But if it be God’s singular gift, to turn a pure lip to the nations, it follows that faith is conferred on us by him, for both are connected together. As God then purifies the hearts of men by faith, so also he purifies their lips that his name may be rightly invoked, which would otherwise be profaned by the unbelieving. Whenever they pretend to call on God’s name, it is certain that it is not done without profanation.
