Jesus and Satan were having an argument as to who was the better programmer. This went on for a few hours until they agreed to hold a contest with God as the judge. They sat at their computers and began.
They typed furiously for several hours, lines of code streaming up on the screen.
Seconds before the end of the competition, a bolt of lightning struck, taking out the electricity. Moments later, the power was restored, and God announced that the contest was over. He asked Satan to show what he had come up with. Satan was visibly upset, and cried, "I have nothing! I lost it all when the power went out."
"Very well, then," God said, "Let us see if Jesus did any better."
Jesus entered a command, and the screen came to life in vivid display, the voices of an angelic choir poured forth from the speakers.
Satan was astonished. He stuttered, "But how?! I lost everything, yet Jesus' program is intact! How did he do it?"
God chuckled. "Jesus Saves" he said.
