When Johnny's dad read 1 Corinthians 6:19, 20 about our bodies being God's temple, Johnny wondered if he was living as he should. He tried to eat healthfully and get enough rest, but was this enough? Then his dad introduced him to God's four great physicians - pure air, water, proper exercise, and a clear conscience - that could keep him healthy and wise. "God's Four Great Physicians" is a fully-illustrated children's book in poetic form that teaches children simple ways to improve and maintain good health.
