrifices, Christ offered Himself once for all, making Him a permanent priest who has the authority to intercede for His people. Hebrews 7:24-25 emphasizes that Christ holds His priesthood permanently because He continues forever, enabling Him to save to the uttermost those who draw near to God through Him. This assurance allows believers to have boldness in approaching God, knowing that their high priest is continually advocating on their behalf.
