I think C.
Nature of the beat

I love C.S. Lewis and I agree! I definitely wouldn’t want to liken prayer to a machine or pretend that there’s a “magic” method to prayer. God isn’t a vending machine. You could certainly have both ingredients — faith & expectancy — but have the wrong motives and negate your efforts. This article was intended to speak to someone assuming that they’re approaching God with pure motives. Hope that’s helpful?
