Did you think about that at all? John was speaking to his contemporaries in the first century, not directly to us. THEY were living in the last days; these words are no reason to believe we are. If so, the "last days" are awfully long. In reality, I think the end came in 70 AD.
Yes, but which "end"? Temporally speaking, it was the end of the old covenant system and the beginning for the new (Heb. 8:13). Jesus appeared at the end of the ages (aeon) (Heb. 9:26).
Christ will return one day to cast Satan and his followers in the lake of Fire, put an end to death and Hades, make our bodies like His, and wipe away every tear.
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.
Then the Marriage Supper of the Lamb in Heaven has come and gone...YOU missed it...
