why do bad things happen to good people?

i just have to sit and wonder why? my dad is losing his job and will be losing his house soon, i mean with this economy it is no surpise, but why does it have to happen to the good people? Everyday i hear of a friends parent who is losing their job, or I'll hear that my good friends dad has cancer after her mom just got treated for breast cancer...this leads me to wonder do things just happen for a reason? does everything that happens, happens for a reason? i've never really been a believer of it, but lately i have been thinking it could be a possibility. I not a big believer in god, how could he allow this much pain to someone, how could he allow two very religious parents to get cancer? why not the drug dealer? or the man who killed someone? These questions all lead me to believe that if there is a god, he lets these things happen for a reason. To open our eyes to our life. maybe we complian about it wasting away, and we need a reason to make it worth something. maybe things happen to show you that what you have isnt what you want. maybe things happen to make you appreciate your life more. so why my dad is losing his job and house, im not sure what the meaning behind that is, but in time everything that happens, happens for a reason and in the end works out, and your life goes on.
