Faith—saving faith—whatever other definition may be framed—is best described as that act of the soul by which the whole man is given over to the guardianship of the Mediator. He who thus resigns himself to Jesus avouches two things: first, his belief that he needs a protector; secondly, his belief that Christ is just that protector which his necessities require.
Saving faith is confidence in Jesus; a direct, confidential transaction with Him.
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.
The true confidence which is faith in Christ, and the true diffidence which is utter distrust of myself—are identical.
Faith then, in its relation to salvation, is that confidence by which we accept it as a free gift from the Saviour, and is the only possible way in which the gift of God could be appropriated.
We have nothing to do but to receive, resting absolutely upon the merit, power, and love of our Redeemer.
