There's a difference between Israel in a spiritual / biblical sense, and the physical, modern nation state of Israel. The Scofield-inspired view that you are espousing is not the traditional view, in fact it is fairly recent, relatively speaking.
Romans 9:6-8
It is not as though God’s word had failed. For not all who are descended from Israel are Israel. Nor because they are his descendants are they all Abraham’s children. On the contrary, “It is through Isaac that your offspring will be reckoned.” In other words, it is not the children by physical descent who are God’s children, but it is the children of the promise who are regarded as Abraham’s offspring.
Galatians 3:16
Now the promises were made to Abraham and to his offspring. It does not say, “And to offsprings,” referring to many, but referring to one, “And to your offspring,” who is Christ.

Galatians 3:29
And if you are Christ’s, then you are Abraham’s seed, and heirs according to the promise.
Romans 2:28-29
For he is not a Jew who is one outwardly, nor is circumcision that which is outward in the flesh; but he is a Jew who is one inwardly; and circumcision is that of the heart, in the Spirit, not in the letter; whose praise is not from men but from God.
