Romans 9:7

Neither, because they are the seed of Abraham, are they all children: but, In Isaac shall thy seed be called.

Romans 9:7 (KJV)

Context

In Romans 9, the apostle Paul addresses a pressing question: has God’s word to Israel failed? Many of his fellow Jews had not accepted Jesus as the Messiah, which seemed to contradict God’s promises to Abraham. Paul answers that God’s promises have not failed, because not all physical descendants of Abraham are truly his children in the spiritual sense.

Paul draws on the account of Abraham in Genesis. God made a covenant with Abraham, promising to make him a great nation and to bless him with numerous descendants. Abraham had two sons: Ishmael, born through Sarah’s maidservant Hagar, and Isaac, born through Sarah by God’s supernatural intervention. In Genesis 21:12, God tells Abraham to listen to Sarah, because “in Isaac shall thy seed be called.” Paul quotes this directly in Romans 9:7 to show that the line of promise runs through Isaac, not through Ishmael or any other physical descendant.

Meaning

The verse makes a crucial distinction between physical descent and spiritual inheritance. Being a biological descendant of Abraham does not automatically make someone a child of God or an heir of the covenant promises. Paul states plainly: “Neither, because they are the seed of Abraham, are they all children.” Ishmael was Abraham’s son, but he was not the child through whom the covenant line would continue.

The phrase “In Isaac shall thy seed be called” reveals that God’s purposes operate through promise and divine choice, not merely through natural lineage. Isaac was the child of promise, born through God’s miraculous intervention when Sarah was old. This shows that God’s covenant is established by His word and His sovereign will, not by human effort or ancestry.

Biblical connections

Paul develops this idea further in Romans 9:8, where he explains that “the children of the flesh” are not the children of God, but “the children of the promise” are counted as the seed. This principle is not limited to the Old Testament. In Galatians 3:26-29, Paul teaches that in Christ, both Jews and Gentiles become children of God through faith, and thus are heirs of the Abrahamic covenant. The true children of Abraham are those who share his faith, not merely his bloodline.

Application

This verse challenges any assumption that religious heritage or family background guarantees a right relationship with God. Just as being a physical descendant of Abraham was not enough, being raised in a Christian home or belonging to a church does not make someone a child of God. What matters is faith in Jesus Christ, who is the ultimate fulfillment of the promise to Isaac. Through faith, believers from every nation become part of the spiritual seed of Abraham.

Reflection

God’s sovereign choice in calling Isaac reminds us that salvation is not earned by human merit or inherited by natural birth. It is a gracious gift, rooted in God’s promise and His faithful word. This should lead us to humility and gratitude, recognizing that we are included in God’s family only because of His mercy. It also encourages us to trust that God’s purposes never fail, even when circumstances seem to contradict His promises.
