Through Isaiah, God provides this assurance: “Just as the pouring rain descends, and the snow, from the heavens and does not return to that place, unless it actually saturates the earth and makes it produce and sprout, and seed is actually given to the sower and bread to the eater, so my word that goes forth from my mouth will prove to be. It will not return to me without results, but it will certainly do that in which I have delighted, and it will have certain success in that for which I have sent it. ” ​ — Isaiah 55: 10, 11.
Jesaja kaudu andis Jumal järgmise kinnituse: ” Otsekui vihm ja lumi tuleb taevast alla ega lähe sinna tagasi, vaid kastab maad ja teeb selle sigivaks ning kandvaks, et see annaks külvajale seemet ja sööjale leiba, nõnda on ka minu sõnaga, mis lähtub mu suust: see ei tule tagasi mu juurde tühjalt, vaid teeb, mis on mu meele järgi, ja saadab korda, milleks ma selle läkitasin! ”.
