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 55:8-11.

15. (a) With what record is God’s display of mercy in full harmony? (b) How is God’s stated word like the rain and snow from heaven?

¹⁵ Whatever it is that Jehovah God has done in such mercy to us, he has previously given his word for it in writing in his prophecies of the Holy Bible. He means what he says, and he says what he purposes to do. So his given word is reliable, as reliable as the rain and the snow from heaven are in accomplishing the divine purpose for which they are deposited upon the earth. For that reason his stated word will not boomerang at him because of having accomplished no results. If he has given his word, then he will see to it that it is carried out by means of his almighty spirit and by means of his chosen servants. What he pleases or delights in will be done without fail according to his word. He has sent forth his word on a mission, and it will not prove to be mere empty talk. It will certainly have success in the stated mission for which he sent it.

16. In his dealings with natural Israel and with spiritual Israel, how did Jehovah prove himself to be “the God of truth”?

¹⁶ So God’s own honor is at stake in connection with his word. He cannot let it come short of its purpose, for that would mean that he is not almighty. It would mean that he is not true and is not “the God of truth.” (Psalm 31:5) His word did not fail when it came to delivering the exiled Israelites from imperial Babylon and restoring the remnant of them to their desolated homeland right on time. Nor did his word return to him without results in modern times when it came to liberating the remnant of spiritual Israel from the power of Babylon the Great and restoring them to his favor and service on earth from 1919 C.E. onward. Many other historic examples, ancient and modern, could be cited to prove the truth of his word as expressed in Isaiah 55:10, 11.
