When a miner looks at the rope that is to lower him into the deep mine, he may coolly say, "I have faith in that rope as well made and strong." But when he lays hold of it, and swings down by it into the tremendous chasm, then he is believing on the rope. Then he is trusting himself to the rope. It is not a mere opinion - it is an act. The miner lets go of every thing else, and bears his whole weight on those well braided strands of hemp. Now that is faith.
