A friend was updating me on his past year—a year in which he had been receiving ongoing medical treatment for cancer. The smile on his face was a powerful testimony to the good news he had just received. He said that at his one-year checkup the doctor announced that the test results all pointed to one thing: “You are totally clean!” What a difference two words can make! To my friend, totally clean meant every trace of the disease that had threatened his life only months before had been wiped from his body. We rejoiced to hear that he was totally clean!
