In its common usage, a black light reveals that which is invisible to the naked eye--exposing contaminants that produce otherwise undetectable odors. Black lights can also be used to distinguish between genuine currency and counterfeit bills. God too has a way of exposing man and showing us who we really are beneath the surface. He illuminates the emptiness in the cups we fill with temporal pleasures; unearths the unredeemed areas of our lives that we bury under rhetoric; and graciously provides us with the hope of a day where all that we now desire to hide is perfected by his sin-eradicating power.
