The Bible says " the wages of sin is death " Rom.6:23 , So death takes away the Adamic sin that humans inherited from Adam and Eves disobedience which resulted in imperfection for the rest of the human race.
So once you die, you are no longer a sinner or imperfect ,and once you are resurrected by God Jehovah /Christ Jesus ? You are without sin or imperfection.?
So you shouldn`t die again and if you do what for ?
There are a couple of accounts in the Bible of a resurrection taking place ,are they still with us today ? No.
Modern science in medicine has brought back many from the dead these past 50 or more years in hospitals ,have they died again ? yes ,why ?
Well to me the answer is obvious.
You draw your own conclusion .
