What lesson is there in God zapping people out of existence?
In your discussion with PJTS on the OT stories you wrote
Sure, God could have zapped evil men out of existance... as far as I understand, but where's the lesson in that?
Offhand, I'd say it's in the same place as the lesson as eternal punishment in hell.
Why is eternal punishment acceptable and obliteration not acceptable?
