TSK · John 8:39

and don’t think you can say to yourselves,‘We have Abraham as our father.’ For I tell you that God can raise up children for Abraham from these stones!

I know that you are Abraham’s descendants. But you want to kill me, because my teaching makes no progress among you.

And he is also the father of the circumcised, 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.

nor are all the children Abraham’s true descendants; rather“through Isaac will your descendants be counted.”

And if you belong to Christ, then you are Abraham’s descendants, heirs according to the promise.
