The number one argument that draws people to the Pre-tribulation rapture doctrine that Christians will be rapture out before the Great tribulation is the fact that Christians are not assigned or appointed to God’s wrath. The problem is that the nature of God’s wrath is assumed and defined contrary to God’s Word. Lets look at the verse:
1 Thess. 5:9,10 (KJV) For God hath not appointed us to wrath, but to obtain salvation by our Lord Jesus Christ, Who died for us, that, whether we wake or sleep, we should live together with him.
(NASV)9 For God has not destined us for wrath, but for obtaining salvation through our Lord Jesus Christ, 10 who died for us, so that whether we are awake or asleep, we will live together with Him.
So we understand that …in the future….. we are not appointed, assigned, or destined to God’s wrath. The question that needs to be asked is “what does that apply to?” Instead many just ASSUME that it refers to a ‘temporal’ wrath on Earth. However does it? The answer is a resounding “NO!” The wrath that ‘is to come’ is Hell itself.
There are two words used in the Greek language that often translates into English as “wrath.” The one used in this passage is “thymos” it is present in only two passages in Revelation… Rev. 6:16,17, and Rev. 11:18
In Rev. 6, MAN defines the events happening to Earth as God’s wrath, but in Rev. 11:18 the 24 elders define God’s wrath as Hell, or judging the dead.
The other word in the Greek used for God’s wrath starts after Rev. 11 and is used in the bowl/vial judgements. In Rev. 14:9-11 the angels define EXACTLY what God’s wrath is:
 And the third angel followed them, saying with a loud voice, If any man worship the beast and his image, and receive his mark in his forehead, or in his hand,
 The same shall drink of the wine of the wrath of God, which is poured out without mixture into the cup of his indignation; and he shall be tormented with fire and brimstone in the presence of the holy angels, and in the presence of the Lamb:
 And the smoke of their torment ascendeth up for ever and ever: and they have no rest day nor night, who worship the beast and his image, and whosoever receiveth the mark of his name.
Here the picture of God’s wrath is once again… ETERNAL in nature… fire and brimstone with smoke that ascends up eternally.
Okay, this is the basic argument and anyone can twist the Scriptures to suggest what they want it to suggest, so let’s look at the application.
First of all, the pretrib doctrine separates the church from the tribulation saints in the book of Revelation. The argument is that the church/bride cannot experience God’s wrath therefore she must be raptured out of that mess. Are you seeing a problem yet? What about the “tribulation saints?” Are they appointed to God’s wrath? Does God’s Word not apply to them? In my other posts, I’ve addressed this issue in more detail. The fact of the matter is that God’s promises apply to all of God’s people. In order for God’s wrath to temporal, God’s Word would be a lie to the “tribulation saints.” God’s Word does not lie, therefore God’s wrath is not temporal, but Hell itself.
So the very foundation of the pretrib doctrine has now been destroyed. Without the speculation that states that God’s wrath is not Hell, but Earthly, any basis for placing the rapture at the beginning of the tribulation has been dismantled. Understanding that God’s wrath is indeed Hell, leaves no Biblical argument for skipping out of the great tribulation. Without the wrath of God being temporal, the pre-trib rapture doctrine ceases to exist.
