Absolutely I believe God's covenant promise remains with Israel--only now through the New Covenant. The Old Covenant of Mosaic Law expired, and God had fully anticipated it would expire, just as the Law was utterly unable, at its core, of ushering in Eternal Life on its own. Remember that only a single broken law could expel Adam and Eve from Eternal Life. The Law of Moses simply reinforced that fact. Only Christ would provide Eternal Life where the Law failed. So yes, God had every intention of maintaining His relationship with the nation Israel. But it had to come through Christ, and not through the Covenant of Law.
Yes, I went through these questions way back in the mid-70s, when the New International Version, the NT exclusively, first appeared where I was. I had been reading George Eldon Ladd, a NT theologian and specialist in biblical eschatology.
I noted where he began to introduce to me a foreign view of the passage, "the Kingdom comes by force," and then saw the same language in the NIV NT Bible. I searched to see if Ladd had contributed to this reading, and I believe back then his name was listed among the credits. I haven't seen it since then.
The older reading of the text, prior to the NIV, seemed to suggest that wicked Jewish leaders were trying to force their way into controlling the temporal kingdom of God on earth, which is Israel. And this seemed much more natural to me.
Unfortunately for my pov, people have picked up on Ladd's view and on this new language in the NIV, and has become very popular with Christians who adopt a "Faith" attitude. They claim they can do this or that, and so bring in the Kingdom by force.
That seems very unnatural to me, and in fact, unspiritual. How can we "force" God's Kingdom to come? But I don't make divisions with Christians who want to believe this. We all need to be convicted by our own guidance from God.
If you think about it, most all of Europe has at one time or another claimed to be Christian. So when that society changes and goes back to pagan living, it in a sense brings back "7 demons with it." It is a replay of what happened to Israel when they backslid, in the days just before the Babylonian Captivity. Religious people, when they turn away from God and back to their old ways, become awful people!
I don't make dates, but I agree with your assessment of the dire condition of the West today, particularly with COVID. Progressives have become almost militant and dedicated to a one-party system. And its object appears to be to shut down Christian culture as a threat to their "freedoms." Thanks for sharing!
