C. S. Lewis set up the case against prayer by mimicking the voice of a skeptic: “Even if I grant your point and admit that answers to prayer are theoretically possible, I still think they are infinitely improbable. I don’t think it at all likely that God requires the ill-informed (and contradictory) advice of us humans as to how to run the world. If He is all-wise, as you say He is, doesn’t He know already what is best? And if He is all-good, won’t He do it whether we pray or not?”
