(Heb 5:8) “Though He were a Son, yet learned He obedience…. (9) And being made perfect, He became the author of eternal salvation unto all them that obey Him; (10) Called of God an high priest after the order of Melchisedec.” There were not perfect High Priest after the order of Aaron, so their representation of sinners was limited. Jesus Christ, being the perfect man, High Priest, after the order of Melchisedec has unlimited representation of those with eternal life!
