Mary Baker Eddy in "Science and Health with Key to the Scriptures" thus defines the word "in" (p. 588): "A term obsolete in Science if used with reference to Spirit, or Deity." God is not in anything. Deity cannot be localized. Where could God, the one all-inclusive Being, who fills all space, be confined? How perfectly our Leader, Mary Baker Eddy, explains Deity's all-inclusiveness in "Unity of Good," where she writes (p. 3:)
"God is All-in-all. Hence He is in Himself only, in His own nature and character, and is perfect being, or consciousness. He is all the Life and Mind there is or can be. Within Himself is every embodiment of Life and Mind.
"If He is All, He can have no consciousness of anything unlike Himself; because, if He is omnipresent, there can be nothing outside of Himself."
