God aims at our salvation and also at our theosis. For God's ultimate goals to be achieved, that is the reason behind Creation, both salvation and theosis need to happen in as many individuals as possible.
(The plan works no matter how few individuals, but each individual who does Not choose salvation and theosis is a loss compared with what might have been possible.)
Salvation is when someone chooses Heaven: that is, chooses to follow Jesus Christ through death to immortal resurrection.
Theosis is the process of raising the level of consciousness - from the immersive and passive to the free and agent.
There can be salvation without theosis, as when someone chooses Heaven but chooses to remain spiritually 'a child'.
Theosis can occur without salvation, as when a mortal Man rises in freedom and agency, becomes truly creative as an individual, 'grows-up' to some extent; but rejects Heaven.
Theosis is to develop consciousness of a divine nature, towards the goal of reaching a level of participation in the work of divine creation.
But without salvation, the attainable level of theosis cannot be high - because the individual's creation must be harmonious with divine creation in order to be taken-up into it and to exist eternally. Otherwise, individual creativity is a temporary and labile thing of men's minds only.
Harmony-with divine Creation comes from Love of God, Good and God's Creation - which for mortal Men can be simplified to love of, faith in, trust in, the (always potentially present, as the Holy Ghost) person of Jesus Christ.
The fullness of creation from a Man is when creation comes actively, personally, originally, as a product of our divine selves, in harmony with God's creation, that harmony coming-from our love of God and creation.
There is no System, ultimately. And we are coming to realise that.
System and Symbol were important to our ancestors; but for us they are losing their power and generality - a spiritually-effective system nowadays is likely to be personal, idiosyncratic - and that in itself limits the effectiveness of the system.
In practice, now; system increasingly equates with bureaucracy; so that dependence on any system will usually (and eventually certainly will) be captured and turned; bureaucracy will subvert then dictate symbol; insistence on specifci symbolism will lead to monitoring and control systems... And any specific system will converge onto/into 'the single linked bureaucracy' of Global totalitarianism.
So, for us, we must cease to depend on system - on pain of being drawn into the instrument of purposive (demonic) evil...
As bottom line, all system and symbol must be disposable; there should eventually be no system; because there is no system of creation (nor of love).
Individual creativity (like love) is a 'product' of A Being, not a system.
True, everlasting and universal creativity is an overflow of the self, motivated by love; harmoniously enhancing God's original and continuing Creation.
