Romans 9:7-9 ▼

7 nor because they are seed of Abraham [are] all children, but, “in Isaac will a seed be called to you”;

8 that is, the children of the flesh—these [are] not children of God; but the children of the promise are reckoned for seed;

9 for the word of promise [is] this: “According to this time I will come, and there will be to Sarah a son.”
