But What Did I Do?

I want to ask that question more and more. Let me explain what I am thinking. So many times I will have people say thanks. Of course we all could use a little more thanks. But I want to get the point where I am more and more dependant on God to the point where when someone says thanks, I can say "But what did I do?" By saying that, I would be giving the person who deserves the credit, the credit; That would be God!
