People often think of Christian morality as a kind of bargain in which God says, "If you keep a lot of rules, I'll reward you, and if you don't I'll do the other thing." I do not think that is the best way of looking at it. I would much rather say that every time you make a choice you are turning the central part of you, the part that chooses, into something a little different from what it was before. And taking your life as a whole, with all your innumerable choices, all your life long you are slowly turning this central thing either into a Heaven creature or into a hellish creature: either into a creature that is in harmony with God, and with other creatures, and with itself, or else into one that is in a state of war and hatred with God, and with its fellow creatures, and with itself. To be the one kind of creature is Heaven: that is joy, and peace, and knowledge, and power. To be the other means madness, horror, idiocy, rage, impotence, and eternal loneliness....
