In the eyes of believers, can God ever do anything wrong?

I don’t mean to be sacrilegious, but I’ve been rather amazed by the comments of some of the Christians who survived the Joplin tornado. I have seen people who have lost literally everything but their life, lost their home, their car, their place of work, their livelihood, their entiure city, their child, their pets… And they say “Thank God for sparing my life.” I can follow that. But how can God get the praise for leaving them alive, yet be completely innocent of inflicting all those losses on them?
