In describing the events associated with the opening of the seven seals, John seems to take a break between the six and the seventh seal, the so called interlude, where he seems to describe two apparently unrelated visions. The vision of the 144000 who were sealed from the 12 tribes of Israel (Rev 7:1-8) and a vision of a Great Multitude from every tribe and language who had been through the Great Tribulation and appear in heaven (Rev 7:9-17).
Similarly, when John is describing the events associated with the seven trumpets, he takes a break between the sixth and the seventh trumpet, another interlude, and describes two further visions that seem somewhat unrelated. The vision of the angel and the little scroll (Rev 10:1-11) and the vision of the Gentiles trampling the Holy City for 42 months and the two witnesses prophesying for 1260 days. (Rev 11:1-14)
Post tribulationists (who believe the rapture is post-tribulation) say that the second coming of Christ to rapture the church takes place at the beginning of the last trumpet which coincides with the seventh seal. The Wrath of God is the seven bowls which are part of the seventh trumpet.
Pretribulationists (who believe the rapture is pre-tribulation) say that the second coming of Christ to rapture the church occurs at or just before the seventh seal but the trumpets, being the wrath of God, follow the seals and are not concurrent with the seals as suggested by post tribulationists.
It is, therefore, interesting to see if there is any correlation and concordance between the events mentioned in the two interludes between the sixth and the seventh seals and the sixth and the seventh trumpets.
John was given a vision of a scroll with seven seals which nobody was worthy to open but the Lamb of God who was slain and with his blood purchased for God people from every tribe and nation people and language. In the ensuing chapters, the Lamb begins to open the scroll which can only be the Book of Life. Once the Book of Life is opened, the Children of God are revealed and the Lamb Christ returns to redeem his people. It, therefore, makes sense that the rapture should take place at or just before the seventh seal is opened.
The last trumpet is also linked to the rapture of the church. (1Cor 15:51-52) It is at the seventh trumpet that the Kingdom of this World becomes the Kingdom of our Lord. (Rev 11:15) It is at the Last trumpet that God judges the nations and pours out his wrath. (Rev 11:18)
The Angel that appears in the interlude between the sixth and the seventh trumpets is holding a Little Scroll which has been opened. (Rev 10:2) This Little Scroll would appear to be the same scroll that the Lamb has been opening. Thus by the time the seventh trumpet sounds, the Book of Life has been opened.
When the Book of Life is opened, the rapture and the first resurrection take place. A Great multitude appear in heaven. The Great Multitude appearing in heaven appears between the sixth and the seventh seals.
If the Trumpets are aligned with the seals, if they recapitulate the seals and are concurrent with the seals, then the interludes would also be aligned. The opening of the Little Scroll would be concordant with the Great Multitude appearing in heaven.
What about the other events that take place in the interludes between the sixth and the seventh seals and the sixth and the seventh trumpets?
As already mentioned, the seventh trumpet is when the kingdom of this world becomes the kingdom of our lord. The Millennium is about to start. God just has to finish pouring out his wrath on the nations as the Seventh trumpet sounds.
What can be made of the vision of the Gentiles trampling the Holy City for 42 months (Rev 11:2) and the two witnesses prophesying for 1260 days (Rev 11:3) in the interlude between the sixth and the seventh trumpet?
The duration of the great tribulation will be 1260 days or 42 months which is 3.5 years. (Rev 12:6, Rev 12:14 & Rev 13:5-8) The point at which this vision is given, the great tribulation is about to end. It would, therefore, appear that the gentiles finish trampling the Holy City at the time the seventh trumpet sounds and the two witnesses also finish prophesying at this point too.
What about the 144000, when are they sealed? The 144000 taken from the 12 tribes of Israel are no doubt the Women who is pursued by the dragon in Revelation chapter 12. The woman is pursued by the dragon for 1260 days or times time and half a time. The 144000 would therefore have been sealed at the beginning of the great tribulation.
The 144000 being sealed and the woman being taken care of for 1260 days, the gentiles trampling the Holy City for 42 months and the two witnesses prophesying for 1260 days, all span the duration of the great tribulation but are not mentioned until it is almost over – just before the seventh seal or the seventh trumpet (assuming they are simultaneous).
These visions are, therefore, retrospective or recapitulations given the point at which they are mentioned.
The interludes between the sixth and the seven seal and the sixth and the seventh trumpets do appear to be concordant and concurrent with one another. The Little Scroll is opened just as the seventh seal is opened and as the seventh trumpet sounds and then the rapture takes place and a great multitude appear in heaven. Also, the 144000 are revealed having been sealed and protected for 1260 days. The Holy City has been trampled for 42 months and the two witnesses are about to finish 1260 days of prophesying.
Revelation paints a glorious picture with many elements that are described one at time rather than in time sequence.
