Romans 4:11-12,16
And he received the sign of circumcision, a seal of the righteousness that he had by faith while he was still uncircumcised.
So then, he is the father of all who believe but have not been circumcised, in order that righteousness might be credited to them. And he is also the father of the circumcised who not only are circumcised but who also walk in the footsteps of the faith that our father Abraham had before he was circumcised ...
Therefore, the promise comes by faith, so that it may be by grace and may be guaranteed to all Abraham’s offspring – not only to those who are of the Law but also to those who are of the faith of Abraham. He is the father of us all.
Romans 11:3-5
“Lord, they have killed Your prophets and torn down your altars; I am the only one left, and they are trying to kill me”?
And what was God’s answer to him? “I have reserved for Myself seven thousand who have not bowed the knee to Baal.”
So too, at the present time there is a remnant chosen by grace.
