Meanwhile Jeremiah was growing old in years and older in experience. When Jehoiakim died, it was nearly forty years since the young priest had first been called "to pluck up and to break down, and to destroy and to overthrow; to build and to plant"; it was more than eleven since his brighter hopes were buried in Josiah's grave. Jehovah had promised that He would make His servant into "an iron pillar and brasen walls."[88] The iron was tempered and hammered into shape during these days of conflict and endurance, like-- " ... iron dug from central gloom, And heated hot with burning fears And dipt in baths of hissing tears, And battered with the shocks of doom, To shape and use." He had long lost all trace of that sanguine youthful enthusiasm which promises to carry all before it. His opening manhood had felt its happy illusions, but they did not dominate his soul and they soon passed away. At the Divine bidding, he had surrendered his most ingrained prejudices, his dearest desires. He had consented to be alienated from his brethren at Anathoth, and to live without home or family; although a patriot, he accepted the inevitable ruin of his nation as the just judgment of Jehovah; he was a priest, imbued by heredity and education with the religious traditions of Israel, yet he had yielded himself to Jehovah, to announce, as His herald, the destruction of the Temple, and the devastation of the Holy Land. He had submitted his shrinking flesh and reluctant spirit to God's most unsparing demands, and had dared the worst that man could inflict. Such surrender and such experiences wrought in him a certain stern and terrible strength, and made his life still more remote from the hopes and fears, the joys and sorrows of common men. In his isolation and his inspired self-sufficiency he had become an "iron pillar." Doubtless he seemed to many as hard and cold as iron; but this pillar of the faith could still glow with white heat of indignant passion, and within the shelter of the "brasen walls" there still beat a human heart, touched with tender sympathy for those less disciplined to endure. We have thus tried to estimate the development of Jeremiah's character during the second period of his ministry, which began with the death of Josiah and terminated with the brief reign of Jehoiachin. Before considering Jeremiah's judgment upon this prince we will review the scanty data at our disposal to enable us to appreciate the prophet's verdict.
