I thought it might be helpful to put together an 'End-Times Overview' chart of all the key events prophesied in the book of Revelation. In general, the book of Revelation maintains a sequential order of the prophesied visions concerning Daniel's 70th week. The exception is when the Apostle John is told to 'prophesy again' (Rev 10:11). At that point, we are graciously and repeatedly provided with many more new details of the last 3 1/2 years of Daniel's 70th week... and even beyond.
I believe that one of the purposes of prophecy is to prepare God's people for extremely difficult times.
Finally, don't be surprised if we are all a little confused on the exact details of the Second Coming. After all, John the Baptist, one of the most righteous men in the history of the world, was very confused with the details of the First Coming. It seems God loves mysteries and is pleased when we struggle with His Word. It forces us to rely more upon Him. There are at least three commands we are given that produce a lot of tension when considering end-times: First, the one who endures to the end will be saved. It begs the question, the end of what? Second, we are to watch for the specific prophesied signs of His coming so that we are not caught off guard. Third, Jesus will come at an hour we do not expect. So, no one is going to figure out, to the day, when He will return. We are all going to be surprised in one way or another!
