How do we know the priesthood of Jesus is superior?

The superiority of Jesus' priesthood is articulated in Hebrews 7, where the author draws parallels between Melchizedek and Christ. Unlike the Levitical priests who were required to offer sacrifices for their own sins, Jesus, being sinless, does not face such a requirement. His order of priesthood is after Melchizedek, which emphasizes His eternal nature, affirming that His priesthood is based on the power of an indestructible life. This suggests that Jesus, as the High Priest, effectively mediates for us without the limitations faced by earlier priests, making His intercession perfect and complete.
