Romans 9:7-9

New International Reader's Version

⁷ Not everyone in Abraham’s family line is really his child. Not at all! Scripture says, “Your family line will continue through Isaac.” (Genesis 21:12) ⁸ In other words, God’s children are not just in the family line of Abraham. Instead, they are the children God promised to him. They are the ones considered to be Abraham’s children. ⁹ God promised, “I will return at the appointed time. Sarah will have a son.” (Genesis 18:10,14)
