Fleming Rutledge writes: Sin is a category without meaning except in reference to God. A Calvin and Hobbes comic strip illustrates this in an endearing way. Calvin, a little boy, is hurtling down a snowy slope on a sled with his friend Hobbes, a tiger, conducting a discussion about sin (the wildly improbable nature of this scene is part of its charm). Here is the dialogue:

Calvin: I'm getting nervous about Christmas.

Hobbes: You're worried you haven't been good?

Calvin: That's just the question. It's all relative. What's Santa's definition? How good do you have to be to qualify as good? I haven't killed anybody. That's good, right? I haven't committed any felonies. I didn't start any wars. … Wouldn't you say that's pretty good? Wouldn't you say I should get lots of presents?

Hobbes: But maybe good is more than the absence of bad.

Calvin: See, that's what worries me.
