God..

.. is a belief to enforce humility among other things.. It is good to feel that there is someone you are powerless against. And the presence of that force is very evident in life... whatever it may be called.

The point then, is not to win favour or appease this Force. But to accept and revere the Force's presence. And be aware of your powerlessness. And certain "rituals" which at face value may seem pointless, help reinforce this reverence. And such an acceptance that you cannot control everything provides tremendous mental strength.
