On the contrary, “It is through Isaac that your offspring will be reckoned.”^{[a](A) 8} In other words, it is not the children by physical descent who are God’s children,^(B) but it is the children of the promise who are regarded as Abraham’s offspring.^{(C) 9} For this was how the promise was stated: “At the appointed time I will return, and Sarah will have a son.”^[b](D)
