Deukal:
Id like to inquire about the events of Revelations, when God's peole go to heaven and non-believers remain on earth.
Id like to know more about the Christian belief of what will happen in such an event to the non-believers?
Believers will remain on the earth with unbelievers during the coming tribulation of Revelation chapters 6-18 (Revelation 13:7-10, 14:12-13, 20:4-6). It will only be after those events are all over that Jesus will return and catch up together/gather together all believers (Matthew 24:29-31, 2 Thessalonans 2:1) into the sky to have a meeting with him in the clouds (1 Thessalonians 4:16-17). At that meeting, Jesus will judge the church (Psalms 50:4-5, cf. Mark 13:27) and then figuratively marry the church (Revelation 19:7) in the clouds, before the church mounts white horses and comes back down from the sky (the first heaven) with Jesus (Revelation 19:14) as he defeats all the armies of the unbelievers (Revelation 19:15-21). Then Jesus and the church will reign on the earth for 1,000 years (Revelation 20:4-6, 5:10, 2:26-29).
Before Jesus returns, the coming tribulation of Revelation chapters 6-18 will begin with a great war, which, with its aftermath of famines and epidemics, will end up killing one-fourth of the world (Revelation 6:4-8), both believers and unbelievers. After that war will occur a great cataclysm, possibly a huge volcanic eruption, which will affect the entire world (Revelation 6:12-14). Then will occur a series of other natural disasters, including possibly a huge shower of meteorites (Revelation 8:7), followed by the collapse of another erupting volcano into the ocean (Revelation 8:8-9), followed by a comet striking the earth (Revelation 8:10-11).
Then will occur two very strange events, which the world may try to explain as attacks by aliens, and which could in fact be controlled by demonic forces. First a huge swarm of weird, locust-like creatures will come up out of the earth and sting mankind and torment it for five months (Revelation 9:2-11). Then a gigantic army of 200,000,000 weird horse-like creatures will kill one-third of mankind (Revelation 9:16-19).
After these events are over, a human commonly called the Antichrist (the beast) will take over the world by the power of the devil (the dragon) and make everyone worship the devil (possibly as "Lucifer") and worship the Antichrist, and a living, speaking image of the Antichrist (possibly a robot and CGI), and receive his mark on their right hand or their forehead (Revelation 13:4-18), possibly via ritual scarification. Believers will have to be willing to be beheaded by the Antichrist before they would do any of these things, knowing that to do any of these things will mean eternal damnation (Revelation 14:9-13, 20:4-6).
The Antichrist will not only be empowered by the devil (2 Thessalonians 2:9), but will also be assisted by a human False Prophet who will work amazing miracles, such as calling fire down from heaven, in order to deceive the world into worshipping Lucifer and the Antichrist (Revelation 19:20, 13:13-14).
The Antichrist will be allowed to rule the world for exactly 42 months/1,260 days (Revelation 13:5, 12:6). After the Antichrist's time is up, God will send his wrath upon the followers of the Antichrist (Revelation 16), which wrath could last for 75 days. When that wrath is over, Jesus will return and bring more wrath from God, completely defeating the Antichrist and all of his armies (Revelation 19:11-21), and having the devil bound in the bottomless pit for 1,000 years (Revelation 20:1-3).
