His coming into this diseased world means that, as Gandalf told Sam, “everything sad is going to come untrue.” (Rev. 21.3-4)

3 And I heard a loud voice from the throne saying, “Behold, the dwelling place of God is with man. He will dwell with them, and they will be his people, and God himself will be with them as their God. 4 He will wipe away every tear from their eyes, and death shall be no more, neither shall there be mourning, nor crying, nor pain anymore, for the former things have passed away.” (Rev. 21:3-4)
