After the U.S.S. Pueblo was captured in 1968 by the North Koreans, the 82 surviving crew members were thrown into brutal captivity. In one particular instance 13 of the men were required to sit in a rigid manner around a table for hours at a time.
After several hours, the door violently was flung open and a North Korean guard brutally beat the man in the first chair with the butt of his rifle. The next day, as each man sat at his assigned place, again the door was thrown open and the man in the first chair was brutally beaten again. On the third day the same thing happened again to the same man.
Knowing the man could not survive another beating, a young sailor took his place. When the door was flung open the guard automatically beat the new man senseless. For weeks, each day a new man stepped forward to sit in that horrible chair, knowing full well what would happen. At last, the guards gave up in exasperation. They were unable to beat that kind of sacrificial love. (Andy Grossman, via SermonFodder.com)
