It isn’t really about knowing if there’s one God, ten gods, or no God.
It’s about knowing who you are, and want to be, in the midst of not knowing.
What do you believe; when will that be enough for you; where do you find your faith; how will you bring that to the world?
The why will be evident in the way you choose to live, each and every day.
You do not know all things, and never will. But you can know what is in your heart of hearts, and the truth that lives there, for you.
