If something is said to cause something else, then it is by definition separate from that which it has caused, is it not?

How can you have the chain of cause and effect without expressing the concept of separation? If God causes anything then God is separate.

And it must happen within time. What if God is larger than time and space themselves, existing beyond time, beyond space, and they are both simply observable phenomena that arise out of the unseen field of limitless possibility that is God, seen through the mechanism of our separated consiousness....? That mechanism being yours and mine...our busy little separated minds, observing, naming, and categorizing things...and debating about them here for a little space as if we knew!...like Shakespeare's fictional characters in his plays...strutting, fretting, and declaiming while their part lasts.

Then the play ends, and it was all seen to be a clever illusion. We're all actors, Amos.
