Ethnos is a general term. When the BIble uses it in prophecy, an accurate rendering is "people from all nations", not all people from all nations.
Now there can be faithful anointed that are from all nations (Rev.5:9,10; 7:9,15,17),
and there can be wicked persecutors from all nations (Rev.11:9; 17:15).
Obviously, this is not the same group, although both groups, are international, and can be partially described by the word "Ethnos"
I'm sorry about the searchbox. I have changed it a few times when it stops working completely. Yet I find it is limited in getting all the desired search results.
Google has vendored out some of it's services, and the WT has jumped at the chance to get in the door to control some of the software and tools being used by us out here.
They can offer their services for free, and how would Google grasp their true intentions?
Back to the subject.
Yes. "kingdom against kingdom" means sparring dominions under their own "king".
The kings of the earth, are those chosen by Christ to have authority and power against Satan and his seed
(Rev.1:5; 5:10; 3:21; 1John5:4; 1Cor.15:57; Eph.2:6; Luke10:19; Matt.16:19).
If we use the "little" royal power, knowledge, and authority well (Rev.3:8; Luke10:19); we will be granted the full reward of an eternal dominion over all creation (Matt.13:12).
Previously to becoming sealed, is the time of testing. What we do with the "little" spirit and truth we are given (Luke16:10; Matt.25:23; 28:19,20)
will determine the judgment of Christ during our inspection by the Master.
Once sealed, we enter the marriage feast of full provisions, because we have proven our desire to obey in serving God exclusively and fully.
For these, the "tree of life" is again within reach. The hidden manna and morning star is also given them in their hearts.
These rely exclusively on the spirit of the truth, which is sourced in God's Word alone, just as Christ did not speak of his own originality.
It comes to us from the Father, and through the "vine"/root, Christ (see John chapter 15) by means of holy spirit (Rom.11:17) and faithful "pruned"/refined branches (John15:2).
Some branches get "lopped off" completely, for not providing fine fruit (according to the standards just mentioned).
They have left their unity with the "head", Christ, and this divine arrangement of provisions through the arrangement of Christ's body.
These self-centered puffed up "kings" have nothing of value to offer, and will be recognized by such "fruit".
Clearly, those teaching demonic lies are brought into battle with those who defend the truth (Rev.16:13-16; 17:14; 19:11,14; 12:7,8,10,11).
That battle, yes, is mentioned at Matt.24:7,
and this can be read about in more depth, at pearl-sign.blogspot.com, under "warfare".
Since the first century, all anointed are chosen from all nations, or from among physical Gentiles, to become spiritual Jews (Rom.2:28,29; Gal.3:29; Rom.9:6; Matt.3:9; Gal.6:16).
Yet there is also the concept of spiritual Gentiles. These have not received the circumcision of the heart by spirit, and are forbidden to serve in the Temple as anointed priests.
These can also be referred to as the "Nations"/Gentiles.
God makes his home among the PHYSICAL GENTILES/SPIRITUAL JEWS as the abiding place/Temple of His spirit (1Cor.3:16; Eph.2:20,21,22).
Those words which contain the word for "home" are commonly translated, not as Nations/Gentiles, but as "earth" and "world".
This is not the Greek word "Ethnos", but rather
"oikoumenEs" and "katoikountas"
The "earth" and "world" (poor translations of "home"), are the dwelling of God's spirit.
That place can also be referred to as from all nations "Ethnos", as a description of that "home",
but that is not the same Greek word for home/earth/world.
I'm afraid you may have the word "oikou" mixed up with "Ethnos". They are not the same.
The home is made up of people from all nations,
but so is the group of wicked made up of all nations.
So Ethnos is not interchangeable with Oikou (homeland).
(For example, you may describe your home as brick, but this does not mean that all brick homes are yours.
Ethnos is a description that can fit many groups composed of many nations, but only one international group, is God's home.)
But yes...the spiritual "nations" battle [God's Nation/seed (Heb.13:14; 12:22,23; John15:19; 1Pet.2:10; 1:23; John13:35; Rom.8:5,6)
against Satan's seed/Nation (John8:44; Rev.9:11; 2Thess.2:3; James4:4; 1John2:15; 4:20; James3:15)],
("kingdom against kingdom") due to the opposing forces of invited kings, based upon the spirit in their mouth,
whether that be the spirits/teachings of demons (Rev.16:13-16),
of the spirit/teachings of God (Matt.10:20; John20:22). This battling is the very essence of Armageddon.
Now your reference to Matt.20:25 is where this gets interesting...
“25 But Jesus called them to Himself and said, “You know that the rulers of the Gentiles lord it over them, and those who are great exercise authority over them. “
But if you check how the meticulous physician Luke recorded Christ's words, he wrote...
"Jesus said to them, "The kings of the Gentiles lord it over them; and those who exercise authority over them call themselves Benefactors." (Luke22:25)
Was Jesus so concerned here, that his disciples would take public office, or was he pointing to a spiritual arrogance among God's flock,
such as he warned against before (Mark8:15; Matt.5:20). "Herod" and the "Pharisees" exercized a rulership, among God's people.
THIS is what Christ was referring to.
Now lets peel it back further....
These exercising unfounded authority and oppressive restraint, "call themselves benefactors"!
This is a very important detail,
because it is a vital portion of prophecy.
This is the very same stature and position held by the false prophet/two-horned wild beast, who actually IS, OVER the GENTILE wild beast. (Rev.13:1,11)
Who does this one who is "lording" over the Gentiles, "benefit"??
In speaking of this two-horned Beast...
"12 He exerts all the power and right of control of the former beast in his presence, and causes the earth and those who dwell upon it to exalt and deify the first beast (Gentile), whose deadly wound was healed, and to worship him." (Rev.13:12)
Now look at an interlinear of verses 14 and 15:
There it says that lying signs are performed by the "Two-horned" Beast, "on behalf of" ("enopion") the first Gentile Beast!
Confirmation comes in a second scripture...
at Rev.19:20. There this same benefactor of the Gentile Wild Beast is then called, "the False Prophet".
He performs the very same lying signs as the dragon-tongued two-horned Beast. They are the same identity...
and they are both a "benefactor" to the Gentiles.
So, we see clearly, that a false prophet who appears to be a lamb of Christ (but speaks like a dragon -Rev.13:11)
is a benefactor to the Gentile Wild Beast.
Surely Jesus knew what was to come, and he did not want his anointed disciples to have any part in this (1Cor.6:15) (2Cor.11:2-4) (Rev.14:4).
Yet we know that not all successfully stay unstained by this arrangement (Rev.2:20-22; 17:1-2).
The "ten kings" are deceived by this false prophet, and give their crowns to the Gentile Beast (Rev.17:12,17; 13:1),
losing their kingdom inheritance by preferring to rule with the deified Gentile Beast.
Their alliance with the Gentile WIld Beast will not only bring them into battle with the Lamb and his faithful (Rev.17:14);
their alliance will also take down the last Harlot/two-horned Beast/False Prophet,
who enabled it to rule with it's illusion/Image of divinity (Rev.17:1, 16-17).
....and yes, this is the GB who has enabled the Gentile Organization to appear to be "spirit-directed" ("pneuma"= breath/spirit) (Rev.13:15; John20:22),
in contrast to/counterfeit imitation of, the True Temple and Body of Christ.
How this ties in with your question about the "Nations", I am not clear.
I am hoping that somehow, by laying these details out for you,
I have covered what you were asking about. If not, please just clarify, and I'll try again.
Our Father's love, protection, and grace keep with you Peely,
