What part did none of you understand when it said, "In Isaac your seed shall be called"?
Let's break that verse down for you:
What does Paul mean when he says, "They are not all Israel, which are of Israel"?
Romans 9:6 is frequently misunderstood because people may assume Paul is saying that the Church has become Israel or that Jewish people who reject Jesus are no longer Israelites. Neither conclusion follows automatically from this verse.
Let's examine Paul's words.
Paul distinguishes between physical descent and God's sovereign choice.
Paul begins by addressing a serious question: If God made promises to Israel, have those promises failed because so many Israelites have not accepted Jesus as their Messiah?
Notice the preceding verses.
Romans 9:1–5 (KJV) describes Paul's profound sorrow for his fellow Israelites. In verse 4, he identifies the Israelites as those to whom belong:
- The adoption.
- The glory.
- The covenants.
- The giving of the law.
- The service of God.
- The promises.
In verse 5, he speaks of the fathers and of Christ coming through Israel according to the flesh.
Then Paul writes: "Not as though the word of God hath taken none effect." — Romans 9:6
I
n other words, Paul is saying that Israel's widespread unbelief does not mean God's promises have failed.
His argument concerns God's faithfulness to His promises, not the cancellation of Israel's identity or God's covenant commitments.
"They are not all Israel, which are of Israel."
This statement requires careful interpretation.
Paul is distinguishing between physical descent from Israel and participation in the line of promise through which God was carrying out His covenant purposes.
Consider the patriarchs.
God made promises to Abraham, but Abraham had more than one son.
Ishmael was Abraham's physical descendant, yet God specifically identified Isaac as the son through whom the promised line would continue.
Genesis 21:12 (KJV)
"For in Isaac shall thy seed be called."
Paul quotes this very promise in Romans 9:7.
The point is that physical descent from Abraham alone did not determine which son would carry the particular covenant promise God had given.
This distinction is essential:
God's choice of Isaac over Ishmael did not mean Ishmael ceased to be Abraham's physical descendant. Rather, Isaac was the son through whom the covenant line would continue.
Likewise, the fact that some Israelites do not believe in Christ does not mean they cease to be Israelites by physical descent.
Paul is explaining the distinction between physical ancestry and God's purpose in fulfilling His promises.
What does "the children of the flesh" versus "the children of the promise" mean?
Romans 9:8 states:
"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."
To understand this statement, we must look at the example Paul has just given.
Ishmael and Isaac
Abraham had a son named Ishmael through Hagar, Sarah's servant.
Later, God gave Abraham and Sarah the promised son, Isaac.
Genesis 17:18–21 (KJV)
Abraham asked God to let Ishmael live before Him. God responded by promising to bless Ishmael, make him fruitful, and multiply him.
But God also said: "But my covenant will I establish with Isaac, which Sarah shall bear unto thee at this set time in the next year." — Genesis 17:21
Notice what this passage establishes.
- Ishmael was Abraham's physical son.
- God promised to bless Ishmael.
- God specifically established the covenant line through Isaac.
- Isaac's place in that covenant line rested on God's promise, not merely on physical descent.
Therefore, the expression "children of the flesh" in Romans 9:8 must be understood in the context of Paul's discussion about Abraham's descendants and God's choice of the promised line.
It would be a mistake to conclude that physical descent is meaningless throughout Scripture. God repeatedly identifies Israel by descent from Abraham, Isaac, and Jacob.
It would also be a mistake to conclude that God must fulfill every promise to every descendant in precisely the same way.
God's sovereign choice of Isaac illustrates how He fulfills His promises according to His own purpose.
Paul is not saying that every physical descendant of Israel is excluded from God's salvation.
This is an important distinction. Paul is discussing the relationship between God's promises, Israel's ancestry, and God's sovereign purpose. He is not teaching that Jewish people cannot be saved or that God has permanently rejected the Jewish people.
In fact, Paul directly addresses that question later in Romans.
Romans 11:1 (KJV)
"I say then, Hath God cast away his people? God forbid. For I also am an Israelite, of the seed of Abraham, of the tribe of Benjamin."
Paul's answer is emphatic:
God has not cast away His people.
He identifies himself as an Israelite, a descendant of Abraham, and a member of the tribe of Benjamin.
This is crucial when interpreting Romans 9.
We should not take Paul's statement in Romans 9:6 and use it to reach a conclusion that Paul explicitly rejects in Romans 11:1.
