Maybe this isn't the right place for this, if not, my apologies.

Why is it that we are told to thank God for our blessings, but we can't blame Him for the bad things in our life? If he is responsible for the good, does that not go to say that he is then responsible for the lack of good, or bad?

It comes up quite often, people say "but look what God has blessed you with!" And then I counter "well look what he has stuck me with" and I am told, it doesn't work that way, I have to be responsible for my own misfortunes, he didn't give them to me. Yet, He gets credit for the good? I don't understand.
