@Lost **** my notes say 2000 yrs. ***....
It is quite conceivable that the church age could span the life expectancy of our little solar system, approx 14 billion years as considered to be left on the clock. However, this makes no difference to us PERSONALLY as we have a life span of seventy years (if we are so blessed) to account for.
Peter's 2 letter is considered a much later work, where after 70 AD, the author seems to be pointing to thousands of years, 2 peter 3:8, rather than the earlier letters from Peter and Paul, pertaining to the last days of Israel in 70AD. The emphasis here is awaiting the "Lords Day " and the "new heavens and new earth" 2 Peter 3:13....it seems also to suggest that it's NOW a LITERAL cosmic event where the description of the physical elements are being destroyed like the physical flood, and could be just the natural way our solar system would burn out or be engulfed by a black hole. However, the New heavens New Earth, aka the Jerusalem above is already a spiritual reality since 70AD, to be finalized.....whenever ! Just sayin
Shalom my friend !
