Are Christians Supposed to Be Morally Superior to Non-Christians?

My brother Eric has a good answer, in five points.

His conclusion:

Perhaps we could agree: holiness of life is imperative for Christians; but the one thing we're supposed to be reflecting to the world is not our own moral lives, but Jesus himself, a friend and savior of sinners, who will readily, happily forgive and heal and rebuild and restore anyone, so that sin stops, the desert blooms, and wicked people change, to their own great happiness?
