Revelation

I have to speak on the last book of revelation coming August in training ministry.
I therefore read books on it.

Structure,symbolics,interpretations,applications are
4 main reading & exploring themes.

In terms of structure,linear cyclical and spiral are some of the familiar ones.

Symbolics,how to interpret the lion,dragon,women,beasts in the book ?

Preterist,historical,futuristic,ideological are also familiar interpetative schemes.

Coming out of the evil city,the Lord's sovereign control and perseverance amid trials and tribulations are some of the main applications.

Wow! How can I understand better when going into more details !?
