Sorry "tooldtocare" - we went a bit "off-piste" on the topic you started!
I don't doubt the initial statement of your last post - BUT, doesn't it say somewhere in our Bible that "God will not always strive with man forever"! I tend to be a bit of a pessimist and view the world and it's current state as becoming "darker" - i.e. more chaotic, wicked and in danger of "imploding" having ruined everything. So I reckon the time may come, when the Lord says "I have seen more than enough of this!" and will "call time" on us here on this globe - and before
we are in danger of spreading our wicked ways to any sentient life elsewhere in the universe. Why would the Lord permit us to infect others with our wickedness?! In other words, am expecting/hoping for the "Parousia" etc, - OK so that puts me in the "Pre-Trib" camp - somewhen in the future, to put an end to our folly! When the Lord "tires of it all" and considers that He has harvested sufficient of what is good and worth saving - then doesn't the Bible say something like - He will roll up his Creation as one would roll up a tent!? He will go on forever, but will our "civilisation"?
In any case, if "we" do go on further than I expect - then there is the almost inevitable effect that as our star - the Sun - grows much older and less bright, it will at some stage begin to expand, so the astrophysicists tell us, and engulf the nearer minor planets - putting an end to everything we are, as it all gets burnt up! ("if you can't stand the heat then get out of the kitchen" as they say - so if humanity still exists, then we will need to migrate elsewhere in the cosmos, to somewhere a bit more suitable for us, long before such a happening!)
Am thinking that we live life, under the Lord's over-arching authority, a bit like a pet dog allowed freedom for a while at the full length of a long extending lead. But somewhen, our "owner", if He thinks we may have transgressed too much (scavenging in the case of a pet dog!) - will haul us back in, towards Himself, to put an end to our "naughtiness"! Am of course, thinking of what Paul wrote "...you do not belong to yourselves, you were bought at a price..."
BTW - Lets have a little chuckle over comparing ages (re : your choice of a "username", suggesting you just might be approaching the 100s!
) - am just at the start of my 80s (but currently, such are the signs of wear/tear" that I may not reach my mid-80s) - Have you been given the grace to go on further?
You know what Solomon says in Ecclesiastes "Remember your Creator in the days of your youth, before the time of trouble comes, and the years draw near when you say 'I see no purpose to them' ".
Oh what a "cheery" note to end on!
