Paul sees faith as righteousness.
Connect Genesis 15:6 with Romans 4:3. How does Paul interpret Abraham's faith?

Setting the Scene

- Genesis 15 finds Abram still childless, yet God promises descendants as numerous as the stars (Genesis 15:5).

- In response, “Abram believed the LORD, and it was credited to him as righteousness” (Genesis 15:6).


Genesis 15:6 — The Original Moment of Faith

- Abram’s “believed” is a decisive, heart-level trust in God’s promise, not a general belief in God’s existence.

- “Credited” (Hebrew ḥāšab) is an accounting term: God places righteousness into Abram’s account.

- Nothing in the context shows Abram performing a work to earn this standing; the credit is solely by grace.


Paul’s Use of Genesis 15:6 in Romans 4:3

- Paul quotes verbatim: “For what does the Scripture say? ‘Abraham believed God, and it was credited to him as righteousness’” (Romans 4:3).

- By asking “What does the Scripture say?” Paul treats Genesis as final authority for doctrine, grounding his argument on its literal wording.


Key Observations on Paul’s Interpretation

• Faith versus works

Romans 4:2 contrasts boasting in works with receiving righteousness by faith; Abraham cannot boast.

– Verse 4 underscores that wages are owed to the worker; righteousness is not a wage but a gift.

• Timing of justification

Genesis 15:6 occurs before circumcision (Genesis 17) and centuries before the Law at Sinai, proving God justifies apart from ritual or legal obedience (Romans 4:9–11).

• Nature of faith

– Paul defines faith as “being fully convinced that God was able to do what He had promised” (Romans 4:21).

– This trust rests on God’s power to “call into being what does not yet exist” (Romans 4:17), paralleling the barren womb and the future resurrection of Christ (Romans 4:24–25).

• Universal application

– Because Abraham was counted righteous before circumcision, he becomes “the father of all who believe” (Romans 4:11), whether Jew or Gentile.

• Consistency with the rest of Scripture

Galatians 3:6 cites the same verse to show that “those who have faith are sons of Abraham.”

Ephesians 2:8–9 echoes the principle: salvation is “by grace…through faith…not by works.”


Implications for Us Today

- Salvation rests on trusting God’s promise fulfilled in Christ, not on personal merit.

- Faith is counted as righteousness because it unites the believer to the Righteous One (Philippians 3:9).

- Abraham’s story calls believers to a lifestyle of confident trust, knowing God keeps every promise (2 Corinthians 1:20).
