The Famous Jesus Saves Joke

Jesus and Satan have an argument as to who is the better programmer. This goes on for a few hours until they agree to hold a contest with God as the judge.
They set themselves before their computers and begin. They type furiously for several lines of code streaming up the screen. 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 had 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 us see it Jesus fared any better."
Jesus enters a command, and the screen comes to life in vivid display, the voices of an angelic choir pour forth from the speakers.
Satan is astonished. and stutters, "But how?! I lost everything, yet Jesus' program is intact! How did he do it?"
God chuckles, "Jesus saves."
