I have been having an interesting discussion with Pastor Corey McLaughlin on the subject of whether angels and demons are immortal. My view is that God alone is immortal (based on 1 Timothy 6:16).
But Pastor Corey argues that Revelation 20:10 implies that at least some angelic/demonic beings are immortal.
Catch up with the discussion by going to my latest post on the Afterlife website:
