Essay 59: Not All Israel Is Israel
Text: Romans 9:6–9

Introduction

Romans 9:6–9 says, “Not as though the word of God hath taken none effect. For they are not all Israel, which are of Israel: Neither, because they are the seed of Abraham, are they all children: but, In Isaac shall thy seed be called. 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. For this is the word of promise, At this time will I come, and Sara shall have a son.” Paul has just listed Israel’s tremendous privileges: the adoption, the glory, the covenants, the giving of the law, the service of God, the promises, the fathers, and Christ according to the flesh. Then he immediately answers the objection that rises in the mind: if Israel had all those privileges and yet the nation largely rejected Christ, did God’s word fail? Did the promises collapse? Did the covenants run aground? Did God make a plan and then watch it get ruined by Jewish unbelief? Paul answers before the courtroom of history can even finish clearing its throat: “Not as though the word of God hath taken none effect.” God’s word has not failed. Man’s assumptions have failed. That is usually the case.

Romans 9:6–9 is one of the most important passages for keeping a Bible believer from two ditches. On one side is replacement theology, which sees Israel’s unbelief and says, “There, God is finished with the Jews; the Church inherits everything, and Israel can be dismissed.” That is not Paul’s argument. On the other side is racial presumption, which imagines physical descent by itself guarantees spiritual standing before God. Paul rejects that too. He says, “they are not all Israel, which are of Israel.” The statement does not erase Israel; it distinguishes within Israel. It does not turn Israel into the Church; it shows that belonging to the physical nation and belonging to the believing line of promise are not always the same thing. The knife is sharp, but it cuts where the Holy Ghost aims it, not where Gentile theologians or Jewish presumption want it aimed.

The issue is God’s precision. Men tend to think in lumps, slogans, bloodlines, labels, and religious assumptions. God deals according to His word, His promise, His calling, and His purpose. Abraham had more than one son, but God said, “In Isaac shall thy seed be called.” Ishmael was Abraham’s physical seed, but Isaac was the child of promise. That does not make God confused. It proves God was exact from the beginning. The same God who promised Israel and preserved Israel also distinguished promise from mere flesh within Israel’s history. God’s word has not failed because many physical Israelites rejected Christ. The word of God was never governed by man’s broad assumptions in the first place. God’s promises are not a burlap sack where men throw every assumption and call it doctrine. They are a sealed document, and every line means what God wrote.

Chapter One: Not as Though the Word of God Hath Taken None Effect

Paul opens this section with a defense of God’s word: “Not as though the word of God hath taken none effect.” That phrase is the foundation of Romans 9–11. Israel’s unbelief raises a doctrinal question, but Paul refuses to let any man answer it by accusing God’s word of failure. The word of God has not fallen to the ground. The promises have not dissolved. God did not overstate, miscalculate, or lose control. When men look at Jewish unbelief and conclude that God’s promises to Israel failed, they are not interpreting the Bible; they are judging God with a cracked ruler.

This statement also exposes the root problem in much bad theology. Men build an assumption, then blame the Bible when the assumption collapses. They assume every physical Israelite must automatically inherit every spiritual blessing by race alone, and when unbelieving Israel rejects Christ, they think God’s word failed. Or they assume Israel’s unbelief means God canceled Israel and transferred all her promises to the Church, and they call that “spiritual interpretation” because “theft” sounds too honest. Paul says neither. The word of God has not taken none effect. The failure is not in God’s promise but in man’s misunderstanding of how God defined the line of promise.

This is critical because the faithfulness of God is on trial in Romans 9. If God cannot be trusted regarding Israel, why should any believer trust Him regarding Romans 8? If “no condemnation” and “nothing shall separate us” are safe, then God’s promises to Israel must also be handled honestly. God does not keep His word to Gentile believers by breaking His word to Israel. He does not secure the Church by betraying the covenants. Paul’s answer preserves both truths: many Israelites are in unbelief, and God’s word has not failed. A Bible believer does not solve hard doctrine by shaving one truth bald and pretending the other is now clear.

Chapter Two: They Are Not All Israel, Which Are of Israel

Paul says, “For they are not all Israel, which are of Israel.” That sentence is often abused because men love to make it say more or less than it says. It does not mean Israel no longer exists. It does not mean the Church is now Israel in every covenantal sense. It does not mean every promise to national Israel has been evaporated into a spiritual mist and handed to Gentiles. Paul has just said, “Who are Israelites,” in verse 4, speaking of his kinsmen according to the flesh. He knows who Israel is. The statement means that within physical Israel there is a distinction between mere descent and the true line of promise.

“They are not all Israel, which are of Israel” distinguishes the outward national connection from the inward and covenantal reality of God’s promise. A man may be “of Israel” by physical descent and yet not belong to the believing remnant or the line through which God’s saving promise is reckoned. This was not a new idea invented by Paul to explain away a failed plan. The Old Testament already showed Israel as a nation with unbelief inside it, a remnant within it, rebels judged from it, and faithful saints preserved by grace. Elijah thought he was alone, but God had reserved seven thousand who had not bowed the knee to Baal. God has always known the difference between His visible dealings with the nation and the believing remnant according to grace.

