YHWH = Jehovah
They make you aim your prayers at a specific God named Jehovah while they admit the original pronunciation is lost. People live and give their lives, shun family members for this name.
Isn't it better to just use the title God as opposed to using a personal name with extremely questionable accuracy? Even though their own literature admits the original pronunciation is lost they still put 'Jehovah' into their bible! Of all the things not to take a chance on, the personal name of God must be No: 1 IMHO.
When I meet people and I cant remember a persons name, I normally avoid using a name in the hopes I will remember or someone uses it. Once I'm certain then I will freely use it. GB makes an uncertain name the cornerstone of their organisation and forces their members to use it. Imagine at the second coming if the name turns out to be Yahweh or something else. How would an organization called 'Jehovah's Witnesses' explain using a name they were not even certain of for the God of the old testament and remain alive?
This is a case where people made a God and not a God people.
