Here is, I. Jeremiah's early designation to the work and office of a prophet, which God gives him notice of as a reason for his early application to that business (v. 4, 5): The word of the Lord came to him, with a satisfying assurance to himself that it was the word of the Lord and not a delusion; and God told him, 1. That he had ordained him a prophet to the nations, or against the nations, the nation of the Jews in the first place, who are now reckoned among the nations because they had learned their works and mingled with them in their idolatries, for otherwise they would not have been numbered with them, Num. xxiii. 9. Yet he was given to be a prophet, not to the Jews only, but to the neighbouring nations, to whom he was to send yokes (ch. xxvii. 2, 3) and whom he must make to drink of the cup of the Lord's anger, ch. xxv. 17. He is still in his writings a prophet to the nations (to our nation among the rest), to tell them what the national judgments are which may be expected for national sins. It would be well for the nations would they take Jeremiah for their prophet and attend to the warnings he gives them. 2. That before he was born, even in his eternal counsel, he had designed him to be so. Let him know that he who gave him his commission is the same that gave him his being, that formed him in the belly and brought him forth out of the womb, that therefore he was his rightful owner and might employ him and make use of him as he pleased, and that this commission was given him in pursuance of the purpose God had purposed in himself concerning him, before he was born: "I knew thee, and I sanctified thee," that is, "I determined that thou shouldst be a prophet and set thee apart for the office." Thus St. Paul says of himself that God had separated him from his mother's womb to be a Christian and an apostle, Gal. i. 15. Observe, (1.) The great Creator knows what use to make of every man before he makes him. He has made all for himself, and of the same lumps of clay designs a vessel of honour or dishonour, as he pleases, Rom. ix. 21. (2.) What God has designed men for he will call them to; for his purposes cannot be frustrated. Known unto God are all his own works beforehand, and his knowledge is infallible and his purpose unchangeable. (3.) There is a particular purpose and providence of God conversant about his prophets and ministers; they are by special counsel designed for their work, and what they are designed for they are fitted for: I that knew thee, sanctified thee. God destines them to it, and forms them for it, when he first forms the spirit of man within him. Propheta nascitur, non fit—Original endowment, not education, makes a prophet.
