At this hour it seems appropriate to revisit this Discussion.
Here's a rhetorical question:
If the physical nation of Israel has been permanently rejected & abandoned by Jehovah, if it no longer has any place in the outworking of His plan, and for all intents & purposes has been eternally discarded, why is Jesus Christ known now, and forevermore, as "The Lion of the Tribe of Judah" (Rev 5:5)?
Paul wrote:
"concerning [Jehovah's] Son, who came to be from the offspring of David according to the flesh, but who with power was declared God’s Son according to the spirit of holiness by means of resurrection from the dead yes, Jesus Christ our Lord." Rom 1:3-4
And
"To [the Israelites] the forefathers belong, and from them the Christ descended according to the flesh." Rom 9:5
Jesus is God's Son - but Jehovah isn't Jewish. Jesus' Jewish ancestry is "according to the flesh" - which means the title "The Lion of the Tribe of Judah" refers, and inseparably links Jesus forever, to PHYSICAL Israel. It confirms that the physical Jews are (still) Jesus' "brothers".
Considering Jesus bases his judgement of Matt 25 on the way a person treats "the least of" His brothers, we all should be very careful of how we view & treat the physical Jews.
(Of course this also applies to Christ's Christian brothers, too; indeed we must aim to treat ALL people well if we want to cover all bases. But it's especially relevant in this hour as we're witnessing a particularly violent & threatening antisemitism spreading rapidly throughout the world.)
Some here have argued that Satan might be targeting the Jews as part of an old, irrelevant "grudge". I would argue that Satan is targeting the Jews precisely because they are - despite their faults - still God's people. (Christians are also God's people - so we can be assured tribulation & persecution are headed our way soon too.)
"I ask, then, God did not reject his people, did he? By no means! ... God did not reject his people, whom he first recognized." Rom 11:1-2
I think you should define what Jew means in your question, because you are using the word to define the past Israelite nation, and equating it with the modern day group who call themselves Jew, and they are not the same. You also equate Gods people with Christians today and while that is obviously true, the world views the word Christian to believe in a trinitarian God.
Thus the majority of the world who call themselves Christian, are completely different from an actual Christian who believes and follows the one true God Jehovah. The word Christian has been plagiarized from true Christianity and given to a group of people who neither know Jehovah or his son. The term Jew today is no different, as respects being taken from a group of people who did represent Jehovah prior to Jesus Christ, and is now given to a people who also do not know Jehovah or Jesus Christ.
With that in mind then, I think we should allow the scriptures to define what those words mean, as that should be the only standard we compare anything to.
“. . .For he is not a Jew who is one on the outside, nor is circumcision that which is on the outside upon the flesh.
29 But he is a Jew who is one on the inside, and [his] circumcision is that of the heart by spirit, and not by a written code. The praise of that one comes, not from men, but from God.” (Ro 2:28-29)
“. . .yes, God’s righteousness through the faith in Jesus Christ, for all those having faith.
For there is no distinction...between Jew and Greek” (Ro 3:22, 10:12)
“. . .
There is neither Jew nor Greek, there is neither slave nor freeman, there is neither male nor female; for YOU are all one [person] in union with Christ Jesus.” (Ga 3:28)
Judaism from a religious standpoint was destroyed when Jesus Christ fulfilled the law. It was done, and no longer valid in Jehovahs eyes, which is the only view that matters. But your question also asks whether we shouldn't be careful how we view and treat the physical Jews. The bible clearly states that there is no distinction anymore between the Jew and any other foreign nations. Your question elevates a people above others when in fact we should be careful how we treat everybody, not just those you call 'physical' jews. Your question highlights the problem in a nutshell regarding what is wrong with how the people who call themselves jews view themselves. Anytime somebody thinks they are better than somebody else there will be problems. Not only with entitlement, but also how they view those who are not of the same ideology with disdain.
You quote Romans 11:1-2 talking of the Israelite nation being first recognized, however the scriptures are also quite clear regarding this.
“. . .He does away with what is first that he may establish what is second.” (Heb 10:9)
Thus being first recognized by God carries no weight anymore as to how God views the Israelite nation.
I could go on, but I feel like your questions are loaded with an agenda to incite something rather than truly understand.
