65:18 I create Jerusalem. This is the New Jerusalem (Revelation 21:2), the holy city, specially created and prepared by Christ (John 14:3) to last eternally.

65:20 an hundred years old. The prophecy intermingles here a description of the eternal state with that which foreshadows it—namely, the great millennial kingdom of Christ (Revelation 20:6). During the coming thousand-year reign of Christ on this present earth, antediluvian conditions will be largely restored, and some people will live perhaps the full thousand years. However, as this verse reveals, there will still be sin and death present, so it cannot be the new earth. On the new earth, there will be no sin and death (Revelation 21:4). These truths are not contradictory but complementary, the one being a type of the other. The millennial and antediluvian ages are similar, whereas the new earth represents restoration of paradise, before sin entered the world.

65:25 the lion shall eat straw. There will be herbivores in the millennial period, as well as in the new earth, if animals are present there (a question which is left unanswered in Scripture). All carnivorous animals will revert to their Edenic state, when they were herbivores (Genesis 1:30).

65:25 not hurt nor destroy. This future state of the animal kingdom is evidently presented as the ideal state. This fact can only mean that there was no struggle for existence and survival of the fittest in the animal world as originally created. The evolutionary scenario, postulating a billion years of animal suffering and death before man evolved, is thus utterly false and even blasphemous, charging God with deliberately creating such a monstrous system as His means of producing men and women. Note also Isaiah 11:6-9.
