Quote by John A. Widtsoe
"... the condition of the body limits, largely, the expression of the spirit. The spirit speaks through the body and only as the body permits. ... Hence, if the body is in poor condition from birth, man must strengthen it as the days increase; if it is strong from the beginning, he must make it stronger."
