Reading the Fourth Gospel ('of John') it is almost incomprehensible how mainstream Christians became dogmatically fixed on the idea that God the Father was a spirit, and not incarnate; given the multiple and clear references to Jesus stating that he and the Father are the same in form.
The Father, we are told, is incarnate, has a body - this isn't in doubt, but the question is what this state of incarnation means.
Part of the prevalent misunderstanding that The Father is spirit derives from the already-existing philosophical idea among Classical pre-Christian intellectuals that God 'must be' a discarnate spirit, because spirit was the highest form. They regarded bodies as matter, and matter as lower than spirit - more restricted, prone to corruption etc...
Another element is that the nature of purpose of incarnation is mis-stated by the word in-carn-ation itself, with its reference to the body - asif that was the most-important aspect of the definition.
But if we accept that the ultimate reality of creation is consciousness, and that God 'thinks' creation into manifestation and sustains it as such, and that it is by our thinking that we may come to be like God... then matters become clearer.
The facts of Jesus being incarnated (from his pre-mortal state as a discarnate spirit), and that he was resurrected into the same incarnate form as ourselves, ought to show us that incarnation is a higher form than spirit. But it is not the addition of 'matter' or 'solidity' that makes incarnation higher than spirit (matter/ solidity etc. are merely consequences of incarnation) - rather it is the mode of consciousness of an incarnate that is higher than a spirit.
Incarnation is a necessary step towards divine consciousness - towards the form of consciousness of the Father and the Son.
We began as children of God in the form of pre-mortal spirits, immersed-in the divine consciousness. As such we were all happy and good; but in the incomplete, immature ways that a young child is happy and good - by virtue of our environment, not from-our-selves.
Spirit consciousness lacks full agency - a spirit is, to a considerable extent, immersed-in the consciousness of other spirits - the individual is not divided clearly from other spirits, or from God the Father. Therefore, our pre-mortal spirits were passively immersed-in the divine consciousness - we lacked 'free will'.
To fulfil a destiny of becoming fully Sons of God, of the same kind as Jesus became; entails that our consciousness become rooted in itself; and then (like Jesus) chooses (from this state of autonomous agency) to ally with God, with creation.
Physical, material bodies are 'merely' the manifestation, the consequence, of a greater degree of separation, greater self-generated activity, greater agency.
Therefore, mortal incarnation is the first step towards that agency without which we cannot become full children of God. Jesus needed to become incarnate to become fully divine.
When Jesus was incarnated as a mortal - and after he had been baptised by John to commence his ministry; Jesus had the divine mode of consciousness. He was separated from the Father, and could have rejected Him. Thus, Jesus needed to make a choice, an act of will; to Love the Father, to align-with the father's creation. And of course he did.
And after death Jesus was resurrected to a permanent and incorruptible incarnation - but he remained incarnate because it is a higher mode of consciousness; and this Jesus needed to become fully-divine.
What this aims-at, what it is 'about', is divine consciousness; which is consciousness of truth and reality. More exactly; when Jesus was thinking - he thought only and always in truth and reality and with Love for it. And - because Jesus did this; this is what we can now be offered as a choice.
It was this choice and act of Jesus to align with The Father in truth and reality, in his thinking; that made it possible for our-selves to follow the same path. Once Jesus had done it, reality was changed (because Jesus's thought was reality) - now, because reality has been changed, this path and choice is universally available for anyone else to do.
We can know this directly (without any mediation of 'communication'), and for our-selves (regardless of circumstances) by thinking in the divine way; which thinking is made possible by two things: first the fact of us being children of God; and second the fact of the Holy Ghost which will show us the way, if we seek it.
In this sense, consciousness is the centre and unifying fact of the Christian scheme. It was in order that all Men could become fully-divine, children of God, that Jesus did what he did; and it was necessary for Jesus to do what he did in order for Jesus himself to become fully-divine: he needed to become incarnate, like his Father.
By recognising The Father as incarnate, we can therefore quite easily recognise why Jesus needed to become incarnate - and (at least in outline) how the incarnation of Jesus made it possible for other Men to become fully children of God.
(Note: These End Times have the characteristic of locating and amplifying what seem like small errors in Christian theology, to make them decisive in chosen damnation. The error of insisting that The Father is spirit and not incarnate was not very important in earlier times and places; but it has become important now - because it is has become the tip of a wedge that leads to rejection of the goodness of incarnation, hence to the denial of Christ's necessity to Man's salvation.)
