That towel served mostly as a decoration for a few years until one of my daughters accidentally used it to clean the car. The commemorative towel has been scrubbed with stain remover and sent through the washer, but it's indelibly marked by grease and grime. At first I was miffed at having my memento used to wash hubcaps and bumpers. But then I began to see that towel as a picture of myself, and it caused me to ask some questions. My little towel now serves as a reminder that self-preservation will keep me untouched but completely useless in my service for Christ.
Real servants get dirty every day.
