This constant assertion that every natural disaster is somehow an expression of God's wrath is bad theology. The Bible speaks to human suffering. Its called "time and chance" in Ecclesiastes 9:11. Many good and bad things occur to people regardless of whether they are good or evil. As Jesus explained, God lets it rain on both the just and the unjust (Matthew 5:45). In fact, in Luke 13:4-5 Christ refers to a specific contemporary tragedy ". . . Those eighteen on whom the tower of Siloam fell and killed them, do you think that they were worse sinners than all other men who dwelt in Jerusalem? I tell you, no; but unless you repent you will all likewise perish" (Luke 13:4-5).
The lesson of every natural disaster and human tragedy is not that the other guy sinned (he did... and so did you), its that life is short. The end will come without notice, like a "thief in the night". Remember, no one gets off this planet alive, so you best be worried more about your treasures in heaven than your 401(k).
Luke 21:34 "Be careful, or your hearts will be weighed down with dissipation, drunkenness and the anxieties of life, and that day will close on you unexpectedly like a trap"
