In Hebrews chapter four, verses 1-10, the author discusses Jesus' appointment by God as a high priest after the order of Melchizedek. This reference to a somewhat obscure character from the book of Genesis has far-reaching significance. Jesus was not from the priestly line of Aaron, yet He was designated a high priest by God Himself. And because He was sinless, He was able to offer the perfect sacrifice – Himself – becoming the source of eternal salvation.
