I'm with Duran in this instance. All believers on earth at the time will have to go through the GT:
1) Fleshly Israel has been replaced by the Israel of God (Gal. 6:15, 16).
2) God’s people are destined to escape His wrath, but not the persecution heaped upon them by the beasts and their followers.
3) Those caught up in the air will have no advantage over those involved in the first resurrection. Although the time frame for their ascent will differ, they will have the same reward. First group will be part of the first resurrection, after the seventh trumpet blast (Rev. 11:15, 18). The two witnesses, part of the first group, will be publically resurrected after the pouring out of the fifth plague (Rev. 9:11; 11:3, 11, 12; 16:10, 11). Second group will be taken up after the Tribulation (Matt. 24:29-31). In the same way they will be caught up to meet the Lord in the air (1 Thes. 4:15-17 CSBO). The natural sequence of Matt. 24 also places the rapture after the tribulation (Matt. 24:30, 40, 41).
4) Luke exempts no one alive on earth from the Tribulation. To escape it, you had to be part of it (Luke 21:34-36). Paul reasons: “Moreover, if anyone contends even in the games, he is not crowned unless he has contended according to the rules” (2 Tim. 2:5; cf. 1 Cor. 9:24, 25).
5) Relief for Christians will only come after the Tribulation. This Paul confirms: “This takes into account that it is righteous on God’s part to repay tribulation to those who make tribulation for YOU, but, to YOU who suffer tribulation, relief along with us at the revelation of the Lord Jesus from heaven with his powerful angels” (2 Thes. 1:6, 7).
6) Only the Philadelphian Christians are allowed to
escape “the
hour of test.”
This does not refer to the Great Tribulation, but a unique test they had to
endure (Rev. 3:10; cf. Matt. 24:21).
