I thought of making a list of things that still must come to pass that would make 70AD impossible, but I was too lazy. I usually do this at 12am-4am and am always in a hurry to get to bed. If you say Revelation was written in 90-94 AD 20 years past 70 AD, they just say John was writing about what happened in the past while he was locked up on Patmos. The Book plainly states it must come to pass in the future. John wrote “Blessed is he that hears the word of this prophesy. How can a prophesy do any good for the hearer if it’s 20 years old?
That is why preterists insist Rev. was penned prior to 70 AD.
