The topic now before us is the use of illustrations in our sermons. Perhaps we shall best subserve our purpose by working out an illustration in the present address; for there is no better way of teaching the art of pottery than by making a pot. Quaint Thomas Fuller says, "Reasons are the pillars of the fabric of a sermon; but similitudes are the windows which give the best lights." The comparison is happy and suggestive, and we will build up our discourse under its direction.
