Verses 1-5: Abraham’s Justification by Faith. Paul begins by questioning how Abraham was justified, concluding that it was not by works but by faith, which is credited as righteousness. He contrasts works, which earn a debt, with faith, which receives grace.
Verses 6-8: David’s Testimony on Forgiveness. Paul supports his argument by citing David’s words about the blessedness of those whose sins are forgiven and to whom God imputes righteousness apart from works.
Verses 9-12: Faith Before Circumcision. The discussion turns to whether this blessing is limited to the circumcised, showing that Abraham was justified by faith before circumcision, making him the father of all who believe, circumcised or not.
Verses 13-17: The Promise Through Faith, Not Law. Paul explains that the promise to Abraham and his heirs is based on faith, not the law, because the law brings wrath and cannot grant the promise. Abraham is the father of all who believe.
Verses 18-22: Abraham’s Unwavering Faith. Paul describes Abraham’s faith as strong and hopeful despite natural impossibilities, fully trusting God’s promise which was credited to him as righteousness.
Verses 23-25: Application to Believers in Christ. Finally, Paul applies Abraham’s example to believers today, stating that righteousness is imputed to those who believe in God who raised Jesus from the dead, who was delivered for our sins and raised for our justification.
