It is next to impossible to scientifically verify metaphysics with all the metaphysical beings and prophecy. While the book of Revelation with all the speculation it brings can sow division and paranoia, it can also bode of a better future and lessons from the past. Take for instance the well known article about the wild beast antichrist bearing the number 666.
This calls for wisdom. Let the person who has insight calculate the number of the beast, for it is the number of a man. That number is 666. - Revelation 13:8
King Solomon of Israel was the author of the book of Proverbs. He was renowned for his wisdom and never to be matched wealth. In it he wrote:
There are six things the LORD hates,
seven that are detestable to him:
haughty eyes,
a lying tongue,
hands that shed innocent blood,
a heart that devises wicked schemes,
feet that are quick to rush into evil,
a false witness who pours out lies
The similarity to history's villains and their movements are open to speculation as to who this could apply to, if not portending of one yet to come.
