Hebrews 7 clarifies the reference in 6:20 to Melchizedek. Paul gives us some explanation of the significance of Jesus being our high priest “in the order of Melchizedek”. Melchizedek was the King of Salem , which means “king of peace” and Melchizedek means “king of righteousness”. Paul says that Melchizedek had no father or mother, no genealogy, and without beginning of days or end of life, so he remains a priest forever, just like the Son of God. Next, Paul explains that Jesus’s priesthood is superior to the levitical priesthood. They were appointed priests based on their ancestry, whereas Jesus demonstrated an “indestructible life”. Verse 6:12 says that with a change in the priesthood, there must also be a change in the law (regulations), so the former regulation is set aside “because it was weak and useless—for the law made nothing perfect”. “A better hope “ has been introduced in Jesus, by which we draw near to God. Furthermore, Paul says that Jesus has become a guarantee of a better covenant . And, since Jesus’ priesthood is forever, he is able to save completely. Jesus is holy and pure, so he was able to sacrifice for our sins once for all time when He offered himself for us, unlike the other high priests who needed to offer sacrifices day after day.
