If there are so many other worlds inhabited by the children of God throughout the Universe, why were we here on Earth so lucky to host the Only Begotten of the Father? Well, the way I learned it was that the inhabitants of Earth were the very worst of everyone everywhere - the only people bad enough to kill the Son of God - and therefore needed Jesus the most.
First off let me say that whoever came up with this idea was an ass and Joseph Smith was a bigger ass for endorsing it. Why would our spirit brothers and sisters be any different than us when they have the same spiritual parentage, were exposed to the same ideas and learning processes in the Pre-Existence, fought in the same War in Heaven over the same issues, have to undergo the same "test" of faith and have the exact same potential to become like God? Do they have better access to angel messengers? Does Satan have less influence on them (because he was cast down to Earth and not Outer Darkness or Outer Space)? And if everyone is saved only through Jesus doesn't that mean that every single spirit child of God needs Jesus to exactly the same degree, or do people who don't swear and always tell their moms they love them only kind of need Jesus a little bit? The way I heard it growing up, even the amazing Joseph Smith was in dire need of the Atonement the same as all the other prophets.
Why do we sit through lessons on this stuff and humbly absorb it? Why don't we speak out against this drivel? Are we really so enamored with guilt that we can't shut this kind of shit down?
