God is Spirit? Alma 18 & 22

      "God is a great spirit" and "God created all things" are two concepts that go well together in the book of Alma.  Alma 18:26-29 says, "And then Ammon said: Believest thou that there is a Great Spirit?  And he said, Yea.  And Ammon said: This is God.  And Ammon said unto him again: Believest thou that this Great Spirit, who is God created all things which are in heaven and in the earth?  And he said: Yea, I believe that he created all things which are in the earth;..."  Alma 22:9-11 says, "And the king said: Is God that Great Spirit that brought our fathers out of the land of Jerusalem?  And Aaron said unto him: Yea, he is that Great Spirit, and he created all things both in heaven and in earth. Believest thou this?  And he said: Yea, I believe that the Great Spirit created all things, and I desire that ye should tell me concerning all these things, and I will believe thy words."
      If these Alma passages stated that God was confined to a physical body, it would be a problem.    Creating a physical body requires matter.  The matter in this physical body would need space to exist in.  It would also need time to exist in the space.  These passages state that God has created all things in the earth.  Matter, space and time are things that exist in the earth.  So, according to these passages, matter, space and time were created by God.
      Is it possible that God is subject to his creation?  Did he create himself?  If God was confined to a physical body, he could not have existed before time, space and matter were created.  Moroni 8:18 says, "For I know that God is not a partial God, neither a changeable being; but he is unchangeable from all eternity to all eternity."  The words from all eternity to all eternity mean from an infinite amount of time in the past to an infinite amount of time into the future.  God has always existed just the way that he is today.  He has never changed.  He existed before time began.  He is greater than matter, greater than space and greater than time.  He is not subject to them.  Matter, time and space are subject to him.  These are things he created.  These two passages say that God is a Spirit (not confined to a physical body).   So, the concepts of creating all things and God being a spirit, go well together.
