The book of Revelation is always a big draw in church Sunday school classes and Bible studies, primarily because of the alluring prospect of being able to read Revelation in one hand the the newspaper in the other, assigning current events and political figures to the mysterious descriptions in John’s revelation.
One recurring theme in Revelation is the distinction between what is false and what is true. There are true and false disciples. There are true and false churches. There are true and false witnesses, true and false gospels, and true and false messiahs.
