The NSRV states at verse 28 that they are enemies for the sake of us Gentiles. What translation are you reading?
No. The NSRV has a very long study note on this point. My physical roots are Italian, Irish, Portugese and French. The metaphor is about the people one's ancestors come from. Same here.
Neither the first fruit nor the root in Romans 11 refer to Jesus but the people of Israel, generally and the patriarchs specifically. These are our spiritual roots.
The whole chapter is about Israel. V 1 opens by asking if God has rejected his people. This is not asking if God has rejected his own Anointed! V 1 continues with Paul NOT saying he is a Christ follower but an Israelite. Finally, he references he's not descended from Christ but Abraham, the patriarch. I believe all your errors in this thread are from being overly-spiritualized, i.e., soulless.
I wouldn't let any comment or thoughts of men suade me from what the Spirit and Word of God reveal.
All the OT offerings and sacrifices were types and shadows of Christ, including the firstfruit offerings:
1Co 15:20
But now is Christ risen from the dead, and become
the firstfruits of them that slept.
1Co 15:23
But every man in his own order:
Christ the firstfruits; afterward they that are Christ's at his coming.
And here we see Christ as the Root:
Isa 11:10
And in that day there shall be a
root of Jesse, which shall stand for an ensign of the people; to it shall the Gentiles seek: and his rest shall be glorious.
Rom 15:12
And again, Esaias saith, There shall be
a root of Jesse, and he that shall rise to reign over the Gentiles; in him shall the Gentiles trust.
Rev 5:5
And one of the elders saith unto me, Weep not: behold, the Lion of the tribe of Juda,
the Root of David, hath prevailed to open the book, and to loose the seven seals thereof.
Rev 22:16
I Jesus have sent mine angel to testify unto you these things in the churches.
I am the root and the offspring of David, and the bright and morning star.
The tree itself is Israel which we have been grafted into, brought near to.....the Israel of God, ie, believing Israel, the kingdom of God, not unbelieving Israel after the flesh.
