In my CS Lewis reader, Lewis says that Christians often think about the consequences of choices either bringing reward or punishment from God. He suggests another way to look at our choices (entry for 17 March):
I would much rather say that every time you make a choice you are turning the central part of you, the part of you 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 heavenly 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. (From Mere Christianity)
Does this not help us consider which creature we are forming as we make our many mindless choices every day?
