TSK · John 8:39

Don't think to yourselves, 'We have Abraham for our father,' for I tell you that God is able to raise up children to Abraham from these stones.

I know that you are Abraham's seed, yet you seek to kill me, because my word finds no place in you.

He is the father of circumcision to those who not only are of the circumcision, but who also walk in the steps of that faith of our father Abraham, which he had in uncircumcision.

Neither, because they are Abraham's seed, are they all children. But, "In Isaac will your seed be called."

If you are Christ's, then you are Abraham's seed and heirs according to promise.
