When it comes to prophecy concerning a possible alien deception, there really hasn’t been any video or blog I’ve seen that I felt truly gave the subject justice as a hypothetical scenario.
The main reason they site a possible Alien thesis is to explain where all the Pre Trib Raptured Saints disappear to, but that whole thesis misunderstand the Rapture. No one disappears, we will be CHAGED, simply meaning we leave our flesh body, because our sin flesh can not enter heaven, and thus our spirit man goes to be with the Lord, where we get our new glorious bodies (white robes).
There is no one left to trick, the majority of those left hate God or the idea of God, as we see now, they are all basically Anti-God bigots running the nations of earth. There will be Gentile Christian Saints who thus become Martyrs, the 1/3 Jewish (Israel) peoples who repent (3.5-5 million Jews) will be protected by God for a reason, so there can be a Kingdom Age via Jesus ruling on David's throne. Thus only those Jews in hiding for 1260 days in the Petra/Bozrah area does the Anti-Christ and false prophet try to trick via miracles etc. but to no avail, but why? Jesus told us in Matt. 24:24-27, he says IF IT WERE POSSIBLE they would deceive the very elect (Jews who repent are those elect). So, this means it IS NOT POSSIBLE right? Logic prevails here, so why is it not possible to deceive those Jews in Petra? Well, Jesus tells us, he says if you hear of me in the desert don't believe it, or if you hear of me in a Secret Storage Room (Store room), do not believe it, for I will be coming in the Eastern Skies for all men to see. So, Jess tells them, ONLY look fir me in the Eastern Skies !! So, the Anti-Christ is living in Jerusalem, he thus can not be the Messiah !! These are the only people he needs to deceive, everyone else he can get at, including the Gentiles who become Christians, they are the Martyrs under the 5th Seal, most are worshiping him tbh, but he will kill many, like all Muslims who refuse to worship him, hey, if they blow up bombs for Allah, they will not worship a man, many I assume will come to Christ during this 70th week, realizing all the things Jesus foretold are the deep truths.
