Chapters, verses, and punctuation questionable.

The Revelation of John can best be understood as how “The Day” of Our God’s “Wrath” systematically unfolds as one layer of evil is removed by another, and Earth’s citizens are encouraged to “flee Babylon” until Our Lord removes the last evil. The complete unfolding will take years, not days or months, and the faithful will be used to help the lost enter our Lord’s fold.
