Pastor and author John Ortberg shares this humorous story that pointedly conveys the truth about human nature.

Many years ago, early on in our marriage, my wife and I sold our Volkswagen Beetle to buy our first really nice piece of furniture. It was a sofa. It was a pink sofa, but for that kind of money, it was called a mauve sofa. The man at the sofa store told us all about how to take care of it, and we took it home.

We had very small children in those days, and does anybody want to guess what was the Number One Rule in our house from that day on? "Don't sit on the mauve sofa! Don't play near the mauve sofa! Don't eat around the mauve sofa! Don't touch the mauve sofa! Don't breathe on the mauve sofa! Don't think about the mauve sofa! On every other chair in the house, you may freely sit, but on this sofa—the mauve sofa—you may not sit, for on the day you sit thereon, you will surely die!"

And then one day came the "Fall." There appeared on the mauve sofa a stain…a red stain…a red jelly stain. My wife called the man at the sofa factory, and he told her how bad that was. So she assembled our three children to look at the stain on the sofa: Laura, who then was about 4, and Mallory, who was about 2½, and Johnny, who was maybe 6 months. She said, "Children, do you see that? That's a stain. That's a red stain. That's a red jelly stain. And the man at the sofa store says it's not coming out, not for all eternity. Do you know how long eternity is, children? Eternity is how long we're all going to sit here until one of you tells me which one of you put the red jelly stain on the mauve sofa."

For a long time they all just sat there until finally Mallory cracked. I knew she would. She said, "Laura did it." Laura said, "No I didn't." Then it was dead silence for the longest time. And I knew that none of them would confess putting the stain on the sofa, because they had never seen their mom that mad in their lives. I knew none of them was going to confess putting the stain on the sofa, because they knew if they did, they would spend all of eternity in the "Time Out Chair." I knew that none of them would confess putting the stain on the sofa, because in fact, I was the one who put the stain on the sofa, and I wasn't sayin' nuthin'! Not a word!

Ortberg turns from that to say, "Here's the truth about us. We've all stained the sofa."
