Do you know why American money is so successful?
Because it has written on it, “In G‑d We Trust.”
Not just “Believe.”
“Trust.”

Furthermore, the money even tells you its purpose:
Upon it is written, “E Pluribus Unum.”
The purpose of all your money dealings is to bring the plurality of this world to a Oneness.

And if that is truly your purpose, then you will rely on the One Creator to provide your needs.
