A person knows that he is in a rough spot when he really needs something and the two people most likely to help him are, say, Reuvein and Shimon. So he goes to Reuvein who tells him to speak to Shimon. Shimon will help him. Then he goes to Shimon who sends him to Reuvein for help.
At that moment he KNOWS that it is Hashem who must help him and Reuvein and Shimon with all of their good intentions are not the right addresses for salvation.
We call it "Bitachon".
