We can claim to have supernatural love, but it's only supernatural when one would expect hatred instead. We can claim to be forgiving, but forgiveness is supernatural only when there is no earthly reason for one to be forgiving.
Compassion is supernatural when the smart thing seems to be to look out for number one.
Freedom is supernatural when one would expect to be living in a prison. Joy is supernatural when circumstances don't warrant it. Integrity is supernatural when it's normal to define values in terms of one's own background and culture. Nevertheless, as great as all this is, I really don't think that the major power of our witness is in our supernatural power and our righteousness. I think it has more to do with our honesty and vulnerability.
