This article explores Jesus’ prophetic teachings in Mark 13 about the destruction of the temple, the end times, and the need for believers to remain faithful amidst trials and false prophets while trusting in God’s sovereign plan.
Other things to consider:
Who is the Oliver discourse speaking to? A Jewish or Gentle audience, or a combination?
Mark was written anonymously, with the designation “according to Mark” being titled in the 2nd century, CE. Thus it is not a first hand account.
Since the New Testament believers considered the return of Christ to be imminent, viewing the scripture as a prophecy for over two thousand years after the fact is very problematic, and a consideration that, like Revelation, must be considered as a retort concerning the treatment of Jews and Christians under Rome.
The author of the article makes a very valid point about being alarmed over wars and rumors of wars, etc. These things have always been around, as have men claiming to be the Messiah. It is nothing new.
