Jah-Jireh? Where's the Christianity in that name?
Sounds like some kind of strange blend of Judaism and Rastafarianism.
My 50 years long ultra loyal JW mother has even said that the name "Kingdom Hall of Jehovah's Witnesses" sounds like some kind of quasi Jewish sect rather than a real Christian religion.
Why don't JW's just rip the Christian Greek Scriptures out of their new grey NWT's and be done with it? After all, in JW doctrine, Jesus is redundant. He's just a step above one of the arch-angels. You can't talk to him or pray to him, and he serves no practical function whatsoever in JW theology. He was made King in 1914 - although nobody realised this except a few thousand Bible Students - then he retired in 1919 and handed everything over to the FDS (Governing Body), who you must blindly obey and remain loyal to in order to get saved.
