Not however as though the word of God had failed; for not all [are] Israel which [are] of Israel;
nor because they are seed of Abraham [are] all children: but, In Isaac shall a seed be called to thee. a8
That is, [they that are] the children of the flesh, these [are] not the children of God; but the children of the promise are reckoned as seed.
For this word [is] of promise, b According to this time I will come, and there shall be a son to Sarah. c10
And not only [that], but Rebecca having conceived by one, Isaac our father,
[the children] indeed being not yet born, or having done anything good or worthless (that the purpose of God according to election might abide, not of works, but of him that calls),
it was said to her, d The greater shall serve the less:
according as it is written, e I have loved Jacob, and I have hated Esau.
What shall we say then? [Is there] unrighteousness with God? Far be the thought.
For he says to Moses, f I will shew mercy to whom I will shew mercy, and I will feel compassion for whom I will feel compassion.
So then [it is] not of him that wills, nor of him that runs, but of God that shews mercy.
