In the "Problem of Pain," Lewis poses the question of how humans could have thought up a good God by looking at the universe and all the crap that goes on in it. It's a fair question. Then again, when I see in my everyday life, good overcoming evil (i.e., love overcoming hate), I can fathom a good God. Or when I see the beauty of the universe (although beauty is not the same as morality), I could fathom a good God who does in fact care for us.
