Edited from The Resolution of Grief, an essay published in The Great Gift (1977) by William Arkle:
From what I understand, the motivation for the whole of creation is that out of it should come a number of individuals who have chosen their own unique path to individuality and therefore become true unique individuals.
The Creator longed for many of these true individuals to choose to realise 'Himself' and 'Herself' as a father and mother and as a friend; should choose to relate to this Creator as a friend, not so much as a God, but more as a friend.
The more we grow in our understanding of our own reality and 'the gift', and the attitude behind the gift, from the Creator's position, the more we shall become able to take up this position of divine friendship with our Creator as well as with one another.
We shall be able to take up this position of divine friendship because, in our desire to read the heart of the Creator, we shall become more and more certain that it is the deepest thing that the Creator longs for.
And with any friend this is the only motive we have - it is to read the deepest level of their Being and help to fulfil for them the deepest longings in their Being.
This is what friends long to do for one another. It is a very creative activity, and out of it comes an endless series of creative attitudes and creative activities.
Notes from BGC:
This is apparently a very different understanding of God's motivation than most religious people have held throughout history. This is the insight that God wants that there be more gods with whom he can can live in loving and creative 'friendship'.
(Although friendship as commonly used is too weak a word - a model for this friendship is an ideal and eternal version of the love between grown-up children and their parents; this extended family working together - and with other families - on all the tasks and joys of living.)
This is a personal motivation of God; and God is therefore envisaged as a person - indeed as two persons: the primal Father and Mother.
This entails that at the very bottom of reality, at the most fundamental level; reality consists of Beings; and the most important thing about the Beings is their relationships - specifically their love. And the most important thing that these loving Beings do is creating.
So 'the creation' is actually an 'ing' not an 'ion' - creation wasn't done, it is doing; and the hope of God is that we will choose to become - like our Heavenly parents - engaged in that doing.
This raises the point of 'true individuals', and that they cannot be 'made' but at most 'encouraged' and 'educated'. This world is made as a place where people can each have the experiences they most need to learn from (if they so choose), to learn and grow towards fuller godhood.
The need of creation is for individuals who are capable of love and have chosen love; and who are also capable of true creation - which is (to be valuable) something to which each individual brings something unique...
We create from our uniqueness. Being an individual is an essential part of the plan; in other words, God has as many plans as individuals - and each plan is a collaboration.
Therefore, the nature of this world is such as to encourage each of us to develop that creative uniqueness - within a context of love.
