Well RB I see it a bit different than you do, but the Lord's true ecclesia will get there in one way or another
I believe that Matthew 24 is all about Israel during the coming 70 week decreed for a returned remnant of the same to the land .... and the gathering will be of the believing mortal survivors of the time of Jacob's trouble who will enter and populate the Lord's millennial kingdom upon the earth [Isaiah 11; 27:12-13; Matthew 24:29-31]
Isaiah 11 is about the Millennium who is part of the Day of the Lord beginning upon Jesus second coming.... Isaiah 11:11 have nothing to do with the formation of the State of Israel in 1948 (synagogue of Satan (Rev 3:9)...

Isaiah 11
6
The wolf also shall dwell with the lamb, and the leopard shall lie down with the kid; and the calf and the young lion and the fatling together; and a little child shall lead them.
7 And the cow and the bear shall feed; their young ones shall lie down together:
and the lion shall eat straw like the ox.
8
And the sucking child shall play on the hole of the asp, and the weaned child shall put his hand on the cockatrice' den.
9 They shall not hurt nor destroy in all my holy mountain: for the earth shall be full of the knowledge of the Lord, as the waters cover the sea.
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.
11
And it shall come to pass in that day, that the Lord shall set his hand again the second time to recover the remnant of his people, which shall be left, from Assyria, and from Egypt, and from Pathros, and from Cush, and from Elam, and from Shinar, and from Hamath, and from the islands of the sea.
12 And he shall set up an ensign for the nations, and shall assemble the outcasts of Israel, and gather together the dispersed of Judah from the four corners of the earth
Straightshot said:
Then the Lord will gather the surviving mortals of the period of the Gentile nations and those that are found believing will enter the same [Matthew 25:31-46]
Agreed !
Straightshot said:
But today's true ecclesia of both the dead in Christ and those living [Jew or Gentile] will go before as immortals [Revelation 3:10]
Why do you think that the address to the Church of Philadelphia is limited to Revelation 3 verse 10 only ... ? Why is there verse 12 saying to the same Church of Philadelphia about overcoming:
"Him that overcometh will I make a pillar in the temple of my God,"v12 ... overcoming what if as you believe they will not be there ????
Revelation 3
7 And to the angel of the church in Philadelphia write; These things saith he that is holy, he that is true, he that hath the key of David, he that openeth, and no man shutteth; and shutteth, and no man openeth;
8 I know thy works: behold, I have set before thee an open door, and no man can shut it: for thou hast a little strength, and hast kept my word, and hast not denied my name.
9 Behold, I will make them of the synagogue of Satan, which say they are Jews, and are not, but do lie; behold, I will make them to come and worship before thy feet, and to know that I have loved thee.
10
Because thou hast kept the word of my patience, I also will keep thee from the hour of temptation, which shall come upon all the world, to try them that dwell upon the earth.
11 Behold, I come quickly: hold that fast which thou hast, that no man take thy crown.
12
Him that overcometh will I make a pillar in the temple of my God, and he shall go no more out: and I will write upon him the name of my God, and the name of the city of my God,
which is new Jerusalem, which cometh down out of heaven from my God: and I will write upon him my new name.
13 He that hath an ear, let him hear what the Spirit saith unto the churches.
The explanation for Revelation 3:10
The hour of temptation that we will be keep from (falling ) is related to
.... how even the elect if it were possible, would be deceived (Matthew 24:24) ...
That is why...
12
Him that overcometh will I make a pillar in the temple of my God, and he shall go no more out: and I will write upon him the name of my God, and the name of the city of my God, which is new Jerusalem, which cometh down out of heaven from my God: and I will write upon him my new name.
Explanation
***
The formation of the State of Israel in 1948 is in line with that end time prophecy (Rev 3:9) ... and of course about the prophecies related with the State of Israel during the future Tribulation.
Revelation 3:9
9 Behold,
I will make them of the synagogue of Satan, which say they are Jews, and are not, but do lie; behold,
I will make them to come and worship before thy feet,
and to know that I have loved thee.
