Christians:do you still believe that disease is a sign of the wrath of God?

I have know many Christians who say things like that... Pretty much any thing that happens to someone who is bad is the wrath of God... But they never seem to question the bad things that happen to good people, or the good things that happen to bad people. I guess that is where they get the BS "God works in mysterious ways"... I don't know about you but to me an all powerful being has no need for acting mysteriously and in fact would be more interested in being very direct with his creations in order to teach in an open and understanding way... there would be no mystery.
