Hi Eteranlly-gratefull.
Abrahams seed was ultimatly Christ. This came by way of the Jewish nation Israel, OT History are all types that point to the one true Israel..Christ. That is not to say God does not have a plan for a remnat of Israel. In Abrahams seed all nations are blessed, it is through Christ!
Your argument is based on Dispensational theology that reads the OT into the New rather than correctly reading the OT through the cross!
No concerning your first point:
This is a stretch. And can not be founded in scripture. Paul makes it clear in romans 11 the "National promises" made the "nation of Israel still stand. Again, the only aspect the church has (including jews who are part of the church) is "all the nations shall be blessed through your seed" All the rest is National promises.
To start of with we see that Christ is the true seed :
The promises were spoken to Abraham and to his seed. Scripture does not say “and to seeds,” meaning many people, but “and to your seed,” meaning one person, who is Christ.
(Galatians 3:16)
For if a law had been given that could impart life, then righteousness would certainly have come by the law.
22 But Scripture has locked up everything under the control of sin, so that what was promised, being given through faith in Jesus Christ, might be given to those who believe (Galatians 3:21-22)
So far Paul is telling us that true righteousness comes by Faith not the Law, lets go back to Abraham:
The Call of Abram
1 The LORD had said to Abram, “Go from your country, your people and your father’s household to the land I will show you.
2 “I will make you into a great nation,
and I will bless you;
I will make your name great,
and you will be a blessing.
3 I will bless those who bless you,
and whoever curses you I will curse;
and all peoples on earth
will be blessed through you.”
(Genesis 12)
Then the word of the LORD came to him: “This man will not be your heir, but a son who is your own flesh and blood will be your heir.”
5 He took him outside and said, “Look up at the sky and count the stars—if indeed you can count them.” Then he said to him, “So shall your offspring be.”
6 Abram believed the LORD, and he credited it to him as righteousness. (Gensis 17:4-6)
3 Abram fell facedown, and God said to him,
4 “As for me, this is my covenant with you: You will be the father of many nations.
5 No longer will you be called Abram; your name will be Abraham, for I have made you a father of many nations.
6 I will make you very fruitful; I will make nations of you, and kings will come from you.
7 I will establish my covenant as an everlasting covenant between me and you and your descendants after you for the generations to come, to be your God and the God of your descendants after you.
8 The whole land of Canaan, where you now reside as a foreigner, I will give as an everlasting possession to you and your descendants after you; and I will be their God.” (Genesis 17 3-8)
The Covenant with Abraham not only points to the Jewish nation but to all peoles through Abrahams 'seed' , remember what Paul said in Galatians). Kings will come from him, yes they certainly did.. King David and the Davidic covenant, Christ fulfilled this davidic Kingship. so Abrahams promise is fulfilled as far as that is concerned.
Now we come to tha Land, Abrahams seed will inherit a land. God was calling out for himself a people, and this he did through Abraham, then through the jewish nation as a whole, but now, the true 'seed' that Abraham could only look forward to in marval has arrived, Christ Jesus, and In Christ all nations are blessed, as was told to Abraham he would be a Father of NATIONS, not just nation (read genesis above), In Christ this is true, like Abraham God's children are those of Faith and it is counted to them as righteousness! Not throught the law.
7 Understand, then, that those who have faith are children of Abraham.
8 Scripture foresaw that God would justify the Gentiles by faith, and announced the gospel in advance to Abraham: “All nations will be blessed through you.”
9 So those who rely on faith are blessed along with Abraham, the man of faith. (Galatians 3)
So back to the land, first of all we have to look at Exodus were God Shows the world that He indeed is the one true God, by doing mighty works in Egypt to call his people out of Bondage and slavery, and this he does. God takes them to Sinai and makes a covenant with them. Now this covenant promises all sorts including Land. Yet, this Covenant although similar to the Abrahamic Covenant is different, because in the Abrahamic covenant God took on all the obligations (Genesis 15). The Mosaic covenant is based on if you do this, and this, and this and this, you will live in the land.. the warnings and obligations are stipulated, the Hebrews are placed under obligation to keep the Law. Even still the Law was grace, and this covenant was deeply rooted in the Exodus event itself in the mind of the Hebrews. So the Land was only obligation..they could Loose it.!!! We also have to bear in mind that the Law was a school master it was only temporary (see Galations).
This is why Paul can say that the Law covenant does not anull the Abrahamic covenant :
The Law and the Promise
15 Brothers and sisters, let me take an example from everyday life. Just as no one can set aside or add to a human covenant that has been duly established, so it is in this case.
16 The promises were spoken to Abraham and to his seed. Scripture does not say “and to seeds,” meaning many people, but “and to your seed,” meaning one person, who is Christ.
17 What I mean is this: The law, introduced 430 years later, does not set aside the covenant previously established by God and thus do away with the promise.
18 For if the inheritance depends on the law, then it no longer depends on the promise; but God in his grace gave it to Abraham through a promise.
19 Why, then, was the law given at all? It was added because of transgressions until the Seed to whom the promise referred had come. The law was given through angels and entrusted to a mediator.
20 A mediator, however, implies more than one party; but God is one.
21 Is the law, therefore, opposed to the promises of God? Absolutely not! For if a law had been given that could impart life, then righteousness would certainly have come by the law.
22 But Scripture has locked up everything under the control of sin, so that what was promised, being given through faith in Jesus Christ, might be given to those who believe.
Now read the following very carefully.
Children of God
23 Before the coming of this faith, we were held in custody under the law, locked up until the faith that was to come would be revealed.
24 So the law was our guardian until Christ came that we might be justified by faith.
25 Now that this faith has come, we are no longer under a guardian.
26 So in Christ Jesus you are all children of God through faith,
27 for all of you who were baptized into Christ have clothed yourselves with Christ.
28 There is neither Jew nor Gentile, neither slave nor free, nor is there male and female, for you are all one in Christ Jesus.
29 If you belong to Christ, then you are Abraham’s seed, and heirs according to the promise.
Concerning the OT.
The priests, Kings, Obedience,Temple, Dacidic Kingship -Messianic reign Have all been fulfilled in Christ!
Now that does not resolve the Land issue?
Remember what Paul has already said:
29 If you belong to Christ, then you are Abraham’s seed, and heirs according to the promise.
And all God's people will be called out and when all things are renewed at the end of 'This Age', The 'Age to come' will be the New Jerusalem (The land).
God's people who are heirs according to the promise (Abraham) will inherit the Land!!!! in the Age to come.
