C. S. Lewis’s The Great Divorce is one of my favorite books, as it depicts a fanciful journey from hell to heaven so that those in hell can see what they have missed. Any Lewis book is full of pithy insights. Here’s one from The Great Divorce that I find particularly lucid:
There are only two kinds of people in the end: those who say to God, “Thy will be done,” and those to whom God says, in the end, “Thy will be done.” All that are in Hell, choose it. Without that self-choice there could be no Hell.
