Commentary on Isaiah Volume 2 John Calvin
COMMENTARY ON ISAIAH
he promises in his word; for we look upon the word, as if it were suspended in the air and had no effect. How shocking this is, he demonstrates from the very course of nature; for it is in the highest degree unreasonable to ascribe less to the word than to a dumb creature; and therefore he teaches us, that his word never fails of its effect. Some understand this to mean that the preaching of the Gospel is never unprofitable, but always produces some fruit. This is true in itself; for the Lord worketh by his Spirit, and "giveth increase," (1 Corinthians 3:7) so that the labor of his servants is not unproductive. But the Prophet's meaning was different; namely, that God does not speak in vain or scatter his promises into the air, but that we shall actually receive the fruit of them, provided that we do not prevent it by our unbelief.
But watereth the earth, and causeth it to bring forth. He mentions two effects produced by the watering of the rain, which fertilizes the earth; first, that men have abundance of food for their support; and secondly, that they have seed for procuring a crop in the following year. If therefore in things of a transitory nature the power of God is so great, what must we think of the word? 333
11. So shall my word be. The word goeth out of the mouth of God in such a manner that it likewise "goeth out of the mouth" of men; for God does not speak openly from heaven, but employs men as his instruments, that by their agency he may make known his will. But the authority of the promises is more fully confirmed, when we are told that they proceed from the sacred mouth of God. Although, therefore, he brings forward witnesses from the earth, he declares that all that they have promised shall be ratified and sure; and, in order to impress more deeply on the minds of men the power and efficacy of preaching, he declares that he does not cast that precious seed at random, but appoints it for a fixed purpose, and consequently that we ought to entertain no doubt as to the effect; for there is nothing to which mortals are more prone than to judge of God from themselves so as to withhold belief from his voice.
This doctrine must be frequently repeated and inculcated, that we may know that God will do what. he hath once spoken. For this reason, when we hear the promises of God, we ought to consider what is his design in them; so that, when he promises the free pardon of our sins, we may be fully assured that we are reconciled through Christ. But, as the word of God is efficacious for the salvation of believers, so it is abundantly efficacious for condemning the wicked; as Christ also teacheth, "The word which I have spoken, that
333"These words depend on what goes before, and their meaning may thus be briefly stated. Let not the people refuse to believe that a wicked man, after having committed great crimes, shall suddenly be saved. For my thoughts are not as the thoughts of men; and as far as heaven is distant from the earth, so are my thoughts separated from the thoughts of men. I am most merciful and ready to forgive. Would you wish to have another metaphor? As the rain and snow come down from heaven, and do not return thither, but water and refresh the earth, and cause it to bring forth various productions, that the corn-fields may produce abundance of bread for the use of men; so the word of my promise, which I have promised once and again, and which hath gone out of my mouth, shall not be void, but all shall be actually fulfilled." — Jerome.
