How on earth can you say that? What of the 24 elders first mentioned in Revelation 4:4, and the multitude of saints praying before God's throne in Revelation 5:8. These people are clearly already in Heaven. The saints mentioned are emblematic of all people who will have died and attained Heaven before the Last Day.
Please, do the italics thingy. I've been posting a lot. I'm guessing you are talking about people being in heaven?
Where does it say the 24 elders are human?
