It means that God's Creation has not its source in any necessity; it comes from his fullness of joy; it is his love that creates, therefore in Creation is his own revealment.
God is inside you and inside everybody else. You come into the world with God. But only them that search for it inside find it. And sometimes it just manifest itself even if you not looking, or don't know what you looking for. Trouble do it for most folks, I think. ... Yeah, It. God ain't a he or a she, but a It.
Surely God would not have created such a being as man, with an ability to grasp the infinite, to exist only for a day! No, no, man was made for immortality.
