You will recall that every time Clark Kent transformed himself into Superman, he would go into a telephone booth and strip off his ordinary business suit, revealing his official Superman costume. He could only stop locomotives and lift skyscrapers when he was properly clothed in the outfit that revealed his true identity. As Christians, we can do no mighty deed unless we are properly clothed with the Spirit of God, which discloses our true spiritual selves and supplies the power to do wondrous things.
