TRIBULATION PERIOD:the Tribulation begins, I believe, between 2022 and 2036 with no pre-trib rapture This is the period that Russian scientists predict an asteroid will strike the earth.
There will be, after the seventh seal is opened, seven angels sounding trumpets during the Tribulation :
Trumpet 1: The first angel sounds in Revelation 8:7 and plasma from the sun is hurled into the earth causing massive fires. This event is followed by an earthquake and perhaps like the one that occurred in 2004.
Trumpet 2: The second angel sounds in Revelation 8:8 and an asteroid strikes the sea destroying many ships.
Trumpet 3: The third angel sounds in Revelation 8:10-12 and a second asteroid strikes the earth which poisons the water and underground rivers will become contaminated. Many will die from poisoned water.
Trumpet 4: The fourth angel sounds in Revelation 8:12 and violent volcanic eruptions will occur whereby debris in thrown upward thus blocking out the sun and causing world famine. According to Revelation, one-fourth of Earthís population will perish from these first four judgments.
Trumpet 5: The fifth angel sounds in Revelation and God has put the whole world in a terrible situation because He knows it is the best way to get peopleís undivided attention. Before the Great Tribulation begins, God-Jehovah will anoint 144,000 servant messengers with Holy Spirit power. These people, from the tribes descended from the children of Israel, including the tribe of Manasseh but excluding the tribe of Dan, will speak for God for 42 months. They will proclaim the gospel of Jesus Christ to humanity.
After the Great Tribulation begins, God permits that serpent, Satan himself, to appear on Earth physically. Satan will come with millions of angels and he will masquerade as Almighty God. (Revelation 9:1-11; 2 Thessalonians 2:1-12; Revelation 13:11-18) Satan the devil is the dreaded Antichrist. Deceptively cloaked in brilliant light and charming benevolence, Satan will claim that he is God-Jehovah. He will declare that he has come to establish a thousand years of peace on Earth. At this time, there will be three identifiable types of people. The first group of people is those who have rejected Satan and decided to follow the leading of the Holy Spirit. The other group of people will readily receive satan as God because of the miracles he performs. The third group of people will defy both Satanís demands and the prompting of the Holy Spirit because they refuse to obey anyone. Since God-Jehovah is separating the people of Earth into two camps, He will allow the devil to inflict great pain and suffering upon this third group of people who have chosen to defy both God-Jehovahís and the devilís authority. Fortunately, Satan will not harm the saints with this affliction.
