Faith comes by hearing and hearing by the word of God. Therefore the word of God is the only means of faith. Therefore, where there is no word of God there cannot be any faith. And where the word of God is, faith is entire dependence upon that word for the accomplishment of what that word says. From all this, which is the truth, it is perfectly plain that in order for anyone to ask in faith, he must first of all be sure that he has the word of God for what he asks.
Faith is complete dependence upon the word of God only, for the accomplishment of what that word says. This being so, it must never for a moment be forgotten that where there is no word of God, there can not be any faith. This is shown also in the truth that "faith cometh by hearing, and hearing by the word of God." Rom. 10:17. Since faith thus comes indeed by the very word of God itself, it is perfectly plain that where there is no word of God, there can be no faith.
Since faith is the depending upon the word of God only, for what that word says, being justified by faith is simply being accounted righteous by depending upon the word only. And since the word is the word of God, dependence upon the word only is dependence upon God only, in the word. Justification by faith, then, is justification -- being accounted righteous by dependence upon God only, and upon him only because he has promised.
