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.
