This quote is from the above text - said in a context where God was talking to Angels who were bad-mouthing men for having failed to obey God. God reprimanded them. I find it relevant to us who understand that it is all in the mind.
quote: Now Satan hath no power whatsoever, for he hath only what he maketh to germinate in the mind; and he cannot grasp firmly, and he cannot perform anything, and he cannot beat, and he cannot drag, and he cannot seize, and he cannot fight; he can only make thoughts to germinate silently in the mind. And him who is caught by the evil mind he prepareth for destruction; and if [a man] hath conquered the evil mind he findeth grace and hath a reward which is everlasting
