Are you sure there is even one?

Older religions believed in a multiplicity of gods, for example the Greeks and Romans. Monotheism probably started with the Zoroastrians. Christians say they are monotheistic but they worship the father, Son, and Holy Ghost and attempt to unify these into one god. Muslims are truly monotheistic as they only worship one god.

There is only one Creator but many lower gods. The creator only needs you to know IT and love IT. You do not have to worship IT. Only lower gods require worship and religious practices that give rules to follow for proper adoration of this god and how to follow it's rules. The Creator has no rules and requires no religion for IT resides within you, not in a building. 

By using the same logical reasoning in concluding that there is only one.

We are all of God children so we will be God after graduation from this life of suffering ach & pain ,sorrow And learn to accept God grace that was promise to them that ask sincerely. God Bless YOU.amen.
