Yes, and this is super salesman Paul both reassuring the Christian converts from Judaism that their friends and relations who have not converted still have God's promise of salvation, and the pagan converts that they are just as validly saved as are the Jews - the People of God. This letter was written before the full fledged split of Christianity from Judaism - where the Jews finally got tired of this new religion kidnapping and redefining much of their religion and repudiated them completely. And, with the past 2000 years of history validating that judgement.
Please note that the concept of adopting in Gentiles is a completely NT idea and not in the OT at all. Nothing in Deuteronomy or anywhere else says that God will bring in anyone else, only that He will use the gentile nations as tools on the lives and situation of the Jewish nation. So linking Deuteronomy and Paul's epistle to the Romans is not really valid.
For ye have heard of my conversation in time past in the Jews' religion, how that beyond measure I persecuted the church of God, and wasted it: And profited in the Jews' religion above many my equals in mine own nation, being more exceedingly zealous of the traditions of my fathers. But when it pleased God, who separated me from my mother's womb, and called [me] by his grace, To reveal his Son in me, that I might preach him among the heathen; immediately I conferred not with flesh and blood: Neither went I up to Jerusalem to them which were apostles before me; but I went into Arabia, and returned again unto Damascus.
Then after three years I went up to Jerusalem to see Peter, and abode with him fifteen days. But other of the apostles saw I none, save James the Lord's brother. Galatians 1:11-19
And so all Israel shall be saved: as it is written, There shall come out of Sion the Deliverer, and shall turn away ungodliness from Jacob: For this [is] my covenant unto them, when I shall take away their sins.
As concerning the gospel, [they are] enemies for your sakes: but as touching the election, [they are] beloved for the fathers' sakes. Romans 11:25-28
Thou wilt say then, The branches were broken off, that I might be graffed in.
Well; because of unbelief they were broken off, and thou standest by faith. Be not highminded, but fear: For if God spared not the natural branches, [take heed] lest he also spare not thee.
Behold therefore the goodness and severity of God: on them which fell, severity; but toward thee, goodness, if thou continue in [his] goodness: otherwise thou also shalt be cut off.
And they also, if they abide not still in unbelief, shall be graffed in: for God is able to graff them in again.
For if thou wert cut out of the olive tree which is wild by nature, and wert graffed contrary to nature into a good olive tree: how much more shall these, which be the natural [branches], be graffed into their own olive tree?
For I would not, brethren, that ye should be ignorant of this mystery, lest ye should be wise in your own conceits; that blindness in part is happened to Israel, until the fulness of the Gentiles be come in.
And so all Israel shall be saved: as it is written, There shall come out of Sion the Deliverer, and shall turn away ungodliness from Jacob: For this [is] my covenant unto them, when I shall take away their sins.
As concerning the gospel, [they are] enemies for your sakes: but as touching the election, [they are] beloved for the fathers' sakes.
For the gifts and calling of God [are] without repentance. - Romans 11:18-29
God's Name is I AM.
You are right, Mark. Gentiles are addressed in reference to Noah. They are subject to seven Noahide laws, but outside of those they have no other obligation or duty in God's plan. Knowing the God of Noah and Abraham as the light of the nations is not the same as being "grafted" or "tasked" to pick up where the Jews failed.
The Jews, and no one else, are clearly the people God chose in the Bible to serve him. Nowhere in OT do you find that the Gentiles will be tasked to take over the duty of serving God in place if Israel. That is another Pauline innovation.
In reading your point you state among other things: "...So linking Deuteronomy and Paul's epistle to the Romans is not really valid." Now with all due respect to kosta, he has repeated stated that he does not agree with Paul and that he doesn't believe in the Old/New Testament as the inspired word of God and that errors exists. So that makes me wonder, why would you call kosta to defend your position? Given these two issues, our friend kosta seems to me to be the last person you would want to call to discuss a Paulinian linkage of Romans to Deuteronomy.
Is this trying to throw mud in the waters?
