I am not sure what you mean by “the second death which is, in fact, death”. Do you mean, gone obliterated not here anymore kind of death? Revelation 2 0 clearly states what that second death is. The cast in the lake of fire (the second death) are not obliterated from existence.
Yeah...The churches are not really literal lamp stands and the second death is not a literal lake of fire. We’re talking g Revelation here. :-)
I’ve been discussing/studying this for about four years now in person and on the web. I’m more steadfast in this belief than ever.
