Don't know - don't like to think about it. But how about this... how could you POSSIBLY have the same type of personality if you had no drives for food, sex, herding, parenting, sleep etc. Personality is a tool used in pack or herd animals in order to fit inside an existing social structure - what possible personality would an eternal being have?
In any event, whether death is the end or not, Jehovah is CERTAINLY not involved in any of it. Jehovah is just a Hebrew tribal myth that should've died out with Marduk, Tiamat, Baalam and Asherah.
