The first thing in order to appreciate a physician, is to realize that one is sick. The Saviour says the well need not a physician. It is equally true that the well care not for a physician. Sin is the disease of which Christ, as a physician, is the healer. The disease is deadly. The smallest amount is fatal. The Great Physician alone can heal it. There is no other remedy. When a man is once affected, however much he may keep it under control, and prevent its increase, there is never a diminution of the disease till the remedy of the Great Physician is applied.
