‘scholar’:
The outbreak of the Great War, a fact of modern history which marked the end of the 'Gentile Times' and inaugurated God's Kingdom along with the fulfilment of the Sign of the Parousia confirm the Bible as God's written Word and can properly be termed as 'cast in stone' as a venerable witness.
Except the ‘outbreak of the Great War’ was before October of 1914. But because something significant happened in that year, JWs quietly ignore that fact. 😂 (On top of the fact that the Adventist numerology is nonsense, on top of the fact that Jerusalem was definitely destroyed in 587 BCE, not 607.)
But even if the war had begun in October, it would not be evidence of anything beyond a coincidence, especially given the literally dozens of years suggested by various Adventist groups (including Russell’s group) in the 19th and early 20th centuries for ‘something’ to happen.
And of course JWs also ignore the fact that in the Bible, Jesus’ parousia explicitly follows the great tribulation. JWs don’t really care what the Bible actually says when it disagrees with their nutty doctrines.
