The bible is meaningless as a guide to the future
of Israel, Spain, New Zealand and the USA.
To Love one another is our final command and the bible can be used,
to prove that to fellow believers.
These are some of the great Christian Nations.
I would say they are the inheritors of the birthright passed down from Abraham through Ephraim [house of Israel] which we see here as Jacob prophesies over his grandsons:
18 And Joseph said unto his father, Not so, my father: for this is the firstborn; put thy right hand upon his head.
19 And his father refused, and said, I know it, my son, I know it: he also shall become a people, and he also shall be great: but truly his younger brother shall be greater than he, and his seed shall become a multitude of nations.
The general beliefs that you outline here seem a lot like the beliefs of the Christian Identity movement. They believe that whites of European descent can be traced back to the "Lost Tribes of Israel." They say that Jesus Christ will return to the Earth following a period of "tribulation." They view the apocalypse as a racial battle.
The book of Daniel. and Jesus himself, tells us that the invasion of Jerusalem by foreign armies will kick off the last three and a half years before the return of Christ.
It is during this time that "the enlightened ones" of the church [the Maskilim] will minister to and evangelize the Jews [house of Judah] who are to be brought into the New Covenant before the Age ends [and after the fulness of the Gentiles has been achieved]--so that God can hold both sticks in one hand, another OT prophesy.
So there is still a lot going on with the church in the end times.
The church, in Rev. 12, is represented by the woman clothed with the sun, who is seen in heaven. Paul said believers "sit together in heavenly places in Christ Jesus" which explains why she is in heaven.
But God, who is rich in mercy, for his great love wherewith he loved us,
Even when we were dead in sins, hath quickened us together with Christ, (by grace ye are saved;)
And hath raised us up together, and made us sit together in heavenly places in Christ Jesus:
That in the ages to come he might shew the exceeding riches of his grace in his kindness toward us through Christ Jesus.
The believer is in heaven, as Christ's Spirit is given to them; they are called temples of God.
1 Corinthians 3:16
Know ye not that ye are the temple of God, and that the Spirit of God dwelleth in you?
See also 1 Cor. 6:19. Those who do not have the Spirit are not of Christ. This is what makes one a "Christian." Not race. Not whether one is white, of Caucasian descent, lives in the USA, or New Zealand, or Spain, or the UK, or Germany, or Russia.
But ye are not in the flesh, but in the Spirit, if so be that the Spirit of God dwell in you. Now if any man have not the Spirit of Christ, he is none of his.
In Rev. 12:6, the woman flees to the wilderness.
And the woman fled into the wilderness, where she hath a place prepared of God, that they should feed her there a thousand two hundred and threescore days.
The 1,260 days are not literal days or years, but symbolic, and represent the whole of the remaining time of the church since the Apocalypse was written. In the wilderness there is a place for her that has been prepared by God. In John 14:2, Jesus said, "I go and prepare a place for you." I suggest the "place" of the woman, and the "place" Jesus is preparing for each of us, are the same.
In the wilderness the woman is nourished. Her nourishment is spiritual, and this refers to teachings from the word of God, corresponding to the manna that the Israelites received in the wilderness. Jesus said, "I am the living bread which came down from heaven." [John 6:41, 51]
The wilderness is church's spiritual environment, not a literal wilderness. The meaning of the wilderness of Rev. 12:6 becomes clear, when the significance of the great city in Rev. 11:8 is understood. The concept of the wilderness in Rev. 12:6, 14 contrasts with the great city called Sodom and Egypt, which were both places from which the people of God escaped. Lot and his daughters came out of Sodom, into a wilderness. And the people of Israel came out of Egypt, into a wilderness. The saints are separate from the worldly system in a spiritual sense. The woman fleeing to the wilderness does not mean that the church goes to a literal desert, but the meaning is spiritual.
Paul said the saints have been delivered from the power of darkness
, and are translated
into Christ's kingdom. No change in location is involved.
Giving thanks unto the Father, which hath made us meet to be partakers of the inheritance of the saints in light:
Who hath delivered us from the power of darkness, and hath translated us into the kingdom of his dear Son:
In whom we have redemption through his blood, even the forgiveness of sins:
Peter said the saints have escaped the corruption that is in the world. [2 Pet. 1:4] James said, "Pure religion and undefiled before God and the Father is this, To visit the fatherless and widows in their affliction, and to keep himself unspotted from the world." [Ja. 1:27]
The wilderness in Rev. 12:6 represents the spiritual place where believers come when they depart from the great city, mystical Babylon, and enter into the light of the gospel and Christ's kingdom. When Jesus prayed for his church he said,
I have given them thy word; and the world hath hated them, because they are not of the world
, even as I am not of the world.
I pray not that thou shouldest take them out of the world, but that thou shouldest keep them from the evil.They are not of the world
, even as I am not of the world.
In Rev. 12:13, after the war in heaven, where Satan is cast to the earth, he persecutes the woman.
The nations you refer to as "great Christian Nations" are not the "wilderness" where those who are truly Christians flee. How can great nations flee to the wilderness? Neither is the "wilderness" the USA, or other places that were colonized by Western European countries. It is a spiritual state of separation from the world
, which John identifies with Babylon, and Egypt, and Sodom.
And I heard another voice from heaven, saying, Come out of her, my people, that ye be not partakers of her sins, and that ye receive not of her plagues.
1 John 2:15
Love not the world, neither the things that are in the world. If any man love the world, the love of the Father is not in him.
Ye adulterers and adulteresses, know ye not that the friendship of the world is enmity with God? whosoever therefore will be a friend of the world is the enemy of God.
