Hi Iti
after death, a person has no consciousness anymore, so it would be hard to accept God after you die. That is why the bible says Eccl 9:10
All that your hand finds to do, do with your very power, for there is no work nor devising nor knowledge nor wisdom in She′ol, the place to which you are going
However, we believe that upon death, all sins are forgiven Romans 6:7
For he who has died has been acquitted from [his] sin
Therefore, God has no reason to punish anyone who has died because they are no longer viewed as a sinner. So their hope lies in the future resurrection....God will bring all who have died back to life, he will bring them out of the grave/hell and give them an opportunity to live again
Revelation 20:13, 14, KJ:
The sea gave up the dead which were in it; and death and hell* delivered up the dead which were in them: and they were judged every man according to their works. And death and hell were cast into the lake of fire.
So death itself will be abolished because God will make everlasting life possible.
