I do not understand all the comments as I believe Perry was just sharing his views on how the WBTS misleads its readers regarding this topic.
And, yes, the NWT rendering is pushing a doctrine. Most translations have PERISH but the word can mean DESTROY. It depends on the context.
But regardless the word chosen, the question is: from what does Jesus save. Well, there is not one answer. Jesus saved the Jews from the curse of the Law. Jesus saved the Gentiles from being lost and have no hope on eternal life. It has nothing to do with Armageddon, which is about a war with Kings and Armies.
To show in your daily life (acts and mind) you have faith in Jesus (name, person, position etc) means you hope to be judged positively after you died (judgment is with Jesus) and be granted the promised eternal life.
What happens to those who do not receive a positive judgment is another topic.
It all is about faith. If one does not believe or have faith, then whatever one writes about the bible makes no sense to that person.
