The Holy Spirit is the power, the life-force of all creation who inspires the Word and then after the Word goes forth, manifests the Word.
The Holy Spirit inspired the prophets to speak about the incarnation of the Word.
The Holy Spirit begot Christ Jesus through Mary.
We are born of the Holy Spirit as New Spirit beings by faith in the Word which He inspired and manifested In Christ Jesus.
So, the Father of all life, both physical and spiritual, is the Holy Spirit.
Because He is Spirit, He exists primarily in the Spirit Realm, which is Heaven. This is why Jesus instructed us to refer to the Holy Spirit Father as our Heavenly Father.
