Romans 4:9

“What does Scripture say? “Abraham believed God, and it was credited to him as righteousness.””

Contextual; explains the basis of Abraham's justification

“Under what circumstances was it credited? Was it after he was circumcised, or before? It was not after, but before!”

Immediate context; continues the argument about circumcision and justification

“So also Abraham “believed God, and it was credited to him as righteousness.””

Mirrors the language regarding Abraham's faith being credited to him

“And he received circumcision as a sign, a seal of the righteousness that he had by faith while he was still uncircumcised. So then, he is the father of all who believe but have not been circumcised, in order that righteousness might be credited to them.”

Expands on the purpose and meaning of circumcision in relation to faith and justification.

“This righteousness is given through faith in Jesus Christ to all who believe. There is no difference between Jew and Gentile,”

Highlights the universality of justification by faith, applicable to both circumcised and uncircumcised.
