Revelation 8:12
Firstly, make no mistake: It can be argued that this is, in fact, the most important website on the Internet (you'll soon see why). Now, regarding the Book of Revelation, the bottom line is that you are not aware of what has already taken place. I will keep this very simple. Start at the 6 Questions website, then go from there:
https://www.6questions.org      »      Primer      »      TimeDiff      »      Revelation 8:12
So, first go to 6 Questions, and then go to the primer. Read the primer, and then go to TimeDiff. At TimeDiff, you will see Revelation 8:12 in all its glory. Have a great day.
