Christ is like a river in another respect. A river is continually flowing, there are fresh supplies of water coming from the fountain-head continually, so that a man may live by it, and be supplied with water all his life. So Christ is an ever-flowing fountain; he is continually supplying his people, and the fountain is not spent. They who live upon Christ, may have fresh supplies from him to all eternity; they may have an increase of blessedness that is new, and new still, and which never will come to an end.
