Please note that there are alot of videos and articles online saying that the world was supposed to end on 23rd September 2017. The Bible is clear and never says that the world will end on this date. It is clear that these are signs only and point to the time in which we live.
There are also articles online rebutting this sign which say that the stars aligned this way many times in the past. This is not true. Some of the dates given where this has happened in the past do indeed have 1 or 2 elements in order, but never before has the stars aligned exactly as in revelation.
