Our blessed Lord was to be "a High Priest after the order of Melchizedec." It will be remembered that Melchizedec met Abraham returning from the slaughter of the kings, and blessed him (Gen. 14:19). In the same way our great High Priest blesses the seed of Abraham; for "they which be of faith are blessed with faithful Abraham;" and as believers in the Lord Jesus Christ, they walk in his steps who "believed God, and it was counted unto him for righteousness."
But Melchizedec the type could only ask God to bless Abraham. He could not himself confer the blessing; but Jesus, the antitype, our great Melchizedec, whose priesthood is "after the power of an endless life," blesses his people, not by merely asking God to bless them, but by himself showering down blessings upon them, and by communicating to them out of his own fulness every grace which can sanctify as well as save. Even before his incarnation, when he appeared in human form, as if anticipating in appearance that flesh and blood which he should afterwards assume in reality, he had power to bless.
Thus we read that when Jacob wrestled with the angel, which angel was no created angel, but the Angel of the covenant, even the Son of God himself in human shape, he said, "I will not let thee go except thou bless me." And in answer to his wrestling cry we read that "he blessed him there." Jacob knew that no created angel could bless him. He therefore said, when he had got the blessing, "I have seen God face to face, and my life is preserved." To this blessing Jacob afterwards referred when, in blessing Ephraim and Manasseh, he said, "The angel which redeemed me from all evil bless the lads."
Thus, also, our gracious Lord, immediately before his ascension to heaven, as if in anticipation of the gifts and graces which he was to send down upon them when exalted to the right hand of the Father, "lifted up his hands and blessed his disciples;" and as if to shew that he would still ever continue to bless them, "he was parted from them and carried up into heaven," even "while he blessed them," as if he were blessing them all the way up to heaven, even before he took possession of his mediatorial throne (Luke 24:50, 51).
