2 Thessalonians 2 says that the saints cannot be gathered unto Christ until the antichrist appears claiming to be God,which happens halfway through the tribulation,so the saints will be on earth at least halfway through the tribulation.
1.The Bible says the beast makes war against the saints.
2.The Bible says that the saints shall be given in to the antichrist's hands for three and one half years.
3.The Bible says the antichrist shall destroy the mighty and holy people.
4.The Bible says the antichrist blasphemes against God and His tabernacle and casts the truth to the ground and stamps upon it.
If there are no saints on earth then there is no truth for the antichrist to go against,for if the saints are not on earth the antichrist would not have to convince them to not go with the Christian religion but it is all about man and his technology can save him.
If the saints are not on earth the antichrist would not have to speak out against God and the truth for there is no truth there to speak out against.
The truth is God is love and God will not give up on the world until the world gives up on Him.
As long as the world can repent of their sins God will not take His children home.When the world takes the mark of the beast they cannot repent of their sins and God can take His children home for there is no chance for anybody of the world to be saved.
The world can still be saved during the first half of the tribulation period so God will not take His children home during the first half.Also God wants His children on earth representing the truth so the antichrist can go against the truth,and the witness to the world will be there,so if they reject that witness and follow the antichrist,God can then put them down for they rejected the truth.
They cannot reject the truth if the saints are not on earth when the antichrist claims to be God for the truth would not be on earth.
The antichrist does not claim to be God at the beginning of the tribulation period for the world to reject the truth,but claims to be God halfway through the tribulation period,so the saints will not leave before the tribulation period but be in the tribulation.
God is allowing all people who do not love Him to follow the antichrist and reject the truth,so God can put them down,so the saints have to be on earth when the antichrist claims to be God,for the world to reject the truth,which entails taking the mark of the beast and making war against the saints to qualify that they rejected the truth.
Some people say God will not allow the saints to go through the tribulation because we are saved from the wrath of God,but the wrath of God does not happen during the tribulation,because God is giving the world 7 years to have their way and reject the truth.
Some people say God would not allow the saints to go through the tribulation because He loves them,but what about the saints in the past,that were martyred,hanged on crosses,beheaded,and generally persecuted.They were not saved from persecution,and persecution is persecution.It will be no different in the tribulation than any other time in history,only on a bigger scale,but the physical pain will be no different.
Why do you think it is called the tribulation period,because it is tribulation of the saints,not tribulation of the world,which the world's tribulation will come after the 7 years when they face the wrath of God.
The world will not have tribulation during the 7 years,because they will be whooping and a hollering thinking they will prosper and it is all about man and they have a solution to the world's problems,although many will be hurt because of the wars of people they have to battle who oppose them like Muslims who will not play their one world government and religious system and will not accept the antichrist.
Who is going to give tribulation to the world,for the world will not oppose itself that goes along with the one world government and one world religious system,but it is the world giving the saints tribulation and persecution.
The saints will be in the tribulation period,and the world can still be saved for the first half of the tribulation period,so the saints have to be on earth during the first half,and God is allowing the world 7 years to reject the truth,so the saints have to be on earth when the antichrist claims to be God and goes against the truth halfway through the tribulation period.
