What was the Holocaust, a pick nick for the Jews? Wake up.
The Tribulation does not come upon the Jews only...
Mat 24:22 And except those days should be shortened, there should no flesh be saved: but for the elect's sake those days shall be shortened.
Carefully note, this does not say Jewish flesh, it says ALL flesh. There were Jews in Corinth, did they see the Great Tribulation?
Rev 3:7 And to the angel of the church in Philadelphia write; These things saith he that is holy, he that is true, he that hath the key of David, he that openeth, and no man shutteth; and shutteth, and no man openeth;
Rev 3:10 Because thou hast kept the word of my patience, I also will keep thee from the hour of temptation, which shall come upon all the world, to try them that dwell upon the earth.
The NKJV has...
Rev 3:10 Because you have kept My command to persevere, I also will keep you from the hour of trial which shall come upon the whole world, to test those who dwell on the earth.
The Diaglott has...
Rev 3:10 because thou hast kept the word of the patience of me, also I thee will keep from the hour of the trial of that being about to come on the habitable whole, to try those dwelling on the earth.
This is not going to be localized in and around Jerusalem, it comes upon the WHOLE WORLD. What happened in 70AD was not the GREAT TRIBULATION.
