What does that prove other than we've "come out from among them", and are "separate", and "touch not the unclean thing" no more, and have been "received unto Myself"?
Certainly not consciousness in death, in which Scripture says "the dead know not anything".
You're co-mingling a prophecy which refers to the 1,260 year reign of "gentile" papal " tyranny against the "Israel of God" church who belong to Christ and are, thus, "Abraham's seed"...but that's another discussion.
We're not talking about the nature of time - the focus is the
nature of man and how time affects him.
Man is mortal, and for this time wears immortal clothes...
Then, time will find him - unless the Lord returns - lying naked, unclothed, without a body, resting in peace, dead and waiting for the resurrection...
Afterwhich there will be "time no more" when Jesus comes and calls him forth from sleep to Himself and he rises with an immortal, incorruptible body, and not a second sooner.
Once in a while I come across this teaching that all men preexisted before they were born. Let's ask Solomon if that's correct:
Ecclesiastes 4:2-3 KJV
[2] Wherefore I praised the dead which are already dead more than the living which are yet alive. (Why? Obviously, contextually, because the dead guy's through with life's misery - the living yet endure it)
[3] Yea, better is he than both they, which hath not yet been, who hath not seen the evil work that is done under the sun.
Now, if we've been around since Earth's foundations and not seen the evil controversy between Christ and Satan, our heads must have been firmly shoved way up our celestial badunkadunks.
