Why Even Have A Resurrection At All?
Why do we stand before God like that?
Because according to the Bible we should fear Him that can destroy both Body and Soul in Hell.
You need a body a soul to be destroyed in that form.
The Wicked will enter into Hell in bodily form the whole body will be cast into Hell and you can't have that without a resurrection.
Real live people not just spirits will enter into Hell in bodily form so they have to be resurrected first be as they were in life and then be Judged for their deeds and then will go to hell.
That is Hell.

Job 34:14-15,
14 If he set his heart upon man, if he gather unto himself his spirit and his breath; All flesh shall perish together, and man shall turn again unto dust.

Thats what shall happen.
Ashes to Ashes dust to dust.
Like in these verses.
