Romans 4 Bible Study: Abraham Was Justified by Faith

By
Elizabeth Kim

Romans 4 is Paul’s case study on how a person is made right with God. He points to Abraham, the father of Israel, and asks whether Abraham earned his standing through works or received it by believing God. Readers come to this chapter because it answers a question that runs through Christian life: how does a sinner stand before a holy God, and does faith or effort make the difference?

Romans 4 Summary

Paul opens by asking what Abraham gained through his own efforts. If Abraham had been declared righteous because of what he did, he would have grounds for boasting, but not before God. Paul then turns to Scripture to show that Abraham’s faith was credited to him as righteousness, which means the matter was settled by trust, not by a ledger of good deeds.

From there Paul widens the scope. He brings in David’s words about the blessing of forgiven sin, then shows that Abraham was counted righteous before he was circumcised. That sequence matters because it means the promise was not tied to the Jewish law or to the sign of circumcision alone. Paul concludes that Abraham is the father of all who believe, Jew and Gentile alike.

The chapter ends by describing the kind of faith Abraham had. He believed God’s promise of descendants even when his body and Sarah’s womb seemed unable to produce a child. Paul then applies this to his readers: God raised Jesus from the dead, and those who believe in him are counted righteous on the same basis.

Background and Setting

Paul wrote the letter to the Romans around AD 56 to 58, most likely from Corinth during his third missionary journey. The church in Rome included both Jewish and Gentile believers, and tensions between the two groups over the law and identity seem to shape much of the letter. Paul had not yet visited Rome when he wrote, though he hoped to go there on his way to Spain.

Chapter 4 sits in the argument section of the letter, after Paul has explained that all people, Jew and Gentile, fall short of God’s glory and that righteousness comes through faith in Christ. Here he steps back and shows that this principle is not new. The Old Testament itself, in the story of Abraham, already teaches that God credits righteousness through faith.

Romans 4 Section by Section

Verses 1-8: The Blessing of Being Counted Righteous

3 For what does the Scripture say? “Abraham believed God, and it was accounted to him for righteousness.” 4 Now to him who works, the reward is not counted as grace, but as something owed. 5 But to him who doesn’t work, but believes in him who justifies the ungodly, his faith is accounted for righteousness.

Romans 4:3-5 (WEB)

Paul begins with a question about Abraham, the one Jews honored as their founding ancestor. He quotes Genesis to show that Abraham believed God and it was credited to him as righteousness. The key contrast is between wages and gift. A worker is paid what he has earned, but a person who trusts God receives something he could never earn.

Paul then brings in David, who wrote of blessing for those whose sins are forgiven and covered. David is not describing someone who has accumulated merit. He is describing a person who has received mercy. Paul uses this to show that the blessing of righteousness has always been a matter of forgiveness received by faith, not payment rendered by works.

Verses 9-12: Faith Before Circumcision

9 Is this blessing then pronounced on the circumcised, or on the uncircumcised also? For we say that faith was accounted to Abraham for righteousness. 10 How then was it counted? When he was in circumcision, or in uncircumcision? Not in circumcision, but in uncircumcision. 11 He received the sign of circumcision, a seal of the righteousness of the faith which he had while he was in uncircumcision, that he might be the father of all those who believe, though they might be in uncircumcision, that righteousness might also be accounted to them.

Romans 4:9-11 (WEB)

Paul now asks whether this blessing belongs only to the circumcised. His answer depends on timing. Genesis records that Abraham’s faith was credited to him before he received circumcision. Circumcision came afterward as a sign and seal of a righteousness he already had.

That order carries weight for a divided church. If Abraham was declared right with God before he was circumcised, then circumcision cannot be the entry point into God’s family. Abraham becomes the father of all who believe, including Gentiles who have never been circumcised, and also the father of Jewish believers who walk in the same faith.

Verses 13-17: Promise Through Faith, Not Law

13 For the promise to Abraham and to his offspring that he should be heir of the world wasn’t through the law, but through the righteousness of faith. 14 For if those who are of the law are heirs, faith is made void, and the promise is made of no effect. 15 For the law produces wrath, for where there is no law, neither is there disobedience.

Romans 4:13-15 (WEB)

The promise to Abraham was that he would inherit the world and that his offspring would be blessed. Paul insists that this promise did not come through the law given centuries later at Sinai. It came through the righteousness that faith receives. If inheritance depended on keeping the law, faith would be empty and the promise would collapse, because no one can keep the law perfectly.

Paul adds that the law brings wrath because it reveals sin and makes disobedience plain. Faith, by contrast, rests on God’s grace. Because the promise depends on grace rather than performance, it is sure for all of Abraham’s offspring, both those who have the law and those who share Abraham’s faith.

