I was going one step further and referred to the statement that not Israel is Israel.It seems to me that Paul is still addressing the anticipated question in verse 1.
Rom 11:1
11:1 I say then, has God cast away His people?
NKJV
And sharing his desire in vs. 14...
Rom 11:14
14 if by any means I may provoke to jealousy those who are my flesh and save some of them.
NKJV
I'm glad we agree.
