Smyrna
In Revelation 1:11, 2:8, this signifies the church of people who led good lives from good, but hold false doctrines. (Apocalypse Revealed 91)
Smyrna signifies people in the church who wish to understand the Word but currently do not, and so have little knowledge of truth and good but wish to learn. (Apocalypse Explained 112)
