"The design of the universe ... is very magnificient and shouldn’t be taken for granted. In fact, I believe that is why Einstein had so little use for organized religion, although he strikes me as a basically very religious man. He must have looked at what the preachers said about God and felt that they were blaspheming. He had seen much more majesty than they had ever imagined, and they were just not talking about the real thing. My guess is that he simply felt that religions he’d run across did not have the proper respect... for the author of the universe."
I highly recommend "Let the Nations Be Glad" by John Piper.
