The days of the voice of the seventh angel will the time, times, half time that Satan will have left.
That does not make sense in light of the following, for one.
----------------
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.
Revelation 6:15 And the kings of the earth, and the great men, and the rich men, and the chief captains, and the mighty men, and every bondman, and every free man, hid themselves in the dens and in the rocks of the mountains;
16 And said to the mountains and rocks, Fall on us, and hide us from the face of him that sitteth on the throne, and from the wrath of the Lamb:
17 For the great day of his wrath is come; and who shall be able to stand?
Isaiah 2:17 And the loftiness of man shall be bowed down, and the haughtiness of men shall be made low:
and the LORD alone shall be exalted in that day
18 And the idols he shall utterly abolish.
19 And they shall go into the holes of the rocks, and into the caves of the earth, for fear of the LORD, and for the glory of his majesty, when he ariseth to shake terribly the earth.
20 In that day a man shall cast his idols of silver, and his idols of gold, which they made each one for himself to worship, to the moles and to the bats;
21 To go into the clefts of the rocks, and into the tops of the ragged rocks, for fear of the LORD, and for the glory of his majesty, when he ariseth to shake terribly the earth.
2 Thessalonians 2:4
Who opposeth and exalteth himself above all that is called God , or that is worshipped; so that he as God sitteth in the temple of God, shewing himself that he is God.
-----------------------------
Take note of what I underlined above. Does it really make sense that what I underlined in Isaiah 2, that that is true if 2 Thessalonians 2:4 is still true at the time? Clearly, 2 Thessalonians 2:4 is involving the 42 month reign of the beast. Clearly, what I underlined in Isaiah 2 comes to pass once Revelation 11:15 is fulfilled.
Apparently, per your interpretation, you would have us believe--- Who opposeth and exalteth himself above all that is called God(2 Thessalonians 2:4)---equals this---the LORD alone shall be exalted in that day(Isaiah 2:17).
You are convinced you have this all figured out and are right about everything, regardless that your interpretation defies common sense, since common sense says the Lord alone can't be exalted in that day if the one meant in 2 Thessalonians 2:4 is exalting himself in that day. Obviously then, once the 7th trumpet sounds, the one meant in 2 Thessalonians 2:4 will no longer be exalting himself, the Lord alone, just like Isaiah 2:17 declared, will be exalted in that day.
