Look at the Watchtower. In order to govern with the help of the Bible, they are forced to pervert what is written in it!Absolutely one thing can be said: only liars who pervert the Bible seek to rule with the it.
Cant really argue that.
The ancient Hebrews were set about to support "their' own select god, their god which they proclaimed was the highest and mightiest god over all others and he had chosen them as his earthly chosen ones.
They were therefore in need to create power and relevance, to create and support belief, respect and worship for themselves.
Not really that hard to understand when you really think about it.
The JWS proclaimed that Jehovah god has left the Hebrews (Jews) and went on to choose them as his earthly chosen people.
That's a story in itself with understanding reason, purpose and intent.
