I would rather we simply discuss the Scriptural texts than speculate on what motives the other is operating by and towards.
Then I suggest that you discuss them in context so as to avoid applying them to concepts foreign to the theses of the document.
And I was not speculating. I am confident that you are aware that here are many strange teachings which are purported to be based on some snippet of scripture.
why and in what context is Paul quoting Isaiah on the saving of the remnant to return to the promised land from various pagan nations on earth?
The context of Romans 9 is provided by Paul in the opening verses of the chapter. (1 through 9)
I
am speaking the truth in Christ, I am not lying; my conscience bears me witness in the Holy Spirit, that I have great sorrow and unceasing anguish in my heart. For I could wish that I myself were accursed and cut off from Christ for the sake of my brethren, my kinsmen by race. They are Israelites, and to them belong the sonship, the glory, the covenants, the giving of the law, the worship, and the promises; to them belong the patriarchs, and of their race, according to the flesh, is the Christ. God who is over all be blessed for ever. Amen.
But it is not as though the word of God had failed. For not all who are descended from Israel belong to Israel, and not all are children of Abraham because they are his descendants; but "Through Isaac shall your descendants be named." This means that it is not the children of the flesh who are the children of God, but the children of the promise are reckoned as descendants.
What is the promise?
Gen 22:17-18
I will indeed bless you, and I will multiply your descendants as the stars of heaven and as the sand which is on the seashore. And your descendants shall possess the gate of their enemies, and by your descendants shall all the nations of the earth bless themselves, because you have obeyed my voice.
Unless a remnant of faithful had returned to Judea, the descendants of Israel would have been absorbed into the pagan nations. There would have been no Jewish messiah born in Bethlehem.
How does it fit in right after the calling unto salvation (
Rom 9:24) and right before faith unto salvation (
Rom 9:30)?
Paul answers that.
Rom 9:3-31
What shall we say, then? That Gentiles who did not pursue righteousness have attained it, that is, righteousness through faith; but that Israel who pursued the righteousness which is based on law did not succeed in fulfilling that law.
Salvation has always been based in faith. The Law of Moses didn't promise NT "salvation"; it promised that, if Israel kept the law, it would go well with them and they would live long in the promised land. (Deu 5:33) There wasn't a word about the eternal life offered to all who would believe in the New Covenant.
Paul is explaining that being a descendant of Abraham and having received the Law meant nothing to a person who did not have faith in God.
I hope we can agree upon the fact that the phrase "Election of grace" in
Rom 11:5 means that the Election was on the basis of the grace of God and not on the works of men (
Rom 11:6).
Salvation comes only by the grace of God. God is under no necessity to save anyone but He has graciously chosen to give eternal life to whoever believes in Jesus and keeps His commands as best he can. Salvation would not exist without God's grace and man would not be blessed with salvation without exercising faith and practicing faithfulness.
This ties in to the previous
Rom 11:5 reference to election of grace too.
All salvation is by grace and according to God's gracious will. But the 5th verse of Rom 11 does not stand by itself.
Rom 11:1-5
I ask, then, has God rejected his people? By no means! I myself am an Israelite, a descendant of Abraham, a member of the tribe of Benjamin. God has not rejected his people whom he foreknew. Do you not know what the scripture says of Eli'jah, how he pleads with God against Israel? "Lord, they have killed thy prophets, they have demolished thy altars, and I alone am left, and they seek my life." But what is God's reply to him? "I have kept for myself seven thousand men who have not bowed the knee to Ba'al." So too at the present time there is a remnant, chosen by grace.
What remnant is chosen by grace? (not "of" grace, but "by" grace) The remnant that remained faithful. Who else would God elect? The rebellious and apostate? Certainly not.
I believe your basing God's grace on what Jacob and Esau would do, is explicitly refuted in
Rom 9:11
Rom 9:6-11
But it is not as though the word of God had failed. For not all who are descended from Israel belong to Israel, and not all are children of Abraham because they are his descendants; but "Through Isaac shall your descendants be named." This means that it is not the children of the flesh who are the children of God, but the children of the promise are reckoned as descendants. For this is what the promise said, "About this time I will return and Sarah shall have a son." And not only so, but also when Rebecca had conceived children by one man, our forefather Isaac, though they were not yet born and had done nothing either good or bad, in order that God's purpose of election might continue, not because of works but because of his call,..
And what was God's purpose?
It was that out of the tribe of Judah would come the son of Abraham, the son of Isaac, the son of Jacob, the son of David, the son of Mary who is the Son of God.
It was not whether either child had done anything but that Esau would not produce the line which led to Jesus and, therefore could not be used for God's purpose. Jacob would produce that line, thereby fulfilling God's purpose, and, therefore, he was chosen.
God's purposes in election is not based on man's good or evil works but on God who calls.
Men's good or evil works do not qualify or disqualify anyone to be used by God for His purposes. Even the man who strives all his life to do good works is not by those works qualified. (Luke 17:10
So you also, when you have done all that is commanded you, say, "We are unworthy servants; we have only done what was our duty.")
God's election is based on God's purposes and His purpose is that whoever calls on the name of the Lord will be saved. (Act 2:21, Rom 10:13)
