One of the phrases I have grown to detest is "God's mysterious ways." This phrase tends to be invoked when you stump a Christian. It's not uncommon for them to become flummoxed and in desperation they blurt out that time-honored phrase.
Though few will ever admit it, what they are really saying is Shit Happens. In a backhanded way, they are admitting that things occur randomly. Of course, the REASON they can't admit the obvious is that it undermines their belief in an almighty, all knowing AND loving deity. If their God makes decisions based on whims, why worship him?
It brings us back to the gnawing question: Why does God supposedly answer some prayers, but not others? Why does he direct you to wear a certain outfit, but not warn you that you will be in a train accident later in the day? Why does he save a drunk who caused a ten car pile up, but not the young mother in car 3? Why does he supposedly protect some people during a tornado or hurricane, but not others? These questions are particularly pertinent when each of the survivors and victims were praying to be saved from harm's way.
Whether a person explains these results as "God's mysterious ways," karma, shit happens or blind luck, it all amounts to the same thing. People live and die and we often don't have a clue as to why.
