Someone who trusts in G-d is happy when he has money because he can give charity and happy when he doesn't have money because he doesn't have to worry about protecting his wealth. His sense of security doesn’t come from money and his identity is not based on having or not having it. He views money as something that is passing through his hands at the moment and he only needs to make sure it gets to the places it's meant to go.
