Abraham 4

In modern revelation, we learn that the earth will be celestial sphere for the righteous.  Enoch also actually heard the voice of the earth.  The earth was also baptized.  Obviously, there is a similar plan for the earth.  We learn through Abraham that during the creation -

"...the Gods watched those things which they had ordered until they obeyed."   (Abraham 4:18)

Even -

"...the Gods pronounced the dry land, Earth; and the gathering together of the waters, pronounced they, Great Waters; and the Gods saw that they were obeyed."  (Abraham 4:10)

Obviously, the earth was obedient.  Thus qualified for to be a celestial sphere.

In my mind then, there must be other spheres that were not fully obedient and thus terrestrial and telestial spheres.