The phrase is therefore precise, not destructive. It does not blow up Israel; it separates Bible truth from sloppy assumption. The nation is real. The privileges are real. The covenants are real. The fathers are real. Christ came according to the flesh from Israel. But individual salvation and the line of promise are not guaranteed by mere fleshly descent. A circumcised rebel is still a rebel. A son of Abraham after the flesh still needs the faith of Abraham. A man can have Jewish blood and miss the Jewish Messiah. That is not God’s word failing. That is man discovering that God’s promises never bowed to racial presumption.

Chapter Three: Neither Because They Are the Seed of Abraham, Are They All Children

Paul continues, “Neither, because they are the seed of Abraham, are they all children.” Here the Holy Ghost reaches back to Abraham himself. If physical descent from Abraham automatically made a man heir in the full promised sense, then Ishmael would stand in the same covenantal position as Isaac. But Scripture never says that. Abraham had Ishmael before Isaac. Ishmael was Abraham’s seed according to the flesh. Yet God did not establish the covenant through Ishmael. Genesis 17:19 says, “Sarah thy wife shall bear thee a son indeed; and thou shalt call his name Isaac: and I will establish my covenant with him.” God made the distinction before Paul ever wrote Romans.

That demolishes fleshly boasting. The Jews of Paul’s day could say, “We be Abraham’s seed,” as they did in John 8:33, but the Lord Jesus told them that if they were Abraham’s children in the spiritual sense, they would do the works of Abraham. Physical descent had privilege, responsibility, and historical importance, but it did not regenerate the heart. It did not justify the sinner. It did not make unbelief into faith. Abraham himself was justified by faith before circumcision, as Romans 4 already proved. Therefore the children who truly stand in the promise must be connected to the promise by faith, not merely by bloodline.

Paul’s point is not that Abraham’s physical seed means nothing. That would contradict the entire passage. His point is that physical seed alone does not settle the issue of promise. God’s dealings are more exact. Abraham’s house itself proves it. Ishmael was real. Ishmael had a future as a nation. God heard Abraham concerning Ishmael and blessed him in a temporal sense. But Isaac was the covenant child. Isaac was the promised seed. Isaac came by God’s word and God’s power when Abraham and Sarah’s bodies testified that nature could not produce the promise. Flesh can produce Ishmael. Only God’s promise can produce Isaac.

Chapter Four: In Isaac Shall Thy Seed Be Called

Paul quotes the decisive word: “but, In Isaac shall thy seed be called.” That statement is from Genesis 21:12, where God told Abraham not to let the matter of Ishmael and Isaac be settled by sentiment. God said, “in Isaac shall thy seed be called.” Isaac was not chosen because he was stronger, older, more impressive, more natural, or more convenient. Ishmael was older. Ishmael looked like the obvious heir if men were running the program. But God’s promise did not follow man’s obvious choice. God called the seed through Isaac.

“In Isaac” is a doctrinal boundary marker. It shows that God’s promise narrows according to His word. Abraham has seed, but the called seed is Isaac. Later Isaac has Jacob and Esau, and Paul will continue the argument. God’s line of promise is not determined by human assumption, natural order, outward appearance, or fleshly claim. It is determined by God’s word. That is why Romans 9 cannot be reduced to human bloodline alone or turned into Gentile replacement theology. God is showing His exactness within Israel’s history. He is not canceling Israel; He is explaining how promise operates inside Israel’s own beginnings.

The quotation also reminds us that Scripture interprets history. Men look at Abraham’s family and may think, “Surely all Abraham’s sons are equal in the covenant line.” God says no. Men look at Israel and may think, “Surely every physical Israelite is automatically saved.” God says no. Men look at Israel’s unbelief and may think, “Surely God is done with the nation.” God says no again. Human logic without Scripture is a blind man drawing maps. God’s statement, “In Isaac shall thy seed be called,” teaches that the promise is neither as broad as fleshly presumption nor as canceled as replacement theology imagines. It is exact.

Chapter Five: Children of the Flesh and Children of God

Paul explains, “That is, They which are the children of the flesh, these are not the children of God.” That sentence must be handled with care. “Children of the flesh” in this immediate context refers to physical descent considered apart from the promise. Ishmael was born after the flesh in the sense that his birth was produced through human scheme and natural means, not through the supernatural promise given concerning Sarah. Galatians 4:23 says of Abraham’s two sons, “he who was of the bondwoman was born after the flesh; but he of the freewoman was by promise.” Paul is using the same doctrinal contrast here.

To be a child of the flesh is not enough. That is a thunderclap against every religion that trusts heritage, ritual, culture, nation, family name, church membership, sacramental record, or ancestral privilege. The flesh can inherit a name, but it cannot inherit regeneration. The flesh can receive a circumcision mark, but it cannot produce a circumcised heart. The flesh can boast in Abraham, Moses, temple, law, and fathers, but it cannot make itself righteous before God. Romans has already concluded both Jew and Gentile under sin. Fleshly identity may increase privilege, but it cannot erase guilt. A sinner with a religious pedigree is still a sinner.

Yet again, Paul is not teaching that Gentiles replace Israel. He is teaching that the children of God are not determined by flesh alone. Israel’s own history proves it. God distinguishes promise from mere natural descent. That truth also prepares the reader for the doctrine of the remnant. Within national Israel there are those who truly believe, those who belong to the line of promise, those who receive God’s word by faith. God’s work has never depended on the mass approval of unbelieving men. A whole crowd can have the right blood and the wrong heart. God is not fooled by a birth certificate when the soul rejects His Son.

Chapter Six: The Children of the Promise Are Counted for the Seed

Paul says, “but the children of the promise are counted for the seed.” There is the positive side. God counts the children of the promise for the seed. The issue is not mere biological connection, but promise. Isaac existed because God promised him. Sarah was barren. Abraham was old. Nature had no power to bring the promised son into the world. God spoke, and the promised child came. That is the pattern Paul uses. Promise, not flesh, determines the counted seed.

“Counted” is an important word. Romans has already used the language of reckoning, imputing, and counting in connection with Abraham’s faith. Romans 4:3 says, “Abraham believed God, and it was counted unto him for righteousness.” Now Romans 9 says the children of the promise are counted for the seed. God’s accounting is not governed by human pride. He counts according to promise. Men can count bodies, bloodlines, rituals, tribes, ceremonies, and outward claims. God counts according to His word. When God opens the books, fleshly arithmetic loses its swagger.

This also keeps the doctrine from becoming either racialism or replacement. The “children of the promise” language does not deny God’s promises to Israel; it explains how God’s promise line was always distinguished by God’s word. Isaac was the child of promise within Abraham’s physical household. Later, the believing remnant will stand within Israel according to grace. Gentiles are blessed through Abraham’s Seed, which is Christ, and are saved by faith in this present dispensation, but that does not make the Church a thief of Israel’s national covenants. God can save Gentiles, preserve a Jewish remnant, and still keep future promises to national Israel without asking a theologian’s permission.

Chapter Seven: At This Time Will I Come, and Sara Shall Have a Son

Paul concludes the example: “For this is the word of promise, At this time will I come, and Sara shall have a son.” The birth of Isaac rested on a specific word from God. “At this time will I come.” God set the time. God named the mother. God promised the son. Sarah shall have a son. Not Hagar. Sarah. Not Ishmael. Isaac. Not the child produced by human impatience. The child produced by divine promise. God’s work was not vague, mystical, symbolic fog. It was exact enough to name the woman, the child, and the time.

This word of promise exposes the foolishness of trying to help God with fleshly substitutes. Abraham and Sarah had already produced Ishmael through human scheming. But Ishmael did not become the covenant child because man rushed ahead. The flesh can produce activity, religion, movements, systems, and impressive results, but it cannot manufacture the promise of God. Many religious systems are Ishmael factories: busy, noisy, impressive, and born from human effort trying to accomplish divine ends without waiting on God’s word. Isaac comes when God says, through the woman God named, in the time God appointed.

The phrase “Sara shall have a son” also protects the historical reality of the promise. Paul’s doctrine is built on actual events in Genesis. Abraham was real. Sarah was real. Isaac was real. Ishmael was real. The promise was real. The distinction was real. The Bible’s doctrine rests on God’s acts in history, not religious myths floating in the clouds. God’s dealings with Israel are rooted in real promises made to real people, fulfilled in real ways, and used by the Holy Ghost to teach exact doctrine. Men who spiritualize everything until nothing means what it says are not deeper than the text. They are less obedient to it.

Conclusion

Romans 9:6–9 answers the charge that God’s word has failed because many physical Israelites rejected Christ. Paul says, “Not as though the word of God hath taken none effect.” The failure is not in God’s word. The failure is in man’s assumption that physical descent alone guarantees participation in the promise in its fullest saving sense. They are not all Israel, which are of Israel. That statement distinguishes within Israel; it does not abolish Israel. It corrects fleshly presumption without handing Israel’s covenants to replacement theology.

The example of Isaac proves God’s precision. Abraham had more than one son, but God said, “In Isaac shall thy seed be called.” Ishmael was Abraham’s seed according to the flesh, but Isaac was the child of promise. The children of the flesh are not counted as the children of God merely because of physical descent. The children of the promise are counted for the seed. That truth runs through Israel’s history and prepares the reader to understand the remnant, the nation’s present unbelief, and God’s future faithfulness. God’s program is not as broad as human presumption and not as canceled as Gentile arrogance imagines.

Romans 9:6–9 therefore strengthens confidence in the word of God. God has not lost control of Israel. God has not broken His covenants. God has not allowed unbelief to ruin His purpose. He has always dealt according to promise, calling, and His own exact word. The same God who said Sarah would have a son brought Isaac into the world at the appointed time. The same God who distinguished Isaac from Ishmael knows exactly how to distinguish promise from flesh, remnant from rebellion, and truth from religious assumption. God’s promises do not need man’s help, man’s edits, or man’s excuses. The word of God has not failed. It is man’s sloppy theology that keeps tripping over the text.
