“After these seven thunders uttered their voices, the injunction comes to John as to Daniel in regard to the little book: “Seal up those things which the seven thunders uttered.” These relate to future events which will be disclosed in their order. Daniel shall stand in his lot at the end of the days. John sees the little book unsealed. Then Daniel’s prophecies have their proper place in the first, second, and third angels’ messages to be given to the world.” SDA Bible Commentary, Vol 7, pg 971
The seven thunders represent the Millerite time period, the proclamation of the first and second Angel’s messages. These messages are to be run parallel with the third and are repeated in the fourth Angel’s message of Revelation 18; “And after these things I saw another angel come down from heaven, having great power; and the earth was lightened with his glory. And he cried mightily with a strong voice, saying, Babylon the great is fallen, is fallen, and is become the habitation of devils, and the hold of every foul spirit, and a cage of every unclean and hateful bird. For all nations have drunk of the wine of the wrath of her fornication, and the kings of the earth have committed fornication with her, and the merchants of the earth are waxed rich through the abundance of her delicacies.” Revelation 18:1-3
The first and second Angels first sounded their messages during the Millerite time period from 1798 to 1844. We are now under the sounding of the fourth Angel of Revelation 18, when the first and second will be repeated. This chart shows how the Millerite history (the time of the first and second Angels messages) is repeated in our time.
