Joseph Smith was told by God that the 7 seals are 7 1000-year periods of the earth history. The 7 Seals make mention of the emergence of disease and earthquakes. It is likely disease and earthquakes had always existed, but the the devastation is a result of how these natural occurrences are magnified due to man's changing living conditions.
6 Q. What are we to understand by the book which John saw, which was sealed on the back with seven seals?
A. We are to understand that it contains the revealed will, mysteries, and the works of God; the hidden things of his economy concerning this earth during the seven thousand years of its continuance, or its temporal existence.
7 Q. What are we to understand by the seven seals with which it was sealed?
A. We are to understand that the first seal contains the things of the first thousand years, and the csecond also of the second thousand years, and so on until the seventh.
12 Q. What are we to understand by the sounding of the trumpets, mentioned in the 8th chapter of Revelation?
A. We are to understand that as God made the world in six days, and on the seventh day he finished his work, and sanctified it, and also formed man out of the dust of the earth, even so, in the beginning of the seventh thousand years will the Lord God sanctify the earth, and complete the salvation of man, a. . . . and the sounding of the trumpets of the seven angels are the preparing and finishing of his work, in the beginning of the seventh thousand years—the preparing of the way before the time of his coming.
Seal 1 4000-3000bc: men divide up the land
Seal 2 3000-2000bc: men fight over boarders, before seal 1 you didnt have much war because if you wanted some land it was easier to just move and find some then to kill over it.
Seal 3 2000-1000bc: Phoenecians invent money
Seal 4 1000-0: money allows people to live in cities. Living in cramped cities then diseases and plagues became a big issue.
Seal 5 0-1000ad: Christ is crucified and Christians are martyred.
Seal 6 1000-2000ad: sun,moon, stars darkened describes the Apostasy. Apostasy describes the time when all spiritual light from heaven is rejected for the ideas and interpretations of man. Not one stone is left upon another of the temple (church) of Christ. This led the world in the DARK AGES.
Earthquakes terrorize the people because this is the century when the Romans invented concrete and cement. Consequently many cities were built with unreinforced concrete and the same type of thing we saw happen in Haiti happened in many other cities.
Regional Earthquakes and Tsunamis are signs of the time. They only affect small regions but give us a glimpse of what a world-wide catastrophe during the tribulation could do. If what happened to Haiti happened everywhere, Haiti would not receive any help because everyone would be needing help at the same time. That is why Rev says after the first trumpet will burn 1/3 trees (richer people) but burn all the green grass (poorer people). Dying in the tribulation doesn't mean you are righteous or wicked.
Another angel appears with the seal of God describing the restoration of the everlasting gospel and the elect receive the sealing in the forehead. This restoration describes the Restoration by Joseph Smith of the Church of Jesus Christ of Latter-day Saints and the Restoration of the New Testament Temple and Everlasting Temple Covenant.
Seal 7 2000-3000ad:
This seal opens with a 1/2 hour of silence. this 1/2 hour could be 21 years and is not likely going to end in 2012.
The 7 Trumpets sound signaling the Tribulation
The Beast (false gov) turns against and devours the Harlot (false religion)
The righteous come out of the tribulation sanctified and with their robes washed white in the blood of the Lamb. The wicked still do not repent.
The righteous are raptured during the 7th Trumpet at the end of the Tribulation
The 7 Cups of Wrath are then poured out and the wicked are destroyed
Christ and the righteous enjoy a period of Paradisaical Peace
The Wicked are resurrected at the end of the Millennium and Satan is again empowered and there is a final Battle of God and Magog.
We are currently in the 1/2 hour silence of the 7th Seal. Soon the 7 Trumpets will sound. Signs of the times are regional disasters like Haiti and the Indonesian Tsunami which only give us a glimpse of what world-wide catastrophe could do. It would not take very much to disrupt the food supply and transportation system. Food is not locally grown any more in amounts to support large cities. Therefore, every family needs a 1-2 year supply of food and medicines. Summer is nigh at hand
