Melchizedek was king of Salem (Jerusalem) and priest of the God Most High. He met and blessed Abraham and Abraham gave him a tenth of everything (Genesis 14:18-20). His name means “king of righteousness” and king of Salem means “king of peace”. He remains a priest forever without the proper lineage.
Just think how great he must have been for Abraham to give him a tenth of the plunder! The law requires the descendants of Levi to collect a tenth from the people. Melchizedek was not a Levite. One could deduce that Levi collects the tenth through Abraham because Levi (who is Abraham’s descendant) hadn’t been born yet when Melchizedek collected. Hence we have Levites paying tithes to Melchizedek, making Melchizedek greater than the Levites (or Abraham in this instance since the Levites are through Abraham). Since the lesser is blessed by the greater, Melchizedek is greater than Abraham.
Perfection could not be attained through the Levites so there was need for a priest in the order of Melchizedek (the mere fact that a priest in the order of Melchizedek shows up should be a clue that there is a need for something better than the Levites). If the priests change, then so must the law. The old law was weak and useless for it made nothing perfect and a better hope was introduced by God (Jesus!).
Through an oath Jesus became a priest and the author of a better covenant. Jesus lives forever so his priesthood is forever; therefore, he is able to save completely those who come to God through him.
Jesus meets our needs as holy, blameless, pure, set apart from sinners, exalted above the heavens with one sacrifice of himself who has been made perfect forever.
Melchizedek comes and vanishes as quickly. Yet, he leaves an impression that can make all the difference. What impression do you leave with others?
