Rev 6:12-13 I looked when He opened the sixth seal, and behold, there was a great earthquake; and the sun became black as sackcloth of hair, and the moon became like blood. And the stars of heaven fell to the earth, as a fig tree drops its late figs when it is shaken by a mighty wind.
The great earthquake will bring everyone into the open space and all men will witness God's miracle of covering planet earth. As the whole universe is covered, the stars and sun will become black. With no light from the sun the moon will turn to blood red and then black. With the whole heaven blacken, our Lord Jesus coming His heavenly hosts of angels will appear as stars falling to the earth. Trumpets will be sounded to herald in the King of Kings. As they approach nearer all men will see our Lord Jesus and the dead in Christ will rise first followed by His elects (Christians who had not taken the mark of the beast or 666) and they will meet the Lord in the cloud and will be with Him forever. This is what we termed as 'Rapture'.
The journey of these Elects
These are all from the remnants of Christians preserved by God and the new converts during WW3. With God's nourishment during WW3 and the power of God in the hands of elects, majority of those not killed by the wars, earthquakes, pestilences, famines, etc. will come to the saving Grace of our Lord Jesus Christ. Elects (true Christian leaders) will disciple these new converts based solely on the words of God so that they are just like the NT church, sharing, caring, protecting and loving one another. They too will be taught in great details the End Time Events.
Act 4:32-33 Now the multitude of those who believed were of one heart and one soul; neither did anyone say that any of the things he possessed was his own, but they had all things in common. And with great power the apostles gave witness to the resurrection of the Lord Jesus. And great grace was upon them all.
Period of Tribulation or Sorrows
Mat 24:9 "Then they will deliver you up to tribulation and kill you, and you will be hated by all nations for My name's sake."
So after WW3, the Antichrist will rebuild the abominable temple of God for the 'One World Religion', where our Lord Jesus Christ is compromised of His divinity and accepted only as a prophet of Allah or God. The elects, by rejecting this heresy, abominable temple of God and the microchip 666, knew that the misled and deceived public will persecute and kill them. During the martyrdom of some elects, all nations will hear the gospel of Jesus preached by the Holy Spirit dwelling in them.
Warning -some will fall as they do not appreciate God's love, grace and truth, thus they are lazy to want to understand Him and His words.
The Great Tribulation
The temptation of riches, honour, great power and happy and joyful families against poverty, starvation and curses and cries from suffering families will not be able to deceive these elects whom the Father Himself is dwelling within them.
Mat 24:30-31 "Then the sign of the Son of Man will appear in heaven, and then all the tribes of the earth will mourn, and they will see the Son of Man coming on the clouds of heaven with power and great glory. And He will send His angels with a great sound of a trumpet, and they will gather together His elect from the four winds, from one end of heaven to the other."
These elects will be with the Lord on His throne for just like the martyrs they too have overcome Satan and his deceptions.
