D&C 29
And the righteous shall be gathered on my right hand unto eternal life; and the wicked on my left hand will I be ashamed to own before the Father;
28 Wherefore I will say unto them—Depart from me, ye cursed, into everlasting fire, prepared for the devil and his angels.
29 And now, behold, I say unto you, never at any time have I declared from mine own mouth that they should return, for where I am they cannot come, for they have no power.
30 But remember that all my judgments are not given unto men; and as the words have gone forth out of my mouth even so shall they be fulfilled, that the first shall be last, and that the last shall be first in

32 First spiritual, secondly temporal, which is the beginning of my work; and again, first temporal, and secondly spiritual, which is the last of my work
Creation is first spiritual, then temporal. Easy enough. But what is the inverse part at the last mean? First resurrection, then the sanctification of the soul? First the millennium and then the celestial earth?
