Computers in the Eternities

Do you ever lie awake at night wondering if God uses a computer?

And then conclude that sometimes computers seem to be possessed, and if they are possessed then the Devil must use them. So, if they are of the Devil, then they can't be of God. And God isn't going to use anything that is of the Devil. So, God must not use a computer.

But then, after all that, you realize that God is perfect, so why would He need a computer anyway.
