Let's just recap where we are in this study. Last week we studied the two visions unfolded in Revelation chapter seven. The visions of chapter seven actually interrupted the opening of the seven seals. The first six seals revealed the course of this age leading up to the Tribulation and the Second Coming of Jesus Christ. The end itself was announced in the sixth seal. This sequence follows very closely the way Jesus Himself described the course of this age and the end itself in Matthew chapter 24, Luke chapter 21 and Mark chapter 13.
Then, after the end was announced in the sixth seal, and before further details of the Tribulation itself are given, chapter seven unfolds two pictures of the church - one just before the Tribulation, as she is sealed and protected from the coming wrath of God - and a second picture, which is a scene of the church after the Tribulation is over, around the throne of God.
Now chapters 8 and 9 pick up the opening of the seventh seal which contains the horrific events of the seven trumpets. Remember, each of the sevens (seven seals, seven trumpets, seven bowls) continues right up to and including the end. The events build in intensity and in speed as the end approaches. The actual wrath of God (not to be confused with the persecution of the church by Satan and Antichrist) is not poured out until the very end of the age - right before the Second Coming of Jesus Christ in glory.
