Rev 15 starts with wrath poured out but is in no way the second coming at the end of the 7yr gt.
Explain all this;
Rev16
14 For they are the spirits of devils, working miracles, which go forth unto the kings of the earth and of the whole world, to gather them to the battle of that great day of God Almighty.
15 Behold, I come as a thief. Blessed is he that watcheth, and keepeth his garments, lest he walk naked, and they see his shame.
16 And he gathered them together into a place called in the Hebrew tongue Armageddon.
17 And the seventh angel poured out his vial into the air; and there came a great voice out of the temple of heaven, from the throne, saying, It is done.
This is all happening well into the wrath part of the 7 yr gt.
Placing the second coming at the end of the 7 yr gt.
Now let's look at Rev 6 thru Rev 11. You need to understand what you are reading.
As I said, the seals happen in order 1 thru 7.
Revelation 6 contains the 1st 6 seals; the great tribulation is the 5th seal and Jesus comes at the 6th seal.........immediately after the tribulation
Then the 7th seal is opened, and the wrath of God begins. Then we go through the trumpets of wrath.
Jesus returns for Armageddon and then sets up His kingdom on earth
So after reading Revelation 6, 7, 8, 9, 10, and 11. You have the complete story. Armageddon is over and Christ Has set up His millennial kingdom on earth at the 7th trumpet.
Revelation 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.
The story is over. We are in the millennial kingdom in Revelation 11.
You can throw away Revelation 12, 13, 14, 15, and 16. You don't need them. You already have the story.
Do you want some more information about the story you already have? Then read Revelation 12. It begins before the story you already have and takes you to the point of great tribulation when the dragon goes after the seed of the woman because he can't get to the woman.
Do you want some more information about the story you already have? Read Revelation 13 and 14. These events happen during the 1st 6 seals, which is the time of the tribulation. Here is the great tribulation which is the 5th seal.
Revelation 14
13 And I heard a voice from heaven saying unto me, Write, Blessed are the dead which die in the Lord from henceforth: Yea, saith the Spirit, that they may rest from their labours; and their works do follow them.
Here is the coming of Jesus which is the 6th seal
Revelation 14
14 And I looked, and behold a white cloud, and upon the cloud one sat like unto the Son of man, having on his head a golden crown, and in his hand a sharp sickle.
15 And another angel came out of the temple, crying with a loud voice to him that sat on the cloud, Thrust in thy sickle, and reap: for the time is come for thee to reap; for the harvest of the earth is ripe.
16 And he that sat on the cloud thrust in his sickle on the earth; and the earth was reaped.
Do you want more information about what is happening in Revelation 7 and those that come out of great tribulation. Read Revelation 15
Do you want more information about the 7th seal wrath of God. Read Revelation 16.
You get two views of the same story.
Revelation 6, 7, 8, 9, 10 and 11, tell you the story.
Revelation 13, 14, 15, and 16 gives you more information of what occurs in that story.
Rev 12 gives you a little more information.
