[In response to covenant/amillennial theology, Blaising and Bock write:] “Rather than talking about an earthly, carnal kingdom, as the original language of the human prophet suggests, the “unconscious symbol” is the new heavens and new earth as the New Testament indicates by its emphasis on this theme and its exclusion of discussion about the land. One can raise the question that if language says one thing in terms of intention but really means something else, then is this not still a type of allegory” (emphasis mine).
