In Revelation 17:9-10 we read:
"This calls for a mind with wisdom: the seven heads are seven mountains on which the woman is seated; they are also seven kings, five of whom have fallen, one is, the other [the 7th]
has not yet come, and when he does come he must remain only a little while."
Okay, the 7th king will come sometime after the writing of Revelation and will remain "only a little while." Hitler and Nazis were in power twelve years; relatively speaking a very short time. Revelation 13:3 says one of the heads of the beast had a fatal wound which had been healed: "One of its heads seemed to have a mortal wound, but its mortal wound was healed, and the whole earth marveled as they followed the beast." It's interesting to note that Hitler died of a gunshot wound to his head.
Revelation 17:11 describes the beast itself as an 8th head:
"As for the beast that was and is not, it is an eighth but it belongs to the seven. . ." v.8 says:
"The beast that you saw was, and is not, and is about to rise from the bottomless pit. . ."
So we have a beast which "belongs to the seven" and will be fatally wounded and will rise again. This suggests that the final beast will somehow be in Hitler's image. Not a literal reincarnation necessarily; if Hitler were to be literally reincarnated no one would listen to or follow him. But the final beast will follow in the mold established by Hitler.
I'm reading a very good book called Plotting Hitler's Death: The Story of the German Resistance by Joachim Fest. On pg. 20 there's an interesting account of the mood that was present in Germany shortly after Hitler came to power:
"Wilhelm Hoegner, the future prime minister of Bavaria, recalled wandering through the streets of Munich feeling that all of a sudden they had become hostile and threatening. Helmuth von Molke's mother felt profoundly uprooted, as if she 'no longer belonged to the country.' Others have spoken of losing old friends, of an atmosphere of suspicion, of spying neighbors and the rapid disintegration of their social lives even as the alleged brotherhood of all Germans was being celebrated in delirious parades and pseudo religious services, mass swearing of oaths and vows under domes of light, addresses by the Fuhrer, nightly bonfires on hills and mountains, secular chants and hymns. All this fervor was fueled by the intense sensation that history was in the making."
Now let's look at some scriptures that that describe similarities between this and the reign of the Antichrist:
Hostile and threatening:
"And it was allowed to give breath to the image of the beast, so that the image of the beast might even speak and might cause those who would not worship the image of the beast to be slain."—Revelation 13:15
An atmosphere of suspicion:
"You will be delivered up even by parents and brothers and relatives and friends, and some of you they will put to death."—Luke 24:16
Brotherhood of all Germans:
"and the whole earth marveled as they followed the beast."—Revelation 13:3
Pseudo religious services: A lot of people may not be aware that Hitler actually tried to wipe out true Christianity in Germany and replace it with a National "Christian" religion called German Christians. Dietrich Bonhoeffer was one of the true Christians who resisted Hitler and it eventually cost him his life.
Swearing of oaths and vows:
"Then I saw another beast rising out of the earth. It had two horns like a lamb and it spoke like a dragon. It exercises all the authority of the first beast in its presence, and makes the earth and its inhabitants worship the first beast, whose mortal wound was healed."—Revelation 13:11-12
History in the making:
"and they worshiped the beast, saying, 'Who is like the beast, and who can fight against it?' "—Revelation 13:4
I'm sure there are plenty of other similarities between Hitler and the final beast. I might add them as I come across them.
