6 But it is not as though the word of God has failed. For not all who are descended from Israel belong to Israel, 7 and not all are children of Abraham ^obecause they are his offspring, but ^p“Through Isaac shall your offspring be named.” 8 This means that it is not the children of the flesh who are the children of God, but ^qthe children of the promise are counted as offspring.

15 For ^pneither circumcision counts for anything, nor uncircumcision, but ^qa new creation.
