To explain how Christ in us now labors to make us more human, not less, pastor/author Rankin Wilbourne used the following illustration:

Consider two superheroes, Batman and Spider-Man. Batman is a rich and strong man with lots of cool gadgets. His superpowers stem from his external possessions. Spider-Man has a few accessories as well, but he is a superhero because of the spider powers he obtained when he was bitten by a radioactive spider. His nature has been changed. Now he has a new power accessible to him, within him.

Christ in you makes you more like Spider-Man than Batman. Something alien to you, from outside of you, has entered into you and changed your nature. You now have power that you did not have before. The trouble with this analogy is that Spider-Man became something more than human, while we instead are being restored to our full humanity. We are becoming more like Christ.
