A funny coincidence that this is the second time in as many days that I’ve read an overtly Christian themed sentence with the word “refuse” in it.
A man can no more diminish God’s glory by refusing to worship Him than a lunatic can put out the sun by scribbling the word ‘darkness’ on the walls of his cell.
My first encounter with this quote fairly cinched my already poisoned opinion of C.S. Lewis. The addition of the word “lunatic” is a graceful, if off-putting touch. As an aside, you might wonder how often the word occurs in literature and with what other words and concepts it is most frequently paired.
His reasoning is circular and simply begs the question. He flinches just at the point where he could have been brilliant or brave. He might have more truthfully stated that a man can no more make his gods exist — by his own aggressive insistence — than said lunatic can claim knowledge from scribbling ‘know’ on the same prison wall.
