All of us came from God in Heaven where we were all part of the great energy which is the source of all living things in the universe. That energy is Him, eternally living in Heaven. But do not take Heaven as literal. It is not a place that most humans conceive. It is simply an existence. That’s it. Let there be no more description to it because the more we will be confused.
It is like God, living everywhere in the air, which penetrates and gives life to all that we see. Imagine without the clouds, sun, moon, planets, and stars. And there is only air which we cannot see with our physical eyes. That air is God.
