I have never seen a dispensationalist-Christian Zionist interpretation of Galatians 3: 3, 16, 26-29. They always ignore it and/or bring up some other text.
How is taking New Testament texts to mean what they plainly state applied to Romans 11: 25-26? "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, until the fulness of the Gentiles be come in.
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:"
The dispensationalist-Christian Zionists will say the meaning of Romans 11: 25-26 that when the fullness of the Gentiles happens, or all the Gentiles God intends to save are saved, then all Israel will be saved. Or all living at that time, or some living at that time.
But this interpretation is inconsistent with Romans 9: 6-8, "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 thy 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."
In verse 6, the "plain" interpretation might be that Paul is saying there are two Israels. That is not what he is teaching because he says in verse 8 that they who are children of the flesh are not the children of God. There is just one Israel, which he in verse 8 calls the children of the promise, counted as the seed.
This meaning in Romans 9: 6-8, that the children of the flesh, by which he means those of Old Covenant Israel who claim to be the physical descendants of Abraham and are not born again in Christ are not the children of God, is supported by II Corinthians 3:6-11. There Paul talks about the ministration of death which is the same as the ministration of condemnation in this text and the ministration of the spirit or the ministration of righteousness. He says in verse 11 that the ministration of condemnation is done away with. Just as the children of the flesh are not the children of God - in Romans 9: 6-8 - so the ministration of death-condemnation, which is the Old Covenant, is not of God.
Galatians 4: 24-26 also agrees with the interpretation of Romans 9: 6-8 that the children of the flesh - Old Covenant Israel without Christ - are not the children of God. There Israel of the flesh, called Jerusalem which now is, is in bondage with her children, but the Jerusalem (Israel) which is above, is free, and is the mother of us all. Clearly, the Jerusalem which is the mother of us all, refers to Israel as being the mother of all the elect of God. Of course, dispenationalism-Christian Zionism, which here can be called separation theology, claims God now has two peoples, Old Covenant Israel and the Church.
Galatians 3: 3, 16, 26-29 also supports that interpretation. Galatians 3: 16 focuses on the covenant with Abraham in Genesis 17, by saying that "Now to Abraham and his seed were the promises made. He saith not, And to seeds, as of many; but as of one, And to thy seed, which is Christ." Galatians 3: 16 also focuses upon Genesis 13: 16, that Abraham would have many descendants, or seed, and on Genesis 26: 4, where the same promise of many seed is given to Issac and on Genesis 28: 14 where the promise of many seed is also given to Jacob.
And then Paul says "For ye are all the children of God by faith in Christ Jesus.
27. For as many of you as have been baptized into Christ have put on Christ.
28. There is neither Jew nor Greek, there is neither bond nor free, there is neither male nor female: for ye are all one in Christ Jesus.
29. And if ye be Christ's, then are ye Abraham's seed, and heirs according to the promise."
This is subtle. Paul does not say in an explicit way that the physical bloodline from Abraham does not exist in the New Covenant. For dispenstionalist-Christian Zionists to understand what Paul is saying in Galatians 3, that is exactly what the text would have to say for it to be understood by some of these people.
But in saying in Galatians 3: 26-29 that all who have faith in Christ are the children of God, and whether they are Greeks or Jews does not matter, because everyone who is Christ's is the seed of Abraham, Paul is implying with certainty that the physical bloodline from Abraham does not determine who is Christ's and who is the seed of Abraham.
