SPIRIT
God is not separate from his spirit. God is an invisible, unchanging spirit. God and his spirit are one and the same thing — not two different entities as some religions teach.
God is not separate from his word. God is where his word is. God, his spoken word and his spirit are one and the same thing.
When God says he pours out his spirit, he means he is pouring out himself (e.g. his name, his character, his laws, his love, his mercy, etc.) through his spoken word.
