A specific pattern of sun, moon, planets and stars was written down almost 2000 years ago. That pattern will occur over a two day period of September 23-24, 2017. It is the first timing verse in Revelation. It is very reasonable to conclude that the things that are spoken of in Revelation will either start or be underway on that date. If you wish to ignore this, that is on your head. The Watchman has sounded the trumpet.
We are indeed in the End Times -- have been since Pentecost. The Time of the Church is the Time of the End.
