The Seals, Trumpets and Bowls are 3 accounts pertaining to the same thing. Just as Matthew, Mark and Luke are three eye witness accounts of the same events.
The Seals, Trumpets and Bowls culminate at 6-6-6 with the height of Satanic Influence and Evil. The Lord's Kingdom is established at 7-7-7. The Seals show events as seen by Man. Read the 1st Seal with the 1st Trumpet with the 1st Bowl, etc.
Let's look at the 6th of each:
6th SEAL:
[SUP]15 [/SUP]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;
[SUP]16 [/SUP]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
6th TRUMPET:
[SUP]18 [/SUP]By these three was the third part of men killed, by the fire, and by the smoke, and by the brimstone, which issued out of their mouths.
6th BOWL:
[SUP]16 [/SUP]And he gathered them together into a place called in the Hebrew tongue Armageddon.
So the 6th of each describes one event - THE BATTLE OF ARMAGEDDON - where Christ returns
The 7th of each describe the Kingdom of the Lord.
7th SEAL:
And when he had opened the seventh seal, there was silence in heaven about the space of half an hour.
7th TRUMPET:
[SUP]7 [/SUP]But in the days of the voice of the seventh angel, when he shall begin to sound, the mystery of God should be finished, as he hath declared to his servants the prophets.
[SUP]15 [/SUP]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.
7th BOWL:
[SUP]17 [/SUP]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.
