This is because, during tribulation, saints will be judged on both faith and works in order to be saved. An example of works would be to resist the mark of the beast.
As the Book of Revelation mentions, it is by both blood of the lamb and word of testimony that they shall overcome, how they will be living their lives counts as well.
Revelation 12:12 Therefore rejoice, ye heavens, and ye that dwell in them. Woe to the inhabiters of the earth and of the sea! for the devil is come down unto you, having great wrath, because he knoweth that he hath but a short time.
We can see from the passage above there is more than just one heaven. Satan has been kicked out from both third and second heaven, where the stars are placed. As for the so-called UFOs, it’s indicated that they come from both above and below on earth as well.
Revelation 12:13 And when the dragon saw that he was cast unto the earth, he persecuted the woman which brought forth the man child.
This again proves that Jews have to go through the tribulation, and we Christians won’t have to.
Revelation 12:14 And to the woman were given two wings of a great eagle, that she might fly into the wilderness, into her place, where she is nourished for a time, and times, and half a time, from the face of the serpent.
This means that during the tribulation, the Jews will take air transport like airplanes to flee from the Antichrist. The latter part of the passage mentioning time, times and half a time, that could mean three and a half years, which is parallel to the prophesied timeline.
Matthew 24:19-20 And woe unto them that are with child, and to them that give suck in those days! But pray ye that your flight be not in the winter, neither on the sabbath day:
The Bible is clearly prophetic about what would happen in the future during the tribulation. Matthew 24 supports the type of transport that the Jews will be taking to try to escape from Antichrist’s persecution and system.
Revelation 12:15 And the serpent cast out of his mouth water as a flood after the woman, that he might cause her to be carried away of the flood.
This explains how Satan will want to destroy Israel with a flood. It somehow seems like he wants to imitate how God judged him and the fallen angels and decided to drowned them all with the universal flood as mentioned in Genesis 6-7.
Jeremiah 47:2 Thus saith the Lord ; Behold, waters rise up out of the north, and shall be an overflowing flood, and shall overflow the land, and all that is therein; the city, and them that dwell therein: then the men shall cry, and all the inhabitants of the land shall howl.
This supports the fact that the flood will be real as mentioned in the book of Jeremiah.
Daniel 9:26 And after threescore and two weeks shall Messiah be cut off, but not for himself: and the people of the prince that shall come shall destroy the city and the sanctuary; and the end thereof shall be with a flood, and unto the end of the war desolations are determined.
This is another proof of the future flood caused by Satan.
Revelation 12:16-17 And the earth helped the woman, and the earth opened her mouth, and swallowed up the flood which the dragon cast out of his mouth. And the dragon was wroth with the woman, and went to make war with the remnant of her seed, which keep the commandments of God, and have the testimony of Jesus Christ.
This sums up that the Jews cannot escape the system of having both faith and works for their salvation. They need to keep the commandments of God and have the testimony of Jesus Christ in order to be saved.
