The Levitical priesthood, instituted under the Mosaic Law, could not bring perfection or complete access to God. It was always meant to be temporary and preparatory. Jesus is a priest in the order of Melchizedek, not Aaron. Melchizedek's priesthood is eternal and not based on ancestry. Jesus, like Melchizedek, holds His priesthood permanently because He lives forever. This eternal priesthood brings a better hope, allowing us to draw near to God because his sacrifice is permanent. His resurrection and ascension places Christ in a superior place than the OT temple. We might be tempted to think that our representation is inferior to the priests of old, but Hebrews teaches that it is superior because the promise is confirmed.
