What Lewis Is Saying About Christian Behavior

The way you behave reflects the kind of people we are. Lewis spends so much time at the beginning of mere Christianity talking about this difficulty in actually doing what we know to be good. He is there setting up a question he'll come back to again and again, which is how on earth can we do good when we can't do good? The answer has to be personal transformation. That's to be some inward change in us. And once you see that, then the whole idea of Christian behavior can be seen in a very different way.
