The things of God are of deep import; and time, and experience, and careful and ponderous and solemn thoughts can only find them out. Thy mind, O man!... must stretch as high as the utmost heavens, and search into and contemplate the darkest abyss, and the broad expanse of eternity - thou must commune with God.
