Romans 4:11-12

Context
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
