Romans 11 clearly says God has not cast away Israel (vs. 1, 19); but
because of Israel's unbelief (vs. 20) and blindness (vs. 7-10), God broke off branches so that the Gentiles world ciuld be grafted in.
He has a Covenant with them, has not cast them away and so their blindness continues until the fullness (numbers) of the Gentiles is complete (vs. 25). That happens at this moment: Matt. 24:14. Then an Israel will be saved (vs. 26).
12k from each tribe (Rev. 7) - and only God knows who they are. Scripture specifically names each tribe. This is not to be taken symbolically, this is literal. Also they are male virgins (Rev. 14) and this is only part of the Jews, whose veils will be lifted.
It is her clear, the distinction made between Israel ( the bloodline of the tribes) and the Christian Gentiles.
A remnant (5 million Jews) will come to Christ during the GT. Every eye will see Him and they will mourn.
"God broke off branches so that the Gentiles world
could be grafted in..." I had not thought it that way before, even as I had thought blindness of Israel
in part (v 25) meant part or some of them, but not all. Here, however, we have blindness happening to ALL of natural Israel, that Gentiles might be graffed in (v19).
And so ALL of the old covenant, priesthood, and law of Moses was done away to bring in the New Covenant, priesthood, and law of Christ. (Heb 7:12, 8:13)
As well as, ALL the old natural people of the covenant and promises made to the fathers were broken off to bring in
ALL new creatures of God, "..
.old things are passed away; behold, all things are become new...of God." (2 Cor 5:17, 18) (Amen brother, that is new to me)
This agrees with John Baptist (Matthew 3:12) that God's tree of Covenant, would be
thoroughly pruned (Luke 3:17) from ALL the old natural branches,
that He might bring in the new
former wild ones (Christians are not 'wild ones' anymore:)) Hence the admonition to the newly grafted not to boast against the newly broken off, for God is able to graft the natural branches back in again (v 23), (
to the New Vine (John 15)). For the new branches can likewise be broken off and not spared (v 21).
I truly thank you for your correction and instruction, you have added to me (Prov 9:9)
However (

), I do not believe your assertion that natural Israel and Israelites
were not cast away, but rather were not cast away
forever.
1. The natural Israelite branches clearly were broken off. (v 17), which reads to me that natural Israel was cast away. Scriptural proof, or an alternative reasoning would be necessary to say the 2 are different. (I do not believe an original languages parsing would be sufficient here).
Or, there must be a distinction between 'Israel' and 'natural branches', as in nation of vs individual in...
2. Either way, you certainly stopped short in quoting of 11:2: "God hath not cast away His people
which he foreknew." Which
clearly is not as blanket a statement as you interpret. W
hich He foreknew, either applies to 'has not cast away' or to 'His people'. Grammatically, at least, the latter is makes more sense, which would also agree with (Rom 8:29), that God did
foreknow ALL them that would be conformed to the image of His dear Son. (Whether Gentiles for 1st time, or Jew graffed in again)
"God hath not cast away His people
which he foreknew..." Because He is able to
reserve to Himself (v 4) and graft in again
a remnant of natural Israelites (v 5), which Paul clearly speaks of himself, as well as all other of his kinsmen according the flesh (Rom 9:3), who abide not in unbelief...(v 23).
