There's a reason why it took God six days to create the universe. The job started on Monday. The carpenters and construction people would show up each morning, work for a while, then disappear, claiming they needed more supplies to get the job finished.
The plumbers and electricians kept promising to be there right away, and when they didn't show up, God had to chase after them all over creation before they would respond.
Friday came by and everybody was halfway finished and claiming they needed Saturday to finish it all up. God was displeased. He didn't want to pay time-and-a-half for a job that should have been finished on Thursday. But in the end He had no choice but to give the go-ahead signal to get it all finished, as long as everyone understood He was going to raise Hell if the job wasn't done right. Sunday God rested, because He needed the rest.
