What does Galatians 4:23 mean?
What is the meaning of Galatians 4:23?

His son by the slave woman

• Paul is recalling Genesis 16, where Abram fathered Ishmael through Hagar, Sarah’s Egyptian servant.

• The slave-mother sets the stage: what begins in bondage produces children who remain in bondage (Galatians 4:24-25).

• Jesus highlights the same principle—“Everyone who sins is a slave to sin” (John 8:34). Our natural lineage and efforts cannot free us.


Was born according to the flesh

• “According to the flesh” points to purely human planning and strength. Abram and Sarai acted on impatience, not on faith (Genesis 16:1-4).

Romans 9:8 echoes Paul’s point: “It is not the children of the flesh who are God’s children, but the children of the promise.”

• Any attempt to secure God’s blessing by human merit mirrors Ishmael’s birth—well-intended but powerless to produce spiritual freedom (Galatians 3:3).


But his son by the free woman

• The “free woman” is Sarah, legally Abram’s wife and never a slave. Freedom is her defining identity (Genesis 17:15-19).

• Just as Sarah was free, the new covenant produces people who are “no longer slaves, but sons” (Galatians 4:7).

• In Christ, believers receive the birthright Isaac enjoyed—full membership in God’s household (John 1:12).


Was born through the promise

• Isaac arrived by supernatural intervention—God restored Sarah’s barren womb long past childbearing age (Genesis 18:10-14; 21:1-2).

Romans 4:18-21 celebrates Abraham’s unwavering trust that “what God had promised, He was able to perform”.

Hebrews 11:11 underscores that Sarah “considered Him faithful who had promised.” God’s promise, not human effort, produced the heir.

• The gospel repeats the pattern: we are “born again…through the living and enduring word of God” (1 Peter 1:23). New life springs solely from divine promise.


summary

• Ishmael represents what human ingenuity can craft; Isaac showcases what only God can create.

• Bondage or freedom, flesh or promise—Paul draws a stark contrast so believers will rest in Christ’s finished work rather than their own striving.

• Just as Isaac’s birth proved God’s word unfailing, every believer’s spiritual birth testifies that the Lord still keeps His promises.
