5, 6. At the end of World War I, in the face of the postwar work that lay ahead of them, the surviving remnant of Jehovah’s people felt like what prophet who faced the destruction of Jerusalem in his lifetime?

⁵ After World War I ended in 1918, the circumstances of the remnant of spiritual Israelites and the work ahead of them took on a likeness to those of a young man over there in the turbulent Middle East. He was a Jewish priest named Jeremiah the son of Hilkiah. The city of Jerusalem, in the temple of which he served as a priest, was doomed to destruction within his own lifetime. No less does Christendom, which claims to be the spiritual counterpart and the supplanter of ancient Israel in God’s favor, face early destruction, immediately before the “war of the great day of God the Almighty” at Har–Magedon. As a survivor of the destruction of the Jerusalem of the seventh century before our Common Era, Jeremiah was able, under inspiration, to write the book of Lamentations over its ruins.

⁶ When the prophetic work was set before the young Jeremiah, he said: “Alas, O Sovereign Lord Jehovah! Here I actually do not know how to speak, for I am but a boy.” But Jeremiah was told: “Do not say, ‘I am but a boy.’ But to all those to whom I shall send you, you should go; and everything that I shall command you, you should speak. Do not be afraid because of their faces, for ‘I am with you to deliver you,’ is the utterance of Jehovah.”​—Jeremiah 1:4-8.

7. (a) Jeremiah was to serve as a prophet to how many, and in behalf of how many does a “prophet” need to serve today? (b) Does his serving to this extent mean that he will have success with respect to the nations, or in whose behalf is consideration still being shown?

⁷ Jeremiah was to perform the part of a full-grown man, for what his God inspired him to write was to be of importance to all mankind, even today. A “prophet to the nations” is what Jehovah made him. (Jeremiah 1:5)

10. Jeremiah’s surviving the fall of Jerusalem prefigured what, and shortly after the latter, what effort by the nations will fail?

¹⁰ Jeremiah survived the fall of Jerusalem and her realm in 607 BCE, this confirming him as being Jehovah’s true mouthpiece;
