It is a common belief among Mormons that one of the reasons we come to earth is to be tested through trials. Supposedly, these trials teach us how to be sad, angry, grief-stricken, jealous, etc in order for us to know happiness, peace, joy, love, etc. Doing so will help us become more like God.
So, why is it then that not everyone lives long enough to experience these trials or live lives plagued by disabilities hat prevent them from learning these. If they are for our eternal benefit, why do some people get to bypass them and go straight to salvation (D&C 137:10)?
Is it possible that some people learn so much in the pre-mortal realm that the only reason they come to earth is to gain a body; that coming to earth would teach them nothing further?
Is learning such things just not as important to exaltation as we think
