The depravity of man increases, in my opinion giving more credibility to prophecies seeming to point to Sept 2015. Stay alert. Seek Jesus.
However - Matthew 24:36-37 - Tells us nobody knows the day (i.e. Sept 13, 2015?), but just like Noah, believers can have assurance that that last day is very near. With Israel placed back in her land in one day (May 14, 1948; Isaiah 66:8 ) and Israel retaking the Temple Mount in 1967, there's good reason to believe we are at the very end of this age. Just as Noah knew it; we know it - the final day is near.
“36 But of that day and hour knoweth no man, no, not the angels of heaven, but my Father only.
37 But as the days of Noah were, so shall also the coming of the Son of man be."
