Hold on to whatever evidence you have of the Holocaust because there are organizations out to question, deny, and delete the existence of anything called "The Holocaust."
Unfortunately, although the horrors of Nazi extermination camps are beyond belief, the Bible warns us that this WILL happen again and it will be worse. Jeremiah calls it "Jacob's Trouble" (Jer 30:7). Daniel describes this soon-coming day like this:
there shall be a time of trouble, such as never was since there was a nation even to that same time (Dan 12:1).
According to the Book of Revelation and other biblical prophecies, at some point in the not-too-distant future (I think it will be a few decades from now - probably sometime in the last half of this century), the whole world will turn against Israel and will kill two-thirds of what's left of the Jews in Israel. (The world is already showing this turn against the Jews.)
One-third of the Jews in Israel, those who have accepted Jesus as their Messiah, will escape as Daniel goes on to say
at that time thy people shall be delivered, every one that shall be found written in the book (id).
Jesus is coming soon to take His own out of here before all this comes crashing down. As the Bible says, NOW is the time for salvation. Everyone, including the Jews need to come to Jesus NOW to be spared from this truly frightening and terrible day that is also coming soon.
Thanks, Papa. Reminds me of the old Chinese curse, may you live in interesting times.
