Is the Father the Spirit Himself, who speaks the Word? If he is not the spirit, what is the father then?
The Father is a Spirit (John 4:23-24); and there is one Spirit (Ephesians 4:4).
The Holy Ghost also is the Spirit (John 7:39).
But the Holy Ghost proceeds from the Father (John 15:26); so they are distinct from one another.
I explain this by showing forth that The Father is the Spirit who dwelt in Jesus Christ (John 14:7-11).
So, Jesus released His Spirit back to the Father (who dwells in eternity), in Luke 23:46.
So, in eternity, the Father exists side-by-side with the Father (the Holy Ghost)...John 1:1.
The Holy Ghost is the Father; but He is distinct from the Father in that He has lived a human life and therefore He understands humanity experientially (again, see Luke 23:46).
