Beginning from the first chapter, each chapter of the Word of Revelation has a theme, and when unfolded they all connect with each other to the very last chapter. Just as in Romans, where chapter 1 is introduction, chapter 2 is God’s Word to the Jews, and chapter 3 is His Word to the Gentiles, the Book of Revelation also proceeds with a theme for each chapter.
The reason why I am explaining Revelation based on the entire Word is because too many people have discussed Revelation with all kinds of hypotheses, and if you read Revelation through the focus of these assumptions, you will not escape from making serious mistakes.
