It is best to know what the bible says as an overview ( especially the new testament) before getting to excited about bible translations and which is the best because they all have some dogmatic slant to each of them.
The overview of the new testament is simply the disciples realizing Jesus is the promised Messiah talked about in the old testament and when he came back from the dead he was Jehovah in the flesh or “the angel of the lord “from the old testament. Then Paul basically creates the first century church and gods people become the body of Christ and not the Jewish people. Revelations, lots of weird stuff happens. The end.
I have never really saw much point fighting over indefinite articles and isolating single verses if you don’t really understand the reader digest version first.
I often find JWs seem to me are more interested in a weird way in disproving the bible.
