Creator and creators

Ayn Rand wrote this in The Fountainhead, through the voice of Howard Roark:

"The creators were not selfless. It is the whole secret of their power—that it was self-sufficient, self-motivated, self-generated. A first cause, a fount of energy, a life force, a Prime Mover. The creator served nothing and no one. He lived for himself.
"And only by living for himself was he able to achieve the things which are the glory of mankind." -- Ayn Rand, The Fountainhead, page 679

Man's creative capacity is the means of his survival. Acting is his own rational self-interest, his own delight and satisfaction, the individual has achieved glory. To what extent would the Christian substitute individual "creators" for the "Creator"?

The Creator was not selfless. It is the whole secret of his power—that it was self-sufficient, self-motivated, self-generated. A First Cause, a Fount of Energy, a Life Force, a Prime Mover. The Creator served nothing and no one. He lived for Himself.

And only by living for Himself was He able to achieve the things which are the glory of mankind.

I had not thought of the Creator as acting for his own satisfaction and delight until I read John Piper's book Desiring God. The subtitle, "Meditations of a Christian Hedonist,"could easily have read "Meditations of a Christian Objectivist." His entire argument seemed to say that God is self-centered. God is the highest, most glorious, focus and occupation that anyone can enjoy, and so he is focused on himself. Where Piper, consistent with the biblical theme, differs from Rand is that Rand would say the individual is the highest, most glorious focus and occupation that anyone can enjoy, so he should be focused on himself. As always, I am interested in your thoughts.
