“faith” to “wavering,” he very aptly expresses its nature. And equally worthy of attention is what he adds, that they avail nothing, who call upon God in perplexity and doubt, and are uncertain in their minds whether they shall be heard or not; whom he even compares to waves, which are variously tossed and driven about with the wind. Whence he elsewhere calls a legitimate prayer “the prayer of faith.”[300] Besides, when God so frequently affirms, that he will give to every man according to his faith, he implies that we can obtain nothing without faith. Finally, it is faith that obtains whatever is granted in answer to prayer. This is the meaning of that famous passage of Paul, to which injudicious men pay little attention: “How shall they call on him, in whom they have not believed? And how shall they believe in him, of whom they have not heard? So then faith cometh by hearing, and hearing by the word of God.”[301] For by a regular deduction of prayer originally from faith, he evidently contends, that God cannot be sincerely invoked by any, but those to whom his clemency and gentleness have been revealed and familiarly discovered by the preaching of the gospel. XII. This necessity our adversaries never consider. Therefore, when we inculcate on believers a certain confidence of mind that God is propitious and benevolent towards them, they consider us as advancing the greatest of all absurdities. But if they were in the habit of true prayer, they would certainly understand, that there can be no proper invocation of God without such a strong sense of the Divine benevolence. But since no man can fully discover the power of faith without an experience of it in his heart, what advantage can arise from disputing with such men, who plainly prove that they never had any other than a vain imagination? For the value and necessity of that assurance which we require, is chiefly learned by prayer; and he who does not perceive this, betrays great stupidity of conscience. Leaving, then, this class of blinded mortals, let us ever abide by the decision of Paul, that God cannot be called upon, but by those who receive from the gospel a knowledge of his mercy, and a certain persuasion that it is prepared for them. For what kind of an address would this be? “O Lord, I am truly in doubt, whether thou be willing to hear me; but since I am oppressed with anxiety, I flee to thee, that if I be worthy thou mayest assist me.” This does not resemble the solicitude of the saints, whose prayers we read in the Scriptures. Nor is it agreeable to the teaching of the Holy Spirit by the apostle, who commands us “to come boldly to the throne of grace, that we may find grace;”[302] and informs us, that “we have boldness and access, with confidence, by the faith of Christ.”[303] This assurance of obtaining what we implore, therefore, which is both commanded by the Lord himself, and taught by the example of the saints,
