The Devil

One day in Heaven, Jesus and Satan are bickering nonstop about which of them is better than the other. God says “ENOUGH! We’re going to settle this right now. Whoever can fill up an Excel spreadsheet with the most souls within 24 hours will officially be considered THE BEST.”

So Jesus gets on his computer and starts meticulously typing in the names of each soul, one-by-one, line-by-line, at his own slow and steady pace. Satan on the other hand is using macros and going on the dark web and illegally downloading thousands of lists of souls and is just filling out his spreadsheet with all these different names. He’s feeling all cocky and arrogant. “There’s no way Jesus can ever get more souls than me!”

But then, with only 5 minutes to spare, the power in Heaven goes out and comes back on. When Satan looks at his computer screen, everything is empty!  Satan is fuming with anger and cursing after every breath. “It’s not fair, it’s not fair! I had so many souls! How could he have won?!”

God then stops him and says “Satan, listen… Jesus saves.”
