Even though many individuals have the idea that a person cannot see the future, that kind of individual is ignorant of the structure of Bible Prophecy in the 70 Weeks of Daniel in chapter 9, and other very important points surrounding it.  There remains on the Prophetic Calendar a period of 2,520 days divided into two equal halves of 1,260 days each.  Jesus Christ warned that a person should pray always that he may be worthy to escape all these things that will come to pass and stand before the Son of Man.  Who is worthy?  Those individuals who have accepted Him as Savior have received the Holy Spirit and are now worthy.
