It gets confusing, doesn’t it?
It helps to keep in mind something Stephen Gaskin said, that “We’re all telepathic.” Humanity is divided but not fully separated– each of us generally conscious only of a small part of all the mental/physical/emotional/spiritual processes we’re interacting with.
You might think of “God” as the totality which contains all that, its coherent spiritual form.
God is not this concept, or any other “concept of God.” But the concept may serve as a pointer to the God who exists, who lives inside each life.
If you could truly see your own soul, that’s what you’d find. The Bible calls this “the image of God,” but it is also the breath God gave Adam; it’s the only Life available that could have made us truly living beings.
Should you “believe” all this? It happens to be true.
