"In life, the sandpaper of circumstances often smooths our crustiness and patiently polishes our rough edges. There is nothing pleasant about it, however. And the Lord will go to great lengths in order to teach us a particular lesson and to help us to overcome a particular weakness, especially if there is no other way. In such circumstances, it is quite useless for us mortals to try to do our own sums when it comes to suffering. We can't make it all add up because clearly we do not have all the numbers. Furthermore, none of us knows much about the algebra of affliction."
—Neal A. Maxwell, Notwithstanding My Weakness
