Romans 4:10-13

4:10 How then was it credited to him? Was he circumcised at the time, or not? No, he was not circumcised but uncircumcised! 4:11 And he received the sign of circumcision as a seal of the righteousness that he had by faith while he was still uncircumcised, ¹  so that he would become ²  the father of all those who believe but have never been circumcised, ³  that they too could have righteousness credited to them. 4:12 And he is also the father of the circumcised, ⁴  who are not only circumcised, but who also walk in the footsteps of the faith that our father Abraham possessed when he was still uncircumcised. ⁵ 

4:13 For the promise ⁶  to Abraham or to his descendants that he would inherit the world was not fulfilled through the law, but through the righteousness that comes by faith.

¹ tn Grk “of the faith, the one [existing] in uncircumcision.”

² tn Grk “that he might be,” giving the purpose of v. 11a.

³ tn Grk “through uncircumcision.”

⁴ tn Grk “the father of circumcision.”

⁵ tn Grk “the ‘in-uncircumcision faith’ of our father Abraham.”

⁶ sn Although a singular noun, the promise is collective and does not refer only to Gen 12:7, but as D. Moo (Romans 1-8 [WEC], 279) points out, refers to multiple aspects of the promise to Abraham: multiplied descendants (Gen 12:2), possession of the land (Gen 13:15-17), and his becoming the vehicle of blessing to all people (Gen 12:13).
