I used to work in the carpet cleaning business and enjoyed success selling our pet urine removal process. I carried a high powered black light in my van and upon smelling pet odor, would ask if the homeowner would like to see the extent of the damage. Being composed of proteins, urine glows under a black light. With the lights out and shades drawn, the homeowner would follow me through their house.

Usually, there were far more spots of dried urine than the owner expected and often it could be seen on drapes, stereo speakers, the back of the couch, and splattered on walls. The reactions were often quite dramatic. One lady said, “I don’t care what it costs, just clean it up!” Another said, “I’ll never be comfortable in my home again.”


The black light didn’t cause the problem, it only revealed it. The offense was there all the time, causing a bit of a stink, but when the extent of the problem could actually be seen, most people were ready to do something about it.

We live in sin to the extent we get comfortable with it, but when the light of God’s righteous law shines upon our lives, we can see our offenses for what they really are.

It would have been cruel for me to show homeowners their problem without being able to help them. God shows us our violations of his holiness so we will accept his help. He too is in the cleaning business. By the blood of Christ our sins can be washed away and the gift of eternal life secured.

“Come now, let’s settle this,” says the LORD. “Though your sins are like scarlet, I will make them as white as snow. Though they are red like crimson, I will make them as white as wool” (Isaiah 1:18, NLT).
