It has been said that the prophet’s call is to comfort the afflicted and to afflict the comfortable. Of course, one group will be overwhelmingly happy and the other - not so much.
It was understandable that Jeremiah didn’t want to be a prophet. He knew it was a difficult vocation. So when he called, he claimed that he was too young. God answered that he was called to be a prophet even in the womb. Can’t get any younger than that! Several times he complained to God about his lot, even to wishing he had never been born, calling down a curse on the man who announced to his father that he had a son. Apparently he abandoned his calling for a time but God was insistent. He also had to watch as one of the kings read his words and then burn them page by page, the ultimate insult. He was thrown into a cistern and left to die but was eventually rescued. He foretold the Exile and then encouraged the people in exile to settle down and have families because he would be a long time before they would return to Judah. Finally when Babylon was intent upon destroying Jerusalem, the people forced Jeremiah to flee with them to Egypt whereupon, as rumor has it, they killed him.
