Jeremiah 1:5

Before I formed thee in the belly, I knew thee, before ever his conception had taken place, the Lord had destined him to be His prophet; and before thou camest forth out of the womb, I sanctified thee, separating and consecrating him, setting him apart for the sacred office, and I ordained thee a prophet unto the nations, not only to the people of Judah and Jerusalem, but to other nations as well. Jeremiah's choice of his calling was not the result of meditation and reflection, of a false enthusiasm and ecstasy, but of a supernatural revelation, of a selection on the part of God, which was in no way influenced by any ability or disposition on the prophet's part.
