The church will be absent from the earth when the mark of the beast goes into effect (Revelation 13). You will not find the words "church" or "churches" from Revelation 4 to Revelation 18. Thus the issue is moot. The Tribulation Saints will refuse to take the mark, and will be beheaded (Rev 20).
Paul said let no man deceive you by any means for the gathering of the saints shall not happen until there is a falling away first.
Which the falling away is the condition of the world in response to the Gospel which the nations governments came together for a one world government and will not allow the preaching of the Gospel, and a personal God, favoring their religious system that believes people are evolving to be spiritual, and a god, and there is no personal God.
And the man of sin claims to be God which he does in the middle of a 7 years period that God is allowing the world to have their way for 7 years.
The resurrection shall not happen until that time so it will be before the middle of the 7 years period.
And then the beast makes war against the saints and prevails against them, and they are given in to his hands for three and one half years, and when he shall have accomplished to scatter the power of the saints then all things are finished.
Which then comes the end when the Son shall deliver the kingdom up to the Father, and then He shall put down all authority, power, and rule.
So the saints shall go through the 7 years period.
Also the Son puts the world down when the resurrection happens so if the resurrection happens before the 7 years period then why does God allow them to continue for 7 years.
It is the end when the Son delivers up the kingdom to the Father so why would God allow them to continue for 7 years if it is the end.
So if the resurrection is before the 7 years then God would not allow them to continue for 7 years because it is the end.
The resurrection happens after the 7 years period for then it is the end.
Also there is no tribulation saints because Jesus said if they miss the resurrection He shut the door so they cannot enter and will have their portion with the hypocrites.
Also when the resurrection happens the world has no chance to be saved for if they missed it for they denied the truth.
The Bible says the Gospel will be preached in to all the world as a witness to all nations before the resurrection so all people will know of it so if they missed the resurrection they missed out.
Also God is allowing the world 7 years to have their way and go against the truth, and cause all people that do not love Him to follow the beast kingdom, and then He will end sin on Earth.
So if God is allowing the world to have their way for 7 years then the saints will remain on Earth to represent the truth for if the saints were not on Earth then how does the world go against the truth for 7 years.
Also for the first three and one half years the world has salvation available to them like now so the saints will remain on Earth to represent the truth so there is no resurrection before the 7 years period.
Paul said let no person deceive you for the saints will not be gathered unto Christ until the man of sin claims to be God which happens in the middle of the 7 years period.
Also there is only 2 resurrections 1 of the saints, and 1 of the dead, not 2 resurrections of the saints, 1 before the 7 years period, and 1 later on, for there is only 1 resurrection of the saints.
Also there is not a resurrection of the saints, and then Jesus comes back to be united with tribulation saints that do not get caught up.
Because the Bible says that at the battle of Armageddon when Jesus fights the world and defeats them that the LORD my God shall come, and all the saints with thee.
So when Jesus comes back all the saints come back with Him so there is no saints on Earth so there is no tribulation saints.
So there is not a second resurrection of tribulation saints for there is only 1 resurrection of the saints, and there is no tribulation saints on Earth when Jesus comes back because all the saints are with Him.
1Ti 4:1 Now the Spirit speaketh expressly, that in the latter times some shall depart from the faith, giving heed to seducing spirits, and doctrines of devils;
1Ti 4:2 Speaking lies in hypocrisy; having their conscience seared with a hot iron;
1Ti 4:3 Forbidding to marry, and commanding to abstain from meats, which God hath created to be received with thanksgiving of them which believe and know the truth.
1Ti 4:4 For every creature of God is good, and nothing to be refused, if it be received with thanksgiving:
1Ti 4:5 For it is sanctified by the word of God and prayer.
2Ti 4:2 Preach the word; be instant in season, out of season; reprove, rebuke, exhort with all longsuffering and doctrine.
2Ti 4:3 For the time will come when they will not endure sound doctrine; but after their own lusts shall they heap to themselves teachers, having itching ears;
2Ti 4:4 And they shall turn away their ears from the truth, and shall be turned unto fables.
Some shall depart from the faith and follow the new age movement interpretation of the Bible that is of the antichrist.
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 it will overthrow the faith of some people that had faith and they will follow the new age movement interpretation of the Bible.
And then the people that preached a resurrection happening before the 7 years period will be responsible for those people losing faith because they thought they missed the resurrection, and either thought that they missed out on salvation, or the Bible was not true how it was preached for many years.
Also for people that think that God would not allow the saints to go through tribulation during a 7 years period the wrath of God is not in the 7 years period.
The first three and one half years salvation is available to the world so the wrath of God would not be there.
When the beast claims to be God then he has three and one half years to continue, and has power over all nations, kindreds, and tongues, so the wrath of God would not be there.
God is giving the world 7 years to have their way so the wrath of God not be there for if it was then how did God give them their way.
