Jesus and Satan have a discussion as to who is the better computer programmer.  This goes on for hours until they come to an agreement to hold a contest, with God as the judge.

They sit down before their computers and begin.  They both type furiously, lines of code streaming up the screens for several hours straight. Just seconds before the end of the competition, a bolt of lightning strikes, taking out the electricity.  Moments later the power is restored, and God announces that the contest is over.  He asks Satan to show what he has come up with.

Satan is visibly upset, and cries, "I have nothing!  I lost it all when the power went out." "Very well, then," says God. "Let's see if Jesus fared any better."

Jesus enters a command, and the screen comes to life in a perfect display, along with voices of an angelic choir pouring forth from the speakers. Satan is astonished.  He stutters, "B-b-b-but how can that be?  I lost everything, yet Jesus' program is intact.  How could he have done that?"

God just smiled and replied, "Jesus saves."
