They Will Be No More As God Is A Consuming Fire!
God is very clear on this as in not even a coal left to warm yourself at nor fire to sit before and when God is done they will become as stubble the fire will burn them and none shall save them from the unquenchable fire and nobody is going to put it out either it will consume into dust like Satan will also be consumed into ashes from within.

Job 30:19
He hath cast me into the mire, and I am become like dust and ashes.

Ashes to ashes dust to dust.

Isaiah 47:14-15
Behold, they shall be as stubble; the fire shall burn them; they shall not deliver themselves from the power of the flame: there shall not be a coal to warm at, nor fire to sit before it. Thus shall they be unto thee with whom thou hast laboured , even thy merchants , from thy youth: they shall wander every one to his quarter; none shall save thee.

This is what God says.
This is God's word.
