The language used in Rev. 2 is really no different than the language Paul uses to describe "Israel".
"But it is not that the word of God has taken no effect. For they are not all Israel who are of Israel, nor are they all children because they are the seed of Abraham; but, 'In Isaac your seed shall be called.'" (Rom. 9:6,7)
Not evenyone who claims to be a Jews by virtue of the "brthright" from Abraham really is a Jew because they do not share in the faith of Abraham. If they did share in the faith of Abraham they would fall down before Jesus the Messiah and true King of Israel, the one seated on David's throne in heaven.
"For he is not a Jew who is one outwardly, nor is circumcision that which is outward in the flesh; but he is a Jew who is one inwardly; and circumcision is that of the heart, in the Spirit, not in the letter; whose praise is not from men but from God." (Rom. 2:28,29)
There are people who say they are Jews, and they are...
Real Jews follow Jesus.
True Israel will (eventually) come to faith in Christ.
A couple of problems here...David's throne is not in heaven and Jesus is not yet crowned the King of Kings...
Joh 18:36 Jesus answered, My kingdom is not of this world: if my kingdom were of this world, then would my servants fight, that I should not be delivered to the Jews: but now is my kingdom not from hence.
His kingdom is not from here NOW...But it will be from here...
David's throne is a physical throne in a physical kingdom with a physical temple...
Those within the time frame of the prophecy of Mat., will have made it to heaven and sit with Jesus to Judge Israel...And this would be the Bride of Christ...
Mat 19:28 And Jesus said unto them, Verily I say unto you, That ye which have followed me, in the regeneration when the Son of man shall sit in the throne of his glory, ye also shall sit upon twelve thrones, judging the twelve tribes of Israel.
Rev 20:4 And I saw thrones, and they sat upon them, and judgment was given unto them: and I saw the souls of them that were beheaded for the witness of Jesus, and for the word of God, and which had not worshiped the beast, neither his image, neither had received his mark upon their foreheads, or in their hands; and they lived and reigned with Christ a thousand years.
I understand your church 'spiritualized most of Revelation (whatever that means) and do not accept it as reality...But you have to throw away an awful lot of bible if you're going to throw away Revelation since a large portion of the bible refers to this time period...
Mat 19:29 And every one that hath forsaken houses, or brethren, or sisters, or father, or mother, or wife, or children, or lands, for my name's sake, shall receive a hundredfold, and shall inherit everlasting life.
And notice, these 'real Jews' will have some pretty tough requirements to get eternal life...And you also notice there is no requirement of baptism...No requirement of the Eucharist...It's pretty clear that Mat. 19:26 does not refer to any Christians...
And of course not...They are already sitting on the physical thrones as the Bride of Christ in the city of Jerusalem judging and reigning with Christ for a thousand years...And then, the White Throne Judgment...
