A saleswoman passed a particular corner each day on her way to work. For more than a week, she observed a little girl trying to sell a flop-eared puppy. The saleswoman finally said to the little girl, “Honey, if you want to sell this dog, I suggest you clean him up, brush his coat, raise your price, and make people think they’re getting something of value.” At noon, the saleswoman noticed the little girl had taken her advice. The puppy was groomed and sitting under a big sign that read, “TREMENDOUS Puppy for Sale – $5,000.” The saleswoman smiled and gulped, determined to tell the little girl later that she may have overpriced the puppy. To her surprise, on the way home she saw the puppy was gone! Flabbergasted, the woman sought out the little girl to ask if she had really sold the dog for $5,000. The little girl said, “I sure did, and I want to thank you for all your help.” The saleswoman spluttered, “How in the world did you do it?” She said, “It was easy. I just took two $2,500 cats in exchange!” Seriously, 2,000 years ago the greatest exchange of all time took place. On a cross outside Jerusalem, Jesus Christ gave His life in exchange for ours, “the just for the unjust, that He might bring us to God.” At the cross God took all your sin and placed it upon Christ. And when you place your trust in Christ, God takes all of His righteousness and wraps you up in it. That’s the great exchange!
