You're still conflating wrath with tribulation. Christians will be martyred during the great tribulation:
Revelation 20:4
4And I saw thrones, and they sat upon them, and judgment was given unto them: and
I saw the souls of them that were beheaded for the witness of Jesus, and for the word of God, and which had not worshipped the beast, neither his image, neither had received
his mark upon their foreheads, or in their hands; and they lived and reigned with Christ a thousand years.
The great tribulation is not God's wrath, but rather it is Satan's wrath:
Revelation 12:12
12Therefore rejoice,
ye heavens, and ye that dwell in them. Woe to the inhabiters of the earth and of the sea! for the devil is come down unto you, having great wrath, because he knoweth that he hath but a short time.
I would suggest that you go and look up all scriptures regarding "The Day of the Lord" and understand what that time period entails. This time period is what the majority of the book of Revelation is covering, i.e. the things/events which must take place in quickness.
Correct. Christians are spared the wrath of hellfire and damnation and the bowls. The bowls of wrath happen after the tribulation is over.
Closely notice that 1 Thessalonians 4:15-17 says nothing about a pre-tribulational gathering of the church. No where is that mentioned. You're preaching a false doctrine.
Yes, the day of the Lord will come like a thief in the night
after the tribulation. Like sudden destruction in the days of Noah:
Matthew 24:42-44
42Watch therefore: for ye know not what hour your Lord doth come.
43But know this, that if the goodman of the house had known in what watch the thief would come, he would have watched, and would not have suffered his house to be broken up.
44Therefore be ye also ready: for in such an hour as ye think not the Son of man cometh.
In verse 3, Paul says that "while people (unbelievers) are saying "Peace and security" destruction will come upon them suddenly, like labor pains on a pregnant woman, and they will not escape."
Then in verse 4, he says "But you, brothers, are not in darkness so that this day (the Day of the Lord) should overtake you like a thief.
"But you, brothers" immediately infers the opposite of not escaping, i.e. where unbelievers will not escape that sudden destruction of God's wrath, believers in Christ will via the event described in 1 Thess.4:15-17, which Paul previously wrote about.
I mostly agree with this part. I think the main thing we disagree on are pre-trib and what is God's wrath verses tribulation.
I strongly encourage you to compare Isaiah 13:6-13, Matthew 24:29, and the 6th Seal in Revelation 6:12-17.
Read the next chapter too. 1 Thessalonians 5:1-10. It is not talking about the gathering of the church being literally or figuratively in the day or night. The day and night is referring to our conduct as Christians. While the master is away, don't be squandering your grace and liberty getting drunk, sinning, etc.
6So then, let us not be like others, who are asleep, but let us be awake and sober.
7For those who sleep, sleep at night, and those who get drunk, get drunk at night.
8But since we belong to the day, let us be sober, putting on faith and love as a breastplate, and the hope of salvation as a helmet.
The comfort Paul was talking about was the resurrection, rapture, and being with Jesus. Closely notice Paul is addressing the concern in 1 Thess. 4:13
13Brothers and sisters, we do not want you to be uninformed about those who sleep in death, so that you do not grieve like the rest of mankind, who have no hope.
