...Who cares abt the GT...
Jesus cares that we know everything that must come before he comes:
"Take ye heed: behold, I have foretold you all things" (Mark 13:23);
"The Revelation of Jesus Christ, which God gave unto him, to shew unto his servants things which must shortly come to pass; and he sent and signified it by his angel unto his servant John: Who bare record of the word of God, and of the testimony of Jesus Christ, and of all things that he saw. Blessed is he that readeth, and they that hear the words of this prophecy, and keep those things which are written therein: for the time is at hand" (Revelation 1:1-3).
...Christians will be raptured out of the earth by then...
Note that no scripture promises us a rapture before the tribulation. Jesus says he will come to gather us together "immediately after the tribulation" (Matthew 24:29-31), and Paul says Jesus' coming to gather us together must "destroy" the Antichrist (2 Thessalonians 2:1-8). We Christians must go through the coming tribulation (Revelation 13:7-10, 14:12-13).
...God has not appointed us unto wrath...
Amen.
Note that we can be in the tribulation without being appointed to God's wrath, for during the tribulation nobody in heaven says God's wrath "is come" until near the end of the tribulation, after the 7th trumpet (Revelation 11:15, 18), in the 7 vials of God's wrath (Revelation 15:1; Revelation 16), and none of the 7 vials are poured out on those of us who have obtained salvation; I believe we are even blessed at the 6th vial (Revelation 16:15), that we might endure to the 1,335th day after the abomination of desolation (Daniel 12:11-12), which is the day I believe Jesus will come back (Revelation 19).
I think it's important to make this distinction because many people -- including many Christians -- are going to be blaming God for everything bad that happens to them in the tribulation; they're going to be saying that God is the one causing all of their suffering, when in reality it will be Satan, evil men, and natural disasters that are causing it.
Satan is going to try to use the suffering of the tribulation to turn people -- even us Christians -- away from God, to get us to believe that God is really a cruel and unjust tyrant who only wants mankind to suffer and be tortured, while Satan is the one trying to help us. We need to be able to say, no, this suffering is not from God, but from evil and natural sources, just as we Christians have always had to suffer in wars, famines, plagues, persecutions, and natural disasters throughout history, from the beginning of the church down until this day.
In the pre-trib view, will those who "obtain salvation" in the tribulation be "appointed to wrath?" Aren't being "appointed to wrath" and "obtaining salvation" mutually exclusive?
"God hath not appointed us to wrath, but to obtain salvation by our Lord Jesus Christ" (1 Thessalonians 5:9).
