Galatians 4:22 – “For it is written that Abraham had two sons, one by the slave woman and the other by the free woman.”
Extended Explanation
In this verse, Paul begins an important analogy that explains the difference between living under the law and living by faith. He refers to a well-known Old Testament story about Abraham and his two sons: Ishmael and Isaac.
Abraham’s first son, Ishmael, was born to Hagar, a slave woman. His second son, Isaac, was born to Sarah, Abraham’s wife, who was a free woman. Paul is setting up a contrast between these two sons to make a deeper spiritual point.
- Ishmael represents human effort. He was conceived when Abraham and Sarah tried to “help” God fulfill His promise by using Hagar as a surrogate mother (Genesis 16). This was not God’s plan, but rather a result of impatience and trying to achieve God’s promises through human means.
- Isaac represents God’s promise. He was born miraculously to Sarah when she was well beyond childbearing age, proving that God’s plan comes through faith, not human effort (Genesis 21).
Paul will use this historical event to illustrate a bigger truth: those who try to be right with God by following the law (human effort) are like Ishmael, while those who trust in God’s promise and grace are like Isaac.
Historical Context
Paul was writing to the churches in Galatia, where false teachers known as the Judaizers were trying to convince the Gentile Christians that they needed to follow Jewish laws—especially circumcision—to truly belong to God.
The Judaizers taught that faith in Jesus was not enough; believers also had to obey the law of Moses. Paul was deeply troubled by this because it undermined the gospel message that salvation comes through faith alone.
By bringing up Abraham’s two sons, Paul is reminding the Galatians that God’s promise has always been about faith, not about following religious rules. The story of Isaac and Ishmael is a perfect example of this: Isaac, the child of promise, was born by God’s power, while Ishmael was born through human effort.
Paul wanted the Galatians to see that by trying to rely on the law, they were acting like the descendants of Hagar (slavery) instead of Sarah (freedom).
Theological Implications
This verse introduces a key theological idea: there are only two ways to relate to God—by faith or by works.
- The way of human effort (law/legalism) – Trying to earn salvation through religious rules and traditions. This is represented by Ishmael, who was born through human effort.
- The way of faith (grace) – Trusting in God’s promises and receiving salvation as a free gift. This is represented by Isaac, the child of promise.
Paul’s point is clear: those who rely on the law are choosing slavery, but those who trust in Jesus are living in freedom. God’s promise was never based on human effort but on His grace.
Literary Analysis
Paul introduces a historical story from the Old Testament and uses it as an allegory—a symbolic representation of a deeper spiritual truth.
- The two sons (Ishmael and Isaac) represent two different ways of relating to God.
- The two mothers (Hagar and Sarah) represent two different covenants: one based on the law (Mount Sinai, slavery) and one based on grace (Jerusalem, freedom).
Paul is not saying that the story of Ishmael and Isaac was only symbolic—these events actually happened. But he is showing that they also illustrate a deeper truth about how we relate to God.

What This Verse Means for Today’s Christian
This verse challenges us to think about how we approach our relationship with God.
- Are we trusting in God’s grace, or are we trying to earn His approval through religious effort? Many people fall into the trap of thinking that their good works, church attendance, or following religious rules will make them right with God. But salvation has always been about faith, not works.
- Do we live in freedom or in fear? Ishmael represents a life of striving, while Isaac represents a life of resting in God’s promises. If we are constantly trying to prove ourselves to God, we are missing the joy and peace of the gospel.
How This Verse Relates to a Loving God
God’s love is seen in the way He fulfills His promises. Abraham and Sarah had to wait for many years before Isaac was born, but God was faithful to His word.
This reminds us that God does not need our help to accomplish His plans. He wants us to trust Him rather than rely on our own strength. His love is not based on what we do—it is based on His grace.
Just as God lovingly provided Isaac as the child of promise, He has lovingly provided salvation through Jesus. We do not have to work for it; we simply receive it by faith.
How This Verse Connects to Jesus Christ
Jesus is the fulfillment of the promise that God made to Abraham. In fact, Paul already explained earlier in Galatians that the promise given to Abraham was actually pointing to Christ (Galatians 3:16).
- Jesus is the true child of promise – Just as Isaac was born miraculously, Jesus was born of a virgin by God’s power.
- Jesus sets us free – Just as Isaac was the child of freedom, Jesus came to free us from the burden of the law and sin (John 8:36).
- Through Jesus, we become part of the promise – Just as Isaac was the heir, we become heirs of God’s kingdom through faith in Christ (Romans 8:17).
Paul’s message to the Galatians is the same message for us today: Don’t live like slaves. Live in the freedom that comes through Jesus!
Questions for Reflection and Discussion
- Do you ever find yourself trying to “earn” God’s love through your own efforts?
- What does it mean to live by faith instead of by works?
- How does the story of Ishmael and Isaac help us understand the difference between law and grace?
- Are there areas in your life where you struggle to trust God’s promises?
- How can you remind yourself daily to live in the freedom that Jesus provides?
Galatians 4:22 is a powerful reminder that there are two ways to relate to God—through human effort or through faith in His promises. Paul’s challenge to the Galatians is the same challenge we face today: Will we live in slavery to religious rules, or will we trust in the grace and freedom that Jesus offers?