Verses 18-22: Abraham’s Hope Against Hope

18 Besides hope, Abraham in hope believed, to the end that he might become a father of many nations, according to that which had been spoken, “So will your offspring be.” 19 Without being weakened in faith, he didn’t consider his own body, already having been worn out, (he being about a hundred years old), and the deadness of Sarah’s womb. 20 Yet, looking to the promise of God, he didn’t waver through unbelief, but grew strong through faith, giving glory to God, 21 and being fully assured that what he had promised, he was also able to perform.

Romans 4:18-21 (WEB)

Paul paints a vivid picture of Abraham’s trust. Humanly speaking there was no reason to expect a child. Abraham was nearly a hundred years old, and Sarah’s womb was dead. Yet Abraham did not deny these realities. He looked at them honestly and still held to God’s word, giving glory to the God who gives life to the dead.

The faith Paul describes is not a denial of difficulty. It is a steady confidence that God is able to do what he has promised. Abraham grew stronger in faith as he looked to God rather than to his own strength, and this is why Paul says his faith was credited to him as righteousness.

Verses 23-25: Faith in the Risen Christ

23 Now it was not written that it was accounted to him for his sake alone, 24 but for our sake also, to whom it will be accounted, who believe in him who raised Jesus, our Lord, from the dead, 25 who was delivered up for our trespasses, and was raised for our justification.

Romans 4:23-25 (WEB)

Paul closes by applying Abraham’s story to his readers. The account of Abraham was written for our sake too, to show that righteousness is credited to those who believe. The object of that faith is God who raised Jesus our Lord from the dead.

Jesus was handed over for our trespasses and raised for our justification. Paul links the cross and the resurrection together: the first deals with sin, and the second declares that the work is complete and that believers stand accepted before God.

Key Themes in Romans 4

  • Justification by faith: God counts a person righteous because they trust him, not because they have earned his approval.
  • Grace versus works: Paul contrasts a wage that is owed with a gift that is freely given, and places salvation firmly in the second category.
  • Abraham as father of all believers: Abraham’s faith before circumcision makes him the ancestor of both Jewish and Gentile believers.
  • Hope in God’s promise: Abraham trusted God’s word even when every natural sign pointed the other way.
  • The resurrection and justification: Jesus was raised so that those who believe in him can be declared righteous.

Lessons From Romans 4 for Today

Many believers carry an unspoken sense that they must keep up their standing with God through constant effort. Romans 4 invites a different posture. When you lie awake wondering whether you have done enough to be accepted, Paul reminds you that righteousness is credited through trust in the risen Christ, not earned through a flawless record.

The chapter also speaks to church divisions. Paul refused to let one group’s background or practice become the measure of belonging, because Abraham was righteous before the sign was given. When a dispute in your small group or congregation turns on who is really in, Romans 4 points you back to the faith that unites all believers.

Finally, Abraham’s hope offers encouragement in long waiting. A couple praying for a child, a family watching a loved one suffer, or someone who has waited years for a promise to take shape can see in Abraham a model of honest trust. He did not pretend the obstacles were gone, but he kept looking to the God who gives life to the dead.

Questions for Reflection

  • Where in your life do you still try to earn God’s acceptance, and what would change if you received it as a gift?
  • How does Abraham’s faith before circumcision shape the way you think about who belongs in God’s family?
  • What promise from God are you waiting on right now, and how might Abraham’s example guide your waiting?
  • In what ways does the resurrection of Jesus give you confidence that your sins have been dealt with?

A Prayer From Romans 4

Lord, I confess that I often try to measure my worth by what I have done and how well I have done it. Thank you that you do not count me righteous because of my performance, but because I believe in you who raised Jesus from the dead. Help me rest in that gift today, especially when I feel I have failed or fallen behind. Give me Abraham’s kind of faith, one that looks honestly at my circumstances and still gives glory to you. Strengthen my trust in your promises, and let my life show that I belong to you through grace alone. Amen.

Frequently Asked Questions

What is the main point of Romans 4?

Romans 4 shows that people are declared righteous before God through faith, not through works or the law. Paul uses Abraham as the leading example, since Abraham’s faith was credited to him before he was circumcised. The chapter presents this as the pattern for all believers.

Why does Paul bring up Abraham in Romans 4?

Abraham was the founding ancestor of Israel and the figure Jewish readers most respected. By showing that Abraham was justified by faith rather than works, Paul demonstrates that his teaching is rooted in the Old Testament itself. This helps unite Jewish and Gentile believers under a common foundation.

What does it mean that Abraham’s faith was credited as righteousness?

To credit something means to count it or record it to someone’s account. Abraham’s trust in God was counted as the standing he needed before God, even though he had not yet earned it by works. Paul says this same kind of crediting applies to everyone who believes in Christ.
