How do we know that Jesus is our High Priest forever?

The New Testament teaches that Jesus is our eternal High Priest, as emphasized in Hebrews 7:17. This passage declares that Christ is appointed High Priest after the order of Melchizedek, which signifies a priesthood that is not based on lineage or the law, but on His eternal life. Unlike the Levitical priests, who were subject to death and could not offer permanent solutions for sin, Christ's priesthood is established through an everlasting oath from God. This eternal priesthood ensures that He can intercede for His people continually, saving them to the uttermost.
