So God needed His creation to say.....I AM!
But does He abide within a body?
I think not.
Don't "think."
Being conscious and alive is not separate from body.
Pulling scriptures out such as you have, why don't you search where "God" abides. Where the tabernacle of God truly is.
"I am." =
The very nature of God. The phrase “I AM THAT I AM” is meant to be understood metaphysically, it means God is BEING. BEING is that which is both the un-manifested (spirit) and that which is manifested (physical matter) at the same time. God is the sum total of both, the unborn infinite potential and the creation.
I'm not sure what kind of image you've created of what and who "God" is but it gives the false impression of the infinite, God cannot be represented by any form (things). Contrary to popular belief, God does not have a body separate from his creation. He is the sum total of it all.
