The depressing thing though is that witnesses living in the 21st century, have no idea whatsoever about all the past flip flops and alterations.
They are encouraged to just look at the situation now.
So what they see is revolutions in many countries, financial problems in leading world economies and their mother organisation telling them that this shows how we are at the end of the present system.
For many that is all they need ie reassurance that everything will work out very soon.
