Romans 9:7-8

9:7 nor are all the children Abraham’s true descendants; rather “through Isaac will your descendants be counted.” 9:8 This means it is not the children of the flesh who are the children of God; rather, the children of promise are counted as descendants.

Romans 9:25-26

9:25 As he also says in Hosea:

“I will call those who were not my people, ‘My people,’ and I will call her who was unloved, ‘My beloved.’”

9:26 “And in the very place where it was said to them, ‘You are not my people,’

there they will be called ‘sons of the living God.’”
