For the promise to Abraham or to his decendants that he would inherit the world was not through the law, but through the righteousness that comes by faith [Romans 4:13 (HCSB)].
Was (were) Abraham(’s decendants) promised that (t)he(y) would “inherit the world”?! Yes … according to the Holy Spirit (!). Romans 4:13 is the source of such information; nowhere within the Old Covenant Scriptures is any such indication to be found. Despite progressive revelation, multitudes today confine the promises by YHVH [to Abraham (and his seed)] to the physical land of Canaan [disregarding, of course, Joshua 21:43 ("So the LORD gave to Israel all the land of which He had sworn to give to their fathers, and they took possession of it and dwelt in it")]. Jesus’ declaration that “[y]our father Abraham was overjoyed that he would see My day; he saw it, and rejoiced[]” is relegated to a “hard saying of Jesus”.
The Holy Spirit, again via Paul (via his letter to the churches of Galatia), informs us – unequivocally — as to the identity of the beneficiaries of the promises by YHVH [to Abraham (and his seed)]; to wit:
Just as Abraham believed God and it was credited to him as righteousness, so understand that those who have faith are Abraham’s sons. Now the Scripture foresaw that God would justify the Gentiles by faith and foretold the good news to Abraham, saying ‘All the nations will be blessed in you’. So those who have faith are blessed with Abraham, who had faith [Galatians 3:6 - 9 (HCSB)].
Now the promises were spoken to Abraham and to his seed. He does not say ‘and to his seeds,’ as though referring to many, but ‘and to your seed,’ referring to one, who is Christ (v. 16).
And if you are Christ’s, then your are Abraham’s seed, heirs according to the promise (v. 29).
Lamentably, multitudes today insist that we “make God a liar”, simply/ironically because we believe Him (!); their system-driven theology blinds them to crucial Truth. Their Israel-centered hermeneutic has wrought/wreaks church-eviscerating doctrines which Dr. John MacArthur rightly recognized as woeful error and, concomitantly, wrote (decades ago) The Gospel According to Jesus. In response, classical dispensationalists (Dr. Charles Ryrie led the charge), rightly recognizing that doctines such as Jesus’ Lordship are antithetical to dispensationalism, besieged Dr. MacArthur, who then wrote Faith Works/The Gospel According to the Apostles, and proclaimed himself a “leaky dispensationalist”. Dr. MacArthur, of course, adhered and adheres to the Israel-centered hermeneutic — satisfied to be “leaky” — and is today a champion of those who insist that we “make God a liar”. Discouraged but undeterred, we pursue Truth.
We’ve seen that the Writer of Hebrews “sets the table” for the “solid food” (5:12) about to be fed to those with appetite for “solid food” {those upon whom the warning (6:4 - 8 ) is not operative [such warning being operative upon those self-satisfied with "milk" (5:12)]} with “God['s ... ] promise to Abraham” (v. 13). We’ve also seen that we’re to be “imitators of those who inherit the promises through faith and perseverance[]” and that the key to that clause — which ends the sentence which comprises v v. 11 – 12 — is “the promises”.
Because God wanted to show His unchangeable purpose even more clearly to the heirs of the promise, He guaranteed it with an oath, so that through two unchangeable things, in which it is impossible for God to lie, we who have fled for refuge might have strong encouragement to seize the hope set before us [Hebrews 6:17 - 18 (HCSB)].
At p. 168 of The MacArthur New Testament Commentary ~ Hebrews, Dr. MacArthur categorically asserts that “[t]he two unchangeable things are God’s promise and His pledge, His promise and His oath” (emphasis sic). Surprisingly, Edgar Andrews, at p. 182 of A Glorious High Throne [note: For links to any commentary not linked within the instant "post", please see previous "posts" (click link below to The Book of Hebrews or to Jim McDermott)] , concurs, as does Paul Ellingworth, at p. 342 of The New International Greek Testament Commentary: The Epistle to the Hebrews. The broader context, however, indicates otherwise.
The ‘two unchangeable things’ of 6:18 are the two parts of Psalm 110:4, to which the author alludes: ‘You are a priest forever’ and ‘in the order of Melchizedek.’ The allusion as used here begins a transition back to a discussion of Melchizedek in chapter 7. In that chapter the author expounds the two parts of Psalm 110:4 in inverse order:
‘You are a priest forever’ (Heb. 7:15 – 28).
‘In the order of Melchizedek’ (Heb. 7:11 – 14).
Why are these two proclamations by God ‘unchangeable’? In the words of Psalm 110:4, ‘The LORD has sworn and will not change his mind.’ God cannot lie (Heb. 6:18).
George H. Guthrie and Douglas J. Moo, Hebrews, James Zondervan Illustrated Bible Backgrounds Commentary, p. 41.
Dr. Guthrie, via Commentary on the New Testament Use of the Old Testament, G.K. Beale and D.A Carson, eds. (2007, Baker Academic), additionally asks and answers at p. 967:
Why do these two facts give encouragement to those who have fled to God to take hold of hope (6:18 – 19)? Christ has become our high priest according to the order of Melchizedek (6:20) in fulfillment of the psalm’s prophetic oath.
“[T]he promise to Abraham is the theological basis for ultimate fulfillment of that promise in ‘the heirs’ (6:17) — that is, the new-covenant community”. * * * God’s “nature being what it is, therefore, his oaths carry a lasting certainty. Specifically for Hebrews, since God has sworn an oath in the form of Ps. 110:4 (109:4 LXX), therefore, Jesus has become the guarantor or guarantee of a better covenant (7:22), being a ‘permanent’ high priest (7:24). He is the same — yesterday, today, and forever (13:8). This provides strong encouragement for those of the new covenant, because their relationship with God could not be more stable.” Id. at 966.
Thus, believers have fled to take hold of the hope — the ‘horns of the altar’ where atonement has been made for sins through Jesus’ high priestly offering (see also Lev. 16:18 [see Ex. 30:1 - 10]). This hope, therefore, enters ‘behind the curtain’ (6:19) and gives us a place of refuge.
* * *
For the author of Hebrews, the Christian’s hope is to enter the inner sanctuary behind the curtain because that is where Jesus has gone as our high priest. In the old covenant religion, only the high priest could enter the inner sanctuary, and he could do so only once a year on the Day of Atonement. Jesus, however, has entered the true Most Holy Place, heaven, and there intercedes always for us (Heb. 7:25). Thus our hope is made as sure as it could be, Jesus providing a superior, lasting covenant that guarantees our permanent audience with the living God.
Guthrie, Moo at 41 – 42.
“Since the ancient promise is finally fulfilled in Christ, only those can benefit who have fled to Him for salvation.” Andrews at p. 183; Andrews aptly quotes from two hymns (the first, anonymous; the second, Augustus Toplady):
How firm a foundation, ye saints of the lord,
Is laid for your faith in His excellent Word!
What more can He say than to you He has said,
You who unto Jesus for refuge have fled?
Nothing in my hand I bring,
Simply to thy cross I cling.
“The divine kingship and efficacious work of our High Priest is the basis of our security. There can be no greater safety.” Id. at 185. Deo volente, we’ll more closely examine the “solid food” that is the teaching about our Priest/King next time. Again: How’s your appetite?!
