Hebrews 9:27 And just as it is appointed for man to die once, and after that comes judgment,
That scripture clearly says man MUST die once. And if you combine that with
1 Cor 15:53 and 54 that pretty much say fleshly bodies are mortal and to live forever one must be reborn immortal in a non fleshly body, which goes along with Hebrews 9:27 saying that everybody must die once,
and finalized with Isaiah 28:18 that says those who proclaim they will never die, have invented their own convenant with death and it will NOT come to pass!
It seems to be universally clear that the scriptures teach mortal man WILL die, everybody will die one time.
I wonder what the JW response to those scriptures would be. Actually I know, "I'll get back to you."
