That God gives man no law that is not for his best advantage, and that the interests of humanity, and the laws of purity and self-denial all lie in the same direction, and the man who does not take care of his body must fail to take the best care of his soul; for the body should be temple for God's holy spirit and the instrument to do his work, and we have no right to defile the one or blunt the other and thus render ourselves unfit for the Master's service..
