It is all about what comes from Spirit from God Himself and since it is only God Himself that existed before anything was created the very beginning of Jesus (before time) was only from God Himself and only by Spirit. The Son of Man was created and begotten only from Spirit and only from and by God Himself so He was entirely spirit since only spirit existed before all things were created. So He more than anyone is the Son of God. Then aeons later in our time and space in this created universe He was made again by being made flesh and again it was by God and by Spirit.
