“There is a preacher of the old school but he speaks as boldly as ever. He is not popular, though the world is his parish and he travels every part of the globe and speaks in every language. He visits the poor, calls upon the rich, preaches to people of every religion, and the subject of his sermon is always the same. He is an eloquent preacher, often stirring feelings which no other preacher could, and bringing tears to eyes that never weep. His arguments none are able to refute, nor is there any heart that has remained unmoved by the force of this appeals. He shatters life with his message. Most people hate him; everyone fears him.
His name? Death.
Every tombstone is his pulpit, every newspaper prints his text, and someday every one of you will be his sermon.”
