I do not believe the literal, national Israel will ever be restored, but individual Jews are part of the spiritual Kingdom of Christ according to His grace and regeneration of the Holy Spirit.
It is quite irrelevant what you believe, as belief, and the truth, are independent. You made the above up:
Isaiah 46:13 KJV
I bring near my righteousness; it shall not be far off, and my salvation shall not tarry: and
I will place salvation in Zion for Israel my glory.
Zechariah 8:23 KJV
Thus saith the Lord of hosts; In those days it shall come to pass, that ten men shall take hold out of all languages of the nations,
even shall take hold of the skirt of him that is a Jew, saying, We will go with you: for we have heard that God is with you.
Matthew 19:28 KJV
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.
Luke 22:30 KJV
that ye may eat and drink at my table in my kingdom, and
sit on thrones judging the twelve tribes of Israel.
Isaiah 2:3 KJV
And many people shall go and say, Come ye, and let us go up to the mountain of the Lord, to the house of the God of Jacob; and he will teach us of his ways, and
we will walk in his paths:
for out of Zion shall go forth the law, and the word of the Lord from Jerusalem.Micah 4:2 KJV
And
many nations shall come, and say, Come, and let us go up to the mountain of the Lord, and to the house of the God of Jacob; and he will teach us of his ways, and
we will walk in his paths:
for the law shall go forth of Zion, and the word of the Lord from Jerusalem.
Zechariah 8:3 KJV
Thus saith the Lord;
I am returned unto Zion, and will dwell in the midst of Jerusalem: and Jerusalem shall be called a city of truth; and the mountain of the Lord of hosts the holy mountain.
