‘In the final chapters of John’s vision, we might expect to discover that the sinners, who clearly do not escape the apocalyptic judgment described in 18:1–20:15,59 are either in the lake of fire or have now been annihilated by it. But instead, we actually find them outside the city (Rev 22:15). Furthermore, this “exclusion” is one that must be read in the light of the fact that there is still a mission to the nations (Rev 21:24; 22:2). John’s vision reveals that because sin has no future in God’s world, the impure may not enter the city (Rev 21:27). Yet this provides no ammunition for those who want to preach the “final” judgment of hellfire and damnation as “On no day will [the] gates [of the New Jerusalem] ever be shut” (Rev 21:25). Against the openness of God, the evil that would annihilate God’s creation, close down history and shut the world off from its Creator, does not have a hope in hell’. – Bradley Jersak, Her Gates Will Never Be Shut: Hell, Hope, and the New Jerusalem (Eugene: Wipf and Stock, 2009), 210.
This looks like a really great book on a topic that needs more friendly discussion.
Looked at from this perspective, this seems almost within the historic premillennial position. Note “historic”.
