Of course I’ve thought about it! As far as your contention that “I think the end came in 70 AD” most scholars date the Johannine epsitles after 70 AD. And thankfully, the “last days” are awfully long owing to God’s grace and patience that all should receive the gift of eternal life.
Awfully long, but less than 100 years left? What gives you the sort of historical or spiritual perspective to judge that? Why not another 100,000 years? To believe that today's world is somehow new and shockingly different, and suddenly ready to fulfill all the prophecies, is to lack any sort of historical perspective and to indulge in a rather egotistical bout of navel-gazing.
We're not so different, and our world is not so different, from the world of the past 1,938 years, in terms of relation to Biblical prophecy.
