Two witnesses will be Enoch and Elijah who never experienced deathWho are the two witnesses? I am very sure that it will be Enoch, and Esau, two who have not faced the whole it is appointed man once to die, and then the judgement. These two have never died. It fits like a glove.
This is why the rapture is a thing. Egypt was the location, but Goshen was separated from Egypt half way through the plagues (approximately). However, the Great Tribulation is not going to be a city, or a country, but the whole world. There is only one way to separate the church from the world, according to Paul, which is for the church to leave the world.
The church is not going to be there. Just as Goshen was separated from Egypt, so the church will be separated from the world.
You failed to understand what Paul is saying in Ephesians. We are sealed by the Holy Spirit as a guarantee of our inheritance until we take possession of it. In other words, we are sealed as belonging to God, and not to the world/Satan. This is why some (many?) Christians believe that believers cannot be possessed by demons. We are God's possession, filled by the Holy Spirit. Demons cannot take God's possession from Him, by possessing believers. This is also given as a reason why, when researching Alien abductions, there is not a SINGLE record of a born again believer being abducted, or visited. There are records of people who, in the process of being abduction, cried out to Jesus, and it ended at that moment.
You are forcing this onto Revelation. The only sealed on Earth during the tribulation are the 144,000, who are marked in Revelation. Their purpose is to go out preaching the gospel to those who are still on Earth. They are protected because they have God's mark on their forehead. (It is already different already.) They also preach destruction on the kingdom of the beast and his image.
So only the 144000 will not be affected.
Which is why it may not be a pretrib rapture, but a midtrib rapture, as Goshen was not separated from Egypt until half way through the plagues.
Don't allegorize prophecy. Jesus first coming was literally prophesied, and rather exactly. God has not changed, so there is no reason not to believe that Jesus second coming is prophesied literally as well. This is why church fathers and others say, if you take the second coming prophecies literally, premillennialism is all that is left.
There is no such thing as a pre-trib rapture found in scripture, it's a fabricated fairy tale of men, namely John N. Darby 1830's & C.I. Scofield 1909
No such things as aliens abducting humans on earth, sci-fi propaganda
The 144,000 will be saved and sealed by the Holy Spirit, and "Added" to the church present on earth during the tribulation
Jesus Is The Lord
