All dispensationalists are liars too!
And if ye be Christ’s, then are ye Abraham’s seed, and heirs according to the promise. Gal. 3:29
Well I don't know about other "MADs" on here, as they might hold a different view on some of that than the MADs outside of TOL that I find I share an understanding with on many things.
But my understanding of Galatians 3 is that...
Christ had been of Abraham's physical seed.
But this issue is a spiritual one.
And if ye be Christ's - which is a spiritual union - then you are also of Abraham's spiritual seed - according to the promise.
Thing is, just what was that promise?
And just how is it that a Gentile is made an heir of that promise?
And what is Paul talking in light of?
In light of the fact that whatever said promise had been; it had been before the Law with its Performance Based Acceptance, was temporarily added to that promise.
Also, Paul is actually talking about Gentiles not only in Abraham spiritually, but before Abraham was in Circumcision, or back when he too had been...a Gentile.
And all that "spiritual" is, is the issue of Abraham's same...having believed God...when he too had been in...Uncircumcision.
It was back then - when Abraham was in Uncircumcision - that God said to him that in him - in his seed: Christ - all the families of the Earth would be blessed.
And Abraham believed Him; and his having believed Him, was counted for righteousness...based on the coming merit of The Cross.
That is the promise - Christ Himself "the blessing of Christ."
And that is the case - Christ Himself is that promise - He is the Promise, both within that which was Prophesied about Him throughout the OT as to Israel, as well as now, this side of Israel's fall and temporary setting aside, and with that, God's revealing of the preaching of Jesus Christ according to the revelation of the Mystery, which in contrast to that which was Prophesied, was kept secret since the world began, but now was being made manifest - the preaching of, or concerning God's New Creature in Christ: the Body of Christ.
Romans 4 and Romans 8 share this connection with Galataians 3 and Galatians 6, but as a result of Romans 3, in light of Romans 9 thru 11, not in light of Isaiah 60 and Isaiah 66, which are on hold; Romans 9.
Galatians 3:1 O foolish Galatians, who hath bewitched you, that ye should not obey the truth, before whose eyes Jesus Christ hath been evidently set forth, crucified among you? 3:2 This only would I learn of you, Received ye the Spirit by the works of the law, or by the hearing of faith? 3:3 Are ye so foolish? having begun in the Spirit, are ye now made perfect by the flesh?
3:6 Even as Abraham believed God, and it was accounted to him for righteousness.
Galatians 5:2 Behold, I Paul say unto you, that if ye be circumcised, Christ shall profit you nothing. 5:3 For I testify again to every man that is circumcised, that he is a debtor to do the whole law. 5:4 Christ is become of no effect unto you, whosoever of you are justified by the law; ye are fallen from grace. 5:5 For we through the Spirit wait for the hope of righteousness by faith.
Galatians 6:15 For in Christ Jesus neither circumcision availeth any thing, nor uncircumcision, but a new creature.
Acts 17:11, 12.
