God's Love Will Not Fail, Part 2

6But it is not as though the word of God has failed. For not all who are descended from Israel belong to Israel, 7and not all are children of Abraham because they are his offspring, but Through Isaac shall your offspring be named. 8This means that it is not the children of the flesh who are the children of God, but the children of the promise are counted as offspring. 9For this is what the promise said: About this time next year I will return, and Sarah shall have a son. 10And not only so, but also when Rebekah had conceived children by one man, our forefather Isaac, 11though they were not yet born and had done nothing either good or badin order that God's purpose of election might continue, not because of works but because of him who calls 12she was told, The older will serve the younger. 13As it is written, Jacob I loved, but Esau I hated. 14What shall we say then? Is there injustice on God's part? By no means! 15For he says to Moses, I will have mercy on whom I have mercy, and I will have compassion on whom I have compassion. 16So then it depends not on human will or exertion, but on God, who has mercy. 17For the Scripture says to Pharaoh, For this very purpose I have raised you up, that I might show my power in you, and that my name might be proclaimed in all the earth. 18So then he has mercy on whomever he wills, and he hardens whomever he wills.
