With whom was the Abrahamic Covenant made? Only with Abraham, Isaac and Jacob. These last two received the Abrahamic promises not through their relationship to Abraham, but directly from God (Gen 26:2-5; 28:12-15). The covenant is made with no one else. If I believe that God is going to make a great nation out of me, or make me a blessing to all nations, or give my descendants the Land of Canaan as a possession, I am more than likely to be deceiving myself. Nor could an Israelite appropriate the promises to himself; any of Abraham’s descendants other than Isaac and Jacob might be childless. But when we place our faith in the promised Seed, we may appropriate the promised blessing as we become a child of Abraham by faith (Gal 3:7) and inherit the heavenly country that Abraham sought and found (Heb 11:15-16). The covenant ‘with Abraham, Isaac and Jacob’ is repeatedly mentioned in Scripture (Exod 2:24; 32:13; Lev 26:42; Num 32:11; 2Kings 13:23; 1Chron 16:16ff; Psalm 105:9 etc.) but no one else is ever spoken of as being in the covenant with them.
Rom 9: I say the truth in Christ, I lie not, my conscience also bearing me witness in the Holy Ghost,
2 That I have great heaviness and continual sorrow in my heart.
3 For I could wish that myself were accursed from Christ for my brethren, my kinsmen according to the flesh:
4 Who are Israelites; to whom pertaineth the adoption, and the glory, and the covenants, and the giving of the law, and the service of God, and the promises;
5 Whose are the fathers, and of whom as concerning the flesh Christ came, who is over all, God blessed for ever. Amen.
You are not living in reality, Martin. The covenants of promise ware made with this whole family who were the "children of Israel." This Abrahamic covenant has not been revoked because of Israel's sins but is an everlasting covenant. God has bound himself under an oath to bring every promise of it to pass, including making of Israel a great nation in the promised land grant. Abraham, Isaac, and Jacob will live in a resurrected body in the new earth which is physical. Whatever Israel's claim on the land grant given by God in the Covenant he made with Abraham and confirmed to Isaac and Jacob is legitimate and eternal.
Romans 9 was written by Paul the apostle in 58 AD, 28 years after he had poured out his promise of the Spirit on Israel in Acts 2 and 18 years after he poured out the Spirit on gentiles in Acts 10. In this 9th chapter of Romans we learn that in the providence of God that the physical seed of Abraham were divided into two parts and that those many who would not believe in Jesus Christ were distinct from those few who believed and became the children of God by the new birth.
Rom 9:6 Not as though the word of God hath taken none effect. For they are not all Israel, which are of Israel: (circumcision in the flesh as ID is now replaced by the Spirit in the heart to identify Israel)
7 Neither, because they are the seed of Abraham, are they all children: but, In Isaac shall thy seed be called. (this means the family of God MUST come through Isaac instead of all the other sons of Abraham who became great families and nations)
8 That is, They which are the children of the flesh, these are not the children of God: but the children of the promise are counted for the seed.
Remember we read in Galatians that the Law ended at the cross of Christ and faith began.
Paul then accuses Israel of falling short of God's salvation by insisting on holding on to the law while excluding faith as their expression of following God. This holds Israel completely responsible for the Jews being broken off and replaced by grafted in gentiles. You men hold God responsible for what happens next but it is the providence of God that directed history to reach his intended end..
Ro 10:1 Brethren, my heart s desire and prayer to God for Israel is, that they might be saved.
2 For I bear them record that they have a zeal of God, but not according to knowledge.
3 For they being ignorant of God s righteousness, and going about to establish their own righteousness, have not submitted themselves unto the righteousness of God.
4 For Christ is
the end of the law for righteousness to every one that believeth.
Remember God's sworn oath to keep the Abrahamic covenant. He must save Israel as a people and give them the land he promised to them to dwell in.
But not during this age.
The context from Romans 7:1 through Romans 11:12 had been to Jews and proselytes. In Romans 11:13 and following he is addressing gentiles in context. It will help your understanding if this is noted.
Romans 11 tells us how God is going to keep the hope of Israel alive through the very small remnant of believers in Christ called the "remnant according to the election of grace," and fashion the church from both Jew and gentile believers, a heavenly entity. When this family is complete then the purge from the earth of all unbelievers during the great tribulation and the deliverance of the few who are left when all Israel will finally be saved without any more remnant. The importance of Ro 11 cannot be overemphasized.
Ro 11:25 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, (
how long?) until the fulness of the Gentiles be come in.
What then?
(remember, written to gentile believers).
26
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:
27 Fo
r this is my covenant unto them, when I shall take away their sins.
28 As concerning the gospel, they are enemies for your sakes: but as touching the election, they are beloved for the fathers sakes.
29 For the gifts and calling of God are without repentance.
30 For as ye in times past have not believed God, yet have now obtained mercy through their unbelief:
31 Even so have these also now not believed, that through your mercy they also may obtain mercy.
32 For God hath concluded them all in unbelief, that he might have mercy upon all.
Believe the words and note the context and you will be safe.
