I used to think that God was a Mathematician. I now think that He only took it on as a serious hobby to be indulged at the end of a long and busy day. "Good -- that's One. Good, that's Two. Good, that's Three," and so forth. After getting to Six, He could see where it was going, and was tired. "Here comes Seven, and I'm taking a rest from all that." Maybe He delegated that whole business of Mathematics to the Archangels, at least for a while.
After a long, restful Sabbath He aroused Himself and had other things on His mind. Like Adam. And a Garden with Trees.
