Researchers at Duke University Medical Center studied 1700 older Americans and discovered that those who regularly attended religious services had stronger immune responses that those who did not. Blood test showed that attending church raised their level of immunity against disease. So believers are healthier in body as well as soul! Of course, attending church will never give you immunity from temptation, but it will make your resistance to temptation much stronger and you will be far less likely to yield to it.
