First of all there is no the Great tribulation, it is Great Tribulation.
Next, all the body of Christ will not be out of here, there is one portion of the Church that receives that reward, and that is one part of the bride of Christ. They and the other part of the bride are present in heaven with Jesus when He receives His own throne in Rev 4:2 prior to the first three and one-half years of Great tribulation is called the Temptation that is to come upon all the world in Rev 3:10. How did those alive when Jesus came in the air escape? Keeping the word of Jesus’ patience, or patiently keeping the word of God.
There is to be a second three and one-half years of tribulation none of the Church will be present on earth for, and that is described in Mat 24:21 For then shall be great tribulation, such as was not since the beginning of the world to this time, no, nor ever shall be. Why is the Church missing this? They are caught up prior to it; call it rapture or what you will as we see them in Rev 7:13-14 & Rev 14:1.
From my understanding there is to be one Great White Throne judgment, and that is to include all whose names are not written in the book of life according to Rev 2:12-13.
This sounds much like Paul in 2 Co 12:2. I knew a man in Christ above fourteen years ago, (whether in the body, I cannot tell; or whether out of the body, I cannot tell: God knoweth;) such an one caught up to the third heaven. I do see where John is invited to come up hither in Rev 4:1, and that was to God’s throne in the third heaven.
The problem is that many put the emphases on the word "The" and the letter "G' as in The Great tribulation, or as you post Great tribulation. Matthew 24:21 For then shall be great tribulation, such as was not since the beginning of the world to this time, no, nor ever shall be........... Not "The" or "G", just great tribulation.
There are not two parts of the Bride of Christ as everyone who has ever walked in faith from Genesis to the timing of the Christ return are the whole Bride of Christ and Jesus has always sat on the right hand of God from the day He ascended up to heaven, Mark 16:19. Rev 4:2 what John was seeing in his vision while he was caught up in the Spirit and not literally in heaven was a vision of the throne of God, Isaiah 6:1; Rev 1:10.
The hour of temptation spoken of in Rev 3:10 are past, present and future temptations. All of us being the Church of Philadelphia that is Gods faithful body in Christ have been sealed by the Holy Spirit, Ephesians 4:30. We are to stand strong in the Holy place that is Christ Jesus in whom is our faith as we trust Him in all things, Matthew 24:15 and not to fear that of Gods wrath being poured out on all the nations as they refuse to repent for we are not to fear what man can do to us, but fear that of what God will do to us of we lose that faith that is Christ Jesus as many will denounce Him in order to try and save their own lives especially when they receive the mark of the beast, Matthew 10:28; 16:25, Rev 13:16-18.
Matthew 24:21 says that there will be great tribulation and such a greater tribulation that man has ever seen before as the world has always had tribulations and this last tribulation against those who refuse to repent is more intense then any other during the seven trumpets and seven vial judgments that the world has ever seen before. It's not a separate tribulation, but only that of the greatest one ever seen, Deut 4:30; John 16:33; Romans 8:35.
Rev 7:13, 14 are those souls who are reserved in heaven under the altar waiting for their blood to be avenged as they came out of great tribulation and are to wait awhile until their fellow servants who will also die a martyr's death at the end of days as then all things of the prophecies of Gods word will be fulfilled and then we will be with the Lord forever in the New Jerusalem when it is ushered down.
Rev 14:1 The Lamb represents Jesus who stands on the symbolic mount Sion in the heavenly Jerusalem meaning where God, Jesus and the holy angels dwell which is called the heaven of heavens, Hebrews 12:22-24; Deuteronomy 10:14; 1 Kings 8:27; Psalms 115:16. The hundred and forty four thousand that John sees standing with Jesus is not a literal numbering, but symbolic of those of Gods established covenant with faithful Abraham up through a thousand generations, Deuteronomy 7:9; Galatians 3:6, 7; 3:28, 29. It is those of great faith to the Jew first and then the Gentile who have gone on before us as together with them all who are alive or have died before the Lords return makes up the complete body of Christ, Ephesians 5:25-27.
To understand the mark of the beast one has to understand who the beast is that rises from the earth in Rev 13:11-18 and who gives power to this beast. Many will bow down and take this mark as being the actions of their hands and thoughts of their mind as they love their own life and will lose it, but those who lose their lives for the sake of Christ will find life eternal with the Father, Matthew 16:25. Many Christians will lose their faith in fear of losing their own life and will denounce Christ when faced with being persecuted, even to death for refusing this mark of the beast as it promises a false peace and safety.
Everything John was given by Jesus through the angel who gave him these visions while he was only caught up in the Spirit and never taken up physically to the third heaven are warnings not only to the Church being the true body of Christ like the Church of Philadelphia, but also to all who refuse to repent. Those who are in Christ and still alive at the time of the seven trumpets sounding God will give a greater anointing to those He appoints to preach the Gospels as many will finally open their ears to hear and repent and turn back to God, just as the thief on the cross in whom ask Jesus to remember him and Jesus said you will be with me in Paradise this day.
