Ruth Bell Graham is buried on the grounds of The Billy Graham Library. She was born in China, where her parents served the Chinese people through their medical expertise. The Chinese symbol on her gravestone is "righteousness," which is made up of two other symbols: the symbol for lamb over the symbol for me. Over 1000 years bC the idea of sacrifice and atonement were written into the Chinese language.
