1.Jehovah`s Witnesses base their Bible on Christendoms determination of what books of Scripture were to become what is known as the Bible today,going back to the third century AD.
There were many ,many other books of Scripture in existence at that time that these men decided in their own imperfect wisdom not to include them .
Where it suited them the JW / GB would use the research of Christendoms learned men who compiled Bible Dictionary`s and Bible Concordances.
2.By far the vast majority of Jehovah`s Witnesses today are off-shoots of many of Christendom`s religions from whom they poached members from and then gave birth to their own offspring to grow in numbers.
With all of there self praise of witnessing in all of the earth ,it is mainly wholly contained in lands where Christendom has established the major religion of that land and JW`s have poached the most vulnerable people of that time.
3.How many thousands of people have they converted in Bangladesh ? Pakistan ? China ? India ? Muslim Country`s ? Etc,Etc.
Any Non Christian Nation ?
Oh they might be able to show a token two or three here and their but you can bet your bottom dollar they were affiliated with a Christian Church beforehand.
Jehovah`s Witnesses are not unique ? in any way shape or form they are just another sect of Christendom.
