Revelation: Chapter 8 Timelines
Setting
Revelation 8:1-13 describes several events that take place. The first is the opening of the 7th seal, and 30 minutes of silence in heaven, depicted in the graphic within the dashed red oval.
The next event was John witnessing the trumpets being distributed to seven angels, with the eighth receiving the censer. In total, there are eight angels and the golden censer filled with the prayers of the saints that the eighth angel was to present on the golden altar before the throne of God, Revelation 8:3.
The next chart illustrates the sounding of the first trumpet.
The sounding of the second trumpet is illustrated in the following chart.
The sounding of the third trumpet is Illustrated next.
Next is the sounding of the fourth trumpet.
Finally, there is the announcement of the coming three woes.
All of these events occur during the first half of the tribulation period. An important aspect of the graphic of the combined timelines in chapter 8 that follows is that not all the trumpets affect the earth and its inhabitants for the entire duration remaining in the tribulation after the trumpet is blown, except for the fourth trumpet. The first three trumpets seem to have a diminished impact on the earth and its inhabitants once blown, both temporally and spatially.
