8 In other words, it is not the children by physical descent who are God’s children, but it is the children of the promise who are regarded as Abraham’s offspring.
9 For this was how the promise was stated:‘At the appointed time I will return, and Sarah will have a son.’
10 Not only that, but Rebekah’s children were conceived at the same time by our father Isaac.
11 Yet, before the twins were born or had done anything good or bad – in order that God’s purpose in election might stand:
12 not by works but by him who calls – she was told, ‘The older will serve the younger.’
13 Just as it is written: ‘Jacob I loved, but Esau I hated.’
14 What then shall we say? Is God unjust? Not at all!
