And he received the sign of circumcision [as] a seal of the righteousness by faith which [he had] {while uncircumcised}, so that he could be the father of all who believe {although they are uncircumcised}, so that righteousness could be credited to them,

and the father {of those who are circumcised} to those who are not only from the circumcision, but who also follow in the footsteps of the faith of our father Abraham {which he had while uncircumcised}.

and being fully convinced that what he had promised, he was also able to do.

What then shall we say? [Is] the law sin? May it never be! But I would not have known sin except through the law, for I would not have known covetousness if the law had not said, "Do not covet."

But [it is] not as if the word of God had failed. For not all those [who are descended] from Israel [are truly] Israel,

for [although they] had not yet been born, or done anything good or evil, in order that the purpose of God according to election might remain,

And just as Isaiah foretold, "If the Lord of hosts had not left us descendants, we would have become like Sodom and would have resembled Gomorrah."
