So if we live in a telestial kingdom now, is it not because this is the highest kingdom to which we have ever belonged?  If we had achieved a higher before, depending on how high, would we not shake off this kingdom faster as did Joseph Smith?  Joseph lived a celestial law in an inferior kingdom to which he was sent to teach us until he was released from his condescension. Christ lived the law perfectly from birth.

Do we belong to this low place where we share space with devils because we don't know what we should be doing?  If the devil keeps us occupied with trivial pursuits, even thinking we do noble and great things, then we continue to languish from eternity to eternity in a fallen kingdom.1

We talk about the millennium as a terrestrial glory, but no being that doesn't quality for terrestrial glory now can live there, thus we telestial beings reside in darkness forever (to come forth in a later resurrection) until we decide to rise up.  We cannot assume we can abide a terrestrial glory when the millennium comes if we cannot and do not abide in the presence of the Savior now. When he comes, we judge ourselves, our minds burning and collapse with weeping and wailing at what might have been; we will realize we don't belong there and we shrink back into the kingdom we belong, to come forth later and have our experiences speak like a revelation to our minds saying, "Of that I will not partake." and "Of that I must seek and find," for as Joseph said, "there is never a time when the spirit is too old to approach God."2

Keep in mind that so far, we've only been discussing a residence in the telestial kingdom and the hope of a terrestrial glory.  After we are able to, and do abide the presence of the Lord3, we must be proven in that kingdom until we are able to enter into the rest of the Lord, to have a more sure word of promise, to hear the words of the Father say "ye shall have eternal life."4  Then are we able to dwell in everlasting burnings with the Father and the seraphim.5

We have no reason to be prideful.  We only have reason to be humble and view ourselves as less than the dust of the earth.
