The author of Hebrews addresses the issue of priesthood, showing through Old Testament prophecy that Jesus Christ is the ultimate high priest in the order of Melchizedek. Through his argument, three implications of Jesus being a high priest are seen: 1) all priesthood is worthless because of Jesus' work; 2) Christians are no longer under law; and 3) Jesus can rescue people forever. This is a detailed argument seen through fulfilled prophecy spanning hundreds of years, all directly pointing to the finished work of Christ.
