C.S. Lewis once made a vivid observation that grumblers are on a path to becoming just a grumble: “[Hell] begins with a grumbling mood and yourself still distinct from it: perhaps criticizing it. And yourself, in a dark hour, may will that mood, embrace it. Ye can repent and come out of it again. But there may come a day when you can do that no longer. Then there will be no you left to criticize the mood, just the grumble itself going on forever like a machine.”
