No, Jesus descends to earth accompanied by his angels - 45 days after the 6th seal. The 6th seal when the sign of the Son of Man first appears in heaven. The sign will be Jesus, sickle in hand.
There is no 45 day warning period of the Second Coming. The church will have no warning when the Second Coming happens. It is a thief in the night, twinkling of an eye event. It is not a "45 days to prepare" event.
The 7th Trumpet is not the 3rd woe. The 7th Trumpet declares Jesus is now King over every nation, because the harvest is
over.
Revelation 11:1-13 is a parenthetical describing events after the 7th Trumpet. This is God's perspective of the 7th Trumpet. Revelation 13 is the 3rd woe, Satan's perspective of what may happen during the 7th Trumpet.
You have the Seals describing Revelation 13. The Seals are not the 3rd woe. The Seals are the signs of the Second Coming, but no one will realize they are happening or have happened. Some even claim they started in the first century or hundreds of years ago.
Jesus and the angels are on the earth during the Trumpets and Thunders. That is what Jesus expressed in Matthew 13 and in Matthew 25. The final harvest does not start in Revelation 20. The 144k are sealed before the 7th Seal is even opened. The church is removed from the earth in the 5th Seal. The sheep are gathered in the first 6 Trumpets. The wheat is gathered in the Thunders. But not just the redeemed are gathered. The lost are being tossed into the LOF at the same time. By the 7th Trumpet, the majority of the population on earth will be gone, way before the FP and image is brought to life. The winepress gathered in Revelation 14 is the gleaning, the left overs after the final harvest. Revelation 14 is sans the 3rd woe. Armageddon is the same winepress with the 3rd woe. The beheaded are part of the gleanings. But the third woe only happens if God extends time for those beheaded souls to make that choice to be beheaded.
Satan only has 3.5 days after the 7th Trumpet starts to sound. 42 months later at Armageddon, the only humans will be those who show up at Megiddo. The 3.5 days in Revelation 11:11 is the last half of the week of the 7th Trumpet. When the 7th Trumpet stops sounding, that will be the end of Adam's transgression. Once the 7th Trumpet stops sounding, Daniel 9:24 will be the reality on earth. The earth will be regenerated as a new heaven and earth for the Day of the Lord.
If you place the 7th Trumpet it should start with 3.5 days, then a 42 month interruption, then the 3.5 days the 7 vials are poured out. Sunday between 5pm and 6pm is the one hour battle of Armageddon. That is the end of the 7th Trumpet.
Otherwise the 7th Trumpet sounds for 7 days, then the Day of the Lord starts when the 7th Trumpet stops. Satan is bound sometime during that week. Since there is no 42 month extension, no one will be beheaded. Revelation 14 is the removal of the last of Humanity before the 7th Trumpet stops sounding.
That is how Daniel 9:27 should be interpreted in light of the book of Revelation with two 3.5 day periods making up a week of days, not a week of years. This verse is describing the days of the 7th Trumpet. That is if there is a 42 month interruption of Satan's 42 months.
Only when God as the Prince to come, Jesus Christ confirms the Atonement Covenant with the many, those left as the gleanings after the final harvest of Matthew 13 and Matthew 25, will we know if there is even a 42 month period or not.
The final harvest is not after every one is dead. The final harvest is the ending of this physical body. Many get Matthew 24:22 wrong.
"And except those days should be shortened, there should no flesh be saved: but for the elect's sake those days shall be shortened."
That does not mean spared their physical life. That means redeemed. The logical point Jesus is making is that if the GT does last for 3.5 years while He and the angels are gathering the final harvest, more souls would be tossed into the LOF thus not saved/redeemed. That would mean only thousands were raptured as the church. But if billions are taken away as the church, the GT will be shorter, because there will be less to toss into the LOF. Also a short GT, and the more tossed into the LOF, the less likely any one will be left to behead, so no 42 month extension. Remember that it is for the elect's sake. If all the elect are chosen in the final harvest, the earth would also not have to suffer the Abomination of Desolation, which is not for the elect's sake, but for the will of Satan just because some elect are still alive after the 7th Trumpet is sounded. Not having Satan's 42 months is also shorter time. Extending time past the point time is supposed to end is definitely not making time shorter. So those looking for a full 7 years of judgment are not viewing the end for the elect's sake. They are proclaiming time for the lost to enjoy their last years on earth to the fullest.
