The purely material world seems to have more in common than we with the unchanging and everlasting years of the Great Creator. Yet we know that it is not so. In reality the rocks are less enduring than man. Each man's personal self will still survive for weal or woe, when another catastrophe shall have utterly changed the surface of this planet, and the elements shall have melted with fervent heat, and the earth also and all things that are therein shall have been burnt up.
