“Now consider how great this man was, unto whom even the patriarch Abraham gave the tenth of the spoils. “- Hebrews 7:4

Consider how great Melchizedek was. There is something majestic about every movement of that dimly-revealed figure. His one and only appearance is thus fitly described in the Book of Genesis,-“And Melchizedek king of Salem brought forth bread and wine: and he was the priest of the most high God. And he blessed him, and said, Blessed be Abram of the most high God, which hath delivered thine enemies into thy hand. And he gave him tithes of all.” We see but little of him, yet we see nothing little in him. He is here and gone, as far as the historic page is concerned, yet is he “a priest for ever,” and “it is witnessed that he liveth.” Everything about him is on a scale majestic and sublime.

Beloved friends, if Melchizedek was so great, how much greater is that man whom Melchizedek represents! If the type is so wonderful what must the Antitype be! I invite you to consider “how great” is He of whom it is written, “The Lord sware and will not repent, Thou are a priest forever after the order of Melchizedek.” I will not say “Consider how great this man was”, for there is no verb: the “was” is inserted in italics by the translators. We are to consider “how great this man.” Say “was” if you will, but read also “is,” and “shall be.” Consider how great this man was and is, and is to be, even the Man Christ Jesus. ~ C,H. Spurgeon
