Verse 4 begins the book and you will notice that it begins in a typical first century Greco-Roman letter format. The author of the letter (not of the Revelation, which is from Jesus Christ) is John. The letter is written to the seven churches that are in Asia. Recall what we learned from the preface of the book of Revelation. The book is written in symbols. Therefore, we must read the book as written in signs and symbols unless something in the text demands a literal interpretation.
