No. Please read the post you are quoting from in
post # 253 linked. That is not my position at all. Your making arguments no one is arguing about. Therefore your argument is only with yourself here. Isaac is the seed of Abraham who is the father of Israel. I think you missed the point of what the scriptures are saying here. In Romans 9:6-8 Paul is saying that just because you are born of the seed of Abraham does not make one Israel, they are not all Israel that are of Israel. Just because your physically born of the seed of Abraham does not make one truly Israel just as one is born a Jew does not make him a Jew, just as one that has been circumcised does not make one circumcised. A Jew is one inwardly and circumcision is not of the flesh but of the heart through the Spirit. The scriptures do not really need much words added to them perhaps you can prayerfully read them...
Romans 9:6-8 [6], Not as though the word of God has taken none effect. FOR THEY ARE NOT ALL ISRAEL, WHICH ARE OF ISRAEL: [7], NEITHER, BECAUSE THEY ARE THE SEED OF ABRAHAM, ARE THEY ALL CHILDREN: but, In Isaac shall your seed be called. [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.
Galatians 3:28-29 [28], There is neither Jew nor Greek, there is neither bond nor free, there is neither male nor female: for you are all one in Christ Jesus. [29], AND IF YOU BE CHRIST'S, THEN ARE YOU ABRAHAM'S SEED, AND HEIRS ACCORDING TO THE PROMISE.
Romans 2:28-29 [28], For HE IS NOT A JEW, WHICH IS ONE OUTWARDLY; NEITHER IS THAT CIRCUMCISION, WHICH IS OUTWARD IN THE FLESH: [29], But HE IS A JEW, WHICH IS ONE INWARDLY; AND CIRCUMCISION IS THAT OF THE HEART, IN THE SPIRIT, AND NOT IN THE LETTER; whose praise is not of men, but of God.

The name ISRAEL is only a name given by God to those who believe and follow Gods' Word. Jesus would also discuss this with the Jews in His day in the following scriptures which also might be helpful to you here. The Jew made their argument that because they are born of the physical seed of Abraham they therefore are the children of God. Jesus disputes this claim in the following scriptures...
John 8:31-47
[31], Jesus therefore said to those jews that had believed him, if ye continue in my word, then are ye truly my disciples;
[32], and ye shall know the truth, and the truth shall make you free.
[33], They answered unto him,
WE ARE ABRAHAM'S SEED, AND HAVE NEVER YET BEEN IN BONDAGE TO ANY MAN: HOW SAYEST THOU, YE SHALL BE MADE FREE?
[34], Jesus answered them, VERILY, VERILY, I SAY UNTO YOU, EVERY ONE THAT COMMITTETH SIN IS THE BONDSERVANT OF SIN.
[35], And the bondservant abideth not in the house for ever: the son abideth for ever.
[36], IF THEREFORE THE SON SHALL MAKE YOU FREE, YE SHALL BE FREE INDEED.
[37], I KNOW THAT YE ARE ABRAHAM'S SEED: YET YE SEEK TO KILL ME, BECAUSE MY WORD HATH NOT FREE COURSE IN YOU.
[38], I speak the things which I have seen with my Father: AND YE ALSO DO THE THINGS WHICH YE HEARD FROM YOUR FATHER.
[39],
THEY ANSWERED AND SAID UNTO HIM, OUR FATHER IS ABRAHAM. JESUS SAITH UNTO THEM, IF YE WERE ABRAHAM'S CHILDREN, YE WOULD DO THE WORKS OF ABRAHAM.
[40], BUT NOW YE SEEK TO KILL ME, A MAN THAT HATH TOLD YOU THE TRUTH, WHICH I HEARD FROM GOD: THIS DID NOT ABRAHAM.
[41],
YE DO THE WORKS OF YOUR FATHER. THEY SAID UNTO HIM, WE WERE NOT BORN OF FORNICATION; WE HAVE ONE FATHER, EVEN GOD.
[42],
JESUS SAID UNTO THEM, IF GOD WERE YOUR FATHER, YE WOULD LOVE ME: FOR I CAME FORTH AND AM COME FROM GOD; FOR NEITHER HAVE I COME OF MYSELF, BUT HE SENT ME.
[43], Why do ye not understand my speech? Even because ye cannot hear my word.
[44],
YE ARE OF YOUR FATHER THE DEVIL, AND THE LUSTS OF YOUR FATHER IT IS YOUR WILL TO DO. HE WAS A MURDERER FROM THE BEGINNING, AND STANDETH NOT IN THE TRUTH, BECAUSE THERE IS NO TRUTH IN HIM. WHEN HE SPEAKETH A LIE, HE SPEAKETH OF HIS OWN: FOR HE IS A LIAR, AND THE FATHER THEREOF.
[45], But because I say the truth, ye believe me not.
[46], Which of you convicteth me of sin? If I say truth, why do ye not believe me?
[47],
HE THAT IS OF GOD HEARETH THE WORDS OF GOD: FOR THIS CAUSE YE HEAR THEM NOT, BECAUSE YE ARE NOT OF GOD.
.................
Jesus is saying we are not Gods' children because we are born of the seed of Abraham we are the children of God because of what we believe and do that makes us the children of God or the children of the devil.
.................
Conclusion: God's true Israel in the new covenant is simply all those who are born not of the flesh but of the Spirit to believe and follow Gods' Word. Gods' Israel is only a name given by God to all those who believe and follow God's Word. All believers are now one in Christ and gentile believers have been grafted in with Jewish believers who are now Gods' true Israel according to the new covenant scriptures. (
