No, that is wrong. The Great Tribulation is during the 6th trump but God's wrath first comes at the 7th trump:
Rev 11:15 And the seventh angel sounded ; and there were great voices in heaven, saying, The kingdoms of this world are become the kingdoms of our Lord, and of his Christ; and he shall reign for ever and ever.
Rev 11:16 And the four and twenty elders, which sat before God on their seats, fell upon their faces, and worshipped God,
Rev 11:17 Saying, We give thee thanks, O Lord God Almighty, which art, and wast, and art to come; because thou hast taken to thee thy great power, and hast reigned.
Rev 11:18 And the nations were angry, and thy wrath is come , and the time of the dead, that they should be judged, and that thou shouldest give reward unto thy servants the prophets, and to the saints, and them that fear thy name, small and great; and shouldest destroy them which destroy the earth.
"They wrath has come" is also stated at the 6th seal:
"And the kings of the earth, and the great ones, and the commanders, and the rich, and the powerful, and every slave and free, hid themselves in the caves, and among the rocks of the mountains. And they say to the mountains and to the rocks, “Fall on us and hide us
b from
the face of the
One sitting on the throne, and from the wrath of the Lamb,
because the great day of Their wrath has come, and who is able to stand?”
Each of these announcements is referring to God's wrath in its fullness, which begins with the opening of the first seal and is completed with the pouring out of the seventh bowl judgment. The announcements are not markers designating where God's wrath begins, as so many have erroneously interpreted, but is referring to God's wrath in its completeness.
This proves the Great Tribulation is not God's wrath. Why would God have his own saints beheaded? That clearly isn't God's wrath against his own people.
The Great Tribulation is indeed God's wrath!
Daniel 9:27 sets the stage for the time period of God's wrath, which is seven years in length. It is the last seven years of the seventy seven year periods that were decreed upon Israel and Jerusalem. In Matt.24:15 Jesus identified the Great Tribulation as beginning when that ruler/antichrist has that abomination set up in the holy place within the temple which marks the middle of the seven years and covers the last 3 1/2 years until the Lord returns to the earth to end the age.
It is referred to as the Great Tribulation because it is when the antichrist/beast will set up that abomination in the temple, which is synonymous with the image mentioned in Revelation that the false prophet will have had the inhabitants of the earth make. It is also the time when the antichrist/beast will make war and conquer the great tribulation saints, killing anyone who does not worship the image of the beast.
Prophecy that saints would be killed during the Great Tribulation:
Rev 6:9 And when he had opened the fifth seal, I saw under the altar the souls of them that were slain for the word of God, and for the testimony which they held:
Rev 6:10 And they cried with a loud voice, saying, How long, O Lord, holy and true, dost thou not judge and avenge our blood on them that dwell on the earth?
Rev 6:11 And white robes were given unto every one of them; and it was said unto them, that they should rest yet for a little season, until their fellowservants also and their brethren, that should be killed as they were, should be fulfilled.
Those under the altar seen at the opening of the 5th seal, will be those saints who will have been killed during the first 3 1/2 years of that seven year period. Their fellow servants and brothers that they are told to wait for, are those who will be killed during the last 3 1/2 year period of that seven years, which are also referred to as the saints who come out of the great tribulation.
Satan's wrath and him starting the Great Tribulation:
Rev 12:12 Therefore rejoice, you heavens, and you 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 knows that he has but a short time.
Rev 12:13 And when the dragon saw that he was cast unto the earth, he persecuted the woman which brought forth the man child.
Rev 12:14 And to the woman were given two wings of a great eagle, that she might fly into the wilderness, into her place, where she is nourished for a time, and times, and half a time, from the face of the serpent.
Rev 12:15 And the serpent cast out of his mouth water as a flood after the woman, that he might cause her to be carried away of the flood.
Rev 12:16 And the earth helped the woman, and the earth opened her mouth, and swallowed up the flood which the dragon cast out of his mouth.
Rev 12:17 And the dragon was wroth with the woman, and went to make war with the remnant of her seed , which keep the commandments of God, and have the testimony of Jesus Christ.
The reason that Satan will be full of wrath, is because in middle of the seven years he and his angels will be thrown out of heaven, which is the result of the 7th trumpet/3rd woe and from that time forward he knows that his time is short because he will only have 3 1/2 years before the Lord returns to the earth where at which time he is cast into the Abyss for a thousand years. However, we must keep in mind that the seven years is still God's decree upon Israel and Jerusalem and not Satan's. Therefore, just because the word "wrath' is used does not mean that we should dub this as "Satan's wrath." He will just be angry in the midst of God's wrath because his time will be short.
The saints killed during Satan's wrathful Great Tribulation are resurrected:
Rev 20:4 And 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 .
This is correct in that, those saints who will have been killed during the great tribulation period will be resurrected when the Lord returns to the earth to end the age. However, it is important to understand that this is not the church which is being resurrected here, but those saints who will have died during the great tribulation, which is a part of God's wrath. The beast, his kingdom, his image and mark, all fall under the time of God' s wrath and will be a test to those upon the earth. This is why the Lord continues to warn believers throughout His word to always be watching for His appearing to gather the church so that the time of God's wrath does not close on us like a trap. For He warns believers about this:
"Be careful, or your hearts will be weighed down with carousing, drunkenness and the anxieties of life, and that day will close on you suddenly like a trap. For it will come on all those who live on the face of the whole earth. Be always on the watch, and pray that you may be able to escape all that is about to happen, and that you may be able to stand before the Son of Man.”
What would be the difference between believers who are watching and unbelievers who are not watching, if both enter into the same timer period of wrath? The answer is that, those who are watching, who are having faith and who are not living according to the sinful nature, will escape when the Lord comes to gather His church which takes place prior to the first seal being opened which initiates God's wrath. Everyone left on the earth during that time will be exposed to God's wrath via the seals, trumpets and bowl judgements, as well as the plagues that the two witnesses will bring. The reason that their will be saints on earth during the time of God's wrath, is because they will have not either been believers prior to the gathering of the church or they will have been believers who had gone back into the world willfully living according to the sinful nature.
Its Satan's wrath not God's wrath during the Great Tribulation. God's wrath begins at the 7th trump.
"I saw in heaven another great and marvelous sign: seven angels with the seven last plagues—
last, because with them God’s wrath is completed." - Revelation 15:1
The verse above is of course referring to the seven angels with the bowl judgments given in detail in chapter 16. The fact that the seven last plagues/bowls are referred to as being the "Last" plagues of wrath, infers that there would have to be wrath that comes before them. An example would be if I said, "I was the last one in line to get my concert tickets." If I'm last in line, it means that there would have been other people in front of me. It is the same here. Since the seven bowl judgements as a unit complete God's wrath, then there will have to be other wrath that comes before them, namely, the seals and trumpets.
