For it is written that Abraham had two sons, one by a slave woman and one by a free woman.
English Standard Version (ESV)
Paul is addressing Jewish Christians who are tempted to return to observing the Law for their righteousness, rather than relying on faith in Christ. He contrasts the experience of Abraham's two sons, Ishmael born to a slave woman (Hagar) and Isaac born to a free woman (Sarah), to illustrate the difference between being bound by the Law and living in the freedom of God's promise through faith. This ancient story, Paul argues, has a deeper, spiritual meaning that directly applies to their current spiritual situation.
Why does Paul bring up Abraham's sons here? It's not just a family tree, but a picture of two ways of living before God.
Paul uses the story of Abraham's sons, Ishmael and Isaac, to highlight a crucial difference: how we approach God.
Born by the Flesh
Ishmael was born to Abraham and Hagar in the ordinary way – 'after the flesh.' Hagar was a slave, and Ishmael inherited her status. This represents trying to earn God's favor through our own efforts, following rules, and relying on our own strength. It’s a path of bondage.
Born by Promise
Isaac, on the other hand, was born to Abraham and Sarah supernaturally, 'through the promise.' Sarah was Abraham's wife, and Isaac's birth was a miraculous fulfillment of God's word, even when it seemed impossible. This represents receiving God's grace by faith, trusting in His promises and His power to do what we cannot.
Abraham's family wasn't just a historical event; it was a living picture pointing to deeper spiritual realities. Who were these mothers representing?
Paul doesn't just mention Abraham's sons; he unpacks the deeper meaning behind their mothers. It's an allegory, a story with a spiritual meaning.
Hagar: The Earthly Jerusalem
Hagar represents Mount Sinai, where the Old Covenant was given. This covenant, delivered through law, leads to slavery and bondage. It points to the earthly Jerusalem, the city focused on human effort and tradition, which ultimately brings judgment.

Sarah: The Heavenly Jerusalem
Sarah, the free woman, represents the New Covenant, established through God's grace by faith in Christ. This covenant leads to true freedom and inheritance. It points to the 'Jerusalem above,' the heavenly reality of God's people, living by His Spirit.

paidiskē · Greek Noun
A person owned by another, lacking legal freedom or autonomy. In a theological sense, it represents the state of being under the condemnation and bondage of sin and the curse of the law.
Paul uses the well-known story of Abraham's sons, Ishmael and Isaac, to illustrate the difference between those who try to earn God's favor through adherence to the Law (Ishmael's lineage) and those who receive God's promises through faith in Christ (Isaac's lineage).
c. 1890 BC
Birth of Ishmael
Abraham's first son, Ishmael, is born to Hagar, Sarah's Egyptian slave, as a result of Sarah's impatience and plan. This birth occurs outside of God's direct promise for Abraham's lineage.
c. 1870 BC— this verse
Birth of Isaac
God fulfills His promise with the miraculous birth of Isaac to Abraham and Sarah, well past Sarah's natural childbearing years. Isaac is the son of promise and heir.
c. 1850 BC
Hagar and Ishmael Depart
Following Isaac's weaning and a display of mocking by Ishmael, Abraham sends Hagar and Ishmael away at God's direction, separating the 'son of the slave woman' from the heir.
c. 1440 BC
Giving of the Law at Sinai
God gives the Mosaic Law to Israel at Mount Sinai. This event represents the covenant made on the basis of human effort and adherence to the Law, mirroring the 'bondwoman's' condition.
c. 586 BC
Destruction of Jerusalem and Exile
The Babylonians destroy Jerusalem and its Temple, exiling many Israelites. This event signifies the consequences of breaking the covenant and living under the 'law' rather than by faith.
c. 50 years after exile
Return from Exile
A remnant of Israelites returns from Babylonian exile to rebuild Jerusalem and the Temple. While a return to the land, the spirit of dependence on the Law versus faith in God's promise remains a key tension.
c. AD 48
Paul's First Missionary Journey
Paul travels and preaches the gospel, establishing churches in regions like Galatia. During these journeys, he confronts legalistic interpretations of the faith that disregard the freedom found in Christ.
This is the primary narrative account of Ishmael's birth, establishing the foundational detail of Abraham having a son by Hagar, the slave woman.
Genesis 21:2This passage directly records the birth of Isaac to Sarah, Abraham's free wife, thus completing the contrast Paul highlights in Galatians.
Genesis 21:9-10This scripture details Sarah's demand to cast out Hagar and Ishmael, illustrating the tension and separation that arose from their different births and statuses, mirroring the division Paul discusses.
Romans 9:7-13Paul directly parallels the births of Ishmael and Isaac, explaining that 'not all children of Abraham are the children of God,' emphasizing God's sovereign choice in fulfilling His promises through Isaac, not Ishmael.
