Romans 4:11-12 ▼

11 And he received the sign of circumcision as a seal on the righteousness received through faith while he was uncircumcised. Thus he was to be the father of all the uncircumcised who believe, so that to them [also] righteousness might be credited,

12 as well as the father of the circumcised who not only are circumcised but also follow the path of faith that our father Abraham walked while still uncircumcised.
