A fun thing to consider is that if Jehovah could create a new body for you and dump your memories into it AFTER you died, he could as easily do so BEFORE you died. Then there'd be two of you. Or from your perspective, one you and one fake copy of you.If we now said we were going to kill you and let the copy live, would you say, "OK, that sounds reasonable"?
So why is it reasonable if we change the order of events?
Again, allow me to respond as a JW would:
Well, in a cheap science fiction novel, the above scenario could happen. But the Bible tells us that God is loving, just, etc. It would be unloving and unjust to make a copy first, kill one, and let the other live. Since God is the only one with the power to do this and we are assured he is perfectly loving & just, the scenario presented, while theoretically possible, would never ever occur.
(I'm just trying to see how far the argument might go if raised with a semi-intelligent JW)
