There is no pre-7 years resurrection of the saints.
There is only 2 resurrections, one of the saints before the millennial reign of Christ, and one after the millennial reign of Christ.
There is no tribulation Gentile saints if it is pre-7 years resurrection for Jesus said when the resurrection happens the hypocrites will not be caught up, and when He has shut the door no person can enter after that.
The Jews will be all back on their land, and none in the Gentile nations anymore by way of the 7 years peace treaty, and the nation of Israel is protected from physical attack for the 7 years period, and the 2 witnesses only started witnessing to Israel to turn them to the truth at the middle of the 7 years period, but the beast makes war against the saints worldwide at the middle of the 7 years period, so that means he is going against Gentile saints, but if it is a pre-7 years period there would be no Gentile saints on earth, so if there is Gentile saints on earth at the middle of the 7 years period the resurrection has not happened.
Paul said when the nations come together and say Peace and safety the saints will not be deceived by that for they will know it is not of God as they try to have peace on earth, and Jesus said He will deliver the saints from the temptation that shall come upon the whole world to try them that dwell on earth, which is a deciding factor for the world, be with God, or follow the world, as reality of salvation, and peace on earth, which the nations coming together is the start of the 7 years period and the saints are on earth, so the resurrection has not happened when the 7 years period begins.
The Bible says Israel is blinded in part until the fulness of the Gentiles be come in, when salvation is no longer available to the Gentiles, and so all Israel shall be saved, but the world has repentance, and salvation offered to them until they take the mark of the beast which happens at the middle of the 7 years period, so repentance, and salvation, is still available to the Gentiles for the first three and one half years, so that means the resurrection has not happened yet, for there is no Gentile that can be saved if it is a pre-7 years resurrection.
The beast makes war against the saints, and prevails against them, and they are given in to his hands for the last three and one half years, and when he shall have accomplished to scatter the power of the holy people then all things are finished, which then comes the end when the Son shall have delivered up the kingdom to the Father, which this is persecution worldwide, for it is the greatest persecution ever in the history of mankind, so Gentile saints have to be persecuted for all the Jews are on their land, and none of them in the nations anymore.
If it is a pre-7 years resurrection then there can be no Gentile saint after that point, but there is Gentiles that can still be saved during the first three and one half years, and the beast makes war against Gentile saints during the last three and one half years, testifying that the resurrection cannot happen before the 7 years period begins.
That is why Paul said the gathering of the saints unto Christ cannot happen until there is a falling away first, which is the world in response to the Gospel that they stop the preaching of it worldwide as international law, and at the end of the first three and one half years the transgressors have come to the full, and the man of sin claims to be God by harnessing the power of nature, the God of forces, then the saints can be gathered unto Christ, but then the saints are given in to his hands for the last three and one half years.
Repentance, and salvation, is still available to the world during the first three and one half years, so the saints will remain on earth to represent the truth, which when the beast claims to be God he blasphemes God, and His tabernacle, so the saints are on earth, for if they were not he would not have to go against the truth if the truth was gone from the earth.
There is no pre-7 years resurrection of the saints, but will not happen until the man of sin, New Age Christ, claims to be God, and makes war against the saints, which is both Jew and Gentile saints for it is worldwide, but Israel is protected from physical attack for the 7 years period.
And for people that would say that God would not allow the saints to go through the tribulation that reason is not valid, for that would mean God would of not allowed the saints to be persecuted at any time in Church history.
And the tribulation is not for the world, but for the saints, which is why Jesus said there will be persecution against the truth like never before in the history of mankind, and that is because it is on a worldwide level.
2Ti 2:16 But shun profane and vain babblings: for they will increase unto more ungodliness.
2Ti 2:17 And their word will eat as doth a canker: of whom is Hymenaeus and Philetus;
2Ti 2:18 Who concerning the truth have erred, saying that the resurrection is past already; and overthrow the faith of some.
When the resurrection does not happen before the 7 years period begins it will overthrow the faith of many, and they will follow the world saying this must be reality, and their interpretation of the Bible was wrong as they embrace the new age movement, and evolution.
