Really?
Jacob, the individual, wasn't chosen? Only a future nation was chosen?
I would argue that the entire story of Jacob in Genesis is about a wicked child whom God graciously chose, despite his wickedness.
Certainly a nation comes from Jacobs lineage and specifically, a promised Redeemer comes from Jacob's lineage, which establishes an eternal Kingdom. But, Jacob is most certainly chosen as an individual as well.
Why are you so bent on trying to run around this truth? Is it because you refuse to give up the theology you have created?
You like David are ignorant of the scriptures. You read in to it what it does not support.
This is not individual.
Gen 25:21 And Isaac intreated the LORD for his wife, because she was barren: and the LORD was intreated of him, and Rebekah his wife conceived.
Gen 25:22 And the children struggled together within her; and she said, If it be so, why am I thus? And she went to enquire of the LORD.
Gen 25:23 And the LORD said unto her,
Two nations are in thy womb,
and two manner of people shall be separated from thy bowels; and the one people shall be stronger than the other people; and the elder shall serve the younger.
Gen 25:24 And when her days to be delivered were fulfilled, behold, there were twins in her womb.
Gen 25:25 And the first came out red, all over like an hairy garment; and they called his name Esau.
Gen 25:26 And after that came his brother out, and his hand took hold on Esau's heel; and his name was called Jacob: and Isaac was threescore years old when she bare them.
No where here is this choosing individual. Nor in romans 9 is it ever shown as individual Show me what makes you think this is individual? The embolded above makes it cooperate. This is settled you and David have lost.
