We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
When Christ rode into Jerusalem down from the Mount of Olives on a colt (or small horse, or donkey - whatever) on Palm Sunday, he was greeted with Hosannas by excited crowds who believed him to be the Messiah.
His teachings and his miracles had become famous. People threw their cloaks on the road and, presumably, palm leaves, for his horse to walk on.
Much of their enthusiasm was unwarranted, however: the Jews were hoping for a political messiah (using the word "king"), more than they were hoping for the messiah who came to tell them that much of what they believed about being in relationship with God was wrong - and claiming that he had the authority to say so.
"Salvation," for the crowds, meant salvation from the Romans, and "the kingdom of God," in the Hebrew Bible, referred to the literal restoration of a nation of Israel under God, as had been promised to David. There was no concept at the time, I believe, of the now-Christian idea of salvation or the Christian idea of "the kingdom of God." Furthermore, Jesus had no interest I am aware of in politics or governance and had no beef with the Romans.
A radical for sure, in his apparent renunciation of the ordinary world.
My own view is that it refers to God's domain, ie the universe of those souls who seek relationship with God - not any literal kingdom but a "spiritual" (I hate that word), unworldly kingdom. Maybe "transcendent" is a better word.
I suspect that the Jews who welcomed Jesus to Jerusalem were deeply disappointed to discover that Jesus' mission was not worldly, but other-worldly: only a few handfuls of people remained to constitute what the scholars term the "Christ cult" after the crucifixion. It took Paul's inspired work to rebuild on the foundation.
(That's just my amateur take on it all. I am no expert.)
I, too, loathe the world 'spiritual', as it has been robbed of it's meaning by the twits of the new age, who believe that you can make up your own 'cafeteria religion', picking and choosing only the parts you like of any and all of the world's faiths.
There was no concept at the time, I believe, of the now-Christian idea of salvation or the Christian idea of "the kingdom of God."

Because Judaism has no concept of original sin, or a fallen world, or humans to weak to be worthy of G-d's presence by their own choices and actions. So we don't need this kind of "salvation".
The promise of messianic salvation is explicitly national and political - David's descendants are kings, not prophets or priests.
From the Jewish perspective, the notions of a messiah focused on an otherworldly mission - and of an otherworldly "kingdom of God" - are after-the-fact attempts to explain away Jesus' failure to fulfill prophecy, and/or later interpolations by the gentile church.
The Jewish people's goal remains "to establish the world in the Kingdom of God" - this world.
Through observance of the commandments - and through a political, national entity whose observance and faithfulness to the covenant is a light to the nations.
