Many think that the book of Revelation contains God's last inspired words to us. It doesn't. As wonderful as the New Jerusalem is (as described in Revelation chapter 21, descending to the new earth
from heaven), there are imperfections sewn in. What? Imperfections in the New Jerusalem? Then when does perfection finally come? When does God become all in all? The latest and greatest revelations, and the furthest look into the future, come via the pen of our apostle Paul. It is Paul, not John, who unfolds the last secrets sent by God to the human race.
