How does the priesthood of Christ differ from the Levitical priests?

Hebrews highlights that Christ is a priest forever after the order of Melchizedek, which distinguishes Him from the Levitical priests who served temporarily and needed to offer sacrifices repeatedly. In Hebrews 7:23-24, it is emphasized that while many became priests because they were prevented by death from continuing, Christ holds His priesthood permanently because He continues forever. This eternal aspect of His priesthood ensures continual intercession for believers and the certainty of eternal salvation as opposed to the ineffective sacrifices of the Levitical priests.
