From the wisdom of Calvin Miller*:

One winter I was leading a student conference in Canada when I met the son of a prestigious physician.  He was wearing a heavy and handsome winter coat.  “Nice coat!” I said.

“Thank you,” he replied.

In further discussion, I discovered that it had been purchased at a secondhand store for twenty-five cents.  “Why did you buy a secondhand coat?” I asked the son, out of earshot of his famous father, “Your father is rich!”

“Because my father also buys secondhand coats,” the young man answered.

I listened long enough to discover that the physician had reevaluated his whole economic position and had led his sons in the same new direction.  They honored the lordship of Christ by dressing in other people’s castaways.  They used the money they might have spent on new clothes to travel to Third World countries to practice medicine.  Fettered to this great commitment, the doctor had yet liberated himself and his sons.  Such freedom as they know is only gained as we break our ties to our material ambitions and yield to the Savior.
