There will be a resurrection of the saints,for the Bible says we will be caught up in the air to meet Jesus,and so we shall be with the Lord forever,and in Zechariah 14,it says when God comes to fight the world that fought against Israel,that the saints are with Him,which is in Revelation 19,when Jesus comes back the saints who are in heaven come back with Him,in which God said He will step on the Mount of Olives,in which Jesus said when He comes back He will step on the Mount of Olives.
But this resurrection does not happen before the tribulation,for the Bible says that the saints will not be united with Jesus until the antichrist steps in to the Jews temple claiming to be God,and the beast makes war against the saints,and the saints are given in to the little horn's hand for three and one half years,and the last king will destroy the mighty and holy people.
The truth is as long as the world can repent of their sins,they can be saved,and as long as the world can be saved,God will not take home His children.
The world can repent of their sins until they take the mark of the beast.
God will not give up on the world until they give up on Him.When the world takes the mark and makes war against the saints,which the Bible says the last king will cast the truth to the ground and stamp upon it,and the beast blasphemes against God and His tabernacle,then the world wants nothing to do with God,and God can take His children home.
Then the wrath of God will be poured upon the world,and God will come back with His saints and save Israel,and all Gentile governments will not be in operation anymore,but the kingdom will be restored to Israel,which the Bible says all Israel shall be saved,but that is the kingdom on earth,for all Israel is not saved spiritually.
That is true that we will know when the tribulation will start by the 7 years peace treaty,for three and one half years after the signing of the peace treaty,the man of sin will step in the Jews temple and claim to be their God,which then will be persecution against the saints like never has been before.
