God, Who encompasses all being, created BEINGS (plural) who have everything INDIVIDUALLY, but who want to share it to increase THEIR (plural) joy.
Nothing real can be increased except by sharing. (this is very key, God HAD to share ie create in order to increase, because he was already complete, and it was HIS JOY to create).
That is why God created you (talking about you as ONE INDIVIDUAL). Divine Abstraction takes joy in sharing (notice that sharing means GIVING by creating). That is what creation means.
"How," "what" and "to whom" are IRRELEVANT, because real creation gives everything, since it can create only like itself. (God creates in his total likeness!)
Remember that in the Kingdom there is no difference between having and being, as there is in existence. In the state of being the mind gives everything always."
This is from Chapter 4, the illusions of the ego: creation and communication.
