"Programming Contest" joke

Jesus and Satan have an argument as to who is the better computer 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 hours, 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 when the power is restored, 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 us see if 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. He stutters, "But how? I lost everything, yet Jesus'
program is intact! How did he do it?"
God looked at Satan and smiled. "Jesus saves."
