This probationary period is kind of the last test to see if we will keep our second estate and recieve exalation or whatever reward we are fit for. In the end, I think after eons of existence, we are ready to make a decision on where we want to be. The kingdoms of glory sound wonderful, each in their own light. I'm sure their will be absolute bliss and happiness in any kingdom you end up in, hence why Joseph said what he said about people would kill themselves if they saw how good it would be. However, eternal progression can only happen for those that make it to the celestial Kingdom as the necessary ordinances to enter it are earthly ordinances and must be done in the flesh, either in person or by proxy after one has died. When the Lords final judgement is handed down, this work will be done. (For our generation of people or round of existence) Those that have been exalted will then go on "from grace to grace and exaltation to exaltation" by creating their own worlds and spirit children. They will hold the "office" of Heavenly Father and Mother, and their first born son would have to be the savior for their children as it has been done in the past in other worlds or existence. (Satan was not lying in that regard) But the people that will inhabit these worlds will be OUR spirit children, not the children of Elohim. His children will have already lived and died and are living out their rewards. Elohim's glory would continue to grow as His children that were exalted would continue the work of the Gods in the propagation of our species, creating worlds and bringing to pass the immortality and eternal life of men, so they too can become Gods.
The plan of salvation is indeed beautiful, as designed and is in no need of MMP for it to work. Indeed, it would invalidate the purpose and promise of our Lords atonement, in promising no more death, because He conquered it for us. It seems silly to look to Buddhism for light and knowledge when we already have the established word of God all pointing to this life being our chance to prove ourselves.
