One who trusts in H'shem understands that his money is a deposit to be used as needed to serve H'shem. If H'shem gives him wealth or takes it away, he does not change his happiness or trust as he knows that it is to his benefit whatever H'shem decides for him. He is always happy with his portion and never tries to take what is not his.
