You worship that which you don't know. We worship that which we know; for salvation is from the Jews.
      First, That the water of Jacob's well yielded but a transient satisfaction and supply: "Whoso drinketh of this water shall thirst again. It is no better than other water; it will quench the present thirst, but the thirst will return, and in a few hours a man will have as much need, and as much desire, of water as ever he had." This intimates, 1. The infirmities of our bodies in this present state; they are still necessitous, and ever craving. Life is a fire, a lamp, which will soon go out, without continual supplies of fuel and oil. The natural heat preys upon itself. 2. The imperfections of all our comforts in this world; they are not lasting, nor our satisfaction in them remaining. Whatever waters of comfort we drink of, we shall thirst again. Yesterday's meat and drink will not do to-day's work.
