This description fits what the state of things will be like
And immediately after the suffering of those days, the sun will be darkened and the moon will not shine its light. And the stars will fall from heaven and the powers of heaven will be shaken. And then will be seen the sign of the Son of man in heaven... And he will send his (angels) with a large trumpet and they will gather his chosen ones from the four winds from one end of heaven to the other.
The main body of the rapture theory was invented by Ribera, a Catholic Jesuit theologian who published his work shortly after the Massacre of St. Bartholomew in 1572. Protestants were pointing to the Vatican as the harlot beast system of Revelation. The blood of that horrific Catholic inspired massacre of French Protestants was still being washed off the streets of Paris when the Jesuits presented their rapture theory, designed to take pressure off the Catholic Church system.... The Jesuits also peddled that 'the saints' would not be on Earth during the time of tribulation....
The word "rapture" comes from the Latin 'rapere' used by the Vulgate to translate the Greek word 'harpaz', which is rendered by the phrase "caught up" in most English translations.
Matthew 24:15 ~ And when you see the sign of uncleanness and desolation, that was spoken of by Daniel the prophet, which will stand in the Set Apart place, he that reads, let him understand.
Daniel 9:27 ~ During one week he will make a firm covenant with many. For half a week he will put a stop to the sacrifice and meal offering. At the corner of the altar (in the Set Apart place) will be an appalling abomination until the decreed destruction will be poured down upon this appalling thing.
