Romans 4:11
He received the sign of circumcision as a seal [confirming] that he had been [considered] righteous because of the faith he had before being circumcised. Thus, he became the [spiritual] father of all people who believe [in God], even though they have not been circumcised, so that they could be considered righteous [by their faith].
Romans 4:19-20
Abraham's faith did not become weak [even though] he was about one hundred years old and considered his body almost dead and Sarah's womb incapable of conceiving a child.
