Justice :)
Don't you see that criminals like "Hitler" died without being judged and punished for the millions of lives he caused to die ?
To think that there is no resurrection and another life after death where every one will be held accountable for all hi\her choices is very unjust.
If there is no resurrection where good people will be rewarded for their righteousness and their patience , and the evil people will be punished for the evil they did, then there is no reason for any person to do good or be good, since the evil ones do what they want and just enjoy it all then kill themselves and end it like that.
Then, is it difficult ? that dead people who turned into dust be resurrected again ?
No, it is not difficult for the One who started it all from nothing and brought everything into life and then took the life from everyone. He can easily bring life back again to these decayed bodies.
Have a look on this belief in resurrection , watch episode 19
