The Watchtower uses two scriptures from Isaiah as proof of people living forever on paradise earth.
Isaiah 65:17-25 actually does not say people will live forever, in fact the opposite, it says man will fulfill his days and die.
“For here I am creating new heavens and a new earth ; and the former things will not be called to mind , neither will they come up into the heart. 18 But exult, YOU people, and be joyful forever in what I am creating. For here I am creating Jerusalem a cause for joyfulness and her people a cause for exultation. 19 And I will be joyful in Jerusalem and exult in my people; and no more will there be heard in her the sound of weeping or the sound of a plaintive cry.” 20 “No more will there come to be a suckling a few days old from that place, neither an old man that does not fulfill his days; for one will die as a mere boy, although a hundred years of age ; and as for the sinner, although a hundred years of age he will have evil called down upon him
How about Isa 25:8. Was this understood by Jews or Christians that death would cease?
(Isaiah 25:8) . . .He will actually swallow up death forever, and the Sovereign Lord Jehovah will certainly wipe the tears from all faces. And the reproach of his people he will take away from all the earth, for Jehovah himself has spoken [it].
