Commentary on Romans 4

Romans 4 is Paul's masterful demonstration that the pattern of salvation has always been by faith alone, not by works of the law. He takes his Jewish readers back to their founding father, Abraham, and shows from Genesis 15:6 that Abraham was counted righteous before he was circumcised and before the Law was given. Paul then extends the argument to David, who also understood that forgiveness is a gift, not a wage. The chapter dismantles any claim that human effort earns God's favor and establishes faith as the only instrument through which we receive the righteousness of Christ. It is the Old Testament foundation for the New Testament doctrine of justification by faith.

Historical context

Paul writes to a church in Rome composed of both Jewish and Gentile believers. The Jewish Christians, steeped in the Old Testament, naturally revered Abraham as the patriarch and prototype of covenant membership. Many assumed that circumcision and Torah-observance were essential to being part of God's people. Paul must show them that Abraham himself — the man before circumcision and before the Law — was justified by faith alone.

The broader context is Paul's argument from Romans 3:21-31 that God's righteousness is available through faith in Christ apart from the Law. Now in chapter 4, he provides the scriptural proof. He cites Genesis 15:6 and Psalm 32:1-2, both of which speak of a righteousness that is credited, not earned. The Greek verb logizomai (λογίζομαι), meaning "to count" or "to credit," appears eleven times in this chapter and is the theological engine of the passage. Paul is doing what any good rabbi would do: he is showing that the Law and the Prophets testify to the gospel.

Verse by verse

• 1:

  Paul asks what Abraham, the father of the Jewish nation, discovered concerning justification. The question is rhetorical, designed to force the reader to consider Abraham's own experience rather than later traditions about him.

• 3:

  Paul quotes Genesis 15:6 directly: "Abraham believed God, and it was counted to him as righteousness." The Greek verb elogisthē (ἐλογίσθη) is an accounting term — it means to credit something to someone's account. Abraham did not produce righteousness; he received it by believing God's promise.

• 4:

  Paul draws a sharp contrast between a wage and a gift. If justification were earned by works, it would be an obligation — something God owes. But the gospel announces a grace that is freely given, not a debt that is paid.

• 5:

  This verse is the heart of the chapter. The one who does not work but trusts God who justifies the ungodly has his faith counted as righteousness. The object of faith is not faith itself, but God — specifically, the God who justifies sinners, not the righteous.

• 6:

  Paul adds David as a second witness. In Psalm 32, David speaks of the blessedness of the person whose sin is covered and not counted against him. This is the same imputation language: righteousness is credited, not achieved.

• 9:

  Paul asks whether this blessing is for the circumcised only or also for the uncircumcised. He notes that Abraham was counted righteous in Genesis 15, but circumcision was not commanded until Genesis 17. Chronology proves that justification precedes and is independent of the sign of the covenant.

• 11:

  Circumcision is redefined as a seal of the righteousness that Abraham already had by faith. He becomes the father of all who believe — both circumcised Jews who follow his faith and uncircumcised Gentiles who walk in the same path of faith.

• 13:

  The promise to Abraham and his offspring that he would inherit the world did not come through the Law but through the righteousness of faith. The Law, which came 430 years later, cannot add to or alter a promise that was already given by grace.

• 16:

  Paul concludes that the promise rests on grace and is guaranteed to all Abraham's offspring — not only those who have the Law (Jews) but also those who share the faith of Abraham (Gentiles). Faith is the only way the promise can be both gracious and certain.

• 17:

  Abraham believed in the God who gives life to the dead and calls into existence the things that do not exist. This is the kind of God we trust — one whose power is not limited by natural impossibility. Abraham's faith was resurrection-shaped before the resurrection even happened.

• 18:

  Against all hope, Abraham hoped in God's promise that he would become the father of many nations. His body was as good as dead (he was about 100 years old), and Sarah's womb was barren. Yet he did not waver in unbelief.

• 22:

  Paul returns to the refrain: "That is why his faith was counted to him as righteousness." The entire chapter has been building to this point — that the pattern of Abraham's faith is the pattern for all believers.

• 23:

  Paul makes a stunning move. The words "it was counted to him" were not written for Abraham's sake alone, but for ours. The Old Testament was written for the instruction of the New Testament church.

• 24:

  Righteousness will be counted to us who believe in him who raised from the dead Jesus our Lord. The content of our faith is the same as Abraham's: trust in the God who raises the dead. Abraham trusted God for a son from a dead womb; we trust God for life from a dead tomb.

• 25:

  This verse is a dense summary of the gospel. Jesus was delivered up for our trespasses and raised for our justification. His death paid the penalty; his resurrection vindicated his work and secured our standing. The two events are inseparable in the work of salvation.

Key themes

• Justification by faith alone
• Imputed righteousness
• Abraham as the father of all believers
• Grace versus works
• Faith in the God who raises the dead

Application

Romans 4 frees us from the exhausting treadmill of trying to earn God's approval. If Abraham, the father of the faith, was counted righteous simply by believing God's promise, then we can stop pretending we need to bring something to the table. The gospel announces that God credits Christ's righteousness to our account the moment we trust him — not because we are good, but because he is gracious.

This chapter also expands our family. Abraham is not just the father of Israel; he is the father of everyone who walks in the footsteps of faith. That means every believer — regardless of background, ethnicity, or religious pedigree — is a true child of Abraham. The church is a multi-ethnic family united not by blood or ritual, but by trust in the same promise-making, promise-keeping God.

Finally, Paul calls us to a faith that looks like Abraham's: hope against hope, trust in the God who raises the dead. When our circumstances scream impossibility, faith remembers that God calls into existence things that do not exist. The same power that gave Isaac to Abraham and raised Jesus from the tomb is at work for us.
