We now, then, perceive why Habakkuk has put these two things in opposition the one to the other—that the defences of this world are not only evanescent, but also bring always with them many tormenting fears—and then, that the just lives by his faith. And hence also is found a confirmation of what I have already touched upon, that faith is not to be taken here for man’s integrity, but for that faith which sets man before God emptied of all good things, so that he seeks what he needs from his gratuitous goodness: for all the unbelieving try to fortify themselves; and thus they strengthen themselves, thinking that anything in which they trust is sufficient for them. But what does the just do? He brings nothing before God except faith: then he brings nothing of his own, because faith borrows, as it were, through favor, what is not in man’s possession. He, then, who lives by faith, has no life in himself; but because he wants it, he flies for it to God alone. The Prophet also puts the verb in the future tense, in order to show the perpetuity of this life: for the unbelieving glory in a shadowy life; but the Lord will at last discover their folly, and they themselves shall really know that they have been deceived. But as God never disappoints the hope of his people, the Prophet promises here a perpetual life to the faithful.
