But, oh, how is the word its own proof, and how has it its own power, though surely nothing but the Spirit of God can give it that power in us. But in walking with God alone can we draw out its sweetness and feed upon it. I believe that the Spirit of God is a positive teacher in this respect, and may give, if He sees good, developed thoughts of its contents, but if rivers are to flow out we must drink for ourselves as thirsty for it.
