From the day of his call to the close of his ministry, Jeremiah stood before Judah as "a tower and a fortress" against which the wrath of man could not prevail. "They shall fight against thee," the Lord had forewarned His servant, "but they shall not prevail against thee: for I am with thee to save thee and to deliver thee, saith the Lord. And I will deliver thee out of the hand of the wicked, and I will redeem thee out of the hand of the terrible." Jeremiah 6:27; 15:20, 21.

Fra den dag, Jeremias blev kaldet, til han sluttede sin gerning, var han "metalprøver" og "guldprøver" blandt folket for at kende og prøve deres færd, og menneskers vrede kunne ikke få bugt med ham. Herren havde på forhånd sagt til sin tjener: "De skal kæmpe imod dig, men ikke få overhånd over dig, thi jeg er med dig for at frelse og redde dig, lyder det fra Herren. Jeg redder dig af ondes vold og frier dig af voldsmænds hånd." Jer. 6,27; 15,20-21.
