that would be wrong!
There is no sign for the rapture. It can happen any time. You however have a sign. All one has to do is read teh bible, see what plagues befall with what trumpet. They can know when the sixth trumpet sounds and the disaster that follows and then would know that the rapture is very very quick!
That thinking of course is from men's leaven doctrines gotten from those in 1830's Great Britain like John Nelson Darby. He got his false Pre-tribulational Rapture theory from the Edward Irving church movement, and Cyrus Scofield created a study Bible pushing the theory. It's just a theory from men though, not... actual Bible Scripture.
So when you act like it is... Bible Scripture, you are only deceiving yourself.
Per the Book of Revelation, Jesus' 2nd coming, which is His only... coming return we are still waiting for today, is on the 6th Seal, 7th Trumpet, and 7th Vial.
6th Seal - Rev.6, shows the events of the "day of the Lord" which is the time of that 'wrath', on the last day of this world.
7th Trumpet - likewise shows that time of God's wrath upon the wicked, and it shows The Father and Son have taken reign over all nations, which is a "day of the Lord" event per God's prophets.
7th Vial - the day when the battle of Armageddon happens, which is a "day of the Lord" event for the last day of this world when Jesus returns to fight with His angel army.
From the end of Rev.8 thru to Rev.11:15 covers 3 Periods for the end:
5th Trumpet - 1st Woe = first period leading up to the "great tribulation"
6th Trumpet - 2nd Woe = the "great tribulation" timing
7th Trumpet - 3rd Woe = time of Christ's coming with His army to do battle and take reign over all nations.
Thus to infer there is no sign of Christ's coming on those timings is to be totally deceived away... from the actual written Bible Scripture.
