Foundation Text

Genesis 15:6

Hebrew Key Terms

• H0539 אָמַן (aman) - believed, trusted, had faith
• H2803 חָשַׁב (chashab) - counted, reckoned, imputed
• H6666 צְדָקָה (tsedaqah) - righteousness

Context: After promising Abram innumerable descendants like the stars, the LORD declares His heir will come from Abram's own body. Abram's response of faith becomes the paradigmatic statement of justification by faith alone, cited three times in the NT (Rom 4:3; Gal 3:6; Jas 2:23).

OT-to-OT Development

• This verse establishes the foundational principle that righteousness comes through faith, not works
• Later OT texts presuppose this principle (Hab 2:4: "the righteous will live by faith")
• The Abrahamic covenant of promise (Gen 12:1-3; 15:1-21; 17:1-27) precedes Sinai by 430 years (Gal 3:17)
• Psalms celebrate those who trust in the LORD (Ps 32:1-2, linked to Gen 15:6 in Rom 4:6-8)

Connections

  • Genesis 12:1-3 - Abrahamic promise of blessing to all nations
• FROM OT:
  • Habakkuk 2:4 - righteous by faith shall live
  • Psalm 32:1-2 - blessedness of forgiveness
• FROM NT:
  • Romans 4:3, 9, 22 - Paul's doctrine of justification
  • Galatians 3:6 - Abraham justified by faith
  • James 2:23 - faith proved by works

Christological Connection: Abraham believed God's promise of a seed through whom all nations would be blessed (Gen 12:3; 22:18). Paul identifies this singular "seed" as Christ (Gal 3:16). The righteousness imputed to Abraham by faith is not a shadow of the gospel's righteousness but the same gift received the same way: the righteousness of God revealed in the gospel through faith in Christ (Rom 3:21-26) is credited to believers exactly as it was credited to Abraham (Rom 4:23-24). All who believe in Christ are Abraham's true offspring, heirs of the promise (Gal 3:29).

Connection Method(s): Promise-Fulfillment, Longitudinal Theme — God's promise of a seed through whom all nations would be blessed finds fulfillment in Christ (Galatians 3:16), and the faith-righteousness first stated here runs through the canon to the gospel (Romans 4; Galatians 3). Abraham is not a type of the new-covenant believer but a direct exemplar of faith-righteousness: the Abrahamic and new covenants are administrations of the one covenant of grace, so what was credited to Abraham is credited in the same way to all who believe in Christ, with no shadow awaiting escalation.
